Repost Of “Emissions of Black Carbon by Rockets – Can You Spot The Irony?” By Darin Toohey

There is a quite interesting post by Darin Toohey of the University of Colorado at Boulder titled

Emissions of Black Carbon by Rockets – can you spot the irony?

where it is clear that his message on the climate risks of these launches is not being heeded.

 Darin’s research on this topic is presented in the posts

“Limits On The Space Launch Market Related To Stratospheric Ozone Depletion” By Ross et al. 2009

News Article “ Boulder scientists: Space tourism could contribute to climate change

The current post by Darin is quite interesting as evident in the title he chose

Emissions of Black Carbon by Rockets – can you spot the irony?

“The Sierra Nevada Corporation (SNC) Space Systems Group announces the successful completion of two critical milestones for NASA’s Commercial Crew Development (CCDev) Program. On September 21, 2010, SNC completed three successful test firings of a single hybrid rocket motor in one day. ”  (SNC Press Release, Oct. 11, 2010)

“If the space tourism industry matures to the point that 1,000 hybrid-powered suborbital flights depart annually, those trips would deposit roughly 600 metric tons of soot into the stratosphere each year. Over decades of launches, those emissions would form a persistent and asymmetric cloud over the northern hemisphere that could impact atmospheric circulation and regional temperatures far more than the greenhouse gases released into the stratosphere by those same flights.”  (Scientific American,  October 23, 2010)

“[T]he rocket fuel that most companies plan to use — a solid synthetic rubber that is burned with a liquid nitrous oxide — creates far more soot than more standard rocket fuels that mix together hydrogen and oxygen.” (Boulder Daily Camera, October 25, 2010)

” ‘This is at the absolute forefront of the way you can do scientific research today,’ said SwRI’s Alan Stern, who is leading the institute’s suborbital program. (SwRI) stepped out front, and we didn’t just put our toe in the water… I expect that these scientists will be the first of many to fly to space commercially[.] As the scientific community realizes that they can put payloads and people into space at unprecedented low costs, the floodgates will open even wider.” (Boulder Daily Camera, February 28, 2011)

“U.S. Sen. Mark Udall, D-Colo., toured Sierra Nevada and the new space vehicle Tuesday as part of his Colorado Workforce tour, then led a town hall-style discussion with about 150 employees. ‘I’m here to be an advocate for the Colorado aerospace industry,’ Udall said.” (Boulder Daily Camera,  March 23, 2011)”
