NASA Wants to Shield Mars
NASA scientists are developing new technology which can convert Mars into a friendly world with a warm climate and liquid water.
The Sun blew the Martian atmosphere away. About four billion years ago, Mars had a magnetic field just like Earth’s, which protected the planet’s atmosphere from harmful solar particles. But when Mars' core cooled, the planet’s protective magnetic field disappeared, and it was converted into a freezing desert. Now, NASA has a plan to give the Red Planet a new, artificial magnetic field using a huge, floating electromagnet.
With the field in place, we can crush rocks to rebuild Mars' atmosphere. Mars will become warmer, the air thicker, and water once again will flow on Mars. Looking to the far future, this artificial magnetic shield will also protect Martian colonists against solar radiation.
According to computer simulations, all these changes would be effective in less than 100 years, meaning that the planet could become habitable long before previously believed. NASA engineers expect to have completed the technology for producing the magnetic shield before 2050.
An electromagnetic shield is to protect Mars against harmful solar radiation.
