NASA has yet to decide which astronauts will travel to the moon. The agency has said it hopes to choose which astronauts will fly aboard Artemis II later this year. The agency will primarily consider technical expertise for all of the Artemis missions, as NASA's Wiseman recently said. That includes "the ability to dive into literally any situation, any technical need of the vehicle, to understand when things aren't going quite right, and to understand when they are."Beyond that, he said, NASA is looking for team players who can work well with each other and flight directors. Wiseman also stressed the significance of sending a diverse crew to the moon, noting that the incoming class of astronauts represents "all walks of life." In the meantime, NASA's team of 42 astronauts and 10 astronaut candidates are going through rigorous training. It involves landing Army helicopters, studying rocky terrain in areas like Iceland, spending extended periods at the bottom of a pool, and training in VR simulations.
