“#New NASA study challenges beliefs about water on Mars<\/strong>”

A new study from\u00a0NASA\u2019s\u00a0Jet Propulsion Laboratory and researchers at the\u00a0California\u00a0Institute of Technology<\/a>\u00a0questions whether or not a longheld theory about\u00a0Mars\u00a0still holds water.<\/p>\n

In their research, the team of\u00a0scientists\u00a0posits that a large quantity of the Martian\u00a0planet\u2019s\u00a0water had not escaped into\u00a0space\u00a0due to its low gravity as previously assumed, but instead was trapp<\/a>ed in its crust.\u00a0<\/p>\n

While it is known that abundant water had flown on the planet billions of years ago, the team said that their findings revealed between 30 to 99% of it had been stuck in minerals.<\/p>\n

Their conclusions, published in\u00a0Science magazine<\/a>\u00a0and presented at the\u00a052nd Lunar and Planetary Science<\/a> Conference, were reached by using\u00a0cross-mission data from the agency\u2019s\u00a0Planetary Data System (PDS)<\/a>.<\/p>\n

The data pertained to\u00a0meteorite\u00a0lab work as well as\u00a0NASA Mars Exploration Program missions and the team focused on the quantity of water on Mars over time and the chemical composition of the planet\u2019s current atmosphere.\u00a0<\/p>\n

In particular, they examined the ratio of\u00a0deuterium to hydrogen (D\/H),\u00a0according to a Tuesday news release<\/a>.<\/p>\n

\u201cWhile water is made up of hydrogen and oxygen, not all hydrogen atoms are created equal. The vast majority of hydrogen atoms have just one proton within the atomic nucleus, while a tiny fraction (about 0.02%) exists as deuterium, or so-called \u2018heavy\u2019\u00a0hydrogen, which has a proton and a neutron. The lighter-weight hydrogen escapes the planet\u2019s gravity into space much easier than its denser counterpart,\u201d the release explained. \u201cBecause of this, the loss of a planet\u2019s water via the upper atmosphere would leave a revealing sign on the ratio of deuterium to hydrogen in the planet\u2019s atmosphere: There would be a very large amount of deuterium left behind.\u201d<\/p>\n

But, they say, because the loss of water solely through the atmosphere cannot be representative of both the \u201cdeuterium-to-hydrogen signal\u201d in the atmosphere and large amounts of water in the past, two mechanisms are in play: both trapping of water in minerals in the planet\u2019s crust and the loss of water to the atmosphere.<\/p>\n

In addition, because Mars has no\u00a0tectonic plates, it cannot recycle water into the atmosphere through volcanism like on\u00a0Earth, making any \u201cdrying\u201d at the surface permanent.\u00a0<\/p>\n

\u201cThe hydrated materials on our own planet are being continually recycled through plate tectonics,\u201d said NASA Mars Exploration Program lead scientist at NASA\u2019s headquarters Michael Meyer. \u201cBecause we have measurements from multiple spacecraft, we can see that Mars doesn\u2019t recycle, and so water is now locked up in the crust or been lost to space.\u201d<\/p>\n

NASA\u2019s Perseverance Mars rover\u00a0has already found signs of water erosion on Mars\u00a0rocks\u00a0during its\u00a0astrobiological\u00a0quest.\u00a0<\/p>\n

A key objective of the rover is to attempt to find signs of ancient microbial life during its mission by collecting and caching both rock and sediment.\u00a0<\/p>\n

Two of the lead authors of this study will aid in the effort\u00a0to collect the samples that will be returned via the Mars Sample Return program\u00a0in the early 2030s<\/a>.<\/p>\n

Meyer, who is part of the\u00a0Mars Sample Return Program, told Fox News<\/a> on Wednesday that they look forward to the continual analysis of their \u201cintriguing results.\u201d\u00a0<\/p>\n

\u201cThe history of water on Mars and its relation to the astrobiological search for habitability and life is one of the biggest questions we continue to study with our missions at the Red Planet,\u201d he said. \u201cThis is ultimately why we hope to collect pristine samples of the Red Planet with the Mars Perseverance rover and safely bring them back to Earth for scientific study through the Mars Sample Return campaign.\u201d\n <\/p><\/div>\n
