The dream of terraforming Mars is being suggested by more and more experts as a way to make it more hospitable for humans.
Jim Green, the outgoing director of NASA's planetary science division, told The New York Times that it might be possible to warm the Martian atmosphere by placing a massive magnetic shield between it and the Sun.
The idea is to stop the solar wind from blowing the Red Planet with radiation, which would allow particles to escape its thin atmosphere.
Green told the newspaper that it was doable. The pressure is going to increase if the stripping is stopped. Mars is going to terraform itself.
He explained that the temperature goes up when the pressure goes up.
The Planet Umbrella.
Green is not the only one interested in the concept. Hakeem Oluseyi, a former NASA scientist, went on CNN this week to discuss Green's vision.
He said that the location of the spaceship has to be between Mars and the Sun. You have to calculate the amount of deflection based on the location.
It is like an umbrella for a planet.
Green is preparing to submit his idea for a paper to one of the surveys that scientists choose what space exploration efforts to fund decades ahead as part of.
It will be hard to convince the scientific community of the idea.
It doesn't fit in anywhere. Technical feasibility is one of the things that we look at when evaluating the idea.
He said that it was a tough sell because the scientific community wouldn't admit you were right.
