Gemini-Titan 8 (GT-8) spacecraft, carrying NASA astronauts Neil Armstrong, command pilot, and David Scott, pilot, successfully launches from Kennedy Space Center (KSC) at 11:41 a.m. (EST), on March 16, 1966. Gemini 8 successfully rendezvoused and docked with the Agena Docking Target Vehicle during their spaceflight. 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.
