Streak or STP-R1 is an Defense Advanced Research Projects Agency (DARPA) experimental satellite, which remains largely classified.
Streak is expected to demonstrate technology for future low-earth-orbit satellites and gather information about conditions that could affect future low-earth-orbit spacecraft.
Information released by DARPA indicates Streak is fitted with two instruments:
The vehicle will characterize the orbital regime, demonstrate operational feasibility from a command and control standpoint and also from a platform perspective for future DoD missions. General Dynamics C4 Systems / Spectrum Astro Space Systems built the craft in Gilbert, Arizona, based on their SA-200HP platform.
Streak reentered on 28 June 2006.
