NASA scientists used the data from DAWN to create a computer model of Vesta's surface. The model reveals two giant craters in the southern hemisphere, with cliffs, grooves, and surface lineaments (linear features).
By analyzing all the craters on Vesta, scientists estimate that these two craters are the result of collisions 1 and 2 billion years ago (and not 4.5 billion years ago, as originally thought). The more recent of these collisions raised a central peak more than twice as high as Mount Everest.
