You might think the quiet of space would help astronauts sleep on the International Space Station. But NASA is preparing to replace the station’s florescent panel lights with solid-state lighting modules that would dim and change hues between colors to reflect the time of day.
To combat insomnia that can trigger depression or sickness, the new SSLM panels are made up of LEDs that can transition between blue, white and red. The colors correspond to different cycles of sleep that we’re used to on Earth. In 2001, NASA reported that nearly 50% of crews on space missions took sleeping pills to help them fall asleep.
NASA plans to test the new lighting in 2016 at a budget of nearly $11.2 million. Watch the video above to learn more.
