Astronauts practise tasks in simulated moon environment and underwater. Astronauts have been practising walking on the Moon as their next-generation spacesuit passes milestone testing. NASA astronauts and spacesuit engineers recently simulated lunar surface operations and tasks underwater wearing the new suits, built by Axiom Space, to demonstrate safety and mobility. The space agency reported Thursday (Feb 12) that the spacesuit has passed a contractor-led technical review and is hoped to be used for the Artemis III mission as NASA prepares to send humans to the Moon???s South Pole for the first time. NASA said: "The AxEMU (Axiom Extravehicular Mobility Unit) is designed to give astronauts increased flexibility and improved mobility for moonwalking, including bending down to collect geology samples and perform a variety of scientific tasks."
