This is NASA InSight’s first full selfie on Mars. It displays the lander’s solar panels and deck. On top of the deck are its science instruments, weather sensor booms and UHF antenna. The selfie was taken on Dec. 6, 2018 (sol 10).<\/figcaption><\/figure>\n

Data about Mars\u2019 planetary crust gathered from the Mars InSight lander<\/a> are best explained by the conclusion that the crust has stores of liquid water.<\/p>\n

Analysis led by Vashan Wright, a geophysicist at UC San Diego\u2019s Scripps Institution of Oceanography, provides the best evidence to date that the planet still has liquid water in addition to that frozen at its poles. If that conclusion is true, it sets the stage for new research considering the planet\u2019s habitability and continuing a search for life that exists on a place other than Earth. The potential presence of liquid water on Mars<\/a> has tantalized scientists for decades. Water is essential for a habitable planet.<\/p>\n

\u201cUnderstanding the Martian water cycle is critical for understanding the evolution of the climate, surface, and interior,\u201d Wright said. \u201cA useful starting point is to identify where water is and how much is there.\u201d<\/p>\n

The study appears the week of Aug. 12 in the journal Proceedings of the National Academy of Sciences.<\/em> The Canadian Institute for Advanced Research<\/a>, the National Science Foundation and the US Office of Naval Research supported the work. Besides Wright, study authors are Matthias Morzfeld from Scripps Oceanography and Michael Manga from the University of California Berkeley. <\/p>\n

Wright\u2019s team used data that InSight collected during a four-year mission ending in 2022. The lander collected information from the ground directly beneath it on variables such as the speed of Marsquake waves from which scientists can infer what substances reside beneath the surface.  The data were fed into a model informed by a mathematical theory of rock physics. From it, the researchers determined that the presence of liquid water in the crust most plausibly explained the data.<\/p>\n

\u201cWhile available data are best explained by a water-saturated mid-crust, our results highlight the value of geophysical measurements and better constraints on the mineralogy and composition of Mars\u2019 crust,\u201d the authors wrote. <\/p>\n","protected":false},"excerpt":{"rendered":"
