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 Dawn mission is managed by NASA's Jet Propulsion Laboratory. [101] Dawn is the first spacecraft to visit either Vesta or Ceres. It is also the first spacecraft to orbit two separate extraterrestrial bodies, using ion thrusters to travel between its targets.
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.
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 ...
The Deep Space 1 and Dawn used the NSTAR, a solar-powered electrostatic ion propulsion engine. The NASA Solar Technology Application Readiness (NSTAR) is a type of spacecraft ion thruster called electrostatic ion thruster. [1] [2] It is a highly efficient low-thrust spacecraft propulsion running on electrical power generated by solar arrays.
Occator / ɒ ˈ k eɪ t ər / is an impact crater located on Ceres, the largest object in the main asteroid belt that lies between the orbits of Mars and Jupiter, that contains "Spot 5", the brightest of the bright spots observed by the Dawn spacecraft. It was known as "Region A" in ground-based images taken by the W. M. Keck Observatory on ...
NASA's Dawn Spacecraft has photographed a pyramid-like mountain that rises nearly three miles above the planet's surface. How the peak was created remains a mystery, but there are some interesting ...
