|NASA and Terraforming|
NASA has released a new study detailing how perfluorocarbons could be
used to terraform Mars. Using PFCs, of which octafluoropropane seemed to be the
effective, NASA's computer model found that only 300 ppm could start a
run-away greenhouse effect. Dr. Margarita Marinova and others at NASA
Ames Research Center found that the idea was "completely practical."
Dr. Marinova published
his findings in the Journal of Geophysical Research - Planets.
"Bringing life to Mars and studying its growth would contribute to our
understanding of evolution, and the ability of life to adapt and
proliferate on other worlds... Since warming Mars effectively reverts
it to its past, more habitable state, this would give any possible
dormant life on Mars the chance to be revived and develop further." The
gasses would have to be made on Mars and preferably during manned
missions. The simulations found that it would take centuries for the
entire terraforming process to be completed, although not all possible factors that could speed up the process were included
in the study.
