Boeing’s CST-100 Starliner’s four launch abort engines and several orbital maneuvering and attitude control thrusters ignite in the company’s Pad Abort Test, pushing the spacecraft away from the test stand with a combined 160,000 pounds of thrust, from Launch Complex 32 on White Sands Missile Rangein New Mexico. The test, conducted Nov. 4, 2019, 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. The Pad Abort Test 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.
