The Dawn spacecraft has almost reached the dwarf planet Ceres, and a lot more detail can be seen as it gets closer. The odd bright spots which have puzzled scientists for a long time now can also be seen more clearly for the first time. What was thought to be one spot in this crater is now obviously two close together. Are they exposed ice or some other material? Are they related to possible cryovolcanoes? Dawn was 46,000 kilometers (29,000 miles) away when it took this image on February 18, 2015.
Dawn will arrive at Ceres on March 6, and we will then have the first close-up images of this still-unexplored world. There will also be a NASA press conference tomorrow, March 2 at 9:00 am PT (12:00 pm ET) to discuss the arrival of Dawn at Ceres.
