Artemis II astronauts struggle to walk as gravity hits them

NASA's Artemis II crew successfully splashed down after their historic moon mission, as their Orion spacecraft made a fiery plunge through Earth's atmosphere.The four-person crew, NASA astronauts Reid Wiseman, Victor Glover and Christina Koch, along with Canadian astronaut Jeremy Hansen, wrapped up a ten-day mission that carried them around the moon and farther than any human had ever traveled into space before.Following their recovery from the Orion crew module and transfer to the naval vessel John P Murtha, the astronauts were seen in good spirits, waving to cameras and hugging Isaacman before heading for a standard medical checkup after the flight. All four astronauts were also able to walk under their own power. Previous space flights, including the ten-month saga of stranded astronauts Butch Wilmore and Suni Williams, required medical personnel to carry the astronauts because they were unable to walk well from their time in microgravity.
