Managers from NASA, Boeing, and ULA (United Launch Alliance) hosted a media teleconference to discuss ongoing work ahead of sending NASA astronauts Butch Wilmore and Suni Williams to the International Space Station as part of the agency’s Boeing Crew Flight Test. 

The media event provided an update on a valve ULA replaced on the Centaur upper stage of the Atlas V rocket, as well as a small helium leak in the spacecraft’s service module, and a propulsion system assessment to understand potential helium system impacts on some Starliner return scenarios. 

Listen to a replay of the media teleconference on the agency’s YouTube channel. 

Wilmore and Williams are the first to launch aboard Boeing’s Starliner on an Atlas V rocket. The astronauts will spend about a week at the orbiting laboratory before the crew capsule makes a parachute and airbag-assisted landing in the southwestern United States. 

The crew remains in quarantine in preparation for the launch. NASA, Boeing, and ULA also will participate in a Delta-Agency Flight Test Readiness Review on Wednesday, May 29, to evaluate the work performed since the last launch attempt on May 6. 

Liftoff is scheduled for 12:25 p.m. Saturday, June 1, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. After successful completion of the flight test, NASA will begin the final process of certifying Starliner and its systems for crewed rotation missions to the space station.

NASA, Boeing, and ULA (United Launch Alliance) teams continue working remaining open tasks in preparation for the agency’s Boeing Crew Flight Test to the International Space Station. The teams now are targeting a launch date of no earlier than 4:43 p.m. EDT on Tuesday, May 21, to complete additional testing.

On May 11, the ULA team successfully replaced a pressure regulation valve on the liquid oxygen tank on the Atlas V rocket’s Centaur upper stage. The team also performed re-pressurization and system purges, and tested the new valve, which performed normally.

Starliner teams are working to resolve a small helium leak detected in the spacecraft’s service module traced to a flange on a single reaction control system thruster. Helium is used in spacecraft thruster systems to allow the thrusters to fire and is not combustible or toxic.

NASA and Boeing are developing spacecraft testing and operational solutions to address the issue. As a part of the testing, Boeing will bring the propulsion system up to flight pressurization just as it does prior to launch, and then allow the helium system to vent naturally to validate existing data and strengthen flight rationale. Mission teams also completed a thorough review of the data from the May 6 launch attempt and are not tracking any other issues.

The Atlas V and Starliner remain in the Vertical Integration Facility at Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida.

NASA astronauts Butch Wilmore and Suni Williams, still in preflight quarantine, returned to Houston on May 10 to spend extra time with their families as prelaunch operations progress. The duo will fly back to NASA’s Kennedy Space Center in Florida in the coming days.

Wilmore and Williams are the first to launch aboard Boeing’s Starliner to the space station as part of the agency’s Commercial Crew Program. The astronauts will spend about a week at the orbiting laboratory before returning to Earth and making a parachute and airbag-assisted landing in the southwestern United States.

After successful completion of the mission, NASA will begin the final process of certifying Starliner and its systems for crewed rotation missions to the space station.

NASA’s Boeing Crew Flight Test now is targeted to launch no earlier than 6:16 p.m. EDT Friday, May 17, to the International Space Station. Following a thorough data review completed on Tuesday, ULA (United Launch Alliance) decided to replace a pressure regulation valve on the liquid oxygen tank on the Atlas V rocket’s Centaur upper stage.

ULA plans to roll the rocket, with Boeing’s Starliner spacecraft, back to its Vertical Integration Facility at Cape Canaveral Space Force Station in Florida on Wednesday, May 8, to begin the replacement. The ULA team will perform leak checks and functional checkouts in support of the next launch attempt.

The oscillating behavior of the valve during prelaunch operations, ultimately resulted in mission teams calling a launch scrub on May 6. After the ground crews and astronauts Butch Wilmore and Suni Williams safely exited from Space Launch Complex-41, the ULA team successfully commanded the valve closed and the oscillations were temporarily dampened. The oscillations then re-occurred twice during fuel removal operations. After evaluating the valve history, data signatures from the launch attempt, and assessing the risks relative to continued use, the ULA team determined the valve exceeded its qualification and mission managers agreed to remove and replace the valve.

Mission managers discussed the details leading to the decision to scrub the May 6 launch opportunity during a news conference shortly after the scrub call at NASA’s Kennedy Space Center in Florida.

Wilmore and Williams will remain in crew quarters at NASA Kennedy in quarantine until the next launch opportunity. The duo will be the first to launch aboard Starliner to the space station as part of the agency’s Commercial Crew Program.

NASA’s Boeing Crew Flight Test Targets No Earlier than Friday, May 10

After the first launch attempt of NASA’s Boeing Crew Flight Test, a news conference is held on Monday, May 6, 2024 at the agency’s Kennedy Space Center in Florida. As part of the agency’s Commercial Crew Program, the first crewed launch to the International Space Station aboard Boeing’s Starliner spacecraft atop a United Launch Alliance Atlas V rocket from Space Launch Complex-41 at nearby Cape Canaveral Space Force Station was targeted for 10:34 p.m. ET but scrubbed for the day.  Photo credit: NASA/Kim Shiflett

NASA, Boeing, and ULA (United Launch Alliance) are targeting no earlier than Friday, May 10, for launch of the agency’s Boeing Crew Flight Test to the International Space Station, pending resolution of the technical issue that prevented the May 6 launch attempt.

The delay allows teams to complete data analysis on a pressure regulation valve on the liquid oxygen tank of the Atlas V rocket ‘s Centaur upper stage and determine whether it is necessary to replace the valve.

Mission managers discussed the details that led to the decision during a news conference Monday night at NASA’s Kennedy Space Center.

Following the scrub, NASA astronaut Butch Wilmore and Suni Williams exited the Starliner spacecraft and launch pad at Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida and returned to the astronaut crew quarters at Kennedy. ULA, as per the normal recycle process, also removed liquid oxygen and hydrogen from the Atlas V first and second stages.
