NASA: Mars ‘ atmosphere will restore the magnetic shield

Contents

According to scientists, Mars was cold and lifeless place due to the loss of the magnetic field around 4.2 billion years ago. Planet was left virtually defenseless against solar winds, which is gradually carried away a large part of the atmosphere and continue to do so at a speed of up to 300 tons of gases per day. NASA are confident that the situation can be corrected with the help of artificial magnetic shield. It will also reduce the levels of radiation that pose a danger to astronauts.

What I want to do

Shield at a distance of 1.08 million kilometers from Mars of all time is on a direct line between the planet and the Sun

To protect Mars from solar winds and ionizing radiation NASA experts propose to launch a satellite into orbit near the Lagrange point L1, a powerful generator of magnetic field induction of 1 to 2 Tesla (as some magnets in particle accelerators). The model showed that within a few years after activation of the shield, the atmospheric pressure of the red planet will reach half the world (vs 1/110 share today), and a temperature rise of four degrees Celsius would be enough to vaporize the carbon dioxide at the North pole. This will launch the greenhouse effect, the surface will become warmer, the ice will begin to melt and fill the Mars liquid water, which will not immediately evaporate. Scientists, therefore, you can recover up to 1/7 of the Martian oceans.

What’s next?

The magnetic shield continue to work on models and I want to calculate how much you may need time for the transformation of Mars into a “second Earth”, but at NASA there are no plans to implement the project.

To achieve a greenhouse effect on the planet in 2015, Elon Musk has offered to blow up over the Martian poles thermonuclear bomb. I wonder what results will be achieved by combining the two concepts.
