Boeing’s Starliner to attempt second uncrewed test flight to space station

·4-min read

Aerospace giant Boeing is set to attempt its second uncrewed flight to the International Space Station (ISS) as part of a test to show it can get to and from the orbiting lab safely.

The CST-100 Starliner capsule will carry supplies and test equipment to the space station but the main aim of the mission will be to demonstrate that the spacecraft can launch, dock, re-enter the Earth’s atmosphere and perform a desert landing safely.

Nasa and Boeing are targeting July 30 for the lift-off, which will take place at the Kennedy Space Centre at Cape Canaveral in Florida.

If the mission is successful, it will pave the way for Starliner to become a “taxi service” for Nasa, ferrying astronauts to and from the space station.

In 2019, Starliner failed to rendezvous with the space station during its first uncrewed test flight after being plagued by software issues.

But the spacecraft was able to successfully return to Earth two days after launch, landing at the White Sands Space Harbour in New Mexico.

Over the past 18 months, Boeing and Nasa teams worked together to resolve the issues, which involved taking 80 corrective actions.

Following Starliner’s flight readiness test last week, Kathy Lueders, Nasa’s director of spaceflight, said: “After reviewing the team’s data, and the readiness of all the parties, everybody said ‘go’ for the launch.”

Meanwhile rival aerospace company SpaceX has already taken three astronaut crews to the space station, using its Crew Dragon capsule.

Last year Elon Musk’s firm made history when it transported Nasa astronauts Robert Behnken and Douglas Hurley to the space station and back, becoming the first private company to send humans into low-Earth orbit.

Since ending its Space Shuttle programme in 2011, Nasa has depended on Russia’s space agency Roscosmos to send its astronauts to the space station.

In 2014, Nasa awarded SpaceX and Boeing contracts to provide crewed launch services to the space station as part of its Commercial Crew Programme.

Starliner will be hoisted into space on an Atlas V rocket operated by American space launch company United Launch Alliance (ULA).

In addition to supplies and equipment, also travelling on the spacecraft will be a dummy named Rosie the Rocketeer.

She will be strapped in Starliner’s commander’s seat and her main aim will be to help maintain the spacecraft’s centre of gravity.

Rosie will be dressed in Boeing’s bright blue spacesuit, the same one astronauts will wear when they are flying on the Starliner.

Like SpaceX’s Crew Dragon, the Starliner capsule is reusable but is said to have the capability to fly up to 10 missions, compared to Crew Dragon’s five.

But while SpaceX has opted for ocean landings, Boeing’s spacecraft will touch down on land at one of its five sites in the western US.

Boeing said this landing method “allows for quicker access to crew and cargo, as well as makes turning around capsules for other missions more efficient”.

Meanwhile, Nasa has already selected the first two groups of astronauts to travel on the Starliner.

Mike Fincke, Nicole Mann and Barry “Butch” Wilmore are expected to be the first astronauts to launch into space aboard the Starliner as part of the Crew Flight Test mission.

This will essentially be a demonstration mission to show Boeing’s ability to ferry astronauts to the space station and back safely.

If successful, astronauts Sunita Williams, Josh Cassada and Jeanette Epps will then launch on Boeing’s first ever operational crewed mission to the space station.
