Find evidence of groundwater around Mars?

Mars today may look like an arid, dusty planet, but it used to contain a huge system of groundwater. Recent researchers have found evidence to confirm this.

The Science alert reported on Feb. 28 that many Mars hypotheses previously indicated that it was possible that it once contained a huge amount of water both above and below its surface and now, the houses Research by the European Space Agency (ESA) has evidence supporting these assumptions.

Francesco Salese, an ESA researcher, said: "In the past, Mars had the potential to be a water world but climate change caused the water to change to the surface of a lake and aquifer."

He also said the team found the first geological evidence of the Martian groundwater system.

This finding is based on the use of data from three devices: high-resolution digital camera equipment (HRSC) on ESA's Mars Express spacecraft, high-resolution imaging science test camera (HiRISE) of NASA and Scene Camera on NASA's Mars Explorer.

The team discovered at two craters in the northern hemisphere of Mars. They found the characteristics suggesting that the craters used to contain water and the flow of water changed, receding over time.

They can even estimate the water level in the past and find that they are consistent with the hypothesis of an ocean from 3 to 4 billion years ago on Mars.

Water is an important indicator of life and therefore any evidence of water on the red planet shows that the possibility of a high planet may have lived.
