Gemini 10

Gemini 10With the docking and EVA goals of the Gemini program still unmet, and with the first Apollo missions looming ahead in the mission schedule, Gemini 10 lifts off with a lot riding on it (in addition to astronauts John Young and Michael Collins). Over the course of nearly three days, the Gemini 10 crew makes up for lost time, successfully docking with an Agena booster and changing the vehicle’s orbital altitude to 188 miles – a new distance-from-Earth record for a manned spacecraft. Collins conducts two spacewalks, but the lack of handgrips on the exterior of the Gemini capsule frustrates his efforts. Gemini 10 returns after three days in space.
