Curiosity Rover Can Work Through The Night On Mars.

The Wired (1/25, Mann, 798K) “Wired Science” blog reports how the Curiosity rover, unlike Spirit and Opportunity, is able to work during the night because of its nuclear battery and the Mars Hand Lens Imager’s four white and two ultraviolet LEDs that “help it explore once the sun goes down.” The article notes, “very little is currently known about the fluorescent properties of Martian soil and the UV LEDs are mostly being used for exploratory purposes for the time being.”
