The original question was how did Mars lose its atmosphere. I think that what happened is likely on the lines of: 1) Less iron on Mars sank to the core. Mars is enriched in surface iron.2) Photo-disassociation of water left Mars oxygen rich.3) This rusted the iron.4) Lightning react...
How Mars is losing its atmosphereThe rover will continue to study the local environment in the Gale Crater during April, before new instructions are beamed from Earth after the passing of the Mars solar conjunction, which partially blocks Mars from the Earth.Steve Down...
In one paper, Bruce Jakosky of the University of Colorado Boulder and his colleagues report MAVEN data showing that when protons and electrons from a solar eruption slammed into the planet in March 2015, they increased the rate at which Mars loses its atmosphere by roughly an order of ...
(Phys.org) —New findings from NASA's Curiosity rover provide clues to how Mars lost its original atmosphere, which scientists believe was much thicker than the one left today. "The beauty of these measurements lies in the fact that these are the first really high-precision measurements of th...
A key tracer used to estimate how much atmosphere Mars lost can change depending on the time of day and the surface temperature on the Red Planet, according to new observations by NASA-funded scientists. Previous measurements of this tracer—isotopes of

How Mars died? Mars may once have been more hospitable to life than it is now. Scientists think the magnetosphere of Mars collapsed around 3.7 billion years ago, and it eventually lost its atmosphere. Now, Mars has a very thin atmosphere: the atmospheric pressure on the Martian surface averag...
Without it, these charged particles (and cosmic rays which originate from the sun, from outside of the solar system, or even from distant galaxies) would strip away the upper atmosphere. And, gradually, in a few billion years, our planet would lose its atmosphere, like today’s Mars....
(The NASA spacecraft Maven is already examining the Martian atmosphere and helping scientists decipher how Mars lost its water, if that did happen, he said.) The new finding gives researchers a good spot to look for life on Mars, Zurek said. But the newfound salty streaks aren't like ...
Those gardening skills will be important for long interplanetary space voyages, such as a trip to Mars. Orbiting above the Earth's atmosphere and equipped with special instruments and telescopes, the ISS crew can monitor lots of different things on the planet's surface (like glacier distribution ...
