<p>The goal of this project is to develop a specialized GPS sensor prototype to enable high-performance GPS navigation for future cis-lunar and lunar missions. This sensor will be based on the NavCube, the next-generation version of the record-setting high-altitude MMS-Navigator GPS receiver. The proposed GPS sensor will target future lunar missions including robotic and human spaceflight applications. The proposed lunar GPS sensor will combine enhanced GPS signal processing and use the Goddard Enhanced Onboard Navigation System (GEONS) flight software to provide position and timing information for future lunar missions and cis-lunar missions, and will benefit crewed and un-crewed science and exploration missions.</p>

NASA's exploration and scientific missions will produce terabytes of information. As NASA enters a new phase of space exploration, managing large amounts of scientific and operational data will become even more challenging. Robots conducting planetary exploration will produce data for selection and preparation of exploration sites. Robots and space probes will collect scientific data to improve understanding of the solar system. Satellites in low Earth orbit will collect data for monitoring changes in the Earth's atmosphere and surface environment. Key challenges for all these missions are understanding and summarizing what data have been collected and using this knowledge to improve data access. TRACLabs and CMU propose to develop context aware image manipulation software for managing data collected remotely during NASA missions. This software will filter and search large image archives using the temporal and spatial characteristics of images, and the robotic, instrument, and environmental conditions when images were taken. It also will implement techniques for finding which images show a terrain feature specified by the user. In Phase II we will implement this software and evaluate its effectiveness for NASA missions. At the end of Phase II, context aware image manipulation software at TRL 5-6 will be delivered to NASA.

This dataset provides information on budget appropriations for each fiscal year starting in FY 2010. The data provides granular detail down to the budget organizational unit and and object class for the department request, the Governor's recommendation, the enacted budget, and the adopted budget. The state fiscal year runs from July 1 to the following June 30 and is numbered for the calendar year in which it ends. The State of Iowa operates on a modified accrual basis which provides that encumbrances on June 30 must be paid within 60 days after year end. The Legislature may enact exceptions to this statute and usually do so for capital items which may run for several years. Department names and budget units for FY 2010 - 2015 are based on names used in FY 2016.

Assistive Free-Flyers (AFFs) are flying robots designed to share the living space with human astronauts in orbit. These robots have shown the potential to assist astronauts with tasks such as surveillance, inspection, and mapping. However, AFFs are currently designed without manipulation capabilities, and can thus be deployed mainly for sensing and observation. In this project, we aim to provide AFFs with the capability to physically interact with the environment through manipulation. We plan to equip AFFs with compact yet dexterous robotic arms and hands developed in this project, along with the planning and control methods needed to operate them. We aim to demonstrate new capabilities on tasks such as object acquisition and transport, part insertion and extraction, button or lever operation, docking and perching. We believe these abilities will greatly increase AFFs' reach, literally and figuratively.

Simultaneous Localization and Mapping (SLAM) in robotics, is when a robot constructions a set of geometrical features of its environment (mapping) and uses sensing to estimate where it is relative to those features (localization). For example, the robot learns where walls are in a building and then can learn how to navigate between a start and goal without hitting them. SLAM sensors have been lidar (3D laser sensor like on Kinect) or bi/tri-ocular (two or three image cameras). This proposal suggests the use of a monocular sensor which is just a single camera that records images without any 3D data. Using the accelerometer and gyroscope along with the camera in a smartphone, some 3D information can be recovered. By using computer vision techniques, the sets of features are found in a sequence of camera frames. From the accelerometer and gyroscope data these are then fitted to statistical estimates of where these features are in the 3D environment. Then using sensor fusion techniques the data is compiled and then traditional SLAM algorithms are used. This would allow SLAM within lower weight, cost, and power sensors. The Smart SPHERES are a direct application of monocular SLAM that are being used to research robotic autonomy. Robotic navigation autonomy is important because it enables robots to aid astronauts with their numerous tasks around the space station with their highly limited time. Second, the technology extends to exploration probes such as the mars rovers which have too much of a communication time delay to be operated purely by teleoporation.

The objective of my proposal is to determine the stability of a spacecraft when in the vicinity of an asteroid. Orbiting an asteroid is a difficult task. The unique shapes in which asteroids are formed cause the gravity around them to be non-uniform. This causes perturbations in the movement of a spacecraft around an asteroid. Solar radiation pressure can also alter the orbit of a spacecraft around an asteroid. With multiple perturbations on a spacecraft, orbiting an asteroid can become unstable over time. This instability could lead to the spacecraft escaping from the body or crashing into the asteroid. By determining an algorithm that can define the stability of a spacecraft around an asteroid, safe and stable orbits can be found for an operational spacecraft. In order to achieve a greater understanding of the stability of a spacecraft in the vicinity of an asteroid, the dynamics of the spacecraft around the asteroid must be well understood. All perturbing forces that will act on a spacecraft orbiting an asteroid must be accurately modeled. This includes mathematical modeling of the gravity around the asteroid due to its non-spherical shape, third-body dynamics from the sun, and solar radiation pressure. Rotation of the spacecraft and asteroid will also be part of accurately modeling the dynamics of this system. The largest portion of the research will be focused on determining what the proper definition of stability is for the spacecraft. Stability of a system can be defined in various ways using multiple stability analysis methods. Because these differing methods often result in subtle differences that have significant consequences, the determination of stability for a spacecraft mission can be difficult to find using mathematical definitions that apply to practical needs of the mission. Therefore finding a meaningful mathematical definition for stability that can be applied to an operation mission will be the core of my research. Lyapunov stability will used as a preliminary tool to give insight into more complex methods of determining stability. This includes the stability methods such as Lyapunov characteristic exponents, FLI, and MEGNO. For future missions to asteroids this allows the spacecraft to orbit naturally without as many correctional maneuvers. Also, understanding the stability of a spacecraft around an asteroid will give future missions more confidence in opting to orbit in close proximity of the asteroid, which will allow for more science to be obtained. Gaining knowledge on the behavior of a spacecraft around an asteroid will help define go to stable orbits that are dependable for the spacecraft to stay in for long periods of time. By better understanding the dynamics and stability of spacecraft motion around an asteroid, a spacecraft will be able to achieve better understanding of the asteroids size, shape, rotation, gravity field, and mass. Therefore it encourages a relationship where a better understanding of the dynamics of the spacecraft causes more science to be found; and with better science comes more refined models that improve the dynamics of the orbiting spacecraft. This information can be used for both scientific human missions and resource extraction missions to asteroids. NASA plans on landing humans on an asteroid with the next generation of crewed space flight vehicles. With human life on the line, knowledge of how the crew transport vehicle will behave orbiting the asteroid needs to be well known.
