Product Name: Gemini 1

Product Description

Gemini 1 was an uncrewed orbital test of the Titan 2 launch vehicle, the Gemini spacecraft structural integrity, and the launch vehicle-spacecraft compatibility. The test covered all phases through the orbital insertion phase. Other objectives were to check out launch vehicle-spacecraft launch heating conditions, launch vehicle performance, launch vehicle flight control system switch-over circuits, launch vehicle orbit insertion accuracy, and the malfunction detection system. This was the first production Gemini spacecraft and launch vehicle. Mission Profile Launch of Gemini 1 took place at 11:00:01 a.m. EST (16:00:01.69 UT) from Complex 19. Six minutes after launch, the Titan 2 booster placed the Gemini spacecraft and the attached 2nd stage in a 160.5 x 320.6 km orbit with a period of 89.3 minutes. An excess speed of 22.5 km/hr sent the spacecraft 33.6 km higher than planned. Mission plans did not include separation of spacecraft from the 3.05 meter diameter, 5.8 meter long Titan stage 2, both orbited as a unit. The planned mission included only three orbits and ended about 4 hours 50 minutes after launch with the third pass over Cape Kennedy. The spacecraft was tracked until it reentered the atmosphere and disintegrated on the 64th orbital pass over the southern Atlantic on April 12. The systems functioned well within planned tolerances and the mission was deemed a successful test.
