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.
