“Can’t wait to share my science results from Namib Dune; but first, let me take a selfie,” Curiosity, which arrived on Mars in 2012, said on its Facebook page over the weekend.

The rover’s latest self-portrait shows it at Namib Dune where it’s been busy gathering sand samples for lab analysis. The effort is part of an ongoing experiment to discover how Martian winds shift sand around the planet, something Curiosity is apparently learning plenty about judging by its light covering of the stuff.
The study is helping to give researchers a clearer idea of Mars’ environment, with the gathered data potentially proving critical for any future manned missions to the planet.
Looking at the selfie, you’ll notice that Curiosity’s robotic arm, at the end of which sits its Mars Hand Lens Imager (MAHLI) camera, is absent from the photo. So how did it manage that? Well, the picture comprises 57 separate images, most of which were taken with the multi-jointed arm (think of it as a high-tech selfie stick) positioned behind the camera.
NASA explains on its website, “Wrist motions and turret rotations on the arm allowed MAHLI to acquire the mosaic’s component images. The arm was positioned out of the shot in the images, or portions of images, that were used in this mosaic.”
This Instagram video also provides a brief explanation:
The same process was used to acquire and assemble other Curiosity selfies taken at various sample-collection sites on the planet, including Rocknest, Windjana, and Buckskin.
