Purpose of the flight and payload description

BOBCAT is the acronym of Balloon-Borne Cryogenic Telescope Testbed, a technology demonstration to develop advanced instrumentation for astrophysical observations at far-infrared wavelengths, carried out at NASA's Goddard Space Flight Center (GSFC).

Main objective of the project is to develop cryogenic techniques as an enabling technology to improve far-IR sensitivity by a factor of 100,000 or more compared to current state-of-the-art instrumentation such as airborne telescope SOFIA. Cryogenic spectrometers, operating at balloon altitudes, have game-changing capabilities, but achieving this goal while remaining within balloon payload mass limits requires ultra-light cryostats. This project is developing an ultra-light cryostat and demonstrates the ability to transfer cryogenic liquids between dewars at balloon altitudes.
