Advanced Photovoltaics for SpaceMentor: Alec James Jackson, Space Vehicles
Location: Kirtland
Academic Level: Masters, Ph.D.
Virtually every spacecraft flying uses photovoltaics (aka solar cells) to provide electrical power. Advances in single crystal multi-junction, thin-film, and nano-technology based photovoltaics are important to achieving improved on-orbit performance. The current state of the art photovoltaic cells used for space applications are based on the III-V material systems (eg. GaAs, GaInP). However, innovative and novel material systems capable of more effectively utilizing the solar spectrum could provide tremendous advantages for space missions. For example, recent work examining nano-structures have shown interesting advancements. Some areas of interest for this topic include space environmental effects, electro-optical properties, and performance parameters for candidate material systems. Specific projects can be tailored to students’ interests and skills, but will require a basic understanding of electrical, optical, and materials properties. Students selected for this research opportunity will work with their mentor to develop a productive work plan which will be synergistic with their field of study and the Air Force Research Laboratory’s mission.

Contact mentorAnomaly Detection with Single-Pixel Cameras
Mentor: Anthony Giljum, Space Vehicles
Location: Kirtland
Academic Level: Masters, Ph.D.
Compressive single-pixel imaging is a signal processing paradigm wherein high-resolution scenes are
recovered from highly subsampled, randomly spatially multiplexed data acquired on a single detector.
While this allows for scenes to be imaged at sub-Nyquist rates, recovery becomes an iterative process
with high compute requirements. For this reason, extracting information from the randomly multiplexed
measurements themselves, without reconstruction, is highly desirable. One valuable piece of
information is whether a static scene experienced any significant changes, called anomalies, over the
course of the measurement. In this project, the student will develop novel methods for detecting and
localizing anomalies from single-pixel measurements using time-series analysis and neural networks.

Contact mentorAtomic Oxygen - Surface Interactions
Mentor: Benjamin Douglas Prince, Space Vehicles
Location: Kirtland
Academic Level: Masters, Ph.D.
Low Earth Orbit (LEO) in Earth's atmosphere contains a number of atomic and molecular species, both uncharged and ions. As a spacecraft operates in LEO, the atmosphere serves as a source of drag on the velocity of the spacecraft leading to altitude variations over time. One significant source of this drag is the atomic oxygen concentration, which can vary significantly with various conditions (e.g. daytime vs nighttime) . The measurement of neutrals often involves instruments with significant size, weight and power requirements which often make it impractical to make in situ space measurements. In this project, the student will examine atomic oxygen collisions with various materials in a high vacuum environment so as to impart a response on either the surface or the oxygen collision partner that can lead to quantification of the number density of atomic oxygen. The student will compare and quantify the measured response to the state-of-the-art capabilities and assess whether these materials improve the state-of-the-art or should no longer be explored.

Mentor: Jeanne M Riga, Directed Energy
Location: Kirtland
Academic Level: Masters, Ph.D.
Carbon fiber and nanotubes materials have been explored as cathodic coatings due to their high thermal and electrical conductivities and aspect ratios. A significant barrier to achieving theoretical performance of these coatings is the interface between the fiber/nanotube and the structural substrate material.

Participant will develop workflow to explore structure of this interface and calculate corresponding electronic properties of interface structure.
Contact mentorAttitude control of flexible-body spacecraft
Mentor: Andrew James Sinclair, Space Vehicles
Location: Kirtland
Academic Level: Upper-level Undergraduate
Recent advancements in deployable structures are enabling mission concepts for large deployable apertures, i.e. antennas and solar panels. However, large deployable structures can have high flexibility, with modal frequencies approaching the bandwidth requirements for even low-precision attitude control. The fact that the flexible modes of deployable structures can be difficult to model prior to launch makes the controller-design problem even more difficult. The goal of this project is to develop control methodologies that exploit the large trade space in sensors, actuators, and control objective. Sensors can be limited to traditional attitude and angular-velocity sensors, or also include measurements of the flexible-body motion (i.e. strains or displacements). Actuators can be limited to applying a single torque to the spacecraft, or allow multiple actuators distributed across the deployable structure. Control objectives can be simply to avoid exciting the flexible-body motion, or to actively control these perturbations. Research projects may address one or more of these topics.

Contact mentorAutonomous Cis-Lunar Navigation of a Lagrange Point Orbiting Satellite
Mentor: Mark Brandon Hinga, Directed Energy
Location: Kirtland
Academic Level: Masters, Ph.D.
Autonomous cis- or trans-Lunar spacecraft navigation is critical to mission success as communication to ground stations and access to GPS signals could be lost. However, if the satellite has a camera of sufficient quality, line of sight (unit vector) measurements can be made to known solar system bodies to provide observations which enable autonomous estimation of position and velocity of the spacecraft, that can be telemetered to those interested space based or ground based consumers. An improved Gaussian-Initial Orbit Determination (IOD) algorithm, based on the exact values of the f and g series (free of the 8th order polynomial and range guessing), for spacecraft state estimation, is presented here and exercised in the inertial coordinate frame (2-Body Problem) to provide an initial guess for the Batch IOD that is performed in the Circular Restricted Three Body Problem (CRTBP) reference frame, which ultimately serves to initialize a CRTBP Extended Kalman Filter (EKF) navigator that collects angle only measurements to a known Asteroid 2014 EC (flying by the Earth) to sequentially estimate position and velocity of an observer spacecraft flying in a Halo orbit. With the addition of simulating/expressing the accelerations that would be sensed in the IMU platform frame due to delta velocities caused by either perturbations or corrective guidance maneuvers, this three phase algorithm is able to autonomously track the spacecraft state on its Cis-Lunar journey while observing the motion of the Asteroid.
Contact mentorBeam Control Machine Learning Research
Mentor: Benjamin Shaffer, Directed Energy
Location: Kirtland
Academic Level: Upper-level Undergraduate
Air density variations around and airborne directed energy system distort a beam’s wavefront, resulting in degraded performance after propagation into the far field. Adaptive optics (AO) can be used to correct for these rapidly evolving aero-optical aberrations; however, in some conditions, the inherent latency between measurement and correction in state-of-the-art AO systems results in significantly reduced performance. Predictive AO control methods utilize future state predictions to compensate for rapidly evolving distortions and are promising techniques for mitigating this limitation. Accurate predictions of flow is a challenging problem, and any solution must be sufficiently light-weight to operate at the high bandwidths of an AO system. This research opportunity will involve characterization and development of new methods for producing short-term predictions of high speed flow to improve the performance of beam control systems for applications such as high energy lasers, communications systems, and astronomical seeing.

We are investigating new cold atoms sources that either reduce the size, weight, and power (SWAP) requirements of laser cooled sources or that can cool atoms without lasers. Reducing SWAP is an important considering for making compact devices that can be transitioned from the laboratory into real world applications. Cooling atoms without laser opens the possibility of using atoms that currently cannot be cooled but have properties that are of scientific and/or technical interest.

Help the Air Force Research Laboratory develop new coatings and dopants to impart novel properties, such as electrical conductivity, fluorescence, and enhanced robustness, onto a variety of materials by running computer simulations of molecules and chemical reactions.
The Air Force Research Laboratory Space Vehicles Directorate is charged with developing new capabilities for use on space platforms. One promising approach is to capitalize on the power of chemistry to design novel molecules that inherently have properties of interest. Such an approach is sought as localizing desired properties to individual molecules enables easy deployment as the properties as such molecules can be readily imparted onto spacecraft components by integrating them into composite materials or painting them onto key surfaces. To guide experimental efforts to create such molecules, the undergraduate sought for position will be tasked with running computer simulations to predict synthetic targets for experimentalists to attempt to synthesize and support efforts to interpret experimental results. Anyone with a computer programming background and an interest in developing their skills in computational chemistry is encouraged to apply.

The AST program is developing signals for the next generation SatNav systems, including GPS. These signals will close weaknesses in existing GPS signals, such as provide authentication of civilian signals, rapid acquisition of military signals, improved performance of military signals in jamming situations, etc. Research is ongoing both in the development of new signals (and modification of existing signals) and the development of the receiver algorithms necessary to fully exploit the advanced signal features. An intern project would involve implementing and receiving advanced SatNav data structures in a simulation environment that incorporates interference (jamming and spoofing) elements. Examples include digital signatures to protect against spoofing and data formats optimized to maximize data throughput under challenging conditions.

Decision-Making in the Space Domain
Mentor: Alexander August Soderlund, Space Vehicles
Location: Kirtland
Academic Level: Masters, Ph.D.
The space domain asset population is in the midst of explosive growth, with
the number of space-based assets expected to quintuple by 2030. This is due
to a growing deployment of collaborating small satellites with on-board
sensing and computing technologies. However, as the number of
spacecraft-to-spacecraft interactions is expected to increase, there are
(and will be) limited human-in-the-loop resources available. Thus, these
space systems require autonomous capabilities on-board to carry out a
variety of operations in the space environment. This could include (but is
not limited to) rendezvous and docking, object-of-interest sensing/tracking,
satellite constellation reconfiguration, etc... All of these applications
require decision-making on the part of one or multiple agents to satisfy
mission requirements. This research effort is directed at the inclusion of
autonomy into these decision-making processes. High-level concepts include
information theory, belief fusion, expert reasoning, collaborative tasking,
and the incorporation of modeled and unmodeled uncertainties in the
operating environment. Potential scholars are strongly encouraged to contact
the mentor for more information, as well as to discuss specific research
ideas for the summer.

Academic Level: Masters, Ph.D.
Help the Air Force Research Laboratory develop new coatings and dopants to impart novel properties, such as electrical conductivity, fluorescence, and enhanced robustness, onto a variety of materials.
The Air Force Research Laboratory Space Vehicles Directorate is charged with developing new capabilities for use on space platforms. One promising approach is to capitalize on the power of chemistry to design novel molecules that inherently have properties of interest. Such an approach is sought as localizing desired properties to individual molecules enables easy deployment as the properties as such molecules can be readily imparted onto spacecraft components by integrating them into composite materials or painting them onto key surfaces. To get all of this to work will take a good amount of know-how in a variety of disciplines. Chemistry skills will be needed to design and synthesize molecules anticipated to have the desired properties. Advanced manufacturing skills will be needed to fabricate test coupons and component prototypes. Material science skills will be needed to analyze test samples and evaluate their performance.
Interested in joining this effort and developing your skills in the aforementioned areas? The candidate selected for this program will be tasked with applying their scientific expertise to design new molecules, create new chemical synthesis procedures, and develop new fabrication techniques. Anyone with a desire to build their expertise in these areas is encouraged to apply.

Mentor: Jeff Ganley, Space Vehicles

Academic Level: Lower-level Undergraduate, Upper-level Undergraduate
This project is for Texas State University students involved with USRA's University Consortium Research Opportunity (UCRO). The project will focus on exploring the design, control, and production of geo-polymer type concretes for their potential use in off-world construction. When structures are built off-Earth, the structures are going to require new and unique construction materials that are produced and constructed through non-conventional techniques. A geo-polymer type concrete is perfectly suited for this type of construction as it uses little to no cement, and instead is created through a mixture of the on-site material, which is then chemically activated through a solution. It is important that these materials be well characterized and understood prior to off-world production. Additionally, for off-world construction, conventional Earth based techniques won’t be suitable, therefore the structures will likely have to be built through an additive manufacturing process such as 3D printing. As a Space Scholar in this program, the Scholar will work with AFRL scientists and University of New Mexico faculty to develop and characterize various geo-polymer concretes and test their compatibility/capability with 3D printing at the laboratory scale.

All major military operations rely on space. Space operations are inherently software centric (arguably the one domain where software is most critical). The software world moves entirely too fast for our traditional acquisition paradigm (5+ years timeline from concept to operational use). In order to be relevant in software we need to go from “wild idea” to deploying in operations in 18-24 months. This requires streamlining and automating the process from code level to human level, including integration, security, safety, test, and training. We are seeking to implement a process of Continuous Operational Validation (DevSecDT/OTOps) by bringing people, processes and software technologies together on a two-week development and operations cadence for testing/stress-testing all of the above (people, processes, technologies).

Effects of Uplink Turbulence on Laser Guide Star Wavefront Sensing
Mentor: Jeff Richey, Directed Energy
Location: Kirtland
Academic Level: Masters, Ph.D.
Laser guide star (LGS) adaptive optics (AO) is commonly used on large astronomical telescopes to correct for the distorting effects of atmospheric turbulence and improve imaging performance; however, the output of the LGS laser system is also affected by the atmosphere. The standard solution to this problem has been to limit the diameter of the laser launch telescope to roughly match the coherence length of the turbulence (or the distance over which the atmosphere is approximately homogenous). The Starfire Optical Range (SOR) is interested in extending LGS AO operations into the daytime when the atmospheric turbulence is stronger and thus more likely to negatively impact LGS AO performance. This project will use wave optic simulations to model turbulence effects on laser guide formation and the effect of a misshapen beacon on the performance of the wavefront sensor measuring the atmospheric turbulence. The goal of the project will be to quantify the degradation in AO performance due to an irregular beacon shape, determine the optimal beam size for a given atmospheric turbulence, and to explore methods for improving AO performance in more extreme atmospheric turbulence.

The goal of the research is to investigate the physics of electron field emission under a variety of conditions. Carbon fiber cathodes will be used for the research. First, emission characteristics with pulse width from 100ns to 500ms and DC will be examined. A new cathode test bed will be built for this purpose. Second, different numbers of emitters (1<n<100) will be used to study the turn-on effects of cathodes, and the phenomena will be modeled using a predator-prey relationship. ICEPIC will be used to predict the effects of pulse width on electron field emission, in addition, various numbers of fibers placed on the cathode will be subjected to the same voltage pulse, and ICEPIC will be used to model the cathode geometry, and comparison in terms of the total current obtain and the value of the field enhancement factors will be made with theory and experiment. Lastly, a predator and prey relationship model will be developed to study the physics of emission when large number (1<n<100) of fibers are present on the cathode. During the course of the program, Students will be involved in using ICEPIC to design the geometry of the cathodes, as well as to set up ICEPIC model to study the emission of the cathode under different pulse width. At the end of the internship, students will gain knowledge in the emission physics from a carbon fiber cathode which is highly relevant in future technology.

This project is for Texas State University students involved with USRA's University Consortium Research Opportunity (UCRO). This project will focus on preliminary modeling and investigation into developing and producing an instrumented device that could facilitate the remote assessment of potential austere landing sites. Typically, to determine if an area of land is suitable for an aircraft landing, personnel need to complete a suite of testing on the ground. It is possible that this process could be reduced to a remote assessment through the use of a calibrated and instrumented device that could be dropped from an airplane, take the necessary readings, and transfer via RF the necessary information back to the plane without the use of personnel at the site (i.e. boots on the ground). As a Space Scholar in this program, the Scholar will work with AFRL Scientists to complete a literature search on similar devices and technology that could be adapted or developed to meet this need. Other research components include looking into the instruments, materials, and equipment necessary to develop such a device, as well as producing a 3D model of how the device and its instruments would be assembled and fabricated. If time permits, a preliminary prototype of the device will be assembled and preliminary testing will be accomplished.
Contact mentorEvaluation of quinary GaInAsSbBi mid-wave infrared material and detectors
Mentor: Preston Thomas Webster, Space Vehicles
Location: Kirtland
Academic Level: Masters, Ph.D.
The need for manufacturable high performance mid- to long-wave infrared technologies is growing due to their applications in thermal imaging, gas sensing, and growing potential in noninvasive medical detection/diagnostics. The telecommunications industry has taken advantage of the high manufacturability of near- to short-wave infrared III–V semiconductor materials to support the ever increasing performance requirements of our world’s telecommunications networks. Given the pervasiveness of this industry and its ever-expanding markets, there would be great value in leveraging that same industrial base for mid-wave infrared optoelectronic applications. While the bandgap engineering flexibility of superlattice material systems has furthered our capabilities in the mid-wave infrared, superlattices gain this tunability at the expense of electron and hole wavefunction coupling, which leads lower absorption coefficients and to very low vertical mobility. Given these challenges, a more ideal mid-wave infrared solution would be a bulk III V alloy with sufficient tunability in its bandgap and band edge alignments to form effective heterostructures with other alloy systems at the lattice constant of a large-area commercially available substrate. One potential design space that could enable this technology is an alloy utilizing the heaviest group-V element Bi in a quinary alloy of GaInAsSbBi.
In order to evaluate GaInAsSbBi as a candidate for mid-wave infrared detection, a sufficient quantity of Bi should be incorporated to achieve a mid-wavelength infrared cutoff, and fundamental optoelectronic quality metrics such as the alloy’s minority carrier lifetime need to be investigated. In this project, the minority carrier lifetime of these alloys will be measured and analyzed to gain insight into the performance of GaInAsSbBi infrared detectors.

Experimental limits on supersonically rotating plasmas.
Mentor: Remington Reid, Directed Energy
Location: Kirtland
Academic Level: Ph.D.
When plasmas confined in magnetic mirror traps are subjected to very rapid rotation (10s - 100s km/s) there is a rich interplay between stabilizing centrifugal forces and competing instabilities that limit the rotation rate and degrade the plasma. This project is part of an experimental campaign to understand and overcome observed upper limits on the rotation speed. We create rotating plasmas using pulsed, high voltage electric currents to both ignite the plasmas and drive rotation. Students will have the opportunity to experimentally quantify plasma properties such as rotation rate, turbulent flows, and temperature fluctuations within the rapidly rotating plasmas. The students will gain hands-on experience through the process of designing, calibrating and using their own instruments to collect data as well as processing the data to understand their results.

Mentor: Christopher J Annesley, Space Vehicles
Location: Kirtland
Academic Level: Masters, Ph.D.
The LaSR laboratory is interesting in studying the interactions between photons and either vapor or solid materials through the implementation of experiments and models. One area of interest is in the high temperature spectroscopy of metal-containing species. Metal species and their complexes can potentially have complicated spectroscopy at high temperatures due to the prevalence of low-lying electronic states which can have significant population. By vaporizing metals at different temperature, we will experimentally examine the absorbance/emission of the isolated species as well as any emission arising from reactivity. These experiments compliment modeling efforts toward understanding chemical systems at high temperatures. These modeling efforts include spectroscopic/kinetic modeling of the gas phase species or potentially CFD to examine the vaporization process directly and inform future experiments.
A separate modeling effort involves the modeling of satellite plume species emissions and their life cycle in the space environment. Thruster plume species will have significant interaction with UV photons in the space environment and it is important to both identify and model the kinetics of breakdown pathways. Additionally, identifying and modeling the flux of photons arising from these species upon interactions with the space environment is necessary to understand visual observations. In addition to optical signatures arising from plume species, significant photon flux can arise due to solar reflections arising from the body of the space vehicle in question. Due to the lack of atmosphere in the space environment significant reflections of UV/VUV light may occur, but there is a lack of experimental data on the reflectivity of “real-world” space-relevant materials in these high energy regions.
We will work together to develop a project of mutual interest in one of these research areas.

Contact mentorHigh power fiber amplifiers and coherent beam combination
Mentor: Brian Matthew Anderson, Directed Energy

Academic Level: Masters, Ph.D.
Fiber amplifiers have proven to be a key technology critical to scaling to output powers needed for directed energy applications. Single fiber amplifiers have readily proven scalable to high average powers, and coherent beam combining technology has demonstrated how arrays of fiber amplifiers are readily scaled to specific power levels. Improving capabilities of lasers may include more robust beam combination technology to react to high-speed phase disturbances, and a better understanding of the optical nonlinearities limiting the maximum power from an individual fiber amplifier.
Potential projects include high speed imagery of fiber amplifiers to better understand the temporal dynamics, to modeling and simulation of fiber amplifiers and/or different control algorithms for more robust beam combining systems.
High-Power Fiber Laser/Amplifier Modeling & Simulation
Mentor: Jacob Robert Grosek, Directed Energy
Location: Kirtland
Academic Level: Lower-level Undergraduate, Upper-level Undergraduate
This project will be on modeling high-power fiber lasers/amplifiers. Specifically, the goal is to develop techniques for overcoming nonlinear and thermal effects that inhibit scaling to higher output powers while maintaining good beam quality, and usually narrow linewidth. One method for achieving this goal is through novel fiber designs, which may suppress deleterious processes that occur at high powers in the fibers, but are also complex and challenging to model on a computer. Through this modeling effort various fiber laser/amplifier configurations will be explored in order to optimize the output.
Contact mentorHigh Power mm-wave Interactions with High Temperature Materials
Mentor: Zane Cohick, Directed Energy
Location: Kirtland
Academic Level: Masters, Ph.D.
AFRL is currently pursuing studies of high power mm-wave interactions with materials. One main thrust of this research is to understand the mm-wave, complex permittivity of materials at high temperature. Such an understanding can contribute to multiple applications such as supersonic/hypersonic radomes, mm-wave power beaming, and mm-wave processing of materials (additive manufacturing, sintering, etc.). One goal of this work is to build a predictive model for determining the permittivity of unknown materials up to very high temperatures (>1000℃). Part of building this model could involve traditional regression techniques but neural network approaches have also shown promise. Building a fundamental understanding of loss mechanisms at these temperatures is also desirable - for instance, a material whose loss tangent increases dramatically can give rise to strong thermal gradients and thus material failure. Measurements of conductivity as a function of temperature and frequency may also lead to a better understanding of the motion of ions and defects in materials and thus contribute to the development multi-spectral hypersonic radomes and energy storage technologies (e.g. fuel cells, batteries). This work can be expected to include quasi-optical characterization of complex permittivity up to high temperature (>1000℃) using a variety of methods (Fabry Perot, free-space) with opportunities to develop characterization techniques (e.g. for high temperature, low loss materials and very high permittivity materials).

Mentor: Christopher Charles Wilcox, Directed Energy

Lasers projected from an aircraft need to stay focused as they pass through the air that has been disturbed by that same aircraft. Conversely, light which is being received by the aircraft, e.g. for imaging systems, also needs to be focused after it has passed through the same flow field. In some cases, the turbulent air disturbances are severe enough to severely distort the light, preventing it from properly focusing. The study of these interactions has been described as "aero-optics". AFRL is interested in understanding and predicting aero-optic distortions for a variety of applications. This opportunity involves participation in aero-optic research at AFRL including wind-tunnel experiments and data analysis. Example studies may include investigations of turbulent boundary layers, shear layers or turbulent wakes. In addition to traditional flow measurement sensors (e.g. pressure and velocity), Summer Scholars will have the opportunity to work with flow diagnostic techniques such wavefront sensing and schlieren/shadowgraph techniques.

Academic Level: Lower-level Undergraduate, Upper-level Undergraduate
The LaSR laboratory is interested in studying the gas phase spectroscopy of metal-containing species at combustion-like temperatures. The emission and absorbance of metal complexes can potentially change significantly at high temperatures due to the multitude of low-lying electronic states available to such species. This project centers on experimentally vaporizing a metal species and subsequently measuring the absorbance/emission of the hot vapor in isolation or after reaction with a different species. Mapping out the spectroscopy of metals over a variety of temperatures is essential towards the eventual modeling of applications which produce both high temperature gas-phase metal species and subsequent emission.
Contact mentorInvestigation into the aero-optical component of the jitter for airborne directed energy systems
Mentor: Matthew Robert Kemnetz, Directed Energy
Location: Kirtland
Academic Level: Masters, Ph.D.
One of the major quantities of interest for airborne laser systems is the unsteady variation in the pointing direction of the beam, or jitter. In airborne laser systems, the beam jitter is usually thought of as sourced from two components. The component of the jitter caused by mechanical vibration of the optical table, optical elements, etc. is called mechanical jitter. The component of jitter caused by flow structures on the order of the aperture size is called the aero-optical jitter. In typical experiments, information pertaining to the aero-optical component of the jitter is almost always corrupted by mechanical disturbances and is typically removed from the data. For this reason, much is unknown about the nature of aero-optical jitter disturbances. In the Aero-Effects Laboratory at AFRL we study, among other topics, the aero-optical component of the jitter and its relationship to target tracking performance. This study often involves both experimental work, as well as high fidelity simulations of the aero-optical environment. This project will involve closely guided and mentored research into the aero-optical jitter generated by canonical flows.

IR Transparent Conductors
Mentor: John Bryan Plumley, Space Vehicles
Location: Kirtland
Academic Level: Masters, Ph.D.
The Space Vehicles Directorate is actively pursuing ways to fabricate an IR transparent conductor to be used in thermal space applications. One approach is to apply a thin conductive film to an IR transparent substrate, but the issues that arise are thin film adhesion and too narrow of an IR transmission window from either the conductive film or the substrate. In addition, IR transparent substrates generally have too low of a melting point to withstand high temperature annealing of the conductive thin film. Alternatively, what would be of interest from the applicant is the development of an intrinsically conductive IR transparent polymer that could be efficiently processed in the lab and characterized and tested as an electrode for electroplating metal.

By using machine learning methods, we hope to expedite the process of generating realistic event based data without the need for developing expensive ab initio pixel circuit models. The project will begin with the collection of event based data using multiple sensors in the lab or in the field as needed. We will then use these data sets to train machine learning algorithms and subsequently output data that is representative of the original data. Finally asses the performance of this simulated data against the original.

The physics occurring at the emission sites of high performance electrospray systems is still ripe for experimental and theoretical exploration designed to improve our understanding of the operation of the devices.
In this project, the selected student will either undertake experimental or theoretical approaches to further the understanding of the plume of ions emitted from either (or both) a capillary or externally wetted emitter. Theoretical methods, if the student’s primary interest, might include the use of quantum mechanical and molecular dynamics approaches to the prediction of emitted ion clusters, the lifetime of the clusters, prediction of the plume shape and other observables, modelling in support of experimental data or other related work.
Students focused primarily on experimental investigations will utilize mass spectrometry, current-sensing and mass-sensing tools to examine the plume generated from various different propellants or emitter types at relevant volumetric flow rates. Analysis of the experimental measurements will yield insights into trends among the different propellants and improve understanding of the microphysics occurring post-emission in a laboratory thruster.

We work with various satellite processing architectures and try to fit specific algorithms to each one. Going back to image processing, their is an idea of processing on-board the satellite while in space, the problem is power limitations and the harsh space environment. Specifically the power requirements and the radiation effects on hardware. that is why bio-inspired hardware is of interest to our group, as they complete highly parallelized processing at a fraction of the cost of modern processors. We will explore many aspects of these systems and how well they can perform, which could broaden out into spiking neural networks or different online training methods. On another route, neural network models could be improved for space related imagery or optimized by being combined with different image processing solutions/algorithms, pre-processing methods, or etc.

This project seeks to develop improved methods for spacecraft guidance, navigation, and control (GNC) through improved understanding of the spacecraft nonlinear dynamics. Spacecraft translational motion is dominated by orbital dynamics, and the control is often constrained by a limited fuel supply. Therefore, translational GNC methods generally must be designed to work with these dynamics instead of fighting them. Spacecraft attitude motion is governed by the particular structure of rotational dynamics, and robust performance of attitude GNC methods depends on careful adherence to this structure. Additionally, spacecraft operations are subject to significant nonlinear control-estimation interactions, an example being the lack of observability of control-free relative motion in close proximity when using angles-only measurements. Research projects may address one or more of these topics.

Novel Cooling Films
Mentor: John Bryan Plumley, Space Vehicles
Location: Kirtland
Academic Level: High School
The Space Vehicles Directorate is actively pursuing ways to developing conductive, robust passive cooling surfaces. We've developed a non-conductive micro structure passive cooling material that can be applied to any surface, however because of the highly brittle and porous nature of the cooling structure it has proven ineffective to merely deposit a conductive thin film material over the structure. What needs to be done instead is to infiltrate the structure with a liquid precursor that can be hardened into a polymer or silica matrix that will result in a robust and smooth microstructure which can then be made to have a conductive surface. The applicant will learn to process and characterize cooling films as well as synthesize sol gels for microstructure hardening. The applicant will gain experience in conducting literature search, working in a chemistry lab, spray coating, and microstructure modification.

Contact mentorNumerically Calculating a Ballistic Missile’s Null Range Axis for a Desired Impulse
Mentor: Mark Brandon Hinga, Directed Energy
Location: Kirtland
Academic Level: Ph.D.
Using the theory of linearized perturbation techniques in concert with a two point boundary value shooting method, it is possible to refine the trajectory of a ballistic spacecraft by applying an optimum impulsive velocity maneuver at some time t to alter and improve its position at final time tf . This same theory may also be used to solve for the inertial direction (out of plane if desired) along which a small desired velocity impulse may be applied during ballistic flight of a missile at some time t, that does not alter the warhead’s intended target position (ground impact) at arrival time. This paper introduces an approach to calculate not only this inertial direction, known as the Null Range Axis (NRA), but also the particular direction that corresponds to an arbitrary or desired impulsive magnitude. Included in this investigation is a J2 gravity field for a rotating Earth, which requires that a plane change be incorporated into the computation of a missile’s NRA direction at time t. Earth atmosphere is ignored. Ultimately it is desired to compute this inertial direction in "real time", not prior to flight. Simple notional kinematic spinning reentry vehicle pointing (circular coning) will be developed if time allows.

However, the increasing need for real-time sensor and autonomous processing, coupled with limited communication bandwidth with ground stations, is increasing on-orbit computing demands for next-generation space missions.

Results will help determine how to best optimize architectures for various applications and which architectures are best suited for which missions, and can be used to guide future DoD investment decisions.

Optical Characterization of Spacecraft Materials Damaged in a Simulated GEO Environment
Mentor: Ryan Hoffmann, Space Vehicles
Location: Kirtland
Academic Level: Masters, Ph.D.
The goal of this study is to characterize how the optical properties of commonly used spacecraft materials change due to exposure to energetic particles. In space, energetic particles break bonds within a material such as polyimide (Kapton®), often forming free radicals. These radicals can then reform the original bond, or they can form new bonds, creating a new material. Understanding the chemical mechanisms for bond breaking and forming processes individually will allow for development of a model to predict the material’s chemical composition as a function of environmental exposure and time. We will simultaneously characterize the optical properties and chemistry of the materials, and develop understanding and correlations between material chemistry and optical signatures.

Mentor: Ryan Hoffmann, Space Vehicles

One way to detect and identify spacecraft is to gather the sunlight reflected from the spacecraft as it orbits overhead. These data contain a huge amount of information about the position, composition and intent of the spacecraft that is difficult to obtain in any other way. However, these light curves are dependent on the spacecraft surface materials and they are know to change in response to space weather exposure. So to make the most use of these types of data, we must understand how the reflectivity of spacecraft materials change.
During this project you will interface with the spacecraft observing community and lab based scientist to quantify the degree of optical changes to common spacecraft materials under simulated GEO exposure in the lab. These data will then be applied to observations of spacecraft in modeling software to recreate the complex light curve of real space objects.

Mentor: Kyle William Martin, Space Vehicles

Academic Level: Lower-level Undergraduate, Upper-level Undergraduate
Phase-stabilized optical frequency combs were first developed as a means for measuring the frequency of an optical clock (i.e. to 'count' optical frequencies). The wide spectral coverage and femtosecond-level timing precision offered by a frequency comb makes it an attractive tool for many advanced technologies. Compact and robust frequency comb sources are now available as all-polarization-maintaining fiber lasers, which have been shown to operate outside the metrology laboratory. Moreover, micro-resonator combs offer unique promise in their wide mode-spacing and small footprint. We are developing frequency comb sources suitable for terrestrial and space applications; digital control algorithms for frequency comb stabilization; and applications that exploit the attractive features of the comb related to free-space optical time transfer, optical communications, and coherent spectroscopy.

Contact mentorOptical Signatures of Ion-Neutral Collisions
Mentor: Benjamin Douglas Prince, Space Vehicles
Location: Kirtland
Academic Level: Upper-level Undergraduate
The normal operation of electric propulsion devices results in the generation of atomic and molecular ions of various charge, often with significant velocities. These expelled ions can collide with other atomic and molecular components (e.g. Earth's atmosphere, un-ionized propellant) and impart a significant amount of internal energy into the collision partners. This internal energy can be rotational, vibrational and/or electronic and often leads to emission of photons at specific wavelengths. These specific wavelengths occur because of the unique energy levels of the collision partners. While the thruster environment can be relatively complicated, these collisions can be generated in the laboratory under controlled conditions such that quantitative determination of the populations in the various energy levels can be determined. These populations can lead to specific optical signatures that can be used for thruster diagnostics and safety-of-flight purposes.
In this task, the interested student will perform modelling and simulation of the collision systems using custom research and development codes developed in previous years to predict optical signatures resulting from the collisions. The student will compare the theoretical results to experimental measurements and assess the predictive quality of the models. This effort will also be paired to an experimental effort of the same name in the Space Scholars Program.

We study a broad range of plasma chemistry including electron attachment, ion-molecule reactions, dissociative recombination, and mutual neutralization. We specialize in studying difficult species, radicals, and extended temperature ranges. Several fast flow plasma reaction apparatuses are used. The ion-molecule temperature range is 90-1800 K, while for the other plasma processes temperatures up to 1400 K can be studied. Recent successes include measuring the only product distributions for mutual neutralization, electron attachment to fluorocarbon radicals, and the discovery that electrons catalyze mutual neutralization. A recent upgrade has allowed for studies of radicals with electrosprayed ions, which is important for solar fuels research.
The data support a wide variety of AF/DoD applications including the natural ionosphere, hypersonic vehicles, plasmas assisted combustion, high power lasers, conversion of gaseous to liquid fuels, trace gas detection, high energy density materials, and other catalytic processes.

Controlled magnetic fields are critical to the operation of confined atom interferometers, and associated inertial sensors. This project involves further developing in-house capabilities for laser etching so-called 'atom chips'. We use inexpensive DBC substrates: aluminum nitride with a layer of copper bonded to each face. By laser cutting specific wire shapes into the copper, we can create well-controlled magnetic fields simply by varying the applied currents. These chips already enable a variety of experiments involving ultracold atoms, and were used to create a Bose-Einstein condensate. Our goal is to progress to more advanced structures and processes, carefully characterize the laser mill cuts, and reduce the need for post-processing due to trace defects.

Contact mentorPropagation of solar energetic particles in space
Mentor: Stephen Kahler, Space Vehicles
Location: Kirtland
Academic Level: Lower-level Undergraduate, Upper-level Undergraduate
Big solar eruptive events often result in the production of highly energetic particles that propagate from the Sun out to the Earth and beyond. In some cases these solar energetic particles (SEPs) reach GeV energies, cause serious communications and spacecraft problems, and can be detected with ground based detectors. The general understanding is that SEPs are accelerated in shock waves in the solar corona that are driven by mass ejections in the eruptive events. The SEPs propagate along magnetic field lines away from the Sun and spread throughout interplanetary space. Our work attempts to understand the origin of the SEPs - what seed particles are accelerated, and when and where in the eruptive events? What eruptions or solar conditions are favorable or unfavorable for SEP production? We use data sets of spacecraft in situ observations of SEPs and space and groun-based optical, radio, EUV, and X-ray observations of solar eruptions to characterize and understand SEP production. Because of the great diversity of SEP events, the work is often statistical in nature, with analysis of properties of many observed SEP events.

Mentor: Julie Victoria Logan, Space Vehicles

The AF and DOD as a whole would like to increase the operating temperature of VIS-LWIR detectors. The goal of this topic is to better understand the fundamental mechanisms that drive the overall dark current in III-V based barrier architecture detectors such as, but not limited to, nBn, pBp, complementary barriers, etc. By developing an in-depth understanding of the mechanisms that limit performance it is anticipated that improved barrier architecture detector designs will result in detectors that can be operated at higher temperatures resulting in an eliminated or reduced need for cryocoolers. Summer research thrusts can be in several areas including: dark current, QE, and noise measurements. These detectors will ultimately be utilized in a space environment so there is keen interest in understanding their performance when subjected to ionizing radiation. Deliverables from this research will ultimately dictate the path forward in future detector growth-characterization campaigns. OPSEC Approval AFRL-2022-3887

Satellite Deployable Structures Research
Mentor: Niccoli Navarro Scalice, Space Vehicles
Location: Kirtland
Academic Level: Masters, Ph.D.
The new generation of deployable space structures utilize thin, high-strain composite components in place of traditional metallic mechanisms. These high-strain composites offer many benefits including the ability to stow into much smaller volumes, being much lighter weight, and having near-zero coefficients of thermal expansion. The challenges of designing structural systems utilizing these composites include their integration into larger satellite systems. Using holistic design approaches that consider the effects of a subsystem on the larger system’s performance, and the ability to balance all strengths and weaknesses of a given design is vital.
With guidance, students will investigate novel deployable structure designs and integration concepts to maximize deployment reliability, stowage efficiency, and performance of deployable structures for future Air Force and DoD satellites. Students will have access to CAD modeling software (SolidWorks), Computational and FEM software (MatLab, ANSYS), and AFRL’s state-of-the-art fabrication facilities.

Satellite Rendezvous & Proximity Operations Characterization
Mentor: Zachary Kahl Funke, Directed Energy
Location: AMOS
Academic Level: Ph.D.
The Air Force Maui Optical & Supercomputing Site is researching the application of new algorithms and techniques to apply to a coordinated network of space surveillance sensors for the purpose of observing and characterizing close encounters between satellites in an effective and autonomous manner. While accidental orbital conjunctions occur from time to time, this project is focused on intentional activity that may be considered interesting or possibly threatening. There are inherent challenges with observing and characterizing these rendezvous and proximity operations (RPO), such as inability to resolve distinct objects at close separations, properly keeping track of which object is which using relatively sparse observations, accurate knowledge of objects' trajectories when small and frequent maneuvers are taking place, and timely indication that one object appears to be planning or initiating RPO with another object.
It is believed that these challenges would be best addressed by exploring new techniques and algorithms that enable a sensor network to do the following things:
1. More quickly and accurately determine an object's orbit, i.e. position and velocity, for the purposes of characterizing RPO activity
2. More robustly handle objects which maneuver frequently and slightly, and accurately characterize those maneuvers
3. More robustly identify and associate objects, for example by using a logical reduction of raw optical imagery which associates objects based on their brightness or other characteristics in addition to their orbital motion
4. Autonomously task telescopes in such a way as to balance the information gain of characterizing an ongoing RPO situation with other competing requirements on those telescopes, such as custody of objects in different parts of the sky

Contact mentorSpaceborn Auto-Navigation via Implementation of Optical Planetary Angle-Only Measurements
Mentor: Mark Brandon Hinga, Directed Energy
Location: Kirtland
Academic Level: Lower-level Undergraduate, Upper-level Undergraduate
Autonomous spacecraft navigation is critical to mission success as communication to ground stations and access to GPS signals could be lost. However, if the satellite has a camera of sufficient quality, line of sight (unit vector) measurements can be made to known planetary bodies and provide observations enabling estimation of position and velocity of the spacecraft. Because the well-known solar system bodies might also be near coplanar with the spacecraft's orbit, advanced orbit determination algorithms may be needed to mitigate the expected problem of the relative co-planarity between both the spacecraft's and the visible planet's orbit.
This investigation has two goals. The first is to determine the minimum quality of line of sight navigation measurements to target planet bodies necessary for successful insertion into destination orbit. The second is to design an improved initial orbit determination (IOD) algorithm to mitigate the anticipated co-planar (singularity causing) problem without the need of an a priori assumption of either orbit class or any specific orbital regime of the spacecraft. What is novel in this proposed research is its consideration of a least squares batch initial state estimator that implements the linearized perturbation technique (fixed final time guidance) in conjunction with a Lambert solver and a stabilized Gaussian-IOD method. This latter method might be expected to handle the co-planar singularity condition as low as 0.1 deg. and aid in the initialization of an EKF that can maintain track of the unique stabilized solution of the host spacecraft. This stabilized batch algorithm might also allow for accurate initial orbit estimation of the spacecraft using a limited set of (as few as six might be possible) planetary measurements and is built upon a system of co-planar observed singularity conditions that form the normal equations of the exact values of the f and g series least squares solution.
This research will consider errors in the precise centering of the line of sight unit vector to the center mass of a measured target planet. The effect of light travel time and light aberration will be taken into account due to the large distances between the spacecraft and an observed planetary body.

When magnetized plasmas rotate at very high velocity (10s - 100s km/s) there is a rich interplay between stabilizing centrifugal forces and a diverse field of instabilities that can limit the rotation speed and degrade the plasma.

Current imaging, wavefront-sensing, and adaptive-optics solutions are inadequate when in the presence of distributed-volume atmospheric aberrations and extended objects (aka the "deep-turbulence problem"). This shortcoming requires that we innovate towards a new solution. In leveraging a recent journal-article publication [https://doi.org/10.1364/JOSAA.36.000A20], this research opportunity will develop imaging, wavefront-sensing, and adaptive-optics approaches that sense and correct for the disturbances found all along the laser-propagation path. Overall, this volumetric solution will enable advanced remote-sensing and directed-energy functions at extended standoffs.

Mentor: Spencer E Olson, Space Vehicles
Location: Kirtland
Academic Level: Upper-level Undergraduate
This opportunity is designed for students from Georgia Institute of Technology participating in University Consortium Research Opportunity (UCRO) research.
The subject of our research is precision timing and inertial sensing enabled by advances in atomic physics and photonics. One of our major efforts pursues the development of robust, miniaturized optical clocks including optical frequency combs. These portable clocks will provide a cost-effective replacement for the atomic clocks aboard the global positioning satellite constellation and will enable new applications of precision timing such as free-space optical time transfer. Another major effort uses atom-chip devices to develop confined atom interferometry, which offers the possibility to dramatically increase the interrogation time of atom-based inertial sensing devices. We use a rapid prototyping technique for atom chips that allows us to quickly customize and live-test atom chip structures. We are also exploring techniques for developing compact atomic devices, including large-diameter hollow-core fiber guiding, integrated atom-chip transport, and on-chip micro-optical cavity integration.

University Consortium Research Opportunity (UCRO) - The University of Texas at El Paso - Software Design for Hyperspectral Sensor Control
Mentor: Cody L Shaw, Directed Energy
Location: AMOS
Academic Level: Masters, Ph.D.
AFRL's spectroscopy portfolio has multiple hyperspectral sensors that require innovative software design for control and data collection and processing. These sensors include spectrographs, slitless spectrographs, and polarimeters. The portfolio seeks to leverage the data from these sensors for problems within the space domain, to include object detection, classification, and tracking, among others. The portfolio will test and evaluate traditional data processing techniques alongside more modern AI/ML
techniques. However, the data can only be collected and analyzed with sophisticated software design for sensor control. The next stage in this work is to 1) design and build software to control numerous hyperspectral sensors, 2) evaluate system performance, 3) assess design and control options for maximizing detection and identification goals, and 4) present the work in a final presentation at the end of the 12-week internship.
University Consortium Research Opportunity (UCRO) – University of Akron – Advanced Guidance and Control Law Development
Mentor: Alex Sizemore, Space Vehicles
Location: Kirtland
Academic Level: Upper-level Undergraduate
This opportunity is designed for The University of Akron students involved with USRA’s University Consortium Research Opportunity (UCRO). Due to the high cost of space systems, the ability to inspect, service, and repair/refuel these systems on-orbit is highly desirable. Such missions require precise control of spacecraft motion to ensure mission objectives are met (e.g., imaging parameters, relative velocity constraints for docking, etc.), which is dependent on the closed-loop guidance algorithms used to ensure the vehicle completed the required mission within the defined constraints. This topic seeks to develop improved guidance algorithms that provide improved robustness and performance in the face of systemic uncertainties (e.g., modeling errors), are adaptive to such errors to enable performance in spite of errors, provide solutions for mission assurance and mission safety (e.g., fail-safe qualities), enable efficient use of spacecraft resources (fuel, power, etc.), and are reconfigurable based on shifting mission priorities.

Mentor: Alex Sizemore, Space Vehicles
Location: Kirtland
Academic Level: Masters, Ph.D.
This opportunity is designed for The University of Akron students involved with USRA’s University Consortium Research Opportunity (UCRO). Optimization techniques are difficult to implement in real-time on spacecraft due to many factors, including but not limited to (a) computational burden, (b) use of memory, and (c) confidence in obtaining a solution. This project will focus on exploring and developing a wide range of optimization methods that mitigate the challenges above. The algorithms developed will then be benchmarked against others for different scenarios (in simulation & robotic testbed implementation).

Mentor: Alex Sizemore, Space Vehicles
Location: Kirtland
Academic Level: Upper-level Undergraduate
This opportunity is designed for University of Michigan students involved with USRA’s University Consortium Research Opportunity (UCRO). Description: Guidance, Navigation, and Control (GN&C) is only one part of a spacecraft architecture. At the next level, the spacecraft must be able to make its own decisions based upon information it has. The decision making process is complex, where there are several modes in which different control and estimation schemes are employed. Examples include momentum management, fault ID and mitigation, or rendezvous of spacecraft. Students in this project will focus on exploring and developing these decision making problems while working towards creating method to make these decisions efficiently.

Mentor: Maxwell David Gregoire, Space Vehicles
Location: Kirtland
Academic Level: Lower-level Undergraduate, Upper-level Undergraduate
This opportunity is designed for students from the University of New Mexico participating in University Consortium Research Opportunity (UCRO) research.
We are researching ways to use laser-levitated nanoparticles to measure acceleration. Our ultimate goal is to create a small, portable accelerometer rivaling the precision of state-of-the-art systems to be used on satellites, aircraft, and other military vehicles. By levitating nanoparticles with a focused laser beam forming what is known as “optical tweezers,” we can explore physics at the boundary between classical and quantum mechanics and make extremely precise measurements of forces. A scholar on this project may help develop methods of launching and catching nanoparticles in ultra-high vacuum, engineer ways to isolate acoustic noise from measurements, write computer programs to manage or model data acquisition, create and modify laser and optical systems, or explore the theory of interactions between light and matter in optical cavities.
University Nanosatellite Program
Mentor: Jesse Olson, Space Vehicles
Location: Kirtland
Academic Level: Lower-level Undergraduate, Upper-level Undergraduate
The University Nanosatellite Program (UNP) was founded in 1999 to foster satellite development expertise in young engineers and to generate new small satellite technologies on small satellite platforms. UNP works with various universities across the country to guide students in the end-to-end design and fabrication of small satellites. UNP typically selects 1 to 5 students to participate in the AFRL Scholars program to assist in this objective. Selected candidates will be required to assist in the analysis, test or documentation for the current nanosatellites preparing for launch. Often times this involves hands-on activities with the satellite. The candidates will also participate in program activities including spacecraft testing, troubleshooting, requirements verification, and providing technical expertise to other university participants within the program. Scholars may have the opportunity to accompany the UNP Office to official small satellite events during the summer. Scholars will have the opportunity to gain and swap systems engineering experience and expertise with other students and professionals in various small satellite lab programs across the US.
