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.

We have liftoff! The United Launch Alliance Atlas V rocket, carrying Boeing’s Starliner spacecraft and NASA astronauts Butch Wilmore, commander, and Suni Williams, pilot, are on a course to the International Space Station.
The crew is on a roughly 25.5-hour journey with rendezvous and docking expected at 12:15 p.m. EDT, Thursday, June 6.
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.
Next up is Max Q, or the moment of peak aerodynamic pressure on the rocket.
Launch coverage on NASA+ will end shortly after Starliner orbital insertion, happening about 30 minutes from now. NASA Television will provide continuous coverage leading up to docking at the space station and through hatch opening and welcome remarks.

Inside Starliner for this mission is about 759 pounds of cargo, which includes food, clothing, exercise gear, medical supplies, photo and media equipment, vehicle supplies and tools, and other items. A thumb drive containing about 3,500 images of artwork from children in 35 states and 66 different countries is also set to launch aboard Starliner tonight.
Wilmore is flying with two gold rings he had made for his father and brother that resemble the U.S. Navy astronaut pilot wing pin. He also brought shirts from his alma maters, Tennessee Technological University and the University of Tennessee. Williams brought shirts from the U.S. Naval Academy and the Sunita L. Williams Elementary School in Needham, Massachusetts. She also has a diver pin and two dog tags from her Labrador retrievers.
At 10:52 a.m. EDT, a United Launch Alliance Atlas V rocket will launch the Starliner crew capsule from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. Following a roughly 25-hour journey, Starliner will rendezvous and dock with the space station at 12:15 p.m. Thursday, June 6.

We’re less than three hours away from NASA astronauts Butch Wilmore and Suni Williams heading to the International Space Station.
Wilmore and Williams just arrived at the crew access tower at Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida and will soon head into the White Room. The environmentally controlled chamber at the outer end of the access arm platform is where astronauts prepare to enter Boeing’s Starliner spacecraft.
The astronauts also made some last minute phone calls before launch.
While in the White Room, the crew will make any last-minute adjustments before launch. Technicians also will complete a series of checkouts before Wilmore enters the capsule, followed by Williams.
The Starliner spacecraft is set to launch at 10:52 a.m. EDT on a United Launch Alliance Atlas V rocket. Weather continues to hold at 90% chance of favorable conditions for liftoff.

The astronauts say they’re feeling optimistic about today’s launch.
Once suited, Wilmore and Williams usually 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. However during today’s game, they played rock, paper, scissors.
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.

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.
