Editor’s note: This blog was updated Oct. 8 to reflect that the team is working toward launch opportunities in the first half of 2022 for Orbital Flight Test-2.

The NASA, Boeing team continues to make progress on the investigation of the oxidizer isolation valve issue on the Starliner service module propulsion system that was discovered ahead of the planned uncrewed Orbital Flight Test-2 (OFT-2) mission to the International Space Station in August.

“I am proud of the work our integrated teams are doing,” said Steve Stich, manager of the Commercial Crew Program at NASA’s Kennedy Space Center in Florida. “This is a complex issue involving hazardous commodities and intricate areas of the spacecraft that are not easily accessed. It has taken a methodical approach and sound engineering to effectively examine.”

Boeing has demonstrated success in valve functionality using localized heating and electrical charging techniques. Troubleshooting on the pad, at the launch complex, and inside the Starliner production factory at Kennedy Space Center has resulted in movement of all but one of the original stuck valves. That valve has not been moved intentionally to preserve forensics for direct root cause analysis.

Most items on the fault tree have been dispositioned by the team including causes related to avionics, flight software and wiring. Boeing has identified a most probable cause related to oxidizer and moisture interactions, and although some verification work remains underway, our confidence is high enough that we are commencing corrective and preventive actions. Additional spacecraft and component testing will be conducted in the coming weeks to further explore contributing factors and necessary system remediation before flight.

Boeing completed a partial disassembly of three of the affected Orbital Maneuvering and Attitude Control (OMAC) thruster valves last month and plans to remove three valves from the OFT-2 spacecraft in the coming weeks for further inspection. The team also is evaluating additional testing to repeat the initial valve failures.

Boeing has identified several paths forward depending on the outcome of the testing to ultimately resolve the issue and prevent it from happening on future flights. These options could range from minor refurbishment of the current service module components to using another service module already in production. Each option is dependent on data points the team expects to collect in the coming weeks including a timeline for safely proceeding back to the launch pad.

“Safety of the Starliner spacecraft, our employees, and our crew members is this team’s number one priority,” said John Vollmer, vice president and program manager, Boeing’s Starliner program. “We are taking the appropriate amount of time to work through the process now to set this system up for success on OFT-2 and all future Starliner missions.”

Potential launch windows for OFT-2 continue to be assessed by NASA, Boeing, United Launch Alliance, and the Eastern Range. The team currently is working toward opportunities in the first half of 2022 pending hardware readiness, the rocket manifest, and space station availability.

NASA continues to work side-by-side with Boeing to understanding the CST-100 Starliner’s service module valve performance, including the unexpected indications some of the valves were in the closed position during its Aug. 3 launch attempt of Orbital Flight Test-2 (OFT-2).

With troubleshooting ongoing in the United Launch Alliance Vertical Integration Facility at NASA’s Kennedy Space Center in Florida, where Starliner will be powered and run through various procedures to help understand the issue, NASA will move forward with the launch and berthing of an important cargo mission to the International Space Station.

Northrop Grumman’s Cygnus spacecraft is scheduled to launch on the company’s Antares rocket at 5:56 p.m. Tuesday, Aug. 10, from NASA’s Wallops Flight Facility in Wallops Island, Virginia, with capture and berthing scheduled two days later at about 6:10 a.m. EDT Thursday, Aug. 12.

In parallel, managers and engineers with NASA and Boeing will continue to evaluate schedules based on where the troubleshooting efforts take them before deciding when the next official launch for the OFT-2 mission will take place.

When Boeing’s Orbital Flight Test (OFT) launches on Dec. 20, 2019, it will be a major step toward returning human spaceflight capability to the U.S.

The uncrewed mission for NASA’s Commercial Crew Program will rendezvous and dock Boeing’s CST-100 Starliner spacecraft with the International Space Station and return to Earth on Dec. 28. Starliner will launch atop a United Launch Alliance Atlas V rocket from Space Launch Complex 41 (SLC-41) at Cape Canaveral Air Force Station in Florida.

“This test flight will give us valuable data about Starliner’s performance in the actual environment through each phase of flight and demonstrate its capability to transport crew to the space station and bring them home safely,” said Trip Healey, NASA’s mission manager for OFT. “Being on the cusp of this huge moment in history is really exciting.”

Data from the mission will validate spacecraft system performance and will move Starliner farther down the path toward its first flight with astronauts aboard — Boeing’s Crew Flight Test (CFT).

NASA astronauts Michael Fincke and Nicole Mann and Boeing astronaut Chris Ferguson will be onboard Starliner for CFT. All three were on hand when the spacecraft for this flight test rolled out of Boeing’s Commercial Crew and Cargo Processing Facility at NASA’s Kennedy Space Center in Florida on Nov. 21, making the roughly six mile trek on a transport vehicle to SLC-41 to be mated atop the Atlas V rocket.
