NEEMO 20 mission objective was to simulate the time delays associated with sending and receiving commands between controllers on Earth and astronauts on Mars. Additional EVAs will simulate working on the surface of an asteroid, and the use of the DeepWorker submersible as an underwater stand-in for the Multi-Mission Space Exploration Vehicle. [50]
Scientists on the Aquarius are often called "aquanauts" (as they live underwater at depth pressure for a period equal to or greater than 24 continuous hours without returning to the surface). A technique known as saturation diving allows the aquanauts to live and work underwater for days or weeks at a time. After twenty-four hours underwater at ...
Astronaut Kathryn D. Sullivan and mountaineer Vanessa O'Brien were the first two women to visit Challenger Deep in 2020. [5] Victor Vescovo has made the most dives to Challenger Deep; by August 2022 he had made eleven dives to the Eastern pool, two to the Western pool, and two to the Central pool for a total of 15 dives.

Before they go to the International Space Station, NASA astronauts head the other direction -- to the bottom of the ocean. They dive down to Aquarius the world's only undersea
Yesterday (Sunday, January 5), Rüdiger Koch set a new world record for the longest continuous stay below the water in an underwater room.The aerospace engineer spent 101 days under the Caribbean ...
The term aquanaut derives from the Latin word aqua ("water") plus the Greek nautes ("sailor"), by analogy to the similar construction "astronaut".The word is used to describe a person who stays underwater, breathing at the ambient pressure for long enough for the concentration of the inert components of the breathing gas dissolved in the body tissues to reach equilibrium, in a state known as ...
NASA's next crew of four was supposed to launch in February, followed by Wilmore and Williams' return home by the end of that month alongside two other astronauts. But SpaceX needs more time to prepare the brand new capsule for liftoff. That launch is now scheduled for no earlier than late March.
There are concerns about possible interference with radio-quiet zones used for scientific research. The increasing number of satellites also contributes to growing space debris concerns.
