Life is more likely underground than on the surface of Mars – new study informs

Recent research has suggested that the subsurface environment of Mars may be more suitable for human habitation than the surface.

According to a report published in the journal Geophysical Research: Planets, minerals found in fissures in Gale Crater, probed by America’s Curiosity rover, have more habitable properties than elements on the surface.

The Curiosity rover landed in the crater, a predicted arid crater, to look for potential life on Mars. The Gale Crater on Mars is known for its cold and extreme temperatures that go as low as -70 degrees Celsius

The rover continues to test soil samples there. Some of the soil samples there were sent to Earth last week by a small rocket. When it reaches Earth, scientists will study it in a laboratory here.

Meanwhile, data analyzed by the Neutron Spectrometer’s Dynamic Albedo of Neutrons, or DAN, revealed that the cracks and fissures between its vast surface have water-rich and radiation-shielding conditions.

Light-colored opaline silica features found between the cracks show traces of a vast fluid flow during Mars’ geologic history and the exposed lithic structure. But there is evidence that liquids were only present on the planet for a short period of time. It is followed by dry cold weather only.

In addition, researchers examined old images sent by the Curiosity rover and found some land cracks. It continues to expand and the rock formations visible within it show traces of recent times. It also contains a solution of silica and water, which are essential for life.

It is similar to dissolving sugar or salt in water. If there is too much salt, it starts to settle down. Similarly, researchers say that watery environments on the surface of Mars may have studied underground in search of a safe haven from the harsh conditions on the Martian surface.
