Lights out!

Divers at the Neutral Buoyancy Laboratory at NASA's Johnson Space Center simulated the low-light environment an astronaut might experience on NASA Artemis missions to the Moon's south pole, where the Sun will only peak a few degrees above the horizon.

Teams at the pool turned off the lights and used a powerful underwater lamp to create dark, long shadows and evaluated the different lighting configurations.

While this test used wet suits and SCUBA gear, later this year NASA plans to conduct the low-light test again using spacesuits.
