1977 in spaceflight

Spaceflight in 1977 included some important events such as the roll out of the space shuttle orbiter, Voyager 1 and Voyager space probes were launched. NASA received the space shuttle orbiter later named Enterprise, on 14 January. This unpowered sub-orbital space plane was launched off the top of a modified 747 and was flown unmanned until 13 August until a manned crew landed the Enterprise for the first time.
