New data from two instruments on NASA’s OSIRIS-REx spacecraft — the OSIRIS-REx Visible and Infrared Spectrometer (OVIRS) and the OSIRIS-REx Thermal Emissions Spectrometer (OTES) — reveal the presence of hydroxyls, molecules that contain oxygen and hydrogen atoms bonded together, on the surface of asteroid Bennu. According to the mission science team, these hydroxyl groups may exist globally across the asteroid in hydrated clay minerals,...

This image from InSight’s robotic-arm mounted Instrument Deployment Camera shows the instruments on the spacecraft’s deck, with the Martian surface of Elysium Planitia in the background. The color-calibrated picture was acquired on December 4, 2018 (Sol 8); in the foreground, a copper-colored hexagonal cover protects the SEIS seismometer; the gray dome behind SEIS is the wind and thermal shield, which will be placed over SEIS; to the left is a black cylindrical instrument, the Heat Flow and Physical Properties Probe (HP3); HP3 will drill up to 16 feet (5 m) below the Martian surface, measuring heat released from the interior of the planet; above the deck is InSight’s robotic arm, with the stowed grapple directly facing the camera; to the right can be seen a small portion of one of the two solar panels that help power InSight and part of the UHF communication antenna.
