Be sure to pack a few floating arms and a really great workout when flying to Mars. You can hide a whole world of lakes full of water under the southern ice cap of the dry and dusty planet.

A new study led by researchers at Roma Tre University in Italy reinforces the argument for 201

8 discovery of a hidden lake under the Martian polar iceand then expands the find to include three new lakes.

The researchers used radar data from the European Space Agency’s Mars Express orbiter to make their initial detection of liquid water.

“Now, taking into account more data and analyzing it differently, three new reservoirs have been discovered,” ESA said in a statement Monday. The team published its study in the journal Nature Astronomy on Monday.

The lakes seem to lurk beneath a salty layer of ice. The largest lake is about 30 miles (30 miles) long with a number of smaller lakes around it.

Researchers expect the water to be incredibly salty to stay liquid at low temperatures. Separately A 2019 study suggests volcanic activity can help prevent water freezing, but the current paper relies heavily on the salt concept.

“While it is not possible for water to remain stable on the surface today, the new result opens up the possibility of a whole system of ancient lakes existing underground, perhaps millions or even billions of years ago,” ESA said.

People are busy looking for signs of life – especially evidence of ancient microbes – on Mars. NASA’s new rover Perseverance will continue this search from the surface of the red planet. Liquid water tanks would be a particularly tempting place to look for life, but reaching these reservoirs would be extremely difficult. There is 1 mile (1.5 kilometers) of ice on the road.

We may not get big answers from the South Pole of Mars, but this may give us a future goal to explore once our technology meets the challenge.
