STS 104



STS 104 is an American shuttle spacecraft that was launched from Cape Canaveral at 09:04 UT on 12 July 2001. It carried a crew of five American astronauts and a major unit called ISS Airlock, and docked with the ISS at 03:08 UT on 14 July 2001. The six tonne Airlock is a pressurizable unit consisting of two cyclinders of diameter four meters and a total length six meters. They were installed and secured by the crew during three EVAs. The Airlock can be pressurized by the externally mounted high pressure oxygen-nitrogen tanks, and will be the sole unit through which all future EVAs will take place. (Until now, all EVA entries/exits have been through a Russian module in ISS, with non-Russians having to wear Russian space suits.) Another payload was the "EarthKAM" of middle/high school interest. It will allow pupils to command picture-taking of chosen spots on Earth; there were expected to target 2,000 spots. The shuttle also carried out pulsed exhaust during maneuvers to enable better understanding of the formation of HF echoes from the shuttle exhaust. The echoes were obtained by ground based radars in an experiment called SIMPLEX (Shuttle Ionospheric Modification with Pulsed Local EXhaust). The shuttle landed back in Cape Canaveral at 03:39 UT on 25 July 2001.
