MARS Atmosphere & Volatile Evolution (Artificial satellite)SOLAR flaresThe article summarizes research published in two issues of "Science" and in a 2015 issue of "Geophysical Research Letters" concerning results form the U.S. National Aeronautics and Space Administration's MAVEN spacecraft which ...
(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 oxygen—have disagreed significantly. An acc...

Beyond logistics and cost are all the vast unknowns about how the human system could react to an atmosphere like Mars. Because Mars has no magnetic field, humans would receive whopping doses of cosmic radiation — not a problem on Earth, where the planet's magnetic field works to block it...

formed with the rest of the solar systemabout 4.6 billion years ago. Around 3.8 billion years ago, thesame time that life formed on Earth, early Mars was very Earth-like. It hadabundant liquid wateron its surface in the form of oceans, lakes and rivers and possessed a denser atmosphere....
“Pursuing two potential paths forward will ensure that NASA is able to bring these samples back from Mars with significant cost and schedule saving compared to the previous plan,” said NASA Administrator Bill Nelson. “These samples have the potential to change the way we understand Mars, our...
"How gold, orange, or red the moon appears during a total lunar eclipse depends on how much dust, water, and other particles are in Earth's atmosphere"according to NASA scientists. Other atmospheric factors such as temperature and humidity also affect the moon's appearance during a lunar ecli...
And scientists see that deforestation has a significant effect on climate change, or global warming. At-a-glance: Deforestation Facts and Figures Africa and South America suffer the largest loss of forest worldwide. Tropical rainforests are home to more than half of all species on the planet. ...
