Members of the 2017 class of astronaut candidates view the new work platforms in High Bay 3 of the Vehicle Assembly Building during a familiarization tour at NASA's Kennedy Space Center in Florida. The candidates toured center facilities, including the Neil Armstrong Operations and Checkout Building high bay, Launch Control Center, Launch Pad 39B, and the Space Station Processing Facility. They also toured Boeing's Commercial Crew and Cargo Facility, United Launch Alliance's Space Launch Complex 41 at Cape Canaveral Air Force Station, and SpaceX's Launch Pad 39A at Kennedy. The candidates will spend about two years getting to know the space station systems and learning how to spacewalk, speak Russian, control the International Space Station's robotic arm and fly T-38s, before they're eligible to be assigned to a mission.
