Chipsat
Cosmic Hot Interstellar Plasma Spectrometer SATellite
Worth $12 million of NASA funding, managed by the University of California
Berkeley's Space Sciences Laboratory. Spacedev as the bus provider, integrator
and operator for the first year will charge approx $5 million.
The CHIPS instrument is designed to diagnose the physical properties of the
plasma in the local bubble. It will carry out for the first time all-sky,
high-resolution spectroscopy of the plasma's diffuse glow using sensitive
detectors tailored to observe in a poorly explored ultraviolet wavelength band.
Communication with the satellite will be via TCP/IP + FTP.
Started serving on 2 Feb 2003.
At end of life, it is learned that the satellite never detected Extreme UV
radiation from the hot interstellar gas. After about 3 years of operation, it
was redirected to look at Extreme UV emissions from the Sun. It was NASA's
first mission to communicate via IP (Internet protocol), and it was used by
NASA's Exploration Initiative to test scheduling systems software in orbit.

The platform features a miniature, high-performance, 300 MIPS flight computer
using a Motorola microprocessor; a miniature, variable power STDN-compatible
S-band Transceiver/Transponder; a miniature, modular power conditioning and
distribution subsystem; the SpaceDev MicroSat-Operating System; the
Internet-based SpaceDev Mission Control and Operations Package.
