Dawn Data Provide New Evidence for Ground Ice on Asteroid Vesta

Sep 22, 2017 by News Staff

Using data from NASA’s Dawn spacecraft, researchers have found new evidence for the occurrence of ground ice on Vesta, the second largest asteroid of...

Oxo Crater is the second-brightest feature on Ceres. Only Occator’s central area is brighter. Oxo lies near the 0 degree meridian that defines the edge of many Ceres maps, making this small feature easy to overlook. NASA’s Dawn spacecraft took this image in its low-altitude mapping orbit, at a distance of 385 km from the surface of Ceres. Image credit: NASA / JPL-Caltech / UCLA / MPS / DLR / IDA / PSI.

With a diameter of 57 miles (92 km), Occator crater is larger than Tycho crater on the Moon. Its steep walls stand tall at over 1.4 miles (2 km), higher than the North face of the Eiger in the Bernese Alps. The origin and nature of the bright spots in its interior is still not clear.

This enhanced color composite image, made with data from NASA’s Dawn spacecraft, shows the area around Ernutet crater, which is about 32 miles (52 km) in diameter and is located in the northern hemisphere. The bright red portions appear redder with respect to the rest of Ceres. In the new study, planetary researchers found that these red areas around Ernutet are associated with evidence of organic material. Images taken using blue (440 nm), green (750 nm) and infrared (960 nm) spectral filters were combined to create the view. Image credit: NASA / JPL-Caltech / UCLA / MPS / DLR / IDA.

Ahuna Mons, Ceres’ lonely mountain, is seen in this simulated perspective view. The elevation has been exaggerated by a factor of two. The view was made using enhanced-color images from NASA’s Dawn orbiter. Images taken using blue (440 nm), green (750 nm) and infrared (960 nm) spectral filters were combined to create the view. The spacecraft’s framing camera took the images from Dawn’s low-altitude mapping orbit, from an altitude of 240 miles (385 km) in August 2016.
