Watch NASA astronauts train in simulated lunar-like underwater conditions – Technology News, Firstpost

National Aeronautics and Space Administration (NASA) often posts stunning photos of the universe on its social media account. But this time, the agency has posted some images of divers “at the bottom of a very dark pool” training for NASA’s upcoming moon mission.

Taking viewers behind the intense preparation needed to send people into space, the images have intrigued social media users.

The images come from a recent test at the Neutral Buoyancy Laboratory at NASA’s Johnson Space Center. The images show a group of divers moving in near pitch dark conditions. The images were shared three days ago, on February 6.

According to NASA, these tests are designed to prepare astronauts for future missions by exposing them to conditions similar to those found on the moon, such as lunar terrain, suit mobility and one-sixth gravity.

NASA also detailed how it creates an environment similar to the moon’s south pole, where the agency plans to send its upcoming Artemis mission. At the moon’s south pole, the sun will be only a few degrees above the horizon, creating long, dark shadows. To create a similar environment, divers “turned off the lights, hung black curtains on the walls of the pool to minimize reflection, and used powerful underwater lights to simulate the environment astronauts might experience during lunar missions.”

The sand visible in the images is regular pool filter sand, mixed with a number of other specialized materials, according to the agency. NASA also stated that the current test was with divers in scuba gear to get the lighting conditions accurate. The agency will soon be testing spacesuits in a low-light environment.

Since they were posted, the images have been liked more than 984,000 times. Several social media users have called the photos “spooky,” while others praised the agency for the stunning images.
