Dawn is a retired space probe that was launched by NASA in September 2007 with the mission of studying two of the three known protoplanets of the asteroid belt: Vesta and Ceres. [1] In the fulfillment of that mission—the ninth in NASA's Discovery Program — Dawn entered orbit around Vesta on July 16, 2011, and completed a 14-month survey ...
Achita is a large impact crater on the dwarf planet Ceres. The crater is named after Achita, a Nigerian god of agriculture. The crater was imaged as part of NASA's Dawn mission. [2] The probe showed that Achita has mass-wasting ridges on the floor [3] and is the fourth oldest crater on Ceres having been formed 570 million years ago. [4]
The mountain was discovered on images taken by the Dawn spacecraft in orbit around Ceres in 2015. [6] It is estimated to have an average height of about 4 km (2.5 mi; 13,000 ft) and a maximum height of about 5 km (3.1 mi; 16,000 ft) on its steepest side; it is about 20 km (12 mi; 66,000 ft) wide at the base.
It was only just yesterday that NASA announced its Kepler space telescope had officially been declared dead, and now there's another long-running mission that has also met its demise. Today, NASA ...
We'll soon know a lot more about it as NASA's Dawn spacecraft has nearly reached Ceres. It's already captured shots of the planet (above) and will soon go into a polar orbit at 13,500 km (8,300 ...
NASA's Dawn mission is a mission in NASA's Discovery Program. Dawn orbited and explored the giant protoplanet Vesta in 2011-2012, and now it is in orbit and exploring a second new world, dwarf ...
Dawn 's images led to widespread reports in the media about the bright spots, including in news sources, [22] astronomy magazines, [23] and science magazines. [24] An informal NASA poll during May offered the following ideas for the nature of the spots: [ 25 ] ice, volcanos, geysers, salt deposits, rock, or other.
Ceres imaged by the Dawn spacecraft in 2015. The bright spot in the upper-left area is Occater crater. Ceres Polar Lander (CPL) is a European mission concept for a lander to Ceres that would search for biosignatures. [1] Published in 2008, the concept calls for a low-cost mission using reliable existing technology to complement other larger ...
