A C-17 aircraft flies above the U.S. Army’s Yuma Proving Ground in Arizona during testing of the Boeing CST-100 Starliner’s parachute system on June 26, 2019. This test, known as a “high Q” test, involved releasing a dart-shaped device – functioning as a Starliner weight simulant – from the aircraft and intentionally inflating the parachutes at higher pressures than expected during missions. The data gathered from this parachute test will help validate the system is safe to carry astronauts to and from the International Space Station as part of NASA’s Commercial Crew Program. Boeing is targeting an uncrewed Orbital Flight Test to the space station this summer, followed by its Crew Flight Test. Starliner will launch atop a United Launch Alliance Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.
