Slideshow: How NASA uses LEDs
So, covering LEDs on this site led me to look at how the folks at NASA are using LEDs. From medical, photographs from Rovers, to growing plants, and more. I’ve put together some of the uses in this slideshow. This just scratches the proverbial surface. There are many more uses in helmets, as interior lights, on equipment, etc.
A photo of taken of a Martian rock illuminated by UV-LEDs is one of the first images taken by the Mars Hand Lens Imager (MAHLI) camera located at the end of Mars rover Curiosity’s robotic arm. MAHLI’s two UV LEDs emit light in a waveband centered at a wavelength of 365 nm. Exposure duration was 30 seconds. UV illumination is important when looking for fluorescent minerals.
NASA's Mars Science Laboratory project is using Curiosity to investigate whether the Gale Crater has environmental conditions favorable for microbial life.
