The Crew Access Arm and White Room for Boeing's CST-100 Starliner are attached to the Crew Access Tower at Cape Canaveral Air Force Station’s Space Launch Complex 41. The arm will serve as the connection that astronauts will walk through prior to boarding the Starliner spacecraft when stacked atop a United Launch Alliance Atlas V rocket. This installation completes the major construction of the first new Crew Access Tower to be built at the Cape since the Apollo era. Under a Commercial Crew Transportation Capability contract with NASA, Boeing’s Starliner system will be certified by NASA's Commercial Crew Program to fly crews to and from the International Space Station.

A crane lifts the Crew Access Arm and White Room for Boeing's CST-100 Starliner spacecraft to be attached to the Crew Access Tower at Cape Canaveral Air Force Station’s Space Launch Complex 41. When attached to the 200-foot tall Crew Access Tower, the arm will serve as the connection that astronauts will walk through prior to boarding the Starliner spacecraft when stacked atop a United Launch Alliance Atlas V rocket. This installation completes the major construction of the first new Crew Access Tower to be built at the Cape since the Apollo era. Under a Commercial Crew Transportation Capability (CCtCap) contract with NASA, Boeing’s Starliner system will be certified by NASA's Commercial Crew Program to fly crews to and from the International Space Station.

SpaceX performed its fourteenth overall parachute test supporting Crew Dragon development. This most recent exercise was the first of several planned parachute system qualification tests ahead of the spacecraft’s first crewed flight and resulted in the successful touchdown of Crew Dragon’s parachute system. During this test, a C-130 aircraft transported the parachute test vehicle, designed to achieve the maximum speeds that Crew Dragon could experience on re-entry, over the Mojave Desert in Southern California and dropped the vehicle from an altitude of 25,000 feet. The test demonstrated an off-nominal situation, deploying only one of the two drogue chutes and intentionally skipping a reefing stage on one of the four main parachutes, proving a safe landing in such a contingency scenario.

In this illustration, a Boeing CST-100 Starliner spacecraft is shown in low-Earth orbit. NASA is partnering with Boeing and SpaceX to build a new generation of human-rated spacecraft capable of taking astronauts to the International Space Station and expanding research opportunities in orbit. Boeing's upcoming Orbital Flight Test is part of NASA’s Commercial Crew Transportation Capability contract with the goal of returning human spaceflight launch capabilities to the United States.

The upper and lower domes of the Boeing CST-100 Starliner Spacecraft 2 Crew Flight Test Vehicle were mated June 19, 2018, inside the Commercial Crew and Cargo Processing Facility (C3PF) at Kennedy Space Center in Florida. The Starliner will launch astronauts on a United Launch Alliance Atlas V rocket to the International Space Station as part of NASA’s Commercial Crew Program.

Astronauts assigned to crew the first flight tests and missions of the Boeing CST- 100 Starliner and SpaceX Crew Dragon were announced during the event.

Commercial Crew Program astronauts try out some of the food they’ll enjoy onboard the International Space Station at the Space Food Systems Laboratory at Johnson Space Center in Houston. NASA astronauts Bob Behnken, Doug Hurley, Mike Hopkins and Victor Glover will fly on the SpaceX Crew Dragon. NASA astronaut Kjell Lindgren is assigned as a backup for the Crew Dragon’s first and second crewed flights. Boeing astronaut Chris Ferguson will fly on Boeing’s CST-100 Starliner. Also joining them for the taste tests are Japan Aerospace Exploration Agency astronauts Shoichi Noguchi and Akihiko Hoshide. Noguchi is scheduled to be part of the Expedition 62-63 crew, and Hoshide is training for Expedition 64-65.

NASA astronauts Eric Boe, from left, Barry "Butch" Wilmore and Suni Williams listen as United Launch Alliance engineer Tom Harper discusses aspects of an RL10 engine during a tour of Aerojet Rocketdyne's facility in West Palm Beach, Florida. The engine will be one of two used for the Centaur upper stage during a United Launch Alliance Atlas V mission to launch Boeing's CST-100 Starliner on a flight test carrying a crew. The engine was test-fired as part of acceptance testing to confirm the engine is ready for flight.
