Crash Highlights Lack of Space Traffic Control

From Discovery News Top Stories : Discovery Channel:

NASA and the military play close attention to the stuff flying around their spacecraft and regularly scoot them up or down to give passing objects wide berth. But when it comes to privately operated satellites, there is no Federal Aviation Administration for space. "There is no universal space traffic control," said Nicholas Johnson, an orbital debris expert at NASA's Johnson Space Center in Houston. "NASA works with the Department of Defense to look ahead and see if any debris or operational spacecraft are coming close to one of our vehicles, like the International Space Station, the space shuttle or one of our satellites. "If we see something coming, we get out of the way, but not every operator does what we do," Johnson told Discovery News. A communications satellite owned by Iridium Satellite collided with a defunct Russian spacecraft about 490 miles above northern Siberia on Tuesday. The crash created clouds of debris that could be even larger and more hazardous than the wreckage left behind by the explosion of a Chinese satellite two years ago in a widely criticized weapons test. "We probably won't know until a few days. It takes a while for debris to spread out and for us to get a good head count," said Johnson. Private companies can tap the DoD's orbital tracking information, but they would have to pay for it. "It's up to individual satellite operators to reach agreement to get that service. We pay the DoD to do that service," NASA's Johnson added.
