NASA’s Dawn mission tagged posts

One of the most exciting findings from NASA’s Dawn mission is that Ceres, the largest object in the asteroid belt that lies between Mars and Jupiter, hosts complex organics. The discovery of aliphatic molecules, which consist of carbon and hydrogen chains, in conjunction with evidence that Ceres has abundant water ice and may have been an ocean world, means this dwarf planet might have once harbored the main ingredients associated with life as we know it.

How the aliphatic organics originated on Ceres has been the ...

At the poles of Ceres, scientists have found craters that are permanently in shadow (indicated by blue markings). Such craters are called “cold traps” if they remain below about minus 240 degrees Fahrenheit (minus 151 degrees Celsius). These shadowed craters may have been collecting ice for billions of years because they are so cold. This image was created using data from NASA’s Dawn spacecraft. Credit: NASA/JPL-Caltech/Goddard

Scientists with NASA’s Dawn mission have identified permanently shadowed regions on the dwarf planet Ceres. Most of these areas likely have been cold enough to trap water ice for a billion years, suggesting that ice deposits could exist there now. “The conditions on Ceres are right for accumulating deposits of water ice,” said N Schorghofer...
