50 Years Ago: Gemini GT-2 Test Flight

Mission GT-2 lifts off from Pad LC-19, on January 19, 1965.

Recently, on December 5, 2014 we watched the successful test of the Orion space capsule which will be part of NASA's heavy lift SLS rocket system. Fifty years ago, on January 19, 1964, NASA tested the Gemini capsule in a similar mission profile using the unmanned GT-2 test capsule on a Titan rocket. The sub-orbital flight was designed to fling the capsule into space and test the heat shield as it made a fiery re-entry through the atmosphere. That's exactly what the recent Orion flight was designed to do.

The flight was a total success. The equipment aboard the capsule included an automatic sequencer designed to send signals at precise moments to fire the second stage, separate the capsule, jettison the storage section behind the capsule, orient the capsule for re-entry, and activate the parachutes. The capsule flew through an arc over the Atlantic Ocean, landing 2127 miles downrange, and splashdown occurred about 52 miles from the recovery aircraft carrier, the USS Lake Champlain.

GT-2 capsule arrives in Cape Canaveral. It has been placed on the equipment storage section (The white cone segments under the capsule).

The capsule was never intended to be manned. Instead, it was packed with early forms of computerized sequencers and test measuring devices to study the effects that re-entry physics would play on the structure of the craft and the simulated astronauts. This capsule eventually would become the first spacecraft to fly in space twice! For the Air Force's Manned-Orbital-Laboratory program (MOL), a hatch would be placed through the heat shield so that an astronaut could leave the cockpit and enter a spy-instrument control section that would be placed behind the capsule.

The capsule wears the US Air Force insignia that was painted on it for its mission in 1966. It was jam-packed with equipment, no room for even a little astronaut in there!

Another view of the capsule. The entire craft is covered with a protective plastic shield to preserve it. 

Not my picture. Another view that shows the hatch placed after mission GT-2.
