Boeing Starliner arrives safely at the ISS, but it sprung more leaks along the way

Boeing’s Starliner has completed its first crewed journey to the International Space Station (ISS), carrying NASA astronauts Butch Wilmore and Suni Williams following its dramatic launch yesterday. The Starliner docked with this ISS at 1:34 p.m. ET, after a journey of just over 24 hours from its launch from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.

The journey did not go entirely smoothly, however, as there were several helium leaks from the Starliner. One of these was a leak previously identified on the ground, which NASA and Boeing investigated before launch and determined was not serious enough to pose a threat to the mission. However, two new leaks were identified during the flight in addition to this original leak.

“Prior to crew sleep, mission teams identified three helium leaks in the spacecraft,” NASA wrote in an update. “One of these was previously discussed before flight along with a management plan, and the other two occurred when the spacecraft arrived in orbit. To monitor and manage these leaks, the three helium manifolds were closed in flight during the crew’s sleep period and were all reopened ahead of rendezvous and docking operations.”

With the Starliner now docked, the teams will continue to monitor the leaks to watch their severity.

There was also an issue with the first attempt to dock the Starliner to the space station, as there was a problem with Starliner’s reaction control thrusters. Five of the thrusters, which are necessary to precisely line up the spacecraft with the station’s docking port, went out during the flight. The team then performed a hotfire test and was able to reignite four of these five thrusters, which were enough to get the spacecraft to dock safely.

The hatch of the ISS will open shortly, allowing Wilmore and Williams to enter the station and greet the crew there. More information is expected to come from NASA soon about the issues with the Starliner and the severity of the leaks detected, though during the livecast NASA engineers gave assurances that the spacecraft was safe and stable, though they would need to observe it overnight to learn more.

NASA reveals date for attempted return flight of troubled Starliner

Boeing's Starliner spacecraft docked at the space station.

NASA is targeting Friday, September 6, for the return flight of Boeing Space’s troubled Starliner spacecraft, the agency revealed on Thursday.

The vehicle will come home from the International Space Station (ISS) nearly three months later than originally planned and without the crew that it arrived with. The flight, the outcome of which could determine the Starliner’s future, is expected to take about six hours, NASA said in a blog post on Thursday.

Starliner astronauts to return to Earth in SpaceX Dragon next year

NASA’s Boeing Crew Flight Test astronauts (from top) Butch Wilmore and Suni Williams pose on June 13, 2024 for a portrait inside the vestibule between the forward port on the International Space Station’s Harmony module and Boeing’s Starliner spacecraft.

Two NASA astronauts who have been stuck in orbit for over two months after the Boeing Starliner spacecraft they traveled in developed a fault on the outward journey will return to Earth in a SpaceX Dragon craft next year. Butch Wilmore and Suni Williams were aboard the Starliner for what was supposed to be a one-week test flight, but issues with the craft's thrusters have forced it to remain docked at the International Space Station for testing. Now, the Starliner will return home uncrewed, and the astronauts will stay on the station to complete a six-month stint there.

This is a major setback for both NASA and Boeing, as NASA has repeatedly stressed its desire for multiple commercial options for travel to the space station in addition to the SpaceX Dragon. But engineers have struggled to replicate and solve the issues with the Starliner from the ground, and the agency says it is prioritizing the safety of Wilmore and Williams by keeping them aboard the station.

NASA to announce decision about stuck Starliner astronauts tomorrow

Boeing’s Starliner spacecraft that launched NASA’s Crew Flight Test astronauts Butch Wilmore and Suni Williams to the International Space Station is pictured docked to the Harmony module’s forward port on Wednesday, July 3, 2024.

NASA is holding a press conference Saturday, August 24, to announce a decision on how to bring home two astronauts who have been stuck on the International Space Station.

After been more than two months since the Boeing Starliner launched on what was supposed to be a one-week mission. Following both helium leaks (which were known about before the launch) and problems with the thrusters (which weren't), the Starliner's two test pilots -- NASA astronauts Butch Wilmore and Suni Williams -- have stayed aboard the International Space Station as NASA and Boeing officials assess if and when it will be safe for them to travel back to Earth.
