During a media teleconference Friday, leaders from NASA and Boeing provided an update about Starliner’s Crew Flight Test. The integrated Starliner team continues to evaluate the spacecraft’s propulsion system performance and complete other forward work before scheduling undocking from the International Space Station. Listen to a full replay of the teleconference.

“Our goal is to bring Butch and Suni home aboard Boeing’s spacecraft, and we are working to confirm Starliner will perform as designed to return them safely to Earth,” said Ken Bowersox, associate administrator, NASA’s Space Operations Mission Directorate, NASA Headquarters in Washington. “Space station gives us the luxury of time, allowing us to look at data we gathered on the way uphill and conduct some additional testing. We’re still in the middle of a test mission, and we want to spend more time with the data before we make the final call to put the crew aboard the spacecraft for return.”

NASA and Boeing will conduct additional ground testing at White Sands Test Facility in New Mexico to better understand the spacecraft’s thruster performance. This testing will expose Starliner’s thrusters to flight-like pulse counts and thermal conditions for ground teams to inspect and analyze. The data collected also will help determine system improvements for future post-certification missions to station.

“We spent a lot of time working to determine whether we could get meaningful data from a ground hot fire to better inform our decision making in flight, and I am extremely proud of our integrated NASA and Boeing teams for coming up with some innovative options and leveraging testing plans that were already in place for future missions,” said Steve Stich, manager of NASA’s Commercial Crew Program. “Based on the continued performance of Starliner while docked, we are working with station to extend the certification of several components beyond a 45-day mission duration, if needed, so our engineering teams can take the time they need while Butch and Suni support various in-orbit activities that are critical for sustaining station operations and research.”

Engineering teams are working to finalize testing plans and a timeline for the additional ground testing, which should occur over the next two weeks. They are taking advantage of the extra time by gathering as much data as possible while docked to station, considering the service module will not be recovered at the end of the mission.

Since Starliner’s arrival on June 6 with NASA astronauts Butch Wilmore and Suni Williams aboard, mission teams have been working to complete open work related to managing five small leaks in the spacecraft’s service module helium manifolds while reaffirming the health of the spacecraft’s reaction control system thrusters. Starliner remains available in case of an emergency on the space station that would require the crew to leave orbit immediately and return to Earth.

In addition to monitoring the hardware in orbit, which is operating normally in a docked state, NASA and Boeing continue testing and analysis on the ground by exploring potential causes for the helium system leaks and analyzing instrumentation data on Starliner’s thrusters. Engineers are working to gauge potential helium leak rates that may occur after undocking, validate operational mitigations for use in flight as needed, and explore fault tree considerations beyond what the teams have already gathered from the flight data.

They also are evaluating recent ground test results that showed better than expected performance of Starliner’s thruster instrumentation. Based upon these results, engineering teams have confidence that Starliner’s thruster pressure transducers are not overheating in flight and causing premature deselects of the thrusters in orbit, which was initially considered to be a possibility. Meanwhile, simulated propulsion system contingency scenarios continue to be worked in the lab to ensure expected performance of Starliner’s backup systems and thruster combinations for use during the return if needed.

Once all the necessary ground testing and associated data analysis is complete, leaders from NASA’s Commercial Crew and International Space Station Programs and Boeing will conduct an agency-level review. During the review, senior agency leaders and mission managers will discuss their findings and options with the broader NASA community, including international partners, to formally document the agency’s acceptance of Starliner’s flight plan and evaluate future return opportunities.

NASA plans to host a televised media briefing following the agency review to discuss the next steps ahead of Starliner’s return. The agency will share details on that briefing once it is finalized.

Wilmore and Williams continue to provide additional crew time and valuable contributions aboard the space station, assisting with spacewalks and science investigations while helping ground teams collect critical data for post-certification, long-duration Starliner flights to the orbiting complex.

NASA astronauts Suni Williams and Butch Wilmore successfully completed an integrated crew exercise simulation that moves Boeing’s Starliner spacecraft one step closer to its first flight with astronauts to the International Space Station.

Targeted for launch no earlier than mid-April 2024, NASA’s Boeing Crew Flight Test (CFT) will fly Williams and Wilmore to the orbiting laboratory for about up to two weeks. They will evaluate Starliner and its systems before returning to Earth in the Western United States. Liftoff will be aboard a United Launch Alliance (ULA) Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida.

Completing the simulation Wednesday at NASA’s Kennedy Space Center in Florida marks another milestone toward CFT launch. The integrated exercise involved participation from the flight crew, NASA, Boeing, and ULA, and allowed teams to rehearse prelaunch operations beginning roughly four hours before a targeted liftoff. The exercise began with Wilmore and Williams walking through suit-up procedures inside the Astronaut Crew Quarters in NASA Kennedy’s Neil Armstrong Operations and Checkout building.

Following this, they took an elevator down to the ground floor and exited the same double doors they will on launch day where their crew transportation vehicle was waiting to transport them to the launch pad. The crew and support teams then convoyed to the launch pad, where Williams and Wilmore supported operations from the white room – an area at the end of the launch tower’s crew access arm that will provide access to the spacecraft. The remainder of the rehearsal involved the crew traveling back to NASA Kennedy to support from Boeing’s Mission Control Center.

Over the next several weeks, teams will run through additional simulations focused on each phase of the mission. Some upcoming milestones include CFT certification, fueling Starliner with propellants, and stacking Starliner on the Atlas V rocket before rolling out to the launch pad in preparation for liftoff.

Starliner completed two uncrewed flight tests: Orbital Flight Test-2, which launched from Cape Canaveral and completed its space station mission in May 2022, and Orbital Flight Test-1, which provided teams with additional flight data in December 2019. During these two uncrewed missions, the end-to-end capabilities of the spacecraft were successfully tested.

A modified parachute system for Boeing’s Starliner spacecraft for NASA’s Commercial Crew Program was tested over the Arizona desert on Jan. 9. Parachute deployment and a soft landing of the test article were visually confirmed. Preliminary data analysis of this two-parachute test suggest the primary test objectives were met. Engineering teams will continue to review the results, inspect the test parachutes, and work to complete system certification in the weeks ahead.

In the meantime, NASA and Boeing are proceeding with preparations for Starliner to carry astronauts for the first time to the International Space Station during the Crew Flight Test, currently slated to launch no earlier than mid-April on a mission lasting about 10 days.

The drop test, which used a Starliner parachute system attached to a dart-shaped sled the same weight as a Starliner, was performed to confirm the functioning of a redesigned and strengthened soft link joint that is part of the network of lines connecting the parachutes to the spacecraft. The test also validated a change to strengthen one textile joint in the parachute, increasing overall parachute robustness. As with other capsules, Starliner relies on parachutes to land safely when it returns to Earth.

A C-130 cargo aircraft from NASA’s Wallops Flight Facility in Virgina, carried the test article and parachutes high above the U.S. Army’s Yuma Proving Ground in Arizona before releasing them. Engineering teams, CFT astronauts Butch Wilmore, Suni Williams and Starliner-1 astronaut Mike Fincke watched from the drop zone below. The Starliner main parachutes were lifted from the test article using flight-like pilot parachutes before inflating fully to slow the test dart to the same soft-landing velocity experienced by the Starliner spacecraft in flight.

Starliner completed two uncrewed flight tests including Orbital Flight Test-2, which docked to the space station on May 21, 2022.

NASA and Boeing now are targeting no earlier than Friday, July 21, for the agency’s Boeing Crew Flight Test (CFT) to the International Space Station, pending coordination for the U.S Eastern Range availability.

The new target date provides NASA and Boeing the necessary time to complete subsystem verification testing and close out test flight certification products and aligns with the space station manifest and range launch opportunities.

The goal of CFT is to test the end-to-end capabilities of the Starliner system with crew onboard, including the United Launch Alliance Atlas V rocket, from prelaunch to docking and undocking to landing and recovery. Following a successful test flight, Boeing will work to finalize operational readiness for its post-certification missions and NASA will begin the final process of certifying the Starliner spacecraft and systems for regular, crewed missions to the space station.

Certification Process
Approximately 90% of the certification products required for the flight test are complete. NASA and Boeing anticipate closure on remaining CFT certification products this spring after ongoing verification testing of several subsystems is complete, including testing on the spacecraft’s backup manual flight mode for added redundancy in cases of emergency.

Starliner Status
The Starliner spacecraft build is complete. The team is now working through final interior closeouts of the spacecraft and wrapping up integrated testing. The loading of cargo apart from some late-stow items also is complete. The next major hardware milestones are specific to the launch campaign timeline, such as spacecraft fueling and rolling out to the launch site.

Atlas V Status
NASA completed its rocket readiness assessment, which evaluates all CFT launch vehicle segment flight critical items prior to integration activities. All rocket hardware is at Cape Canaveral Space Force Station in Florida, awaiting processing ahead of rocket stacking at the launch site.

Crew Readiness
The NASA astronauts who will fly on CFT recently completed the critical Crew Equipment Interface Test. Conducted in two parts during February and March, the test allowed astronauts to perform hands-on training with the tools, equipment and hardware they will use on orbit. In the first part, they worked with the Starliner team to perform in-cabin checkouts, including adjusting the spacecraft seats, inspecting spacecraft interfaces, examining cargo, and conducting floor panel and side hatch operations. The second part of the test included the astronauts maneuvering inside the cabin with cargo installed in the spacecraft.
