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.

It was a light duty day aboard the International Space Station for four Expedition 71 astronauts as they await the launch and arrival of Boeing’s Crew Flight Test. The orbital outpost’s three cosmonauts had their day full as they kept up lab maintenance and researched a variety of microgravity phenomena.

NASA Flight Engineers Tracy C. Dyson and Mike Barratt kicked off Monday morning with a series of biomedical tests to help doctors understand how living in space affects the human body. Dyson first collected her saliva samples then stowed them in a science freezer for later analysis. Afterward, she drew her blood then processed those samples with assistance from Barratt before spinning them in a centrifuge then stowing them in a science freezer.

Next, Barratt joined NASA Flight Engineer Matthew Dominick and set up in-ear sensors that will monitor an astronaut’s sleep patterns in space. Researchers will record the data and compare it to a crew member’s sleep patterns on Earth before and after a space mission. The Sleep in Orbit investigation will help doctors learn how sleep differs on and off the Earth and promote an astronaut’s cognitive well-being.

All three astronauts then joined NASA Flight Engineer Jeanette Epps, who had the entire day off, and relaxed the rest of their shift while also conducting in their daily exercise sessions.

The quartet will work half-a-day on Tuesday then go to bed early and get a good night’s sleep before the arrival of Boeing’s Starliner spacecraft carrying NASA astronauts Butch Wilmore and Suni Williams. The Commercial Crew duo is scheduled to launch aboard Starliner atop United Launch Alliance’s Atlas V rocket at 10:34 p.m. EDT today from Florida. Starliner is due to dock to the orbital lab’s forward port on the Harmony module at 12:46 a.m. on Wednesday. Watch live on the NASA+ streaming service via the web or the NASA app. Mission coverage also will air live on NASA Television,  YouTube, and on the agency’s website. Learn how to stream NASA TV through a variety of platforms including social media.

Roscosmos’ three cosmonauts Oleg Kononenko, Nikolai Chub, and Alexander Grebenkin had a full day on Monday tending to ongoing research and ensuring the upkeep of the space station. Kononenko spent his shift servicing life support gear and science hardware. Chub cleaned airducts in the Nauka science module then photographed the condition of windows in the Zvezda service module. Grebenkin worked throughout the day on orbital plumbing duties and computer maintenance while also studying how international crews and controllers con improve communications.
