Significant changes in Mars' atmosphere detected
NASA said today that new data from the Mars Reconnaissance Orbiter (MRO) has demonstrated that the amount of atmosphere on the Red Planet depends entirely on the tilt of its axis. This is significant, the space agency said, because that axis tilt may well impact the stability of any liquid water that exists on Mars, as well as the frequency and strength of dust storms.
In a release, NASA explained that by employing the MRO's ground-penetrating radar, researchers were able to identify a massive subsurface deposit of frozen carbon dioxide--dry ice--on Mars' southern pole. "The scientists suspect that … Read more
