In less than 24 hours, NASA astronauts Butch Wilmore and Suni Williams will be the first to launch aboard Boeing’s Starliner spacecraft to the International Space Station as part of the agency’s Commercial Crew Program.

NASA, Boeing, and ULA (United Launch Alliance) are ready for the Saturday, June 1, launch of the agency’s Boeing Crew Flight Test. The partners made the announcement during a prelaunch media briefing held earlier from NASA’s Kennedy Space Center in Florida.

“I’m very proud of the teams who have worked really hard the last two and a half weeks to prepare for launch,” said Steve Stich, manager, NASA’s Commercial Crew Program. “We’re really ready to go fly.”

Launch weather officers with the U.S. Space Force’s 45th Weather Squadron predict a 90% chance of favorable weather conditions for tomorrow’s launch, with ground winds and the cumulus cloud rule being the primary weather concerns.

The integrated ULA Atlas V rocket and Starliner spacecraft stack rolled out to the pad at Space Launch Complex-41 at Cape Canaveral Space Force Station on May 30 in preparation for liftoff. Meanwhile, Wilmore and Williams have remained in preflight quarantine inside the Neil A. Armstrong Operations and Checkout Building following their return to the Florida spaceport on May 28.

“We look forward to flying this mission. This is a test flight; we know we’re going to learn things,” said Mark Nappi, vice president and program manager, Commercial Crew Program, Boeing. “We are going to improve, and that improvement starts with the Starliner-1 mission and it will be even better than the mission we’re about to fly.”

The mission will send Wilmore and Williams to the orbiting laboratory for about a week before Starliner makes a parachute and airbag-assisted landing in the southwestern United States.

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 will carry four astronauts, or a mix of crew and cargo, for NASA missions to low Earth orbit.

Managers from NASA, Boeing, and ULA (United Launch Alliance) hosted a media teleconference to discuss ongoing work ahead of sending NASA astronauts Butch Wilmore and Suni Williams to the International Space Station as part of the agency’s Boeing Crew Flight Test. 

The media event provided an update on a valve ULA replaced on the Centaur upper stage of the Atlas V rocket, as well as a small helium leak in the spacecraft’s service module, and a propulsion system assessment to understand potential helium system impacts on some Starliner return scenarios. 

Listen to a replay of the media teleconference on the agency’s YouTube channel. 

Wilmore and Williams are the first to launch aboard Boeing’s Starliner on an Atlas V rocket. 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. 

The crew remains in quarantine in preparation for the launch. NASA, Boeing, and ULA also will participate in a Delta-Agency Flight Test Readiness Review on Wednesday, May 29, to evaluate the work performed since the last launch attempt on May 6. 

Liftoff is scheduled for 12:25 p.m. Saturday, June 1, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. After successful completion of the flight test, NASA will begin the final process of certifying Starliner and its systems for crewed rotation missions to the space station.

NASA, Boeing, and ULA (United Launch Alliance) teams will take additional time to work through spacecraft closeout processes and flight rationale before proceeding with the launch of the agency’s Boeing Crew Flight Test. The teams now are targeting a launch no earlier than 3:09 p.m. EDT Saturday, May 25, for the flight test carrying NASA astronauts Butch Wilmore and Suni Williams to the International Space Station.

The additional time allows teams to further assess a small helium leak in the Boeing Starliner spacecraft’s service module traced to a flange on a single reaction control system thruster. Pressure testing performed on May 15 on the spacecraft’s helium system showed the leak in the flange is stable and would not pose a risk at that level during the flight. The testing also indicated the rest of the thruster system is sealed effectively across the entire service module. Boeing teams are working to develop operational procedures to ensure the system retains sufficient performance capability and appropriate redundancy during the flight. As that work proceeds, NASA’s Commercial Crew Program and the International Space Station Program will take the next few days to review the data and procedures to make a final determination before proceeding to flight countdown.

The ULA Atlas V rocket and Boeing’s Starliner remain in the Vertical Integration Facility at Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida. The NASA, Boeing, and ULA teams remain committed to ensuring a safe Starliner flight test.

Wilmore and Williams will remain quarantined in Houston as prelaunch operations progress. They will fly back to NASA’s Kennedy Space Center in Florida closer to the new launch date. The duo is the first to launch aboard Starliner to the space station as part of the agency’s Commercial Crew Program. The astronauts will spend about a week at the orbiting laboratory before returning to Earth and making a parachute and airbag-assisted landing in the southwestern United States.

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.

NASA, Boeing, and ULA (United Launch Alliance) teams continue working remaining open tasks in preparation for the agency’s Boeing Crew Flight Test to the International Space Station. The teams now are targeting a launch date of no earlier than 4:43 p.m. EDT on Tuesday, May 21, to complete additional testing.

On May 11, the ULA team successfully replaced a pressure regulation valve on the liquid oxygen tank on the Atlas V rocket’s Centaur upper stage. The team also performed re-pressurization and system purges, and tested the new valve, which performed normally.

Starliner teams are working to resolve a small helium leak detected in the spacecraft’s service module traced to a flange on a single reaction control system thruster. Helium is used in spacecraft thruster systems to allow the thrusters to fire and is not combustible or toxic.

NASA and Boeing are developing spacecraft testing and operational solutions to address the issue. As a part of the testing, Boeing will bring the propulsion system up to flight pressurization just as it does prior to launch, and then allow the helium system to vent naturally to validate existing data and strengthen flight rationale. Mission teams also completed a thorough review of the data from the May 6 launch attempt and are not tracking any other issues.

The Atlas V and Starliner remain in the Vertical Integration Facility at Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida.

NASA astronauts Butch Wilmore and Suni Williams, still in preflight quarantine, returned to Houston on May 10 to spend extra time with their families as prelaunch operations progress. The duo will fly back to NASA’s Kennedy Space Center in Florida in the coming days.

Wilmore and Williams are the first to launch aboard Boeing’s Starliner to the space station as part of the agency’s Commercial Crew Program. The astronauts will spend about a week at the orbiting laboratory before returning to Earth and making a parachute and airbag-assisted landing in the southwestern United States.

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.

Space physics and life support maintenance topped the schedule at the end of the week for the Expedition 71 crew as the Starliner astronauts return to Houston. 3D printing and cargo operations also rounded out the operations aboard the International Space Station.

The coldest place in the universe may be the Cold Atom Lab located aboard the orbital outpost’s Destiny laboratory module. NASA Flight Engineer Mike Barratt opened up the quantum physics research device Friday morning and inspected its cables and ports as part of broader science hardware replacement work. The ultra-cold laboratory chills atoms to near absolute zero to observe their fundamental characteristics and quantum behaviors.

Barratt then joined NASA Flight Engineers Tracy C. Dyson and Matthew Dominick as they continued life support maintenance in the Tranquility module. Barratt activated the water processing assembly then reinstalled module components to their normal configuration in Tranquility. Dominick and Dyson spent the day in the module replacing hardware that supports the water recovery system which is part of the orbital outpost’s Waste and Hygiene compartment, or bathroom.

NASA Flight Engineer Jeanette Epps assisted Dyson at the end of the day finalizing cleanup activities in Tranquility after the advanced orbital plumbing work was complete. Epps began her shift in the Kibo laboratory module replacing obsolete gas bottles with new types of gas bottles in the Common Gas Supply Equipment rack. The gas supply hardware supplies gases including argon, helium, and carbon dioxide fueling research racks and their experiments inside Kibo.

Working in the orbiting lab’s Roscosmos segment, Commander Oleg Kononenko checked Soyuz communication systems, inspected video equipment, and cleaned vents on broadband hardware. Flight Engineer Nikolai Chub worked on a 3D printing experiment testing the device’s controller and software while printing an object. Chub also stowed trash and obsolete gear inside the Progress 86 resupply ship that is due to undock at the end of the month. Flight Engineer Alexander Grebenkin spent his day checking smoke detectors in the Nauka science module.

On the ground at NASA’s Kennedy Space Center in Florida, preparations continue ahead of the agency’s Boeing Crew Flight Test launch to the microgravity laboratory. NASA astronauts Butch Wilmore and Suni Williams, still in quarantine ahead of the flight test, will return to Houston this weekend as work progresses on a valve replacement on the United Launch Alliance Atlas V rocket Centaur upper stage. Crew will return to NASA Kennedy prior to the next launch opportunity, which is targeted for no earlier than 6:16 p.m. EDT on Friday, May 17, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.

Wilmore and Williams are the first to launch aboard Boeing’s Starliner to the space station as part of the agency’s Commercial Crew Program. The astronauts will spend about a week at the orbiting laboratory before returning to Earth and making a parachute and airbag-assisted landing in the southwestern United States.

After successful completion of the mission, NASA will finalize certification of Starliner and its systems for crewed rotation missions to the space station. The Starliner capsule, with a diameter of 15 feet (4.56 meters) 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.

NASA’s Boeing Crew Flight Test now is targeted to launch no earlier than 6:16 p.m. EDT Friday, May 17, to the International Space Station. Following a thorough data review completed on Tuesday, ULA (United Launch Alliance) decided to replace a pressure regulation valve on the liquid oxygen tank on the Atlas V rocket’s Centaur upper stage.

ULA plans to roll the rocket, with Boeing’s Starliner spacecraft, back to its Vertical Integration Facility at Cape Canaveral Space Force Station in Florida on Wednesday, May 8, to begin the replacement. The ULA team will perform leak checks and functional checkouts in support of the next launch attempt.

The oscillating behavior of the valve during prelaunch operations, ultimately resulted in mission teams calling a launch scrub on May 6. After the ground crews and astronauts Butch Wilmore and Suni Williams safely exited from Space Launch Complex-41, the ULA team successfully commanded the valve closed and the oscillations were temporarily dampened. The oscillations then re-occurred twice during fuel removal operations. After evaluating the valve history, data signatures from the launch attempt, and assessing the risks relative to continued use, the ULA team determined the valve exceeded its qualification and mission managers agreed to remove and replace the valve.

Mission managers discussed the details leading to the decision to scrub the May 6 launch opportunity during a news conference shortly after the scrub call at NASA’s Kennedy Space Center in Florida.

Wilmore and Williams will remain in crew quarters at NASA Kennedy in quarantine until the next launch opportunity. The duo will be the first to launch aboard Starliner to the space station as part of the agency’s Commercial Crew Program.
