In addition to exceeding its life expectancy by 60 times, the rover travelled more than 28 miles by the time it reached its final resting spot on Mars - Perseverance Valley. "I heard this morning that we had not heard back", said Zurbuchen, explaining that the "beloved" rover remains silent.
United States space agency NASA is to hold a briefing today at 7 pm GMT (2 pm ET), in which it is to officially announce the Mars Opportunity Rover mission "dead".
This is the last image the rover's panoramic camera captured before the rover communicated to engineers that its power was running low and that the dusty conditions were making things quite dark. However, scientists were still unable to talk to the vehicle.

Both outlived and outperformed expectations, on opposite sides of Mars.
Its identical twin, Spirit, was pronounced dead in 2011, a year after it got stuck in sand and communication ceased. The golf cart-size rovers were created to operate as geologists for just three months, after bouncing onto our planetary neighbor inside cushioning air bags in January 2004.
Besides endurance, the six-wheeled rover set a roaming record of 45 kilometres.
They were rocketed from Cape Canaveral a month apart in 2003.

"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.
During the second part of its life on Mars, Opportunity climbed to the edge of the crater Endeavour, taking spectacular panoramic images - and discovering veins of gypsum, additional proof that water once flowed among the Martian rocks.
NASA's InSight lander is to place the heat flow probe on the Martian surface to take the temperature of the inside, according to the mission team.
Today, only a single rover is still active on Mars, Curiosity, which arrived in 2012.
In 2021, the recently named Rosalind Franklin robot, part of the European-Russian ExoMars mission, is slated to land on a different part of the planet, raising the population of active rovers to two.More news: Tottenham boss not surprised by Jadon Sancho's heroics at Borussia Dortmund
