Gemini 10

  1966-066A

---

Gemini 10 was crewed by John Young and Michael Collins. The mission saw rendezvous with both TDA 5 and TDA 3, the Gemini 8 target vehicle.

In the 25-minute EVA, Collins used the gas gun to propel himself across open space to the Agena. In the course of two trips he retrieved a micrometeorite package from TDA 3. The cabin was repressurized after 40 min 8 s. It was depressurized a final time at 0052 on Jul 21 for a 2 min 52s equipment dump.

Retrofire was 92.8m/s aft, 35.4 m/s down, 20 deg pitch down. The spacecraft was recovered from the Atlantic by the USS Guadalcanal after a splashdown at 26 44 07 N 71 57 W.
