Launch of Gemini 7 with crew members Frank Borman and Jim Lovell. The Gemini 7 spacecraft was the passive target for the first crewed space rendezvous performed by the crew of Gemini 6A.

Gemini 7, crewed by Frank Borman and Jim Lovell, launched on December 4, 1965 to serve as the passive target for history’s first crewed space rendezvous performed by Gemini 6A.
Launched from Cape Kennedy on December 4, 1965, Gemini 7 carried astronauts Frank Borman and Jim Lovell on a 14-day endurance mission to test human performance in space. Meanwhile, the crew of Gemini 6A flew alongside and executed the first crewed rendezvous in orbit, closing to within mere feet of Gemini 7 without docking. This critical demonstration of orbital rendezvous techniques paved the way for future Apollo missions to the Moon. The mission also gathered valuable biomedical and spacecraft performance data under extended weightlessness. Gemini 7’s success marked a milestone in NASA’s effort to master complex space maneuvers.

The Unity Module, the second module of the International Space Station, is launched.

The Unity Module, the second segment of the International Space Station, is launched into orbit, advancing global space collaboration.
On December 4, 1998, NASA launched the Unity Module aboard Space Shuttle Endeavour on mission STS-88. Known as Node 1, Unity was the first U.S.-built component to join the Russian Zarya module already in orbit. Its six docking ports created a hub for future station elements and visiting spacecraft. The successful space rendezvous and assembly showcased unprecedented international collaboration among 16 nations. Unity's integration laid the groundwork for the ISS's expansion into a cutting-edge laboratory for microgravity research, Earth observation, and human spaceflight. The milestone launch represented a new era in cooperative space exploration and engineering.
