Former NASA director James Green says the two planets could be ‘terraformed’ using shields to protect them from the Sun
Building a magnetic shield between the Sun and Mars could protect the planet from solar particles that erode its fragile atmosphere, eventually making it “terraform itself” to better suit humans, NASA’s former director has said.
James Green explained to the New York Times that more heat could be captured by blocking charged rays. This would prevent them from stripping away the outer layer. This will raise the planet’s temperature and pressure to a point where explorers can walk on the surface without a spacesuit and grow plants in the soil.
“Stop the stripping, and the pressure is going to increase. Mars will start to terraform itself. That’s what we want: the planet to participate in this any way it can,”Green stated.
The Red Planet’s surface temperature has been measured at minus 62 degrees Celsius, while its atmosphere is around 100 times thinner than on Earth. This is his concept. “doable,”Green stated that there was “several scenarios”On the construction of the magnetic shield, he suggested that Venus might be geoengineered in a similar manner by creating a “physical shield that reflects light,”Bring the temperature down.
Terraforming begins at 60 microbars. [of atmospheric pressure]It is 10 times more than where we currently are. That’s called the Armstrong limit, where your blood doesn’t boil if you walked out on the surface.
This proposal was presented by the NASA Planetary Science Vision 2050 Workshop in 2017. This presentation was a combination of simulations, models and predictions that this technology might return. “one-seventh of the ancient ocean” to Mars by freeing frozen water at the planet’s polar cap.

“The solar system is ours, let’s take it. That of course includes Mars, and for humans to be able to explore Mars, together, with us doing science, we need a better environment,”He had stated at that time that the climate could stabilize in just a few years.
Green, however, told The New York Times his ideas may not be accepted by the Times. “well received”Scientists, Since “planetary community does not like the idea of terraforming anything.”
