Opportunity cleared dozens more rock's surfaces for measurements using its spectrometers and a microscopic imager. Scientists at NASA's Jet Propulsion Laboratory declared the spacecraft dead after their latest attempt to revive the rover failed.
"Mars is now part of our neighbourhood".
NASA's beloved Mars rover, Opportunity, has been officially laid to rest more than seven months after it was engulfed by a enormous dust storm and fell silent. The last attempt was made on Tuesday night.

Then last June, a thick dust storm clouded the martian atmosphere, sharply reducing the sunlight reaching the rover's solar panels.
"I declare the Opportunity mission as complete", Thomas Zurbuchen, associate administrator of Nasa's Science Mission Directorate told a news conference at mission headquarters in Pasadena, California. But, you know, I have to sit back and reflect that this mission has been going on for 15 years.
U.S. space agency NASA is to hold a briefing today at United Kingdom time 7 pm, in which it is to officially announce the Mars Opportunity Rover mission "dead". "Even though it's a machine and we're saying goodbye, it's very hard and very poignant". The agency will have made one final attempt to contact Opportunity Rover late last night US time (Tuesday), eight months after the spacecraft last made contact. It went to Mars to study the Red Planet's geology. Goodnight, rover. You've served us better than we could ever have hoped for.
Knicks delete Durant photo from ticket pitch on website
The Knicks said in a statement to the New York Daily News the image was one of "several rotating photos on the website". First Durant snapped at media members for asking him about free agency, then the Knicks dug the issue back up.
Following a Twitter campaign using the hashtag #SaveOppy, NASA announced on October 29, 2018, that it would continue its active listening phase. By February 6, NASA reported that more than 835 recovery commands had been sent to the rover over a span of frequencies, including those outside its normal communications range.
It was built in just 90 days but went on to live for 14 years.
The pair have had their share of incidents.
Both rovers bounced to the Martian surface, wrapped in protective airbags, in January 2004. Like its sister craft, Spirit outperformed its intended 90-day mission, returning science for almost six years before becoming permanently stuck by a rock. And in the years before its demise, it had been forced to drive backward, when a wheel stopped working in 2006.
"Engulfed by a giant planet-encircling dust storm: Is there a more fitting end for a mission as flawless and courageous from start to finish as Opportunity?" he said. "Water on Mars!' It was really sulfuric acid on Mars, right?" he said, half-jokingly. "It was a world that was more Earthlike". JPL's director, Michael Watkins, said Opportunity and Spirit created a "new paradigm for solar system exploration".
That paradigm is having a robotic rover that not only takes images of a planet, but one that can also function as a planetary geologist, with the ability to drill, take samples and more.
Of 43 missions launched toward Mars, only 18 have made it intact, a success rate of around 40 percent. Like its counterparts, that rover will be fitted with various instruments. This will determine Mars' subsurface temperature and thermal conductivity. On the surface, there's Curiosity and the recently arrived Mars InSight, which will dig underground on Mars in search of seismic activity.
