A dart-shaped device, functioning as a Boeing CST-100 Starliner weight simulant, drops from a C-17 aircraft during parachute system testing at the U.S. Army’s Yuma Proving Ground in Arizona on June 26, 2019. This “high Q” test involved intentionally inflating the parachutes at higher pressures than expected during missions, to 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.
