Anyone who’s watched a sci-fi film of late about deep space knows the importance of a good night’s sleep. In outer space, Hollywood has informed us, people run the risk of going a little cuckoo, and one of the best ways to stave off an Event Horizon scenario (or, more mundanely, to simply keep astronauts performing at their best) may be to ensure they all get some serious shut-eye.
And how do we help astronauts get some rest, so far from home? With technology, of course. NASA will reportedly test special color-changing lights aboard the International Space Station, reports the BBC. The test, which should run in 2016, involves replacing fluorescent lights for something called a solid-state lighting module (SSLM, for short). The SSLM lights contain LEDs which variously produce blue, white, or red light, depending on time–something which NASA hopes will reduce insomnia, and, in turn, mental health problems like depression.
The experiment will run specifically in the US section of the ISS, reports Space.com, which adds that the product should somehow manage to cost $11.2 million. The site adds that though astronauts are generally permitted to have 8.5 hours of shut-eye, they typically only take six. “The station is noisy, carbon dioxide is high, you don’t have a shower, there’s a lot of angst because you’ve got to perform. Imagine if you have a camera on you 24 hours a day,” the lead physician for NASA’s wellness program told Space.com.
