NASA and Boeing leadership are adjusting the return to Earth of the Starliner Crew Flight Test spacecraft with agency astronauts Butch Wilmore and Suni Williams from the International Space Station. The move off Wednesday, June 26, deconflicts Starliner’s undocking and landing from a series of planned International Space Station spacewalks while allowing mission teams time to review propulsion system data. Listen to a full replay of the June 18 media briefing where NASA and Boeing leadership discussed the ongoing efforts.

“We are taking our time and following our standard mission management team process,” said Steve Stich, manager of NASA’s Commercial Crew Program. “We are letting the data drive our decision making relative to managing the small helium system leaks and thruster performance we observed during rendezvous and docking. Additionally, given the duration of the mission, it is appropriate for us to complete an agency-level review, similar to what was done ahead of the NASA’s SpaceX Demo-2 return after two months on orbit, to document the agency’s formal acceptance on proceeding as planned.”

A media telecon with mission leadership will follow the readiness review’s conclusion, and the agency will share those details as they are solidified. Boeing’s Starliner spacecraft remains cleared for return in case of an emergency on the space station that required the crew to leave orbit and come back to Earth.

Mission managers are evaluating future return opportunities following the station’s two planned spacewalks on Monday, June 24, and Tuesday, July 2.

“Starliner is performing well in orbit while docked to the space station,” said Stich. “We are strategically using the extra time to clear a path for some critical station activities while completing readiness for Butch and Suni’s return on Starliner and gaining valuable insight into the system upgrades we will want to make for post-certification missions.”

Wilmore and Williams remain integrated with the Expedition 71 crew, assisting with station operations as needed and completing add-on in-flight objectives for NASA certification of Starliner.

“The crew’s feedback has been overwhelmingly positive, and they know that every bit of learning we do on the Crew Flight Test will improve and sharpen our experience for future crews,” said Mark Nappi, vice president and program manager, Boeing’s Starliner Program.

The crew is not pressed for time to leave the station since there are plenty of supplies in orbit, and the station’s schedule is relatively open through mid-August.

Orbiting Earth as part of the nine-person crew of the International Space Station, NASA astronauts Butch Wilmore and Suni Williams continue testing Boeing’s Starliner spacecraft as part of its first flight with astronauts. The testing is part of the data collection on the Starliner system for certification by NASA for regular crewed mission to the orbital complex.

As part of NASA’s Boeing Crew Flight Test, Wilmore and Williams, along with teams on the ground, are stepping through numerous flight objectives following arrival of Starliner to the space station on June 6, including:

  • Powering the spacecraft down into a minimal power mode, which it will enter during operational missions while the crew works aboard station, and then powering it up again;
  • Conducting “safe haven” checks to show the spacecraft can support a crew with its own air and consumables during in an emergency on the station;
  • Performing a habitability study, along with astronauts Tracy Dyson and Matthew Dominick,to evaluate seating positions and other factors, such as air circulation for a four-person crew;
  • Evaluating spacesuit and seat-fits, as well as checkouts of the service module’s batteries.

Meanwhile, ground teams continue to assess and monitor Starliner’s performance and planning for return of the mission no earlier than Tuesday, June 18, pending weather and spacecraft readiness. Starliner is cleared for crew emergency return scenarios from space station, if needed, in accordance with the flight rules.

While Starliner remains docked to station, ground teams are continuing to evaluate propulsion system in-flight observations.

“Butch and Suni are doing great aboard station as ground teams continue digging into the details of Starliner’s on-orbit, rendezvous, and docked performance,” said Steve Stich, manager, NASA’s Commercial Crew Program. “We expected to do a lot of valuable learning on this test flight, and I am extremely proud of how the NASA and Boeing teams are working together to ensure we can safely execute the return portion of the mission.”

One of Starliner’s aft-facing reaction control system (RCS) thrusters, capable of about 85 pounds of thrust, remains de-selected as teams continue to evaluate its performance. Ground teams plan to fire all 28 RCS thrusters after undocking to collect additional data signatures on the service module thrusters before the hardware is expended. As part of normal operations, the service module separates from crew module on return, so NASA and Boeing will gather as much data as possible to aid in system assessments.

Teams currently are assessing what impacts, if any, five small leaks in the service module helium manifolds would have on the remainder of the mission. Engineers evaluated the helium supply based on current leak rates and determined that Starliner has plenty of margin to support the return trip from station. Only seven hours of free-flight time is needed to perform a normal end of mission, and Starliner currently has enough helium left in its tanks to support 70 hours of free flight activity following undocking. While Starliner is docked, all the manifolds are closed per normal mission operations preventing helium loss from the tanks.

Engineers also are evaluating an RCS oxidizer isolation valve in the service module that is not properly closed. Ground teams performed a successful propulsion system valve checkout on Sunday. All other oxidizer and fuel valves within the service module were cycled normally. The suspect oxidizer isolation valve was not cycled in the recent checkout. It will remain commanded closed for the remainder of the mission while ground teams continue to evaluate its data signatures. The crew module propulsion valves, which are part of an independent system that steers the capsule in the last phase of flight before landing, also were successfully cycled, and all those valves are performing as designed.

Mission managers are continuing to work through the return plan, which includes assessments of flight rationale, fault tolerance, and potential operational mitigations for the remainder of the flight. NASA and Boeing will hold a pre-departure media teleconference to provide additional updates before Starliner undocks from station.

With launch and docking already completed, the last remaining dynamic phase of the mission will come at the end of the flight test when Starliner will undock from the orbiting laboratory and then adjust its orbit to move away from the space station. The spacecraft, with Wilmore and Williams aboard, will perform a deorbit burn before entering the atmosphere and landing in the southwestern United States under parachutes and landing airbags to complete the flight.

As part of the agency’s Commercial Crew Program, the mission is the first crewed flight for the Starliner spacecraft. Learn more about the mission by following the commercial crew blog,@commercial_crew on X, and on Facebook.

The United Launch Alliance Atlas V rocket booster has separated from the Centaur upper stage carrying Boeing’s Starliner spacecraft. The Centaur will continue to help propel Boeing’s Starliner to a suborbit before the spacecraft boosts itself to orbit, bringing it closer to the International Space Station. 

Measuring 10 feet in diameter and 41.5 feet in length, the Centaur upper stage uses liquid hydrogen and liquid oxygen to power its twin Aerojet Rocketdyne RL10A-4-2 engines. The burn of the Centaur’s dual engines is expected to last a little more than seven minutes before engine cutoff and separation from Starliner. Following separation, the crew capsule carrying NASA astronauts Butch Wilmore and Suni Williams will be on its own for the remainder of the journey to the space station. 

Following its separation, the Atlas Centaur will land in the ocean near Australia. 

NASA Television will provide continuous coverage leading up to docking at the space station and through hatch opening and welcome remarks.
