NASA uploaded a close-up video of Ceres
What are the spots - scientists have yet to find out
None of the spacecraft operating far from the Earth, is not able to shoot video. However, most interplanetary stations take a large number of photos, which can then be compiled to create a video. Recently, just such a video was posted by NASA. On the video - Ceres close-up. Most of the photos were taken by the Dawn at an altitude of 13,600 to 5,100 kilometers.
The video gives an idea of the spatial structure of Ceres. It is worth noting that not so many images are collected here - only 80, in contrast to the same videos of Saturn, composed of thousands of photos transferred to Cassini.
Based on these photos, specialists were able to compose a spatial model of the planetoid. This world, remote from the Earth, has long been a mystery, but now scientists are getting more and more data about the dwarf planet. True, the question of the origin of those same bright spots still remains, although most scientists are inclined to believe that this is the exit of water ice to the surface.
The Dawn probe entered a lower orbit on June 3. The device will spend the rest of the month exploring Ceres at close range (4400 kilometers). All station tools will study the planetoid. Previously, the apparatus was studied by Vesta, another planetoid, from 2011 to 2012. The probe arrived at Ceres on March 6, 2015.
