NASA and Boeing now are targeting no earlier than Friday, April 2, for launch of the agency’s Boeing Orbital Flight Test-2 to the International Space Station.

As preparations continue for the second uncrewed flight test, teams remain focused on the safety and quality of the CST-100 Starliner spacecraft and successful launch of the end-to-end test to prove the system is ready to begin flying astronauts to and from the space station as part of NASA’s Commercial Crew Program.

Teams are adjusting the launch date to allow more time for spacecraft and hardware processing. Ahead of final propellant loading, the company recently replaced avionics units affected as a result of a power surge due to a ground support equipment configuration issue during final checkouts.

“NASA continues to work alongside Boeing to prepare for this first mission of 2021,” said Steve Stich, manager of NASA’s Commercial Crew Program. “The Boeing and NASA teamwork on all aspects of flight preparation including final certification, hazard analysis, and software testing is extraordinary. Even though this uncrewed flight test to the International Space Station is a key milestone on the path to the first Starliner crewed mission planned for later this year, we will fly when we are ready.”

With formal software tests completed, Boeing is continuing with flight preparations. The company is ready to conduct an end-to-end mission rehearsal, using high-fidelity flight hardware and final flight software, to ensure the readiness of the team and combined systems.

Boeing continues to support NASA as it reviews flight readiness, and teams have completed about 95% of the recommendations identified by the joint NASA and Boeing Independent Review Team, formed following the anomalies during the company’s first uncrewed Orbital Flight Test in December 2019.

“We appreciate the significant work NASA is undertaking ahead of launch,” said John Vollmer, Starliner’s vice president and program manager at Boeing. “We’re fully engaged in the agency’s review process as a valuable investment of our time to ensure confidence in the spacecraft.”
