Lately, especially considering the activity at this site, I’ve thought that wondering around at night and looking for fluorescent rocks makes one an anachronism.
But maybe not if you’re looking for them on Mars. It’s the latest thing up there. 😉
The illumination came from MAHLI’s two ultraviolet LEDs, which emit light in a waveband centered at a wavelength of 365 nanometers. The exposure duration was 30 seconds. The purpose of acquiring observations under ultraviolet illumination was to look for fluorescent minerals. This image and caption are being posted before analysis is completed about whether fluorescent minerals are present.
