Gemini 8: Applications, Flight & Thruster incident: cause and outcome

Gemini 8 (officially Gemini VIII) was the sixth crewed spaceflight in NASA's Gemini program. It was launched on March 16, 1966, and was the 14th crewed American flight and the 22nd crewed spaceflight overall. The mission conducted the first U.S. docking of two spacecraft in orbit, but also suffered the first critical in-space system failure of a U.S.…
