This focus is essential for developing both the technical minds and creativity of the next generation. The education industry cannot push STEM activities to the next level without the help of outside partners who have industry insight and experience. This is why Virginia Commercial Space Flight Authority (Virginia Space), Twiggs Space Laboratory, LLC (TSL), Northrop Grumman (NG), NASA Wallops Flight Facility (WFF), and Near Space Launch Corp (NSL) have all partnered together to develop the Virginia Space ThinSat Program. With our primary focus being on STEM outreach, the program has developed a new way to bridge the gap between satellite development and the education industry. By utilizing this platform, we have already seen development of beneficial research potential from numerous institutions that shows the promise of a bright future for the Virginia Space ThinSat Program and Extreme Low Earth Orbit (ELEO) research. PROGRAM OVERVIEW National Aeronautics and Space Administration STEM advancement is on the forefront of (NASA). The ThinSat Program was developed with the most technical educator’s minds as the next generation vision to allow students to design and build their own of students are being molded to become the future payloads in order to be challenged with an engineering technical minds of the world.

  • Modelling a C-Band Space Surveillance Radar Using Systems Tool Kit
    UNCLASSIFIED Modelling a C-Band Space Surveillance Radar using Systems Tool Kit Mark Graham and Stephen Bocquet Joint Operations Division Defence Science and Technology Organisation DSTO-TN-1164 ABSTRACT A model of the AN/FPQ-14 C-Band radar was developed using Analytical Graphics, Inc. (AGI) STK software to support studies investigating the operational performance of the system for surveillance of Space and the contribution it could make to the Space situational awareness mission. STK scenarios were developed to assess the detection performance of the radar model against a satellite target with a given orbital altitude, radar cross section (RCS) and minimum signal to noise ratio (SNR) required for detection. These results were compared to those obtained by evaluating the radar range equation. A comparison was also made on the effects of refraction using the effective radius method and International Telecommincations Union (ITU) model.

The 2017 study deals with the requirements and preliminary design aspects of a software simulator of a space elevator system. The goals of the study are to identify the most important functions of such a simulator, derive from these the requirements of the software to be developed and outline its major design characteristics.

  • Visual Interactive Trajectory Design
    AAS 19-449 VISUAL INTERACTIVE TRAJECTORY DESIGN Ravishankar Mathur* A method of altering trajectories via visual “grab-and-drag” gestures with imme- diate graphical response, called Visual Interactive Trajectory Design (VITD), is presented. The various components of VITD are defined (e.g. draggable objects), and how they affect the trajectory is discussed. An implementation of VITD is demonstrated that uses the General Mission Analysis Tool (GMAT) to propagate trajectories, and visualizes them in realtime using the OpenFrames 3D visualiza- tion API. Examples of using VITD are shown, including finding a lunar free-re- turn trajectory by visually rotating the trajectory’s initial velocity vector. The ben- efits of VITD are explored, including for teaching, exploring the design space, and generating initial-guess trajectories for optimization. INTRODUCTION As a result of advances in astrodynamics applications over the past two decades, high-fidelity visualizations are no longer considered a novelty or optional component of mission design and analysis. Widely-used commercial and government-developed tools such as Systems Tool Kit (STK)1, Copernicus2, and the General Mission Analysis Tool (GMAT)3 all contain 3D visualiza- tions that provide critical information far above and beyond what text-based data or static plots can achieve. These visualizations have become an essential part of effective trajectory design and op- timization, so much so that they are used to affect design decisions and not merely for the sake of output pictures and presentations. For example, design for the NASA OSIRIS-REx mission’s Touch-and-Go (TAG) trajectory was performed in part with STK4, and 3D visualizations played an important role in validation of that trajectory.

  • Blockchain Application Within a Multi-Sensor Satellite Architecture
    Blockchain application within a multi-sensor satellite architecture Rohit Mital SGT KBRwyle Jack de La Beaujardiere U. of Maryland, College Park Rohan Mital U. of Colorado, Colorado Springs Marge Cole NASA ESTO and SGT KBRwyle Dr. Charles Norton NASA Headquarters ABSTRACT With the thrust towards multi-sensor satellite architectures for earth and space exploration, such as constellations and swarms, new technologies are required to enable the transition to this future capability. One of the areas of interest is establishing secure, efficient and prioritized data and command communication pathways among ground and space-based sources for such systems. This paper presents early research results on the potential role, capabilities and value of blockchain usage within constellation and swarm satellite architectures. It demonstrates the use of blockchain’s smart contract and distributed ledger capabilities for secure and prioritized multi-sensor satellite collaborative data exchanges, as well as the logging and tracking of command and control events. Adapting and utilizing this emerging technology will aid in addressing technology gaps expected from future constellation flight architectures, such as managing collective computational operations (correlation), dynamic and autonomous observation planning, time-critical events, and provenance tied to ground and space-based autonomous operations and control recordkeeping. In this scenario blockchain is applied in encrypted command transmittal to multiple, yet specific, entities enabling acknowledgement transmittals, performance scalability, and automatic event-based triggering. INTRODUCTION The blockchain testbed project was started with the intent to research and experiment with blockchain technology and to assess whether this technology could be leveraged as an approach for some general use cases: secure and prioritized multi-sensor satellite collaborative data exchanges and the logging and tracking of command and control events.
