Scientists have plan to bring back Mars' oceans
Doing so would thus help protect early human settlers on Mars from the harsh radiation and vaccum of space.
Speaking at the Planetary Science Vision 2050, Green said: "The solar system is ours, let's take it". The idea was mooted at the three-day Planetary Science Vision 2050 Workshop, which started on February 27, at the Nasa headquarters in Washington DC.
Per the scientists' report on what they admit is a "fanciful" topic, this "enhanced" atmosphere would be more conducive to human exploration, offering more possible oxygen extraction, more plant growth in "open-air" greenhouses, and the ability of larger structures to land on the planet's surface.
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.
The Magnetotail refers to the wide elongated extension of the earth's magnetosphere on the side facing away from the Sun. However, when its protective magnetic field (also called magnetosphere) collapsed over 3 billion years ago, it got bombarded by solar winds and radiation, which caused it to start losing its atmosphere.
Technically the magnetic shield will comprise a huge dipole functioning as a closed electric circuit for generating the artificial magnetic field.
Now, onto the magnetic shield.
Alexis Sanchez may leave Arsenal after been dropped against Kops
Ibrahimovic also saw a second-half penalty saved by Artur Boruc, preventing him from registering a 27th goal of the season. Arsene Wenger brought him on in the second half and he helped the Gunners get a goal back when he set up Danny Welbeck.
"It has been determined that an average change in the temperature of Mars of about four degrees Celsius will provide enough temperature to melt the Carbon dioxide veneer over the northern polar cap", the presentation revealed.
Green described the idea as involving a "magnetic shield" launched in a stable orbit between Mars and the Sun. Such a field could even result in Mars' atmosphere thickening over time, creating a greenhouse effect, which would increase the planet's surface temperature by up to four degrees, and melt northern polar ice caps - restoring Mars' oceans in the process.
Although Mars has the reputation of being a cold, arid wasteland, the planet is believed to have once had a thick atmosphere that could have sustained deep oceans filled with liquid water.
Researchers noted that although the plan is hypothetical at this point, a small scale magnetosphere that operates on a similar premise does exist and could serve as the model for an enormous shield. But without the stronger magnetic field Mars once had, that planet was not "able to hold gases near to its surface".
"If this can be achieved in a lifetime, the colonisation of Mars would not be far away".
"These new conditions on Mars would allow human explorers and researchers to study the planet in much greater detail and enable a truly profound understanding of the habitability of this planet", the authors write.
The workshop saw one presentation which proposed that a man-made magnetic field be used on the Red Planet.
US condemns 'unacceptable' North Korea missile launches
South Korea and the United States appear to be speeding up the deployment of the THAAD missile defense system to the peninsula. South Korea's military said there was a low chance the missiles were intercontinental ballistic missiles (ICBMs).
