Readings from instruments aboard NASA’s Dawn orbiter support the view that a treasure trove of frozen water lies just beneath the surface of the dwarf planet Ceres.
Researchers reported those findings today at the American Geophysical Union’s fall meeting San Francisco, as well as in two papers published by Nature Astronomy and Science.
The findings are based on hydrogen readings from Dawn’s gamma ray and neutron detector, or GRaND, as well as from the spacecraft’s cameras and infrared mapping spectrometer.
