Astrobee is a free-flying, 1'x1'x1' cuboid robot that is planned to be onboard the International Space Station (ISS) by February 2019. Astrobee will be the successor of the current ISS free-flyer, SPHERES. Free-flying robots possess a range of potential. They can facilitate work for astronauts aboard the ISS by performing rudimentary tasks and housekeeping (e.g., record-keeping, sensor analysis, etc.) efficiently. Free-flyers also act as innovative testbeds for guest scientists to perform zero-gravity control theory research. In recent years, SPHERES has hosted annual Zero Robotics (ZR) programming competitions in collaboration with MIT, challenging middle and high school students to write code …

NASA’s Fiber Optic Strain Sensing (FOSS) system can gather and store up to 1,536,000 bytes (1.46 megabytes) per second. Since the FOSS system typically acquires hours—or even days—of data, the system can gather hundreds of gigabytes of data for a given test event. To store such large quantities of data more effectively, NASA is modifying a Lempel-Ziv-Oberhumer (LZO) lossless data compression program to compress data as it is being acquired in real time. After proving that the algorithm is capable of compressing the data from the FOSS system, the LZO program will be modified and incorporated into the FOSS system. …
