Happy New Mars Year! The Planetary Society

They’re too far apart to have a party, but today Curiosity and Opportunity could have rung in the New Mars Year. Today Mars reached a solar longitude of zero degrees and the Sun crossed Mars’ equator, heralding the arrival of spring in the northern hemisphere and autumn in the southern hemisphere. This is the date that Martian climatologists have identified as the zero-point for Mars’ calendar. Mars Year 31 was a good one, with Opportunity active at the rim of Endeavour crater and Curiosity arriving at Gale. Mars Year 32 should be even better, as Opportunity rolls up Solander point and maybe even Cape Tribulation, and Curiosity should explore the rocks in the mountain that drew her to Gale in the first place. And there’ll be two orbiters arriving (we hope). MAVEN and the Mars Orbiter Mission’s capabilities should warm the hearts of the climatologists who care about how one Mars year differs from the next enough to need to make up a calendar to mark their passage!
