STPSat 1

STPSat 1 [AeroAstro]

STPSat 1 is an experimental spacecraft for STP (Space Test Program), which hosted several experiments. The 3-axis stabilized spacecraft is built by AeroAstro.

STPSat 1 contained following experiments:

  • the optical SHIMMER payload
  • CITRIS, a Certo Beacon Transmitter experiment
  • MEPSI, a experiment to deploy two pico-satellites

At the end of its mission it was to deploy two MEPSI nanosatellites, but these were de-manifested shortly before launch due to Aerospace Corps funding constraints and inability to finish the pico-sats on time. The launcher itself remained on board, but was loaded with dummy masses, which were not to be deployed.

It was launched as a secondary payload from the first STP mission on an Atlas-5(401) rocket.
