Gemini 5 Evaluation Pod



The Gemini 5 Rendezvous Evaluation Pod (REP) was ejected from the Gemini 5 spacecraft for simulated rendezvous maneuver experiments. The pod was launched with the Gemini 5 spacecraft on 21 August 1965 at 8:59:59 a.m. EST (13:59:59.518 UT). The REP was designed to be used as a rendezvous target for the Gemini 5 spacecraft after ejection. The REP contained an Agena rendezvous radar transponder, flashing beacons, batteries, and antenna. The REP was mounted on the back of the Gemini spacecraft. At 2 hours 25 minutes after launch, Gemini 5 was yawed 90 degrees to the right and the REP was ejected by explosive charges at a velocity of roughly 1.5 meters/sec. The plan called for Gemini 5 to manuever away from the REP, 10 km below and 22.5 km behind the REP, and then rendezvous with the REP for training and equipment evaluation. Due to fuel cell problems in the Gemini 5 spacecraft the REP exercise was abandoned about 4 hours into the mission and the REP was left in Earth orbit.
