HONG KONG: According Curiosity Rover of the National Aeronautics and Space Administration (NASA), Mars may have had water on its surface. Javier Martin-Torres of the Spanish Research Council has said that water is a necessity for life and this mission is to find water on the surface of Mars. Recent research by Rover revealed that it has been found perchlorate in the surface that is able to absorb moisture from the atmosphere.
Since Curiosity landed in Gale, a 154 km-wide crater on the surface of Mars in 2012, a tool that has traveled more than 10 miles from the landing site to Mount Sharp, carries some research samples. Of the journey, scientists have discovered calcium perchlorate in soil where calcium is in proper condition to absorb water from the atmosphere.
Torres is lead author of a study published on Monday in Nature journal.
Since Curiosity landed on Mars in a 154km-wide crater called Gale in 2012, it has travelled more than 10km from the landing site towards Mount Sharp and carried several studies.
The scientists discovered calcium perchlorate in the soil, which under the right conditions absorbs water vapour from the atmosphere. The measurements from Curiosity’s weather monitoring station show these conditions exist at night and just after sunrise in the winter.
Using measurements of humidity and temperature at the surface and atmosphere of the planet, scientists could approximately calculate the amount of water that is absorbed.
