The astronauts say they’re feeling optimistic about today’s launch.

Once suited, Wilmore and Williams will 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 launch pad once the commander loses.

The duo have been in quarantine for more than a month.

Launch is scheduled for 10:52 a.m. EDT from Space Launch Complex-41 at nearby Cape Canaveral Space Force Station.

Boeing’s Starliner spacecraft will send two of the agency’s astronauts to the International Space Station as part of NASA’s Commercial Crew Program. Butch Wilmore, commander, and Suni Williams, pilot, will launch aboard Starliner on a ULA (United Launch Alliance) Atlas V rocket at 10:52 a.m. EDT from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.

The crew flight test is Boeing’s second flight to the International Space Station and third Starliner flight test overall, following Orbital Flight Test-2, an uncrewed mission in May 2022, and Orbital Flight Test, an uncrewed mission in December 2019.

The crew flight test mission makes history in several ways. As the first crewed launch of Boeing’s Starliner spacecraft, Williams is the first female astronaut to fly on the first flight of a crewed spacecraft. The launch also marks the first crewed launch on the ULA Atlas V rocket and the first crewed launch on an Atlas-family class rocket since Gordon Cooper on the last Mercury program flight aboard “Faith 7” in May 1963.

Weather is looking beautiful for NASA’s Boeing Crew Flight Test to send two of the agency’s astronauts to the International Space Station. Launch weather officers with the U.S. Space Force’s 45th Weather Squadron predict a 90% chance of favorable weather conditions at the launch pad for a liftoff, scheduled for 10:52 a.m. EDT.

Boeing’s Starliner spacecraft, carrying NASA astronauts Butch Wilmore, commander, and Suni Williams, pilot, on a ULA (United Launch Alliance) Atlas V rocket will launch from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.

Following a poll for fueling by NASA, Boeing, and ULA, the Atlas V rocket now is being filled with liquid oxygen in the first stage and a combination of liquid oxygen and hydrogen in the Centaur upper stage. RP-1, a rocket-grade kerosene, was loaded into the first stage previously.

The Starliner spacecraft, named Calypso, can fly autonomously or be steered manually and is expected to rendezvous and dock with the space station at approximately 12:15 p.m., Thursday, June 6. Wilmore and Williams will spend about a week at the orbiting laboratory before the spacecraft 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 crewed rotation missions to the space station as part of the agency’s Commercial Crew Program.

Teams at NASA and Boeing confirmed Monday the company’s Starliner spacecraft, ULA (United Launch Alliance) Atlas V rocket, and ground support equipment are healthy and ready for the next launch attempt. The first Starliner flight with NASA astronauts Butch Wilmore and Suni Williams, known as NASA’s Boeing Crew Flight Test, is targeted to liftoff at 10:52 a.m. EDT Wednesday, June 5, to the International Space Station for about a one week stay aboard the microgravity laboratory.

Work at the launch pad at Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida was completed June 2 to change out and test a failed power distribution source that halted a launch attempt on June 1. The Starliner mission management team reviewed multiple aspects of the replacement and troubleshooting steps and polled “go” to proceed during a detailed session as they continue to prep the teams and hardware for the June 5 opportunity.

“I really appreciate all the work by the NASA, Boeing, and ULA teams over the last week,” said Steve Stich, manager of NASA’s Commercial Crew Program. “In particular, the ULA team worked really hard to quickly learn more about these issues, keep our NASA and Boeing teams informed, and protect for this next attempt. We will continue to take it one step at a time.”

The weather forecast continues to call for favorable conditions, with U.S. Space Force meteorologists from the 45th Weather Squadron predicting a 90% chance of acceptable conditions at launch time. The ascent corridor and onshore winds weather also is forecast to be acceptable in the unlikely case of an emergency abort during the launch.

Wilmore and Williams continue preparing for launch with proficiency training. The two remain quarantined at Kennedy Space Center in Florida ahead of liftoff.

NASA, Mission Partners Target June 5 Crew Flight Test Launch

NASA’s Boeing Crew Flight Test mission teams are preparing to support a launch at 10:52 a.m. EDT Wednesday, June 5, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida on a mission of about a week to the International Space Station.

Technicians and engineers with ULA (United Launch Alliance) worked overnight and on Sunday to assess the ground support equipment at the launch pad that encountered issues during the countdown and scrubbed the June 1 launch attempt. The ULA team identified an issue with a single ground power supply within one of the three redundant chassis that provides power to a subset of computer cards controlling various system functions, including the card responsible for the stable replenishment topping valves for the Centaur upper stage. All three of these chassis are required to enter the terminal phase of the launch countdown to ensure crew safety.

On Sunday, the chassis containing the faulty ground power unit was removed, visually inspected, and replaced with a spare chassis. No signs of physical damage were observed. A full failure analysis of the power unit will be performed to better understand root cause. Meanwhile, ULA has completed functional checkouts of the new chassis and the cards, and all hardware is performing normally.

The mission managers have opted for the next launch attempt on June 5. The U.S. Space Force’s 45th Weather Squadron predicts a 90% chance of favorable weather conditions, with the cumulus cloud rule being the primary weather concern. Another opportunity is available at 10:29 a.m., Thursday, June 6.

NASA astronauts Barry “Butch” Wilmore and Suni Williams, the crew of the flight test who will be the first to launch aboard Boeing’s Starliner spacecraft, remain in quarantine at NASA’s Kennedy Space Center and will take part in pilot proficiency and other training activities leading up to launch.
