From the program website:
Micro-g Neutral Buoyancy Experiment Design Teams (Micro-g NExT) program challenges undergraduate students to design build, and test a tool or device that addresses an authentic, current space exploration problem. The overall experience includes hands-on engineering design, test operations, and educational/public outreach. Test operations are conducted in the simulated microgravity environment of the NASA Johnson Space Center Neutral Buoyancy Laboratory (NBL).
We chose the Rock Chip Sampling Device for Microgravity Challenge. The name for our device is the Rock Extraction Chipping Container or RECC for short. RECC by REKK.
