Boeing's Starliner all packed up to return to Earth from ISS today

Update for 12:20 a.m. EDT on Sept. 7: Boeing's first Starliner spacecraft to carry astronauts landed safely, without its astronaut crew, early Saturday after a relatively smooth undocking, reentry and landing. Read our full story and see landing video .

Boeing's Starliner capsule is ready to come home at long last.

The two NASA astronauts who rode Starliner to the International Space Station (ISS), Butch Wilmore and Suni Williams, "have finished packing Starliner with cargo and configuring its cabin for return," NASA officials announced in an update on Thursday (Sept. 5).

"The duo closed Starliner's hatch for the final time Thursday afternoon, readying the spacecraft for its uncrewed departure," they added. You can watch the Starliner undocking and landing live , courtesy of NASA TV, starting at 5:45 p.m. EDT (2145 GMT).

As that update noted, Williams and Wilmore won't be coming down with Starliner; the capsule will land uncrewed just after midnight Saturday (Sept. 7) in New Mexico's White Sands Space Harbor, if all goes according to plan.

The touchdown will wrap up Starliner's first-ever astronaut mission, Crew Flight Test (CFT), which launched on June 5 and arrived at the ISS a day later. Starliner suffered several issues before docking, however — notably, helium leaks and the failure of five of its 28 reaction control system (RCS) thrusters.

CFT was supposed to last just 10 days or so, but NASA kept extending the test mission to study the helium leaks and thruster issue in more detail. Ultimately, the agency decided that flying Williams and Wilmore home on Starliner posed an unacceptable risk , so the duo will stay in orbit for a while longer — until February 2025, when they'll come home on a SpaceX Crew Dragon capsule.

That Crew Dragon hasn't left the ground yet; it's scheduled to lift off on Sept. 24, carrying NASA astronaut Nick Hague and cosmonaut Aleksandr Gorbunov to the ISS. (Crew Dragon missions usually carry four astronauts, but this one had to make room for Williams and Wilmore on the downward leg.)

Saturday morning's touchdown will be the third for Starliner to date. The first came in May 2019, after an unsuccessful uncrewed flight to the ISS; the capsule suffered several glitches and failed to meet up with the orbiting lab as planned. The second landing, in May 2022, wrapped up a successful uncrewed test mission to the ISS.
