This view of sample site Osprey on asteroid Bennu is a mosaic of images collected by NASA's OSIRIS-REx spacecraft on May 26. A total of 347 PolyCam images were stitched together and corrected to produce the mosaic, which shows the site at 0.2 inches (5 mm) per pixel at full size. The spacecraft took these images during an 820-foot (250-meter) reconnaissance pass over the site, which is the closest Osprey has been imaged. The pass was designed to provide high-resolution imagery to identify the best areas within the site to collect a sample. The sample site is located in the crater at the bottom of the image, just above the dark patch at the crater's center. The long, light-colored boulder to the left of the dark patch, named Strix Saxum, is 17 ft (5.2 m) in length. The mosaic is rotated so that Bennu's east is at the top of the image. Osprey is the backup sample collection site for the OSIRIS-REx mission. OSIRIS-REx is scheduled to make its first sample collection attempt at primary site Nightingale on Oct. 20.
Asteroids Bennu and Ryugu may have formed directly from collision in space Tucson AZ (SPX) Jun 02, 2020 Scientists with NASA's first asteroid sample return mission, OSIRIS-REx, are gaining a new understanding of asteroid Bennu's carbon-rich material and signature "spinning-top" shape. The team, led by the University of Arizona, has discovered that the asteroid's shape and hydration levels provide clues to the origins and histories of this and other small bodies. Bennu, the target asteroid for the OSIRIS-REx mission, and Ryugu, the target of the Japan Aerospace Exploration Agency's Hayabusa2 asteroid ... read more
