Space Tourism to Accelerate Climate Change. By Adam Mann, NatureNews, 10/22/10. “Scientists predict that soot from commercial space flight will change global temperatures… The findings, reported in a paper in press in Geophysical Research Letters, suggest that emissions from 1,000 private rocket launches a year would persist high in the stratosphere, potentially altering global atmospheric circulation and distributions of ozone… Private space flight is a rapidly maturing industry. Spaceport America, a launch site in Las Cruces, New Mexico, opened its first runway on 22 October. During the next three years, companies such as Virgin Galactic, headquartered at Spaceport America, expect to make up to two launches per day for space tourists. Meanwhile, the NASA Authorization Act passed by US Congress in September provides US$1.6 billion in private space-flight investments to develop vehicles to take astronauts and cargo into orbit.”
