NASA’s Curiosity rover quietly accomplished another photographic first today. This time it was the first nighttime photographs captured on the surface of the Red Planet.
The photographs were shot using the rover’s Mars Hand Lens Imager (MAHLI) camera, with lighting provided by white and ultraviolet LED lights.
To ensure that everything is working properly, the rover first shot a couple of photographs of the calibration target found on its body. The photograph above is of the target illuminated by the white LEDs. Here’s the same target illuminated by the UV ones:
Brightening the photograph confirms that it’s of the same target:
After photographing the calibration targets, the rover turned its camera on the martian landscape. Sadly, it wasn’t of the landscape as a whole — we likely won’t be seeing any long-exposure star trail photos — but rather a small patch of rocks and dirt:
The photo shows an area of about 1.3-inches by 1 inch. The UV exposure required an exposure time of 30 seconds, and was shot to see whether the area had any fluorescent minerals.
