Red Planet once had a thick atmosphere necessary to maintain liquid water

US, Mar 6, 2017: Scientists at NASA have proposed that launching a giant magnetic shield into space to protect Mars from solar winds could give the Red Planet its atmosphere back and make it habitable for humans.

Mars now appears to be a cold desert world and it has no global magnetic field. The cold temperatures and thin atmosphere on the red Planet do not allow liquid water to exist at the surface for long. But it might not have been always so.

Scientists believe that the Red Planet once had a thick atmosphere necessary to maintain liquid water, and a warmer, potentially habitable climate. It is the collapse of the protective magnetic field billions of years ago that eventually made Mars what it is today — cold and arid.

In a presentation at the Planetary Science Vision 2050 Workshop in Washington, DC last week, NASA scientists proposed that launching a giant magnetic shield into space between Mars and the Sun could help the Red Planet restore its atmosphere and make it suitable for humans to colonise in the future.

The US space agency thinks a powerful-enough magnetic shield launched into space could serve as a replacement for Mars’s own lost magnetosphere, ScienceAlert reported on Monday.

Launching an “artificial magnetosphere” into space between Mars and the Sun could hypothetically shield the Red Planet in the extended magnetotail that trails behind the protective field, NASA’s Planetary Science Division director Jim Green was quoted as saying.

“This situation then eliminates many of the solar wind erosion processes that occur with the planet’s ionosphere and upper atmosphere allowing the Martian atmosphere to grow in pressure and temperature over time,” the researchers explained in an accompanying paper.

The researchers believe that the magnetic shield could help Mars regain some of its lost Earth-like habitability within the space of a couple of generations. (IANS)

NASA's next mission.

A Falcon 9 rocket blasted off Wednesday carrying SpaceX’s first high-priority science mission for NASA, a planet-hunting space telescope whose launch had been delayed for two days by a rocket-guidance glitch.

The Transit Exoplanet Survey Satellite, or TESS, lifted off from Florida’s Cape Canaveral Air Force Station at 6:51 p.m. EDT, starting the clock on a two-year quest to detect more worlds circling stars beyond our solar system that might harbor life.

The main-stage booster successfully separated from the upper stage of the rocket and headed back to Earth on a self-guided return flight to an unmanned landing vessel floating in the Atlantic.

The first stage, which can be recycled for future flights, then landed safely on the ocean platform, according to SpaceX launch team announcers on NASA TV.

Liftoff followed a postponement forced by a technical glitch in the rocket’s guidance-control system.  VOA
