NASA’s Boeing Crew Flight Test mission teams are preparing to support a launch at 10:52 a.m. EDT Wednesday, June 5, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida on a mission of about a week to the International Space Station.

Technicians and engineers with ULA (United Launch Alliance) worked overnight and on Sunday to assess the ground support equipment at the launch pad that encountered issues during the countdown and scrubbed the June 1 launch attempt. The ULA team identified an issue with a single ground power supply within one of the three redundant chassis that provides power to a subset of computer cards controlling various system functions, including the card responsible for the stable replenishment topping valves for the Centaur upper stage. All three of these chassis are required to enter the terminal phase of the launch countdown to ensure crew safety.

On Sunday, the chassis containing the faulty ground power unit was removed, visually inspected, and replaced with a spare chassis. No signs of physical damage were observed. A full failure analysis of the power unit will be performed to better understand root cause. Meanwhile, ULA has completed functional checkouts of the new chassis and the cards, and all hardware is performing normally.

The mission managers have opted for the next launch attempt on June 5. The U.S. Space Force’s 45th Weather Squadron predicts a 90% chance of favorable weather conditions, with the cumulus cloud rule being the primary weather concern. Another opportunity is available at 10:29 a.m., Thursday, June 6.

NASA astronauts Barry “Butch” Wilmore and Suni Williams, the crew of the flight test who will be the first to launch aboard Boeing’s Starliner spacecraft, remain in quarantine at NASA’s Kennedy Space Center and will take part in pilot proficiency and other training activities leading up to launch.

Mission managers from NASA, Boeing, and ULA (United Launch Alliance) continue to evaluate a path forward toward launching the agency’s Boeing Crew Flight Test to the International Space Station. The teams are now working toward a launch opportunity at 12:25 p.m. ET on Saturday, June 1, with additional opportunities on Sunday, June 2, Wednesday, June 5, and Thursday, June 6.

Work continues to assess Starliner performance and redundancy following the discovery of a small helium leak in the spacecraft’s service module. As part of this work, and unrelated to the current leak which remains stable, teams are in the process of completing a follow-on propulsion system assessment to understand potential helium system impacts on some Starliner return scenarios. NASA also will conduct a Delta-Agency Flight Test Readiness Review to discuss the work that was performed since the last CFT launch attempt on May 6, and to evaluate issue closure and flight rationale ahead of the next attempt, as part of NASA’s process for assessing readiness. The date of the upcoming Flight Test Readiness Review is under consideration and will be announced once selected.

“There has been a great deal of exceptional analysis and testing over the last two weeks by the joint NASA, Boeing, and ULA teams to replace the Centaur Self Regulating Valve and troubleshoot the Starliner Service Module helium manifold leak,” said Steve Stich, manager, NASA Commercial Crew Program. “It has been important that we take our time to understand all the complexities of each issue including the redundant capabilities of the Starliner propulsion system and any implications to our Interim Human Rating Certification. We will launch Butch and Suni on this test mission after the entire community has reviewed the teams’ progress and flight rationale at the upcoming Delta Agency Flight Test Readiness Review.”

NASA, Boeing, and ULA officials will provide insight into the next targeted launch opportunity and updates regarding ongoing work during a media teleconference at 11 a.m. EDT Friday, May 24. NASA expects to issue a media advisory Thursday, May 23, with additional details for the call and how to participate.

Meanwhile, NASA astronauts Butch Wilmore and Suni Williams continue practicing in Starliner simulators to prepare for flight. The crew remains quarantined and will fly back to NASA’s Kennedy Space Center in Florida closer to the new launch date.

 

 

NASA, Boeing Now Working Toward May 25 Launch of Crew Flight Test

NASA, Boeing, and ULA (United Launch Alliance) teams will take additional time to work through spacecraft closeout processes and flight rationale before proceeding with the launch of the agency’s Boeing Crew Flight Test. The teams now are targeting a launch no earlier than 3:09 p.m. EDT Saturday, May 25, for the flight test carrying NASA astronauts Butch Wilmore and Suni Williams to the International Space Station.

The additional time allows teams to further assess a small helium leak in the Boeing Starliner spacecraft’s service module traced to a flange on a single reaction control system thruster. Pressure testing performed on May 15 on the spacecraft’s helium system showed the leak in the flange is stable and would not pose a risk at that level during the flight. The testing also indicated the rest of the thruster system is sealed effectively across the entire service module. Boeing teams are working to develop operational procedures to ensure the system retains sufficient performance capability and appropriate redundancy during the flight. As that work proceeds, NASA’s Commercial Crew Program and the International Space Station Program will take the next few days to review the data and procedures to make a final determination before proceeding to flight countdown.

The ULA Atlas V rocket and Boeing’s Starliner remain in the Vertical Integration Facility at Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida. The NASA, Boeing, and ULA teams remain committed to ensuring a safe Starliner flight test.

Wilmore and Williams will remain quarantined in Houston as prelaunch operations progress. They will fly back to NASA’s Kennedy Space Center in Florida closer to the new launch date. The duo is the first to launch aboard 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, 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.

Launch weather officers with Cape Canaveral Space Force Station’s 45th Weather Squadron predict a 40% chance of favorable weather conditions for the launch of NASA’s SpaceX Crew-8 mission at 11:16 p.m. EST Saturday, March 2, from the agency’s Kennedy Space Center in Florida.

A weather front across Central Florida over the next several days will bring significant cloud cover, isolated rain showers, and occasionally gusty winds. The primary weather concerns at launch will be isolated showers and thick clouds associated with the stalled front.

The Dragon spacecraft carrying NASA astronauts Matthew Dominick, commander; Michael Barratt, pilot; and Jeanette Epps, mission specialist; as well as Roscosmos cosmonaut mission specialist Alexander Grebenkin, will launch to the International Space Station on the SpaceX Falcon 9 rocket from Kennedy’s Launch Complex 39A as part of NASA’s Commercial Crew Program. The crew remains in quarantine after NASA and SpaceX selected the updated launch opportunity due to unfavorable weather conditions forecast along the Dragon’s ascent corridor during earlier opportunities. In the unlikely case of an abort during launch or the flight of Dragon, the wind and wave conditions must be within acceptable conditions for the safe recovery of the crew and spacecraft.
