— Science stories you may have missed

When you’re on a big trip, you gotta let friends know.

NASA’S Opportunity rover may be dead, but its sibling Curiosity is still keen on a quick selfie. It took this happy snap in late January at the “Rock Hall” drill site, located on Mars’s Vera Rubin Ridge.

In fact, there are 57 individual images here – all taken by the Mars Hand Lens Imager (MAHLI) – then stitched together into a panorama.

The scene is dustier than usual, NASA says, due to a dust storm.
