50th anniversary of NASA's Gemini 8 mission

NASA astronaut David R. Scott, prime crew pilot on Gemini 8, undergoes water egress training in a special tank in Building 260A at the Manned Spacecraft Center (MSC), in Houston, Texas, on January 5, 1966. An MSC swimmer assists in the training exercise. A full-scale model of a Gemini spacecraft floats in the water beside Scott. March 16, 2016 marks the 50th anniversary of NASA's Gemini 8 mission, the sixth manned spaceflight conducted during the United States' Project Gemini program. The primary objective of the mission, the successful docking of two spacecraft in orbit, a first in spaceflight, was a success though the crew would experience a critical in-space system failure, forcing them to abandon the mission prematurely.
