Mystery Of Mars’ Lost Atmosphere Solved At Last (Synopsis) [Starts With A Bang]
“Studying whether there’s life on Mars or studying how the universe began, there’s something magical about pushing back the frontiers of knowledge. That’s something that is almost part of being human, and I’m certain that will continue.” -Sally Ride
If you came to the Solar System some 500 million years after its formation, you would’ve found two world with oceans of liquid water, continents and all the conditions we know of for life to begin thriving: Earth and Mars. But unlike our own world, Mars’ organic history was cut short when it lost its atmosphere and became a barren, desert wasteland.

While we had some pretty compelling theories as to how this happened, it was only with the advent of the Maven mission and its first science results that we discovered exactly how, how fast and when Mars lost its atmosphere. One cool discovery: aurorae appear diffuse and all over the entire night sky on Mars!
