1965-06-03 USA Gemini 4

Gemini 4 (GT-4), launched on June 3, 1965, was the second Gemini manned flight crewed by James A. McDivitt and Edward H. White II. The highlight of the mission was the first American extra-vehicular activity (EVA) (or known as “space walk”), during which White remained tethered outside the spacecraft for 22 minutes. NASA moved up the “space walk” schedule after Soviet cosmonaut, Alexei Leonov, performed the first ever EVA on March 18 1965. Gemini 4 was the first multi-day space flight by the US to show that it was possible for humans to remain in space for the length of time required to fly to the moon and back.

The Gemini program was managed by the Manned Spacecraft Center (MSC), located in Houston, Texas. Starting with Gemini 4, MSC's Mission Control Center took over flight control duties from the Mercury Control Center at Cape Canaveral Air Force Station. Gemini 4 was the first flight to be controlled by the new Mission Control Center at the Manned Spacecraft Center in Houston, Texas. At different times the Gemini 4 spacecraft came into range of 20 tracking stations spread from the Canary Islands to Tananarive. Data beamed from the spacecraft to the stations was relayed to the computer center at Goddard near Washington, D.C. There it was digested and fed to the Mission Control Center at Houston.
The medical condition of the Gemini 4 astronauts were checked when they pass over Grand Canary station.
