NASA astronaut Eric Boe wears Boeing's new spacesuit designed to be worn by astronauts flying on the CST-100 Starliner. The suit is lighter and more flexible than previous spacesuits but retains the ability to pressurize in an emergency. Astronauts will wear the suit throughout the launch and ascent into orbit as well as on the way back to Earth. Starliners will launch atop Atlas V rockets from United Launch Alliance on missions including flights to the International Space Station for NASA's Commercial Crew Program. NASA's commercial crew astronauts Boe and Suni Williams tried on the suits at Boeing’s Commercial Crew and Cargo Facility at NASA’s Kennedy Space Center. Boe, Williams, Bob Behnken, and Doug Hurley were selected by NASA in July 2015 to train for commercial crew test flights aboard the Starliner and SpaceX’s Crew Dragon spacecraft. The flight assignments have not been set, so all four of the astronauts are rehearsing heavily for flights aboard both vehicles. Photo credit: Boeing
