NASA Discovers Further Evidence of Dry Ice Gullies on Mars

A new study details further evidence of dry ice gullies on Mars, revealing that the gullies on Mars’ surface are primarily formed by the seasonal freezing of carbon dioxide, not liquid water. Repeated high-resolution observations made by NASA’s Mars Reconnaissance Orbiter (MRO) indicate the gullies on Mars’ surface are primarily formed by the seasonal freezing […]

Meteorites Provide Clues to Early Atmosphere of Mars

Using data from meteorites that fell to Earth from Mars, scientists investigate the chemical composition of the Martian atmosphere throughout history, and learn whether the planet has ever been hospitable to life. Geologists who analyzed 40 meteorites that fell to Earth from Mars unlocked secrets of the Martian atmosphere hidden in the chemical signatures of […]

Study Shows Gusev Crater on Mars Had a Lake

New research from Arizona State University shows evidence that the Gusev Crater on Mars once held a lake. If desert mirages occur on Mars, “Lake Gusev” belongs among them. This come-and-go body of ancient water has come and gone more than once, at least in the eyes of Mars scientists. Now, however, it’s finally shifting […]
