NASA Mulls Magnetic Shield For Mars To Make It Habitable For Humans
Mar 09 2017
The director of Nasa's planetary science division, James Green, said that scientists would like to use an artificial magnetosphere, which should help protect Mars from harmful radiation from the sun, Newsweek reported. According to PerfScience, the artificial magnetic shield proposed by the NASA scientists could restore "water and atmosphere on Mars". But it might not have been always so. The release of the greenhouse gas Carbon dioxide into the atmosphere would then start the process of melting the water trapped in the ice cap. The man-made magnetic field created by NASA scientists would not have to cover the entire planet to work, though creating such a shield and testing it out on Mars will likely be not happen for several years.
The shield would consist of a giant dipole powerful-enough to generate an artificial magnetic field.
Green said that launching a "magnetic shield" to a stable orbit between Mars and the sun could shield the planet from high-energy solar particles. Jim Green said the magnetic shield would eliminate most of the solar wind erosion processes that occur with the Martian ionosphere and upper atmosphere, allowing the atmosphere to grow in temperature and pressure over time.
Scientists working at the USA space agency think that launching a sufficiently powerful magnetic shield into space could serve as a replacement for the Red Planet's own lost magnetosphere, the natural shield that prevents charged particles from reaching the surface of a planet.
United States space agency NASA has an innovative project that it is mulling over to make Mars habitable and it involves a giant magnetic shield. Even if there is still some hearty microorganism living on the Red Planet, it's not suitable for human habitation without a great deal of protective equipment. Ultimately, with an atmosphere and liquid water, Mars may be able to achieve habitable status. With the human colonisation idea getting a push, NASA is devising ways to make the planet a habitable one for the human species to thrive there.
Radiation from the Sun would be immediately and rapidly deflected, but it is unclear how long it would take for the atmosphere of Mars to thicken, and for the temperature to increase enough to create liquid water and sustain long-term human colonists.
"We're trying to inspire people to imagine what we would need to do to colonize Mars".
Similar to the atmosphere of the Earth, an enhanced atmosphere would be allowing larger landed mass to shield against most of the solar particle and cosmic radiation which in turn will be extending the ability of oxygen extraction and provide greenhouse gasses to exist for the production of plants.
"The solar system is ours, let's take it".
The Nasa scientist added: "Perhaps one-seventh of the ancient ocean could return to Mars". Green argued, would allow for human explorers to study the planet in much greater detail, and help determine its habitability, since numerous elements that pointed towards Mars being habitable in the past would slowly seep back into and onto the planet's environment.
