Gemini III proved that man could maneuver an orbiting space craft. Gemini IV proved that man could maneuver himself in space. Gemini IV was the 2nd manned flight in the Gemini Program and only the 10th manned American spaceflight. In 4 days, James McDivitt and Edward White circled the Earth 66 times.

The extravehicular activity was performed during the third revolution of the Gemini 4 spacecraft. White is attached to the spacecraft by a 25-ft. umbilical line and a 23-ft. tether line, both wrapped in gold tape to form one cord. In his right hand White carries a Hand-Held Self-Maneuvering Unit (HHSMU). The visor of his helmet is gold plated to protect him from the unfiltered rays of the sun.
During this mission, Ed White emerged from the safety of the Gemini capsule and floated in space for about 20 minutes.

One of the new tools used on Gemini IVs mission was the Hand Held Manned Maneuvering Unit that provided a method of control direction during EVAs.
On the 48th revolution there was a computer failure and a malfunctioning thruster complicated reentry procedures and gave them a rougher reentry.
Splashdown was 43 nautical miles short of the intended landing spot.
