An engineer monitors a Boeing CST-100 Starliner spacecraft inside Boeing's Commercial Crew and Cargo Processing Facility at NASA's Kennedy Space Center in Florida. This was the first time "Spacecraft 1," as the individual Starliner is known, was powered up. It is being assembled for use during a pad abort test that will demonstrate the Starliners' ability to lift astronauts out of danger in the unlikely event of an emergency. Later flight tests will demonstrate Starliners in orbital missions to the station without a crew, and then with astronauts aboard. The flight tests will preview the crew rotation missions future Starliners will perform as they take up to four astronauts at a time to the orbiting laboratory in order to enhance the research taking place there

The Boeing CST-100 Starliner spacecraft is back home at the company's Commercial Crew and Cargo Processing Facility, undergoing inspection after its first flight as part of NASA's Commercial Crew Program, known as the Orbital Flight Test. Starliner launched atop a United Launch Alliance Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station (CCAFS) in Florida, Friday, Dec. 20, 2019. The mission successfully landed two days later on Sunday, Dec. 22, completing an abbreviated test that performed several mission objectives before returning to Earth as the first orbital land touchdown of a human-rated capsule in U.S. history.

A suit technician prepares for a pressure test of Boeing's new spacesuit designed to be worn by astronauts flying on the CST-100 Starliner. Seen here being worn in the same manner as it will on launch day inside Crew Quarters at NASA's Kennedy Space Center in Florida, 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.

Engineers working with Boeing's CST-100 Starliner test the spacecraft's seat design in Mesa, Arizona, focusing on how the spacecraft seats would protect an astronaut's head, neck and spine during the 240-mile descent from the International Space Station. The company incorporated test dummies for a detailed analysis of impacts on a crew returning to earth. The human-sized dummies were equipped with sensitive instrumentation and secured in the seats for 30 drop tests at varying heights, angles, velocities and seat orientations in order to mimic actual landing conditions. High-speed cameras captured the footage for further analysis. The Starliner spacecraft is being developed in partnership with NASA's Commercial Crew Program.

At NASA’s Langley Research Center in Hampton, Virginia, a mock-up of the Boeing CST-100 Starliner spacecraft goes through a series of land landing qualification tests to simulate what the actual spacecraft and crew members may experience while returning to Earth from space. The Starliner is being developed in collaboration with NASA’s Commercial Crew Program. Along with SpaceX’s Crew Dragon, the spacecraft is part of the agency’s effort to return America’s capability to launch astronauts from the agency's Kennedy Space Center in Florida to the International Space Station.

Boeing, NASA and U.S. Army teams rehearse safely bringing the CST-100 Starliner spacecraft home to Earth on Wed., June 6, 2018, at the U.S. Army's White Sands Missile Range in New Mexico. During the detailed landing simulation, engineers, technicians and spaceflight specialists worked through tight timelines and intense heat running through simulations of the spacecraft's landing and recovery, an operation that will cap each Starliner mission. For flight controllers at Mission Control in Houston, the simulation offered the chance to evaluate their own processes and rehearse everything from undocking the Starliner from the space station to communicating with the recovery teams in the field.

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.

Boeing’s CST-100 Starliner lands in the New Mexico desert in the company’s Pad Abort Test for NASA’s Commercial Crew Program. The test, conducted Nov. 4 at the White Sands Missile Range, was designed to verify that each of Starliner’s systems will function not only separately, but in concert, to protect astronauts by carrying them safely away from the launch pad in the unlikely event of an emergency prior to liftoff. Starliner touched down on land approximately 90 seconds after the test began, about one mile from the test stand at Launch Complex 32. This is Boeing’s first test flight for NASA’s Commercial Crew Program, which is working to launch astronauts on American rockets and spacecraft from American soil for the first time since 2011.

On Nov. 12, 2018, inside the Commercial Crew and Cargo Processing Facility (C3PF) at NASA's Kennedy Space Center in Florida, technicians and engineers prepare the company's CST-100 Starliner for transport to the company's testing facilities in El Segundo, California. The spacecraft is destined to fly astronauts to the International Space Station in Boeing's Crew Flight Test (CFT) as part of NASA's Commercial Crew Program (CCP). The Starliner will be undergoing a series of environmental tests designed to simulate what the spacecraft will experience during different stages of flight. The agency's CCP will return human spaceflight launches to U.S. soil, providing safe, reliable and cost-effective access to low-Earth orbit on systems that meet our safety and mission requirements.

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

On August 2, 2021, Boeing’s CST-100 Starliner spacecraft and the United Launch Alliance Atlas V rocket rolls out from the Vertical Integration Facility to the launch pad at Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida. Starliner will launch on the Atlas V for Boeing’s second uncrewed Orbital Flight Test (OFT-2) for NASA’s Commercial Crew Program. OFT-2 is an important uncrewed mission designed to test the end-to-end capabilities of the new system for NASA’s Commercial Crew Program.
