After Years of Trouble, Boeing Repeats Launch of Starliner Spacecraft for NASA

Published:

Boeing’s second likelihood at a do-over is off to a successful start as Starliner, its space taxi, launched to orbit on Thursday.

The spacecraft was built for NASA to take astronauts to and from the International Space Station. But before it could do this, it has to finish a test flight without astronauts to point out that its systems all work properly.

“Today feels really good and we’ve quite a lot of confidence within the vehicle,” Mark Nappi, vp and program manager for the business crew program at Boeing, said during a news conference a few hours after the launch.

Two thrusters failed during a maneuver to place Starliner in a stable orbit, however the spacecraft was capable of routinely adjust with its remaining thrusters, and it proceeded on target. Engineers are investigating what went flawed.

Two previous attempts to undertake that preparatory journey — the primary in December 2019 and the second in August 2021 — were each marred by serious technical problems. The setbacks have also cost Boeing a whole bunch of thousands and thousands of dollars.

Boeing is catching as much as SpaceX, the newer space company founded by Elon Musk that has already carried five NASA crews to orbit previously two years.

A second transportation option for NASA also offers resilience in case either spacecraft suffers an accident.

Otherwise, NASA would must rely again on Russia’s Soyuz capsules, which were the one ride to orbit for American astronauts for nearly a decade. Collaboration between america and Russia on the space station has change into politically complicated after Russia invaded Ukraine earlier this 12 months.

At 6:54 p.m. Eastern time, the engines of an Atlas 5 rocket roared from a launching pad at Cape Canaveral Space Force Station in Florida, lifting Starliner toward the sky. Thirty-two minutes later, it was safely in orbit.

Thursday’s launch was a relief for Boeing and NASA officials. The countdown and liftoff unfolded without unpleasant surprises. The one glitch occurred through the first of Starliner’s thruster firings, needed to provide the spacecraft its final push to orbit.

In the back of the spacecraft are 4 pods, each containing a cluster of three thrusters. For the orbital insertion maneuver, which lasted about 40 seconds, one thruster in each pod began firing.

In one in every of the pods, the thruster began firing, then stopped after a second, Mr. Nappi said. The Starliner’s flight control system switched to a second thruster in the identical pod.

“It fired for about 25 seconds, after which it shut down,” Mr. Nappi said. “Again, the flight control system took over and did what it was alleged to. It went to a 3rd thruster, and we had a successful orbital insertion.”

Steve Stich, the manager of NASA’s business crew program, said even when the third thruster in that pod failed, “I think we could complete the mission just high-quality with the remaining clusters.”

Engineers will see in the event that they can get the malfunctioning thrusters working again, and Mr. Nappi said the opposite systems on Starliner seem like working well.

“So the spacecraft is in excellent condition,” he said.

Just over 24 hours after launch, Starliner is scheduled to dock on the International Space Station.

Although this mission will not be carrying any astronauts, one in every of Starliner’s seats is filled by a mannequin named Rosie the Rocketeer.

There’s also greater than 800 kilos of cargo aboard, mostly food and supplies for the space station crew, but in addition some memorabilia. The spacecraft is to bring back almost 600 kilos of cargo from the space station.

After 4 or five days attached to the space station, Starliner is to return to Earth, at one in every of five locations within the western United States. While most American astronaut capsules have splashed down within the ocean — including SpaceX’s Crew Dragon — Starliner parachutes onto land and sets down atop airbags.

If all goes well, the flight will provide NASA with sufficient data to certify that the spacecraft can safely carry people into space. An illustration flight with two or three astronauts aboard could launch as soon as the tip of the 12 months.

Through the first uncrewed test flight in December 2019, problems began almost immediately upon reaching orbit.

A software error caused the Starliner’s clock to be set to the flawed time. That caused the onboard computer to try to maneuver the spacecraft to where it thought the vessel needs to be. The firing of the thrusters used up much of the propellant, and plans for Starliner to dock on the space station were called off.

While troubleshooting that problem, Boeing engineers discovered a second flaw that might have caused the flawed thrusters to fireplace because the capsule prepared for re-entry, potentially resulting in the destruction of the spacecraft. They fixed that software flaw while Starliner orbited the Earth, and the capsule landed safely at White Sands, N.M.

Those problems put a hold on what would have been the following step: an illustration flight with astronauts aboard. NASA told Boeing that it needed to repeat the uncrewed test flight, at Boeing’s cost.

Boeing spent greater than a 12 months revamping and retesting the software, and in August last 12 months, Starliner was back on the launching pad at Cape Canaveral Space Force Station in Florida, on top of a second Atlas 5 rocket.

The countdown began, but needed to be halted. Flight managers discovered that 13 valves in Starliner’s propulsion system had did not open.

Boeing then spent about eight months investigating the corrosion that had caused the valves to stay shut. Boeing swapped out the service module — the piece of Starliner below the capsule that houses the propulsion system — with one which had been planned for the following mission.

NASA hired two corporations to take astronauts to and from the station: SpaceX and Boeing. On the time of Boeing’s test flight in 2019, it seemed that Starliner would beat out SpaceX’s Crew Dragon capsule for the primary mission with astronauts.

But with Starliner remaining on the bottom, SpaceX has since launched seven Crew Dragon missions with astronauts. Along with the five missions for NASA, two others carried private residents to orbit.

SpaceX’s missions also seem like significantly inexpensive than Boeing’s. Still, NASA officials say that they’re committed to Starliner and that having two systems provides competition, innovation and suppleness.
