NASA will fly two astronaut test pilots aboard the agency’s Boeing Crew Flight Test (CFT) mission to the International Space Station, where they will live and work off the Earth for about two weeks.
CFT commander Barry “Butch” Wilmore, whom NASA assigned to the prime crew in October 2020, will join NASA astronaut Suni Williams, who will serve as pilot. Williams previously served as the backup test pilot for CFT while assigned as commander of NASA’s Boeing Starliner-1 mission, Starliner’s first post-certification mission. As CFT pilot, Williams takes the place of NASA astronaut Nicole Mann, originally assigned to the mission in 2018. NASA reassigned Mann to the agency’s SpaceX Crew-5 mission in 2021.
NASA astronaut Mike Fincke, whom the agency previously assigned as the Joint Operations Commander for CFT, will now train as the backup spacecraft test pilot and remains eligible for assignment to a future mission. Fincke’s unique expertise will continue to benefit the team as he retains his position as flight test lead, filling a vital role in Starliner certification.
Meteorologists with the U.S. Space Force 45th Weather Squadron now predict an 80% chance of favorable weather for today’s uncrewed launch of NASA’s Boeing Orbital Flight Test-2 (OFT-2) to the International Space Station. Liftoff is scheduled for 6:54 p.m. EDT from Cape Canaveral Space Force Station in Florida.
The primary weather concerns for launch day are the cumulus and anvil cloud rules violations during the instantaneous launch window.
Boeing’s CST-100 Starliner spacecraft, atop a United Launch Alliance Atlas V rocket, will lift off from Space Launch Complex-41. Live launch coverage begins at 6 p.m. EDT on NASA TV, the NASA app, and the agency’s website.
On Wednesday, May 4, Boeing’s CST-100 Starliner was joined with the rocket that will launch the spacecraft on its way to the International Space Station on an uncrewed flight test for NASA’s Commercial Crew Program.
During the operation, Starliner rolled out of the Commercial Crew and Cargo Processing Facility (C3PF) at NASA’s Kennedy Space Center in Florida and made its way to Space Launch Complex-41 (SLC-41) at Cape Canaveral Space Force Station in preparation for the company’s second uncrewed Orbital Flight Test (OFT-2)
Starliner was raised and carefully placed onto the rocket and now is fully assembled and ready for an integrated systems test, a tip-to-tail electrical check of the 172-foot-tall Atlas V and Starliner stack.
OFT-2 is scheduled to launch Thursday, May 19, to demonstrate the system’s human transportation capabilities.
About 24 hours after launch, Starliner will rendezvous and dock to the space station and then return to Earth five to 10 days later. The test is the last flight before the Starliner system launches American astronauts on the Crew Flight Test (CFT) to the microgravity laboratory – the spacecraft’s first flight test with crew on board. Potential launch windows for CFT are under review and will be determined after a safe and successful OFT-2.
NASA and Boeing will hold a joint media teleconference at noon EDT on Tuesday, May 3, to discuss the agency’s Boeing Orbital Flight Test (OFT-2) mission and provide an update on spacecraft readiness.
The teleconference includes the following participants:
Kathryn Lueders, associate administrator, Space Operations Mission Directorate, NASA Headquarters
Steve Stich, manager, Commercial Crew Program, NASA’s Kennedy Space Center in Florida
Joel Montalbano, manager, International Space Station Program, NASA’s Johnson Space Center in Houston
Michelle Parker, vice president and deputy general manager, Space and Launch, Boeing
Mark Nappi, vice president and program manager, CST-100 Starliner, Boeing
OFT-2 is scheduled to launch on Thursday, May 19, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. Boeing’s uncrewed CST-100 Starliner will launch atop a United Launch Alliance Atlas V rocket for its flight test to the International Space Station as part of NASA’s Commercial Crew Program.
Starliner is expected to arrive at the space station for docking about 24 hours later with more than 500 pounds of NASA cargo and crew supplies. After a successful docking, Starliner will spend five to 10 days aboard the orbiting laboratory before returning to Earth in the western United States. The spacecraft will return with nearly 600 pounds of cargo, including reusable Nitrogen Oxygen Recharge System (NORS) tanks that provide breathable air to station crew members.
Media wishing to participate in the OFT-2 mission overview news teleconference must RSVP by 11 a.m., Tuesday, May 3, by emailing the Kennedy newsroom at email@example.com.
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.
NASA and Boeing are holding a Flight Readiness Review (FRR) today at the agency’s Kennedy Space Center in Florida in preparation for the Orbital Flight Test-2 (OFT-2) mission to the International Space Station as part of the agency’s Commercial Crew Program.
Teams have gathered to hear presentations from key mission managers as part of an in-depth assessment on the readiness of flight for Boeing’s CST-100 Starliner spacecraft and systems, mission operations, support functions and readiness of the space station program to support Starliner’s mission to the microgravity laboratory.
Kathryn Lueders, associate administrator for NASA’s human exploration and operations, is leading the meeting. The senior Boeing official at the review is John Vollmer, vice president and program manager for Boeing’s Commercial Crew Program. The meeting will conclude with a poll of all members of the review board.
At 6 p.m. or one hour after the readiness review, NASA and Boeing will hold a media teleconference to discuss the review and status to flight with the following participants:
Kathryn Lueders, associate administrator, Human Exploration and Operations Mission Directorate at NASA
Steve Stich, manager, NASA’s Commercial Crew Program
Joel Montalbano, manager, NASA’s International Space Station Program
John Vollmer, vice president and program manager, Boeing Commercial Crew Program
Launch of Starliner is targeted at 2:53 p.m. EDT Friday, July 30, on a United Launch Alliance Atlas V rocket from Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida; the spacecraft will rendezvous and dock with the orbiting laboratory about a day later.
The flight test will provide valuable data NASA will review as part of the process to certify Boeing’s crew transportation system is as safe as possible for carrying astronauts to and from the space station.
NASA and Boeing have completed reviews of the company’s uncrewed Orbital Flight Test (OFT) that flew in December 2019 and are working toward a plan to refly the mission to the International Space Station as part of the agency’s Commercial Crew Program.
The joint NASA-Boeing Independent Review team completed their final assessments of issues that were detected during the first test flight of Boeing’s CST-100 Starliner spacecraft. Following this conclusion, the team identified a total of 80 recommendations that Boeing, in collaboration with NASA, is addressing. A launch date has not been set yet for the second flight test, dubbed OFT-2.
Boeing’s CST-100 Starliner spacecraft atop a United Launch Alliance Atlas V rocket rolled out of the Vertical Integration Facility at Cape Canaveral Air Force Station’s Space Launch Complex 41 earlier today. Starliner now stands poised at the launch pad awaiting its maiden flight on Boeing’s uncrewed Orbital Flight Test to the International Space Station as part of NASA’s Commercial Crew Program. Liftoff is scheduled for 6:36 a.m. EST Friday, Dec. 20. The flight test will provide valuable data on the end-to-end performance of the Atlas V rocket, Starliner spacecraft, and ground systems, as well as in-orbit, docking, and landing operations. The data will be used as part of NASA’s process of certifying Boeing’s crew transportation system for carrying astronauts to and from the space station.
Meteorologists with the U.S. Air Force 45th Weather Squadron continue to predict an 80% chance of favorable weather for launch on Friday morning. Primary concerns for launch day are the Cumulus Cloud Rule and User Ground Winds violations during the instantaneous launch window.
