Boeing's Starliner capsule docks with space station in uncrewed flight

CAPE CANAVERAL, Fla. (Reuters) - Boeing's
new Starliner crew capsule docked for the first time with the
International Space Station (ISS) on Friday, completing a major
objective in a high stakes do-over test flight into orbit without
astronauts aboard.
The rendezvous of the gumdrop-shaped CST-100 Starliner with the orbital
research outpost, currently home to a seven-member crew, occurred nearly
26 hours after the capsule was launched from Cape Canaveral U.S. Space
Force Base in Florida.
Starliner lifted off on Thursday atop an Atlas V rocket furnished by the
Boeing-Lockheed Martin joint venture United Launch Alliance (ULA) and
reached its intended preliminary orbit 31 minutes later despite the
failure of two onboard thrusters.
Boeing said the two defective thrusters posed no risk to the rest of the
spaceflight, which comes after more than two years of delays and costly
engineering setbacks in a program designed to give NASA another vehicle
for sending its astronauts to and from orbit.
Docking with ISS took place at 8:28 p.m. EDT (0028 GMT Saturday) as the
two vehicles flew 271 miles (436 km) over the south Indian Ocean off the
coast of Australia, according to commentators on a live NASA webcast of
the linkup.
It marked the first time spacecraft from both of NASA's Commercial Crew
Program partners were physically attached to the space station at the
same time. A SpaceX Crew Dragon capsule has been docked to the space
station since delivering four astronauts to ISS in late April.

Much was riding on the outcome, after an ill-fated first test flight in
late 2019 nearly ended with the vehicle's loss following a software
glitch that effectively foiled the spacecraft's ability to reach the
space station.
Subsequent problems with Starliner's propulsion system, supplied by
Aerojet Rocketdyne, led Boeing to scrub a second attempt to launch the
capsule last summer.
Starliner remained grounded for nine more months while the two companies
sparred over what caused fuel valves to stick shut and which firm was
responsible for fixing them, as Reuters reported last week.
Boeing said it ultimately resolved the issue with a temporary workaround
and plans a redesign after this week's flight.
Besides seeking a cause of thruster failures shortly after Thursday's
launch, Boeing said that it was monitoring some unexpected behavior
detected with Starliner's thermal-control system, but that the capsule's
temperatures remained stable.

"This is all part of the learning process for
operating Starliner in orbit," Boeing mission commentator Steve
Siceloff said during the NASA webcast.
The capsule is scheduled to depart the space station
on Wednesday for a return-flight to Earth, ending with an
airbag-softened parachute landing in the New Mexico desert.
A success is seen as pivotal to Boeing as the Chicago-based company
scrambles to climb out of successive crises in its jetliner business
and its space defense unit. The Starliner program alone has cost
nearly $600 million in engineering setbacks since the 2019 mishap.
If all goes well with the current mission, Starliner could fly its
first team of astronauts to the space station as early as the fall.
For now, the only passenger was a research dummy, whimsically named
Rosie the Rocketeer and dressed in a blue flight suit, strapped into
the commander's seat and collecting data on crew cabin conditions
during the journey, plus 800 pounds (363 kg) of cargo to deliver to
the space station.
The orbital platform is currently occupied by a crew of three NASA
astronauts, a European Space Agency astronaut from Italy and three
Russian cosmonauts.
Russia's Roscosmos space agency Director General Dmitry Rogozin
noted the docking in a social media post on Saturday, adding: "The
station is not in danger. Aboard the Russian segment of the ISS
there is order."
Since resuming crewed flights to orbit from American soil in 2020,
nine years after the space shuttle program ended, the U.S. space
agency has had to rely solely on the Falcon 9 rockets and Crew
Dragon capsules from Elon Musk's company SpaceX to fly NASA
astronauts.
Previously the only other option for reaching the orbital laboratory
was by hitching rides aboard Russian Soyuz spacecraft.
