An anonymous reader writes "NASA's Mars rovers have been on the red planet for five years now. The rovers were originally planned to stay operational on the planet for only 90 days, but it has turned into a much longer mission than anticipated. NASA has put together a video to celebrate the anniversary. The rovers have made important discoveries about wet and violent environments on ancient Mars. They also have returned a quarter-million images, driven more than 21 kilometers (13 miles), climbed a mountain, descended into craters, struggled with sand traps and aging hardware, survived dust storms, and relayed more than 36 gigabytes of data via NASA's Mars Odyssey orbiter. To date, the rovers remain operational for new campaigns the team has planned for them."
