According to foreign media reports,NASA's curiosity Rover landed on Mars on August 6, 2012, just after celebrating the 3000 day milestone of its scientific life on the red planet.A day on Mars is called sol, which is slightly longer than a day on earth - 24 hours and 39 minutes more.

Scientists track curiosity through solar activity. For example, the original image taken by curiosity is marked with sol number, so the image taken on its anniversary is marked with sol 3000 and the corresponding earth date.

On Tuesday, NASA released a spectacular panorama to mark the special occasion. This image of Mars' Gail crater shows a part of sharp mountain, a huge central mountain in the crater. "Geologists are interested in a series of rock 'benches' seen in the mission's latest panorama," NASA said in a statement

It is reported that this panorama is composed of 122 photos taken by the probe on November 18, 2020, and the time of shooting is Mars sol 2946.

At present, curiosity is going to a crater area called sulfate bearing unit. "Sulfates, like gypsum and Epsom, usually form when water evaporates, and they are another clue to how climate and life prospects changed nearly three billion years ago," NASA said of the curiosity mission.

NASA's only functioning Mars probe will soon welcome its next generation brother, willpower, which is expected to arrive in February. The long-lived curiosity will continue its mission to study the ancient environmental conditions of the red planet.
