MARS — NASA scientists think it is possible to restore Mars’ oceans by creating an artificial magnetic field that sits in front of the planet. <br /> <br />The concept was shared in NASA’s Planetary Science Vision 2050 Workshop. Scientists think it is possible to place an inflatable structure that generates a magnetic dipole field at the Mars L1 Lagrange Point to form an artificial magnetic shield to protect the planet from solar wind and radiation. <br /> <br />Under this protection, the Martian atmosphere could become thick enough to melt carbon dioxide ice at the northern pole. In time, the atmosphere could spark a greenhouse gas effect that could restore some of Mars’ oceans.
