NASA rover finally bites the dust
NASA’s Opportunity, the Mars rover that was built to operate for just three months but kept going and going, rolling across the rocky red soil, was pronounced dead Wednesday, 15 years after it landed on the planet.
The six-wheeled vehicle that helped gather critical evidence that ancient Mars might have been hospitable to life was remarkably spry up until eight months ago, when it was finally doomed by a ferocious dust storm.
Flight controllers tried numerous times to make contact, and sent one final series of recovery commands Tuesday night, along with one last wake-up song, Billie Holiday’s “I’ll Be Seeing You,” in a sombre exercise that brought tears to team members’ eyes. There was no response from space, only silence.
Thomas Zurbuchen, head of NASA’s science missions, broke the news at what amounted to a funeral at the space agency’s Jet Propulsion Laboratory in Pasadena, California, announcing the demise of “our beloved Opportunity.”
“This is a hard day,” project manager John Callas said at an auditorium packed with hundreds of current and former members of the team that oversaw Opportunity and its long-deceased identical twin, Spirit. “Even though it’s a machine and we’re saying goodbye, it’s still very hard and very poignant, but we had to do that. We came to that point.”
The two slow-moving, golf cart-size rovers landed on opposite sides of the planet in 2004 for a mission meant to last 90 sols, or Mars days, which are 39 minutes longer than Earth days.
In the end, Opportunity outlived its twin by eight years and set endurance and distance records that could stand for decades. Trundling along until communication ceased last June, Opportunity roamed a record 28 miles and worked longer than any other lander in the history of space exploration.
Opportunity was a robotic geologist, equipped with cameras and instruments at the end of a mechanical arm for analyzing rocks and soil.
