NASA scientists working on the Curiosity rover have had a lot to worry about over the years, with discoveries coming regularly, revealing painstaking details about the Red Planet and its history. The robot recently conducted a "special chemistry experiment" for only the second time in its history, and the completion of this experiment was marked by a brand new north with a rover.
The photo that NASA posted on its website was clicked on October 11, and although we view it as a single image, it is actually the result of 57 separate photos that were stitched after the fact.
NASA's curiosity rover has been hanging on Mars for over seven years, working hard to shed light on as many secrets as possible on the planet. He has spent his entire life on Mars exploring a massive impact area known as the Galle Crater.
One of the most interesting features in the crater is the towering mountain region known as Sharpe Mountain. The rover has been climbing for some time on Mount Sharp, reaching an area known as the clay unit. As the name implies, it is an area of open clay-based rocks, and because the clay is so good at revealing chemical history, the rover is able to experiment with "wet chemistry" using special glasses designed specifically for this purpose.  "We couldn't wait to find an area that was fascinating enough to deal with wet chemistry," says Paul Mahaha of the NASA Goddard Space Flight Center. "Now that we are in the clay unit, we have finally got it."
The experiments take a long time to complete and the researchers back to Earth will not know the results until sometime in 2020. However, this was an occasion appropriate for selfies.
