NASA and Boeing teams continue analyzing data from recent ground and spacecraft testing as they evaluate the Starliner spacecraft’s propulsion system during NASA’s Boeing Crew Flight Test mission.

Teams are taking their time to analyze the results of recent docked hot-fire testing, finalize flight rationale for the spacecraft’s integrated propulsion system, and confirm system reliability ahead of Starliner’s return to Earth from the International Space Station.

Forward work for the team also includes finalizing the spacecraft’s undocking procedures and operational mitigations that could be used in flight, if needed, to build further confidence in the system. Meanwhile, Starliner ground and mission support teams are continuing to prepare for undocking by participating in integrated simulations with space station operations teams.

Following the completion of Starliner’s return planning, which is expected to continue into next week, more information will be shared about the agency’s return readiness review preparations and subsequent media briefing. As always, astronaut safety remains the top priority for both NASA and Boeing.

While engineers conduct their spacecraft studies on Earth, NASA astronauts Butch Wilmore and Suni Williams are closely following the ground team’s progress while aboard the station. The duo has integrated into the daily workload of the orbiting laboratory, giving the station a crew of nine as their mission overlaps with Expedition 71.

The astronauts worked primarily on lab upkeep aboard the orbiting outpost on Wednesday. Wilmore spent time inspecting advanced plumbing hardware then packed the life support components for return to Earth. Williams set up high-definition video gear inside the Columbus laboratory module then inspected a bar code reader and radio frequency hardware. Wilmore and Williams also partnered up and organized cargo  inside the Tranquility module before calling into a Boeing mission controllers conference.

Engineering teams with NASA and Boeing completed a hot fire test of the Starliner spacecraft’s reaction control system jets on July 27 to evaluate the spacecraft’s propulsion system. NASA astronauts Butch Wilmore and Suni Williams, assigned to the agency’s Boeing Crew Flight Test, were seated inside the docked spacecraft during the test as part of preparations before their return aboard Starliner from the International Space Station.

The test involved firing 27 of the spacecraft’s 28 jets for short bursts, moving through them one at a time to check thruster performance and helium leak rates. Preliminary results show all the tested thrusters are back to preflight levels based on thrust and chamber pressure.

As part of the test configuration, all helium manifolds, which control and direct the flow of helium, were opened allowing engineers to continue evaluation of Starliner’s helium supply and leak rates. The teams verified Starliner continues to show the margin needed to support a return trip from the station. Following the test, the helium manifolds were closed and will remain closed until Starliner activates its propulsion system ahead of undocking. Teams also will verify the helium leak rate before Starliner undocks.

Teams are taking their time to analyze the results of recent docked hot-fire testing, finalize flight rationale for the spacecraft’s integrated propulsion system, and confirm system redundancy ahead of Starliner’s return to Earth from the International Space Station.

While ground teams work to finalize Starliner’s return to Earth, Wilmore and Williams continue to work alongside the Expedition 71 crew, assisting with science investigations and maintenance activities. On July 29, Wilmore and Williams entered their spacecraft and checked its water systems, called down to Boeing mission personnel for a conference, and put on their space suits long enough to perform a pressure test. Wilmore started his morning in the Harmony module, assembling the BioServe centrifuge as Williams reviewed procedures for operating the Astrobee free-flying robotic assistants.

Astronauts Butch Wilmore and Suni Williams, crew members of NASA’s Boeing Crew Flight Test mission, performed a host of research activities and other roles aboard the International Space Station. Wilmore and Williams give the microgravity laboratory a complement of nine people working through daily tasks.

On Monday, Wilmore and Williams reviewed the procedures for using the Fluid Systems Servicer, which drains, purges, and circulates fluids on systems aboard the space station. Wilmore then refilled coolant loops in the water pump assembly located in the Columbus module. Tuesday saw the pair take turns during the morning pedaling on an exercise cycle while attached to heart and breathing sensors that measured their aerobic capacity. The duo then split up as Wilmore serviced a pair of research freezers that preserve scientific samples and Williams installed hardware on an experiment that explores atmospheric reentry and thermal protection systems.

The seven-member Expedition 71 crew joined the two Boeing Crew Flight Test astronauts to practice an emergency drill in collaboration with mission controllers. The teams aboard the orbital outpost and on the ground coordinated communications and reviewed procedures in the unlikely event of a pressure leak, chemical leak, or fire aboard the space station. Following that, Wilmore and Williams spoke to reporters from the space station, answering questions about their mission and the Starliner vehicle. NASA and Boeing managers also discussed the Crew Flight Test mission with the media in an audio teleconference afterward. Watch the crew news conference here and listen to the media briefing here. The duo also completed life support work refilling temperature loops with water in the Tranquility module’s internal thermal control system.

Advanced biology research also was underway aboard the orbiting lab on Thursday with astronauts exploring how living in space affects the human body and mind. Williams extracted DNA to identify microbe samples collected from station water systems. Results from the genetic biotechnology experiment may improve ways to keep crews healthy and spacecraft systems clean on future missions.

NASA astronaut Michael Barratt also assisted Wilmore, who spent all day servicing a pair of spacesuits in the Quest airlock. The duo cleaned the suits’ cooling loops and checked the communication systems ahead of a spacewalk planned for July 29.

NASA astronauts Butch Wilmore and Suni Williams held a virtual question and answer session with media on May 1, from inside the Astronaut Crew Quarters at NASA’s Kennedy Space Center in Florida ahead of their launch to the space station. 

“We’ve been through training and we have our fingerprints on every single procedure that exists for this spacecraft,” said Wilmore. “We’re fully trained in all aspects of Starliner.”

Wilmore and Williams have quarantined inside the Neil A. Armstrong Operations and Checkout Building since they arrived at the Florida spaceport April 25.  

The Operations and Checkout Building dates back to the Apollo program and was used for missions under the Space Shuttle Program. Located on the third floor, the crew quarters consists of 23 bedrooms, each with its own bathroom. The area also includes the suitup room, where teams help astronauts into their spacesuits before they exit the building and enter a vehicle to take them to the launch pad. 

Wilmore and Williams will be the first to fly aboard Boeing’s Starliner spacecraft, launching on a United Launch Alliance Atlas V rocket to the International Space Station. The astronauts will spend about a week at the orbiting laboratory before the crew capsule makes a parachute and airbag-assisted landing in the southwestern United States. 

“We feel very safe and very comfortable when this spacecraft flies,” said Williams. “This is where we’re supposed to be.”

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. The Starliner capsule, with a diameter of 15 feet (4.56m) and the capability to steer automatically or manually, will carry four astronauts, or a mix of crew and cargo, for NASA missions to low Earth orbit. 

Launch is scheduled for 10:34 p.m. EDT Monday, May 6, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.
