The U.S. Space Shuttle program started with the awarding of the contract to Rockwell International's Space Transportation Systems Division. There were 6 shuttles built, Enterprise OV-101 (Orbital Vehicle) for testing, Columbia OV-102, Challenger OV-099, Discovery OV-103, Atlantis OV-104 and Endeavour OV-105. The first of 135 Space Shuttle missions took place April 12, 1981 and lasted 2 days 6 hours when STS-1 (Space Transportation System) was launched using Space Shuttle Columbia. Of the 135 mission launches there were 2 tragedies when Columbia and Challenger plus their crews were lost.

The scheduled launch of Space Shuttle Endeavour OV-105 was December 3, 1998 was scrubbed but one day later the shuttle launched successfully. On board was the Unity connecting module known as Node 1. This unit was connected to the first module called Zarya that had been placed in orbit earlier by a Russian rocket. There eventually would be two more modules called Harmony and Tranquility added to Node 1 to complete the ISS build. On December 15 the crew of six landed completing the first trip to the ISS..
