OSIRIS-REx finds rugged terrain on asteroid Bennu
NASA’s OSIRIS-REx spacecraft’s navigation camera captured this image of asteroid Bennu on Jan. 17 from a distance of approximately 1 mile (1.6 kilometers). The large boulder in partial shadow at the lower right of the frame is about 165 feet (50 meters) across.

OSIRIS-REx completes New Year’s Eve orbit insertion burn at asteroid
This mosaic image of asteroid Bennu is composed of 12 PolyCam images collected on Dec. 2 by the OSIRIS-REx spacecraft from a range of 15 miles (24 kilometers). Credits: NASA/Goddard/University of Arizona After four weeks of navigating in the vicinity of asteroid Bennu, NASA’s OSIRIS-REx spacecraft fired its thrusters for eight seconds Monday to slip into…

Scientists suggest streaks on Martian hillsides are dry flows
This inner slope of a Martian crater has several of the seasonal dark streaks called “recurrent slope lineae,” or RSL, that a November 2017 report interprets as granular flows, rather than darkening due to flowing water. The image is from the HiRISE camera on NASA’s Mars Reconnaissance Orbiter. Credits: NASA/JPL-Caltech/UA/USGS Intermittent flows that appear on…

Asteroid-bound probe returns Earth-moon family portrait
The MapCam camera on the OSIRIS-REx spacecraft took this picture of the Earth and the moon Oct. 2 at a distance of around 3.2 million miles (5.1 million kilometers) from Earth. Credit: NASA/Goddard/University of Arizona Ten days after a swingby to receive a gravitational boost toward its asteroid target, NASA’s OSIRIS-REx spacecraft turned one of…

Planet Earth observed through telescope orbiting Mars
Here is a view of Earth and its moon, as seen from Mars. It combines two images acquired on Nov. 20, 2016, by the HiRISE camera on NASA’s Mars Reconnaissance Orbiter, with brightness adjusted separately for Earth and the moon to show details on both bodies. Relative sizes and distance are correct. Credit: NASA/JPL-Caltech/University of…

Assembly complete for NASA’s asteroid sample return spacecraft
Technicians recently installed OSIRIS-REx’s solar panels and high-gain antenna. Credit: Lockheed Martin NASA’s first asteroid-sampling probe, OSIRIS-REx, has been assembled at a Lockheed Martin satellite factory in Colorado and is now being tested to ensure it can withstand the harsh journey to an asteroid and back. The OSIRIS-REx spacecraft is now set for a sequence…
