NASA and Boeing continue to make progress toward the company’s second uncrewed flight test of the CST-100 Starliner spacecraft prior to flying astronauts to the International Space Station as part of NASA’s Commercial Crew Program.
The Commercial Crew Program currently is targeting no earlier than December 2020 for launch of the uncrewed Orbital Flight Test-2 (OFT-2) pending hardware readiness, flight software qualification, and launch vehicle and space station manifest priorities.
Over the summer, Boeing’s Starliner team focused on readying the next spacecraft for its upcoming flight tests as well as making improvements identified during various review processes throughout the beginning of the year. NASA also announced an additional crew assignment for its first operational mission, NASA’s Boeing Starliner-1, with astronauts to the space station.
Boeing and Aerojet Rocketdyne have begun a series of developmental hot-fires tests with two launch abort engines similar to the ones that will be part of Boeing’s Starliner service module. The engines, designed to maximize thrust build-up, while minimizing overshoot during start up, will be fired between half a second and 3 seconds each during the test campaign. If the Starliner’s four launch abort engines were used during an abort scenario, they would fire between 3 and 5.5 seconds, with enough thrust to get the spacecraft and its crew away from the rocket, before splashing down in the ocean under parachutes.
Recently, Aerojet Rocketdyne also completed delivery of the first set of hardware for Starliner’s service module propulsion system.
The Starliner is under development in collaboration with NASA’s Commercial Crew Program for crew missions to the International Space Station.
