The mission will carry NASA astronauts Raja Chari, Tom Marshburn, and Kayla Barron, as well as ESA (European Space Agency) astronaut Matthias Maurer, to the International Space Station for a six-month stay. Launch is scheduled for 2:21 a.m. EDT, and the crew is expected to arrive at the orbiting laboratory about 22 hours later, at 12:10 a.m. EDT on Monday, Nov.1.

Upon their arrival, the Crew-3 astronauts will have a short overlap with NASA astronauts Shane Kimbrough and Megan McArthur, JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide, and ESA astronaut Thomas Pesquet, who flew to the station as part of the agency’s SpaceX Crew-2 mission in April 2021. Crew-2 astronauts are scheduled to return to Earth in early November.

The mission will fly a new Crew Dragon spacecraft, which crew members have named Endurance, and will be the first to fly a previously used nosecone. In support of Crew-3, SpaceX implemented several improvements to the Crew Dragon system based on knowledge gained from previous flights, including making a software change to build in more communications robustness against radiation effects while docked, adding more cleaning techniques to cut down on foreign object debris, improving computer performance during re-entry, and enhancing the spacecraft’s docking procedures and mechanisms to mitigate hardware interference on the space station side of the interface.

Tomorrow, Oct. 28, the Crew-3 astronauts and launch teams will conduct a full dress rehearsal in preparation for launch. Find out what that entails in the video below.

NASA astronauts Raja Chari, Tom Marshburn, and Kayla Barron, as well as ESA (European Space Agency) astronaut Matthias Maurer, will hold a virtual media event today, Oct. 27, at 8 a.m., from inside the Astronaut Crew Quarters at NASA’s Kennedy Space Center in Florida. Watch live on NASA Television or the agency’s website.

Media may call in to ask the crew questions ahead of their upcoming launch to the International Space Station. Contact the Kennedy newsroom for details on how to participate.

Housed inside the Neil Armstrong Operations and Checkout (O&C) Building, the crew quarters are where the astronauts remain while awaiting launch once they arrive at the Florida spaceport. The facility dates back to the Apollo Program and was also used for missions under the Space Shuttle Program. Inside the crew quarters are 23 bedrooms – each with its own bathroom – and the iconic suit room, where astronauts are helped into their spacesuits before exiting the O&C and making the short journey to the launch pad.

Crew-3 astronauts Chari, Marshburn, Barron, and Maurer are scheduled to lift off aboard a Falcon 9 rocket and Crew Dragon spacecraft from Kennedy’s Launch Complex 39A on Sunday, Oct. 31. Launch is targeted for 2:21 a.m. EDT, and approximately 22 hours later, they will arrive at the orbiting laboratory for a short overlap with the astronauts who flew to the station as part of NASA’s SpaceX Crew-2 mission in April.

Return of Crew-2 astronauts Shane Kimbrough, Megan McArthur, Akihiko Hoshide, and Thomas Pesquet is planned for early November, with a splashdown of Crew Dragon Endeavor at one of seven landing zones off the coast of Florida. Crew-3 astronauts will remain on board for a six-month science mission, living and working as part of what is expected to be a seven-member crew.

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.

Teams from Boeing and United Launch Alliance (ULA) safely returned the CST-100 Starliner to its production facility in Florida on Aug. 19 for continued work on the spacecraft’s service module propulsion system.

The Starliner Orbital Flight Test-2 spacecraft was removed from its Atlas V rocket inside the Vertical Integration Facility at Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida and returned to the Commercial Crew and Cargo Processing Facility on NASA’s Kennedy Space Center.

The team now will perform propulsion system checkouts inside the factory’s hazardous processing area and determine the appropriate vehicle configuration for accessing and analyzing the system further. NASA and Boeing will recommend forward work as part of a formal process designed to aid in determining root cause and remediation steps.

In the weeks ahead, engineering teams from NASA and Boeing will work to diagnose and ultimately resolve a valve issue detected during the Aug. 3 countdown for NASA’s Boeing Orbital Flight Test-2, and resulted in the decision to postpone the launch destined for the International Space Station.

NASA, Boeing, and ULA will establish a new launch date once the issue is resolved.

NASA and Boeing have decided to postpone the launch of Orbital Flight Test-2 to the International Space Station as teams continue work on the CST-100 Starliner propulsion system.

Engineering teams have been working to restore functionality to several valves in the Starliner propulsion system from inside United Launch Alliance’s Vertical Integration Facility that did not open as designed during the launch countdown for the Aug. 3 launch attempt. The valves connect to thrusters that enable abort and in-orbit maneuvering.

“We made a lot of progress to open the valves from inside the Vertical Integration Facility, and the NASA-Boeing teams did a great job doing everything we could to get ready for this launch opportunity,” said Kathryn Lueders, associate administrator for NASA’s Human Exploration and Operations Mission Directorate. “Although we wanted to see Starliner fly in this window, it’s critical that our primary focus is the safety of the crew transportation system – for the safety of the space station and the crew members that will be flying on these vehicles. We’ll only fly this test when we think we are ready, and can complete the mission objectives.”

Inside the VIF, Boeing was able to prompt nine of 13 valves open that previously were in the closed position using commanding, mechanical, electrical and thermal techniques. Teams will now begin the process to move Starliner back to Boeing’s Commercial Crew and Cargo Processing Facility in Florida for deeper-level troubleshooting of four propulsion system valves that remain closed and more detailed analysis on the spacecraft.

“Mission success in human spaceflight depends on thousands of factors coming together at the right time,” said John Vollmer, vice president and program manager, Boeing’s Commercial Crew Program. “We’ll continue to work the issue from the Starliner factory and have decided to stand down for this launch window to make way for other national priority missions.”

NASA, Boeing and ULA will establish a new launch date once the issue is resolved.

NASA, Boeing Make Progress on Starliner Valve Issue

NASA and Boeing continued work over the weekend and Monday morning on the company’s CST-100 Starliner spacecraft service module propulsion system in preparation for the Orbital Flight Test-2 mission to the International Space Station.

Work progressed to restore functionality to several valves in the Starliner propulsion system that did not open as designed during the launch countdown for the Aug. 3 launch attempt. The valves connect to thrusters that enable abort and in-orbit maneuvering.

With the United Launch Alliance (ULA) Atlas V and Starliner in the Vertical Integration Facility (VIF) near Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida, engineering teams are able to power on Starliner allowing the vehicle to receive commands, and have direct access to the spacecraft for troubleshooting.

Inside the VIF, Boeing has been able to command seven of 13 valves open that previously were in the closed position. Test teams are applying mechanical, electrical and thermal techniques to prompt the valves to open, and are moving forward with a systematic plan to open the remainder of the affected valves, demonstrate repeatable system performance, and verify the root cause of the issue before returning Starliner to the launch pad for its Orbital Flight Test-2 mission.

Boeing also has completed physical inspections and chemical sampling on the exterior of a number of the affected valves, which indicated no signs of damage or external corrosion.

In the coming days, NASA and Boeing will continue work to bring all affected valves into the proper configuration. If all valve functionality can be restored and root cause identified, NASA will work with Boeing to determine a path to flight for the important uncrewed mission to the space station.

NASA, Boeing and ULA are assessing the potential for several launch opportunities with the earliest available in mid-August. Any launch date options would protect for the planetary window for the agency’s Lucy mission – the first-ever mission to explore Trojan asteroids.

NASA and Boeing are continuing to work through steps to determine what caused the unexpected valve position indications on the CST-100 Starliner propulsion system during the countdown for its Aug. 3 launch attempt.

Now that the United Launch Alliance Atlas V rocket with the Starliner spacecraft on top has been returned to its Vertical Integration Facility (VIF) at Space Launch Complex-41 on Cape Canaveral Space Force Station, engineers will have direct access to Starliner with the assembly of support structures around the spacecraft’s service module for continued troubleshooting.

Boeing will power up Starliner, allowing the vehicle to receive commands providing the teams with real-time data.

The data will drive any corrective measures that may be necessary to ensure Starliner is ready for launch. When NASA’s Commercial Crew Program and Boeing agree the issue is resolved, a new launch opportunity will be selected, taking into account the readiness of all parties involved and the availability of the International Space Station and its crew to support the spacecraft’s arrival.

NASA and Boeing are continuing to work through steps to determine what caused the unexpected valve position indications on the CST-100 Starliner propulsion system.

The United Launch Alliance Atlas V with the Starliner spacecraft on top will be returned to its Vertical Integration Facility (VIF) at Launch Complex-41 on Cape Canaveral Space Force Station Thursday where engineers will have direct access to Starliner for continued troubleshooting.

The data will drive any corrective measures that may be necessary to ensure Starliner is ready for launch. When NASA’s Commercial Crew Program and Boeing Space agree the issue is resolved, a new launch opportunity will be selected, taking into account the readiness of all parties involved.

“The Boeing and NASA teams are working methodically to understand what caused the valve indications on the Starliner service module propulsion system,” Steve Stich, manager of the Commercial Crew Program, said. “The troubleshooting in the Vertical Integration Facility will help focus on potential causes and next steps before we fly the OFT-2 mission.”

Early in the launch countdown for the Tuesday, Aug. 3 launch attempt, engineers detected indications that not all of Starliner’s propulsion system valves were in the proper configuration needed for launch of the company’s second uncrewed orbital flight test to the International Space Station, a mission designed to test the end-to-end capabilities of the crew-capable system as part of NASA’s Commercial Crew Program.

Mission teams decided to halt the countdown to further analyze the issue, which was conducted later Tuesday via several steps to troubleshoot the incorrect valve indications, including cycling the service module propulsion system valves.

After presenting the data to NASA and Boeing managers, it was decided to relocate the Atlas V and Starliner to the VIF for further inspection and testing where access to the spacecraft is available. Engineering teams have ruled out a number of potential causes, including software, and the direct access is required to continue the assessment.

“This mission is extremely important for the Commercial Crew Program on the path to the Boeing Crewed Flight Test,” Stich said. “We will fly the mission when we are ready. I am extremely proud of the NASA and Boeing teams for their professionalism, perseverance, and methodical approach to solving complex problems.”

NASA and Boeing will take whatever time is necessary to ensure Starliner is ready for its important uncrewed flight test to the space station and will look for the next available opportunity after resolution of the issue.

NASA, Boeing Standing Down on Aug. 4 Starliner Launch Attempt

NASA and Boeing are standing down from the Wednesday, Aug. 4, launch attempt of the agency’s Orbital Flight Test-2 to the International Space Station as mission teams continue to examine the cause of the unexpected valve position indications on the CST-100 Starliner propulsion system.

Early in the launch countdown for the Aug. 3 attempt, mission teams detected indications that not all valves were in the proper configuration needed for launch. Mission teams decided to halt the countdown to further analyze the issue.

NASA and Boeing worked through several steps to troubleshoot the incorrect valve indications, including cycling the service module propulsion system valves, within the current configuration of the Starliner and United Launch Alliance Atlas V rocket at Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida.

Mission teams have decided to roll the Atlas V and Starliner back to the Vertical Integration Facility (VIF) for further inspection and testing where access to the spacecraft is available. Boeing will power down the Starliner spacecraft this evening. The move to the VIF is expected to take place as early as tomorrow.

Engineering teams have ruled out a number of potential causes, including software, but additional time is needed to complete the assessment.

NASA and Boeing will take whatever time is necessary to ensure Starliner is ready for its important uncrewed flight test to the space station and will look for the next available opportunity after resolution of the issue.
