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 ...
The spacecraft entered orbit around Vesta on July 16, 2011, and completed a 14-month survey mission before leaving for Ceres in late 2012. It went into orbit around Ceres on March 6, 2015. Dawn performed near-global geological, chemical, and geophysical mapping of Ceres [8] until its hydrazine fuel was depleted on October 31, 2018.
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. [26]
The Dawn spacecraft has spotted not one, but two bright points on the minor planet Ceres. Newly enhanced images from the probe show two shining spots on the surface. It's not clear exactly what ...
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 ...
Discovered in March 6, 2015 during the early stages of mapping of Ceres's surface, the Dawn mission located a bright region on the Occator crater floor. [ 17 ] [ 18 ] The material in this region was determined to have a dominant composition of sodium (Na) carbonates, aluminium (Al) phyllosilicates, and ammonium chloride (NH 4 Cl).
The crew spent two-and-a-half years training for the Polaris Dawn mission, which included choreographing and rehearsing each step of the spacewalk. Gillis said the flight demonstrated what private ...
It launched on 27 September 2007 as the first space mission to Vesta. On 3 May 2011, Dawn acquired its first targeting image 1.2 million kilometers from Vesta. [105] On 16 July 2011, NASA confirmed that it received telemetry from Dawn indicating that the spacecraft successfully entered Vesta's orbit. [106]
