Gemini IV
Mission / eventCompleted
Four days in orbit and Ed White's spacewalk turn Gemini 4 into America's first long-duration flight and first EVA
Gemini 4 carried James McDivitt and Ed White for four days, more than doubling the duration of any previous American crewed mission. An early attempt to approach the spent Titan II showed how difficult orbital would be without precise procedures and navigation. White then left the cabin for 23 minutes using a handheld maneuvering gun, becoming the first American to walk in space. The flight tested crew endurance, life support, tracking, experiments, and a new center while giving NASA both a landmark EVA success and hard operational lessons for later rendezvous missions.

View of the Gemini-Titan 4 spacecraft launch
S65-29639 (3 June 1965) --- The Gemini-Titan 4 (GT-4) spaceflight launches from Cape Kennedy's Pad 19 at 10:16 a.m. (EST) on June 3, 1965. The GT-4 spacecraft carried astronauts James A. McDivitt, command pilot, and Edward H. White II, pilot, on a four-day, 62-revolution mission.
Astronaut Edward White during first EVA performed during Gemini 4 flight
S65-34635 (3 June 1965) --- Astronaut Edward H. White II, pilot on the Gemini-Titan 4 spaceflight, is shown during his egress from the spacecraft. His face is covered by a shaded visor to protect him from the unfiltered rays of the sun. White became the first American astronaut to walk in space. He remained outside the spacecraft for 21 minutes during the third revolution of the Gemini-4 mission. He wears a specially designed spacesuit for the extravehicular activity (EVA). In his right hand, he carries a Hand-Held Self-Maneuvering Unit (HHSMU) with which he controlled his movements while in space. He was attached to the spacecraft by a 25-feet umbilical line and a 23-feet tether line, both wrapped together with gold tape to form one cord. He wears an emergency oxygen supply chest pack. Astronaut James A. McDivitt is command pilot for the Gemini-4 mission. EDITOR'S NOTE: Astronaut Edward H. White II died in the Apollo/Saturn 204 fire at Cape Kennedy on Jan. 27, 1967.
RECOVERY - GEMINI-TITAN (GT)-4 - ATLANTIC
S65-33490 (7 June 1965) --- A United States Navy frogman team participates in the recovery of the Gemini-Titan 4 (GT-4) spacecraft. The USS Wasp was the prime recovery ship for the Gemini-4 mission. The crew of the Gemini-4 spaceflight was astronauts James A. McDivitt, command pilot, and Edward H. White II, pilot.

Failed stage pursuit teaches a rendezvous lesson
Repeated attempts to approach the Titan consume propellant and demonstrate why orbital needs calculated phasing maneuvers.

Trained for the mission but did not count as flown unless reassigned to the prime crew.
Mission Purpose
2 sources- Operate the Gemini spacecraft and its two-person crew for four days to extend American endurance and evaluate systems over a multi-day mission.
- Approach and station keep with the Titan II second to gather practical experience.
- Conduct the first American and evaluate the pressure suit, umbilical, handheld maneuvering unit, and crew procedures outside the cabin.
- Complete medical, navigation, radiation, photography, and spacecraft experiments before guided and recovery.
Planned Flight Plan
2 sources- June 3, 1965
Launch into a four-day mission
Gemini 4 begins the longest American crewed flight yet and activates the new Center in Houston.
- First orbit
Attempt station keeping with the Titan
McDivitt tries to close on the spent second stage, revealing that intuitive pursuit consumes fuel and does not produce orbital .
- Third orbit
Conduct the first American EVA
White exits with a handheld gas gun, moves outside for about 23 minutes, and returns after exhausting the maneuvering unit's gas.
- June 7, 1965
Complete endurance flight and recover
After 62 orbits of systems, medical, and experiment work, Gemini 4 returns to the western Atlantic.
Mission Timeline
