Gemini 4

Gemini 4The second manned Gemini flight, Gemini 4, lifts off with Jim McDivitt and Ed White aboard for a four-day mission. Four hours into the flight, White becomes the first American spacewalker, controlling his movement with a handheld device with small jets allowing him to change his own orientation, though he is tethered to the Gemini capsule at all times. This is the first NASA flight overseen from the new Manned Space Center constructed in Houston, Texas, and the first to be broadcast live worldwide.
