Caught part of the Radio 4 program Material World last Thurs on the potential impact of space tourism, with soot pollution of the stratosphere being a key culprit. Given that the development of space tourism looks set to accelerate, this research and debate is very important. The American Geophysical Union is warning that the environmental cost of space tourism will be greater than the $200,000 price tag passengers will be paying to travel on the Virgin Galactic spaceship when voyages begin in 2012. Marty Ross of non-profit research organisation The Aerospace Corporation in California and key author of the AGU's paper, explains why.
