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.

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.

NASA’s Boeing Crew Flight Test astronauts Butch Wilmore, commander, and Suni Williams, pilot, are suited up and on their way to the launch pad for tonight’s launch.

The duo spent about an hour putting on their suits and completing suit leak checks inside the Neil A. Armstrong Operations and Checkout Building at the agency’s Kennedy Space Center in Florida.

After departing the building, Wilmore and Williams waved to family and friends waiting outside before loading into Boeing’s Astrovan.

“Let’s fly” Wilmore said.

The nine-mile drive will take the astronauts to the launch pad at nearby Space Launch Complex-41 at Cape Canaveral Space Force Station.

Wilmore and Williams are the first crew to fly aboard Boeing’s Starliner as part of the agency’s Commercial Crew Program. Liftoff to the International Space Station is scheduled for 10:34 p.m. EDT. The crew is expected to arrive at the orbiting laboratory for rendezvous and docking at 12:46 a.m. Wednesday, May 8.

Wilmore and Williams will spend about a week at the space station before the crew capsule makes a parachute and airbag-assisted landing in the southwestern United States.

Once the flight test is complete, NASA will begin the final process of certifying Starliner and its systems for regular human spaceflight launches.

NASA astronauts Butch Wilmore and Suni Williams are being outfitted in their Boeing spacesuits inside the crew suit-up room at the Neil A. Armstrong Operations and Checkout Building at the agency’s Kennedy Space Center in Florida as preparations continue for the agency’s Boeing Crew Flight Test.

The Boeing Starliner suits are specifically tailored for tonight’s launch.

  • The blue suits are lighter and more flexible than previous spacesuits, with advanced materials and featuring zippers at the elbows and knees, which enables flexibility when the astronauts are standing or seated.
  • The helmet and visor are attached to the suit instead of detachable.
  • Touchscreen-sensitive gloves
  • Suit has vents but can still pressurize immediately.

The full suit, which includes shoes and accessories, weighs about 20 pounds – close to 10 pounds lighter than suits worn by space shuttle astronauts.

NASA’s Boeing Crew Flight Test astronaut Butch Wilmore participates in a traditional game of cards after suit-up and final fit checks inside the Neil A. Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida on Monday, May 6, 2024

Once suited, Wilmore and Williams play the ritual card game that occurs before any human spaceflight mission launching from the Florida spaceport. The point of the game is that the commander must use up all his or her bad luck before the launch, so the crew can only leave for the pad when the commander loses.

Launch is scheduled for 10:34 p.m. EDT from Space Launch Complex-41 at nearby Cape Canaveral Space Force Station.

NASA astronauts Butch Wilmore and Suni Williams will be the first to fly aboard Boeing’s Starliner spacecraft to the International Space Station, and the name of the spacecraft ferrying them to the orbiting laboratory holds a special place in Williams’ heart.

Williams named the crew capsule Calypso in 2019 to pay tribute to the explorer Jacques Cousteau, who sailed across the world on his own ship named bearing the same name. Cousteau’s goal was to learn about the ocean and teach others about the wonders of the sea. Williams believes Starliner can do the same for space.

The Starliner spacecraft, with a diameter of 15 feet (4.56 meters), can carry up to four astronauts, or a mix of crew and cargo, for NASA missions to low Earth orbit for the agency’s Commercial Crew Program.

The spacecraft, on a United Launch Alliance Atlas V rocket, is scheduled for liftoff at 10:34 p.m. EDT Monday, May 6, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.
