NASAhas finally plugged the plug on itsMarsOpportunity rover, which has been silent on the Red Planet’s surface for eight months.
“I declare the Opportunity mission is complete,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate during a press conference on Wednesday. “I have to tell you, this is an emotional time,” he added.
The rover reached Mars in 2004, but NASA lost contact with the vehicle last year following an epic dust storm that enveloped the red planet and prevented sunlight from reaching its surface. The last signal received from the $400 million solar-poweredroverwas on June 10, 2018.
NASA made itslast planned attemptsto communicate with Opportunity late on Tuesday, but did not receive any response back. “I heard this morning that we had not heard back,” said Zurbuchen, explaining that the “beloved” rover remains silent.
The missing vehicle wasspottedthree months later. On Sept. 20, the HiRISE high-resolution camera on NASA’s Mars Reconnaissance Orbiter captured an image of the rover in Mars’ Perseverance Valley. However, scientists were still unable to talk to the vehicle.
Opportunity landed on Mars on Jan. 24, 2004 PST, just three weeks after its identical twin, Spirit, reached the Red Planet’s surface.
Both outlived and outperformed expectations, on opposite sides of Mars. The golf-cart-sized rovers were designed to operate as geologists for just three months, after bouncing onto our planetary neighbor inside cushioning airbags. They rocketed from Cape Canaveral a month apart in 2003. Spirit was pronounced dead in 2011 a year after it got stuck in sand and communication ceased.
“This is a celebration of so many achievements,” said NASA Administrator Jim Bridenstine, during Wednesday’s press conference at the agency’s Jet Propulsion Laboratory in Pasadena, California.
Opportunity set records on the Red Planet. Rolling along until communication ceased last June, Opportunity roamed a record 28 miles around Mars and worked longer than any other lander.
Its greatest achievement was discovering, along with Spirit, evidence that ancient Mars had water flowing on its surface and might have been capable of sustaining microbial life.
Contact with Opportunity was lost during the fiercest Martian dust storm in decades. The storm was so intense that it darkened the sky for months, preventing sunlight from reaching the rover’s solar panels.
The storm may have scrambled the rover’s internal clock, NASA explained on Wednesday, meaning that the rover would not know when to sleep, wake up, or receive commands.
NASA has two other probes operating on Mars. The Curiosity rover, which reached the Red Planet in August 2012, has more than 12 miles on its odometer. NASA’s Insight Mars Lander reached the surface of the Red Planet in November 2018, ending a journey that lasted six months and more than 300 million miles.
In November 2018, NASA announced that it has selected the location where its Mars 2020 rover will land on the Red Planet. The rover is expected to land on Mars Feb. 18, 2021.
