Artemis moonsuits take a dive | Space photo of the day for July 31, 2026

NASA’s Neutral Buoyancy Laboratory in Houston, Texas, is currently central to developing astronaut training protocols for future missions on the Moon. The laboratory provides an underwater environment that closely mimics the conditions astronauts will experience during extravehicular activities – or EVAs – on the lunar surface. These simulations are crucial for preparing crews for tasks such as walking and working outside of spacesuits. NASA engineers and technicians are meticulously testing various aspects of the suits' operation within this controlled setting. This extensive preparation phase aims to ensure a safe and successful exploration program when Artemis astronauts begin their work on the moon.
