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.

Boeing’s Crew Flight Test on Starliner Docks to Station

Boeing's Starliner spacecraft with two NASA astronauts aboard approaches the space station for an autonomous docking as it orbited 257 miles above the South Pacific Ocean.
Boeing’s Starliner spacecraft with two NASA astronauts aboard approaches the space station for an autonomous docking as it orbited 257 miles above the South Pacific Ocean.

NASA astronauts Butch Wilmore and Suni Williams, aboard Boeing’s Starliner spacecraft, successfully docked to the International Space Station at 1:34 p.m. EDT. Starliner launched on a United Launch Alliance Atlas V rocket at 10:52 a.m., June 5 from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.

During flight, Wilmore and Williams successfully performed manual piloting demonstrations of Starliner and completed a sleep period. Prior to crew sleep, mission teams identified three helium leaks in the spacecraft. One of these was previously discussed before flight along with a management plan, and the other two occured when the spacecraft arrived in orbit. To monitor and manage these leaks, the three helium manifolds were closed in flight during the crew’s sleep period and were all reopened ahead of rendezvous and docking operations. After docking, all Starliner manifolds are closed per normal plans.

As Starliner began its approach to the space station, five reaction control system thrusters failed off during flight. Mission teams performed a series of hot-fire tests which re-enabled four of the thrusters while the crew manually piloted the spacecraft at the station’s 200-meter hold point. After re-selecting four of the thrusters, Starliner had the fault tolerance required to approach the space station for docking. At the 10-meter hold point, the mission team completed system readiness evaluations and proceeded with docking.

Starliner’s hatch opening will begin about 3:20 p.m., with welcome remarks to follow.

NASA will continue coverage on NASA+, NASA Television, the NASA app, YouTube, and the agency’s website. Learn how to stream NASA TV through a variety of platforms including social media.

NASA will host a post-docking media conference at approximately 5 p.m. with the following participants:

  • NASA Associate Administrator Jim Free
  • Steve Stich, manager, NASA’s Commercial Crew Program
  • Jeff Arend, manager for systems engineering and integration, NASA’s International Space Station Office
  • Mark Nappi, vice president and program manager, Commercial Crew Program, Boeing

NASA’s arrival coverage of Boeing’s Starliner spacecraft to the International Space Station is now underway on NASA+, NASA Television, the NASA app, YouTube, and the agency’s website. Docking is scheduled at approximately 12:15 p.m. EDT Thursday, June 6.

NASA astronauts Butch Wilmore and Suni Williams launched safely on the Starliner spacecraft on a United Launch Alliance Atlas V rocket at 10:52 a.m. June 5 from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.

The Starliner crew continues to make their way to the space station. During flight, Wilmore and Williams successfully performed manual piloting demonstrations of Starliner and completed a sleep period. Prior to crew sleep, mission teams identified three helium leaks in the spacecraft. One of these was previously discussed before flight along with a management plan, and the other two are new since the spacecraft arrived in orbit. To monitor and manage these leaks, the three helium manifolds were isolated. Those manifolds have all been reopened prior to a Starliner height adjust burn, called NHPC. All affected manifolds will remain open for rendezvous and docking operations.

Following in-flight reviews of the mission and helium leaks, the Starliner and International Space Station mission management teams are “go” to proceed with space station arrival. The flight control team will continue to monitor the leak rates in Starliner’s propulsion system. After docking, all of Starliner manifolds will be closed per normal plans. All other Starliner systems are functioning normally.

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.
