Astronauts Practice Station Spacewalk Underwater

Astronauts Robert Satcher Jr. and Rick Sturckow conduct an underwater practice spacewalk session at Johnson Space Center’s Neutral Buoyancy Laboratory. The session was used to help International Space Station team members identify challenges that will need to be addressed when Expedition 24 astronauts perform the first of two planned spacewalks to replace a failed ammonia pump module.
