Using ground-penetrating radar, scientists detected a massive reservoir of frozen water sandwiched by layers of sand beneath the northern polar ice cap on Mars. This reservoir contains so much ice that, if melted and brought to the surface, it would submerge the entire planet.

“This was a surprise even for us,” Stefano Nerozzi, the lead author of the new paper and a PhD student at the University of Texas at Austin, told Gizmodo in an email.

A USC team won the collegiate space race by sending a rocket above the Kármán line, the imaginary boundary that marks the end of Earth’s atmosphere.

Researchers believe they’ve spotted the remains of ancient Martian ice caps mingled with layers of sand, all a mile below the Red Planet’s modern north pole.

Astronomers think liquid water could flow on its surface.

It’s within its star’s habitable zone.
