Even then, engineers were sending final software updates to the rovers while they were in space and en route to Mars. Hardware and software were being tested in three eight-hour shifts, 24 hours a day, seven days a week.
JPL deputy project manager Jennifer Trosper, brought on to lead the systems engineering, recalls the effort as an all-hands-on-deck experience.

Teams led by project manager Peter Theisinger huddled to figure out how to pull off the build. “The schedule that we faced to try to do something that had never been done before was just brutal.” “People will say to me, It's a miracle it’s lasted so long, and I want to say, It’s a miracle we even got to Florida!” Squyres says, referencing the rover's launch site at Cape Canaveral. Here, JPL was trying to pack all the features of a lander into a rover, with far greater autonomy than Pathfinder ever had. The rovers' most direct ancestor, the Pathfinder mission, consisted of a lander and separate rover. But elation soon gave way to panic: The team had hoped for at least 48 months to build the two rovers, but they would get only 34.Īnd as the team raced against this deadline, engineers were also trying to reinvent how rovers are built in the first place. The mission's core team spent more than a decade writing unsuccessful proposals to NASA, until the agency finally approved a two-rover mission by early 2000. Opportunity's path to Mars was as uneven as the red planet's rolling hills. To have Opportunity go for 14-and-a-half years and then get taken out by one of the most ferocious Mars dust storms in decades-if that's the way it plays out, we can walk away with our heads held high.” "Miracle" mission to Mars The other is Mars just finally reaches out and kills them. “One is simply that we wear the vehicles out. “I always felt that were really two honorable ways for a mission like this to end,” adds Cornell planetary scientist Steve Squyres, the mission's longtime principal investigator. And I look forward to congratulating the team that puts Opportunity into second place.” ( See amazing pictures from 20 years of nonstop rovers on Mars.) “I am looking forward to the future when Opportunity's records fall, because that will mean that we continue to explore our solar system.

“It was one heck of a mission, wasn't it?” Mike Seibert, a former driver of Opportunity, says in an email. Meanwhile, Opportunity went farther for longer than any other vehicle on another world-and all other Mars rovers combined. After landing on January 4, 2004, Spirit drove hard through rugged terrain until it got stuck in 2009 and went silent in 2010. But the pair surpassed every conceivable expectation. The two rovers were each designed to go less than a mile and last 90 to a hundred Martian days, or sols. The announcement marks the end of the record-smashing Mars Exploration Rovers mission, which built and operated Opportunity and its sibling rover, Spirit. But when “rover cleaning” season came and went without signals from Opportunity, hopes that it had survived began to dim. From about November to January, the red planet saw seasonal winds strong enough to wipe accumulated dust from Opportunity's solar panels, which is one of the major reasons the rover lasted so long in the first place. Initially, the storm didn't give the team pause. NASA had not heard from the rover since June 2018, when one of the most severe dust storms ever observed on Mars blotted out much of the red planet's sky and overtook the solar-powered rover. “I think it'll be a long time before any mission surpasses what we were able to do.” But at the same time, we have to remember this phenomenal accomplishment-this historic exploration we've done,” says John Callas, the project manager for the Mars Exploration Rovers mission. “With this mission, more than other robotic missions, we have made that human bond, so saying goodbye is a lot harder. In its record-breaking time on Mars, the rover drove more than 28 miles, finding some of the first definitive signs of past liquid water on the red planet's surface. After more than 14 years driving across the surface of Mars, the NASA rover Opportunity has fallen silent-marking the end of a defining mission to another world.Īt a press conference at the Jet Propulsion Laboratory in Pasadena, California, NASA bid farewell to the rover it placed on Mars on January 25, 2004: before Facebook, before the iPhone, and even before some of the scientists now in charge of it graduated high school.
