“We needed a historic dust storm to finish this historic mission,” said deputy project scientist Abigail Fraeman of JPL.

The rover will now experience the deep freeze of a Martian winter, with temperatures too cold for Opportunity to survive without electrical help from its solar panels. There were hugs,” tweeted Tanya Harrison, a Mars scientist at Arizona State University in Tempe.

"We know the bottom layers of the mountain were buried over time. But this finding suggests they weren't buried by as much material as we thought." Making Mount Sharp Planetary scientists have long debated the origin of Mount Sharp.

Mars craters the size of Gale have central peaks raised by the shock of the impact that made the crater. But the upper layers of the mound appear to be made of wind-scoured sediments more easily eroded than rock.

Emotions ran high at mission control on the evening of the final contact attempt. Launched in July 2003, Opportunity landed in Meridiani Planum in January 2004 to carry out a 90-day mission of exploration.

It ultimately discovered the most ancient habitable environment on Mars.The rover’s twin, Spirit, became mired in sand in Gusev Crater, on the other side of the planet, in 2009. NASA’s Curiosity rover, which landed in 2012 and is nuclear-powered, continues to explore Mars, in Gale Crater.Three more rovers — one each from NASA, the European Space Agency and the China National Space Administration — are expected to launch in 2020, the next time that Earth and Mars will be favourably aligned for spacecraft launches.Meanwhile, NASA’s newest Mars lander is just getting to work, near the equator and not too far from Curiosity.The stationary In Sight probe arrived in November and deployed its French-built seismometer in December, then its German-built heat probe on 12 February.
