Sent to survive 700 days on Mars, Curiosity completes 5,000 Martian days

When Nasa's Curiosity rover ticked over its 5,000th sol on August 30, 2026, nobody on Mars was around to see it happen.It was just a rover, alone in the planet's Gale Crater, sending home another set of images like it does most days.A Sol runs about 40 minutes longer than an Earth day, so 5,000 of them adds up to something close to 14 years.What's more significant is that Nasa's Curiosity was originally designed for a mere 2-year-long mission on Mars. It has been 14 years and it's going on strong. An image shows the track marks of Nasa's Curiosity Rover on Mars.

On paper, it sounds like a bad idea, but it worked.Running up that hill!Today, NASA’s Curiosity rover reached the pinnacle — so far — of its 14-year mission on Mars, when it marked an elevation gain of 1 kilometer in its ongoing journey from Gale Crater up the slope of Mount Sharp. 1/2 pic.twitter.com/wZHUrz2PZR— NASA Mars (@NASAMars) August 27, 2026Curiosity was never built for speed or distance the way Nasa's Opportunity Rover was. Its job was to dig into Martian rock and read what the chemistry could tell scientists about the planet's past.It didn't take long to find something.Within its first year, the rover turned up mudstone in Gale Crater that pointed to an ancient lake, evidence that Mars could once have supported microbial life.Ever since, it's been slowly working its way up Mount Sharp, the roughly five-kilometre mountain rising out of the crater floor, reading each layer of rock like pages of a very old book.14 YEARS ON AND COUNTINGJust four days before hitting Sol 5,000, on August 26, 2026, Curiosity crossed another marker. It crosses one full kilometre of elevation gained since it started climbing Mount Sharp back in 2014.As of May 2026, its total distance driven stood at just under 37 kilometres, a fraction of what Opportunity managed, but distance was never really Curiosity's game.
