Both small worlds reside in the debris-strewn main asteroid belt between Mars and Jupiter. Dawn also found hydrated and carbon rich material on its surface supplied by impactors, a result that was unexpected based on pre-Dawn telescopic observations. Vesta and Ceres are the two most massive bodies in the main asteroid belt between Mars and Jupiter. NASA's Dawn mission has found that craters on Ceres show a diversity of shapes that provide important clues about the structure of Ceres' subsurface; shown here is Fejokoo, a polygonal crater. Dawn (« Aube » en anglais) est une sonde spatiale de la NASA, dont la mission consiste à étudier Vesta et Cérès, les deux principaux corps de la ceinture d'astéroïdes.Lancée en 2007, Dawn a entamé ses observations en 2011, en se plaçant en orbite autour de Vesta, puis de Cérès, et les a achevées en 2018. Orbital ATK Inc., in Dulles, Virginia, designed and built the spacecraft. Fejokoo Crater This image has not been validated or calibrated.
Dawn missed scheduled communications sessions with NASA's Deep Space Networkon Wednesday, Oct. 31, and Thursday, Nov. 1, 2018. A validated/calibrated image will be archived with the NASA Planetary Data System in 2012. These diverse worlds offer scientific snapshots of the early solar system. JPL is responsible for overall Dawn mission science.

The mission featured extended stays at two very different extraterrestrial bodies: giant asteroid Vesta and dwarf planet Ceres. The Delta II was designed to boost medium-sized satellites and robotic explorers into space. Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. The mission featured extended stays at two very different extraterrestrial bodies: giant asteroid Vesta and dwarf planet Ceres. Dawn orbited the protoplanet Vesta and is now in orbit around the dwarf planet Ceres as part of its mission to characterize the conditions and processes that shaped our solar system. Overview One Mission, Two Remarkable Destinations. Dawn was a mission to the two most massive bodies in the main asteroid belt – Vesta and Ceres. This image of Ceres is part of a sequence taken by NASA's Dawn spacecraft April 24 to 26, 2015, from a distance of 8,500 miles (13,500 kilometers).
This view from NASA's Dawn spacecraft taken on May 29, 2016, shows terrain on Ceres centered at approximately 41 degrees north latitude, 308 degrees east longitude. Dawn is a project of the directorate's Discovery Program, managed by NASA's Marshall Space Flight Center in Huntsville, Alabama.
