An amateur constructed rocket reached an altitude of 100km and became the first such craft to reach space. This incredible achievement is described here by the ARRL, or the Amateur Radio Relay League. The rocket also carried an avionics package designed by radio amateurs. The rocket apparently transmitted telemetry on the 33cm band and ATV on the 2.4ghz band.
I'm looking forward to seeing some of the pictures from the flight. To all those who worked on the project, hearty congrats!
