Martian Crater
-
The May calendar image of a Martian crater with icy blue frost near the rim was taken by the MRO (Mars Reconnaisance Orbiter), which has beamed back images of the surface of Mars since 2006. MRO's scientific discoveries have both confirmed and upended what we previsouly could only speculate about the red planet.

New Year, New Mars: Red Planet Gets Active as Spring Begins
Mars scientists have recently marked a new year on the Red Planet, a milestone that occurs every 687 days. Because the Martian new year coincides with spring in the planet’s northern hemisphere, it’s a time of lots of activity — avalanches, exploding jets of gas, and more. JPL research scientist Serina Diniega explains some of the changes to the Martian surface that scientists can track with spacecraft like NASA’s Mars Reconnaissance Orbiter (MRO).
