NASA\u2019s Mars Odyssey spacecraft has been operating for so long, it can rent a car without any fees. The spacecraft arrived at the Red Planet<\/a> on October 24, 2001. It, along with its 20-year-old sibling, the Mars Reconnaissance Orbiter (MRO), have operated longer than anyone watching their launches could have dreamed possible.<\/p>\n

Having such a long record of observations<\/a> from above the Martian surface has rewritten the story of water on the planet<\/a>, past and present alike. Keeping the wizened orbiters going for so long has been possible only thanks to great engineering and constant problem solving\u2014and a little luck. But scientists wonder whether, despite their storied legacies<\/a>, Odyssey and MRO will be the last of their kind, at least for the Red Planet.<\/p>\n

\u201cBoth Odyssey and MRO are some of the most productive spacecraft that have ever existed,\u201d says Briony Horgan, a planetary scientist at Purdue University who isn\u2019t affiliated with either mission, calling them \u201ccritical\u201d to NASA\u2019s overall Mars research program. Odyssey\u2019s observations of the planet\u2019s ice, for example, and MRO\u2019s ability to see surface features change over time have each given scientists unprecedented insight into Mars as a vibrant planet rather than a lump of rock. Odyssey and MRO also connect humans to every NASA rover<\/a>, which can\u2019t communicate with Earth directly. It\u2019s an impressive legacy for a pair of orbiters that were only meant to last just a few years.<\/p>\n

Space is a notoriously harsh environment that takes luck and resilience to survive for decades. Particularly tricky is the barrage of high-energy particles hitting machinery; a powerful enough strike to a delicate enough apparatus can be fatal. And whereas engineers can keep constant tabs on satellites orbiting Earth, bandwidth to Mars is more limited\u2014science spacecraft might only check in once or twice a week, says Rob Lillis, a planetary and space physicist at the University of California, Berkeley, who has worked on a range of more recent Mars orbiters.<\/p>\n

\u201cA Mars craft has to be able to manage by itself,\u201d he says.<\/p>\n
