NASA has released an update summarizing what scientists have found since Dawn went into orbit around Vesta in July. The video below, compiled from images Dawn has taken, gives a nice visual overview. The most interesting big feature, understated by the video, is the series of grooves that appear to encircle the asteroid’s equator. To my eye it almost looks like Vesta was once two asteroids that got merged into one, with these grooves indicating the weld point.
In the last week there has been a flurry of avalanches and rockfalls at Mt. Rainier. On June 25 two climbers had cameras rolling when a major rockfall started on Nisqually Glacier. Below is the better of the two videos.
