The OV2 (Orbiting Vehicle 2) series satellites were originally built for project ARENTS (Advanced Research Environmental Test Satellite), which was intended to obtain supporting data for the Vela program. After the cancellation of the ARENTS program, the already built hardware was reused for OV2, a low-cost series of experimental satellites, which were to be launched for free on Titan-3C test flights to very different orbits.
Elliptical OrbitPioneer A to E (Pioneer 6 to 9 after launch) were a series of five solar-orbiting, spin-stabilized, solar-cell and battery-powered satellites designed to obtain measurements of interplanetary phenomena from widely separated points in space on a continuing basis.
Heliocentric N/AGemini 6A was the fifth crewed mission of NASA's Project Gemini. The mission was commanded by Command Pilot Walter M. Schirra, Jr. and Pilot Thomas P. Stafford. The mission achieved the first crewed rendezvous with the Gemini 7 spacecraft. The mission began on December 15, 1965, 13:37:26 UTC and ended on December 16, 1965, 15:28:50 UTC.
Low Earth OrbitThe FR 1 (France 1) spacecraft was a small spacecraft carrying two experiments. One was designed to observe VLF signals from earth-based transmitters, and the other was an electron density probe measuring electron concentration at the satellite.
Low Earth OrbitGemini 7 was the fourth crewed mission of the NASA's Project Gemini. The mission was commanded by Command Pilor Frank F. Borman, II and Pilot James A. Lovell, Jr. The crew spent nearly 14 days in space, and their spacecraft was the passive target for the first crewed space rendezvous performed by Gemini 6A. The mission began on December 4, 1965, 19:30:03 UTC and ended on December 18, 1965, 14:05:04 UTC.
