After snagging a new rock sample on Aug. 9, NASA’s Curiosity rover surveyed its surroundings on Mars, producing a 360-degree panorama of its current location on Vera Rubin Ridge.

The panorama includes umber skies, darkened by a fading global dust storm. It also includes a rare view by the Mast Camera of the rover itself, revealing a thin layer of dust on Curiosity’s deck. In the foreground is the rover’s most recent drill target, named “Stoer” after a town in Scotland near where important discoveries about early life on Earth were made in lakebed sediments.

The new drill sample delighted Curiosity’s science team, because the rover’s last two drill attempts were thwarted by unexpectedly hard rocks. Curiosity started using a new drill method earlier this year to work around a mechanical problem. Testing has shown it to be as effective at drilling rocks as the old method, suggesting the hard rocks would have posed a problem no matter which method was used.

There’s no way for Curiosity to determine exactly how hard a rock will be before drilling it, so for this most recent drilling activity, the rover team made an educated guess. An extensive ledge on the ridge was thought to include harder rock, able to stand despite wind erosion; a spot below the ledge was thought more likely to have softer, erodible rocks. That strategy seems to have panned out, but questions still abound as to why Vera Rubin Ridge exists in the first place.
