NASA is to test colour-changing lights on the International Space Station (ISS) as part of efforts to help astronauts on board sleep.

 

The US space agency will initially swap a fluorescent panel with a solid-state lighting module (SSLM) containing LEDs which produces a blue, whitish or red-coloured light depending on the time.
