iss072e422426 (Dec. 27, 2024) --- NASA astronaut and Expedition 72 Commander Suni Williams wears a virtual reality headset and practices emergency maneuvers a spacewalker would use in the unlikely event they became untethered from the International Space Station. During spacewalks astronauts wear U.S. spacesuits with a jetpack installed called a SAFER, or Simplified Aid for EVA (Extra Vehicular Activity) Rescue, that contains a controller and thrusters used to guide a crew member back to the safety of the orbital outpost.
