A new study from NASA's Jet Propulsion Laboratory and researchers at the California Institute of Technology questions whether or not a longheld theory about Mars still holds water. The data pertained to meteorite lab work as well as NASA Mars Exploration Program missions and the team focused on the quantity of water on Mars over time and the chemical composition of the planet's current atmosphere. WHAT THE PERSEVERANCE MARS ROVER HAS ACCOMPLISHED SO FARIn addition, because Mars has no tectonic plates, it cannot recycle water into the atmosphere through volcanism like on Earth, making any "drying" at the surface permanent. "The hydrated materials on our own planet are being continually recycled through plate tectonics," said NASA Mars Exploration Program lead scientist at NASA's headquarters Michael Meyer. NASA's Perseverance Mars rover has already found signs of water erosion on Mars rocks during its astrobiological quest.
