TRS Mk2 [Smithsonian]
From 1962 the US Air Force launched a series very small technology satellites called ERS (Environmental Research Satellites). The satelltes were built by TRW Systems Group for the United States Air Force Office of Aerospace Research (AFOAR). Depending on the shape, these satellites are also referred to as the Tetrahedral Research Satellite (TRS) or Octahedral Research Satellite (ORS).
The basic configuration of the TRS Mk.2 spacecrafts was a regular octahedron measuring 23 cm on a side. Solar cells mounted on each side of the faces provide sufficient electrical power to operate the experiments and and the telemetry system when the satellite is illuminated by the sun. No internal battery or command system were provided. The satellite subsystems consisted of electrical power, antenna, telemetry, experiments, and mechanical structure.
