NASA's Butch Wilmore and Watch Chrysalis OnlineSuni Williams are world-renowned as the "stranded astronauts": Though they didn't endure the longest spaceflight, it would certainly seem that way based on news coverage. 

Perhaps it was their association with Boeing, the beleaguered aerospace companythat built the spaceship that made their story go viral. The veteran astronauts took Starliner to the International Space Station last summer. The pair was only supposed to be gone for eight days. Instead, the two were laid over in spacefor nine months. 

Starliner experienced propulsion problems during their arrival last June, so NASA made a game-time decisionto send the ship back to Earth emptyand arrange for a different capsule to bring them home. In the interim, Wilmore and Williams were integrated as members of Crew-9, the team staffing the space station. Starliner's uncrewed landing, for what it's worth, touched down without a hitch. 

The day of the astronauts' return finally has arrived, with the U.S. space agency moving up the schedule a tad to avoid some inclement weatherexpected later in the week. The SpaceX Dragon capsule bringing them home departed from the space station on schedule at 1:05 a.m. ET on Tuesday, March 18, and the crew is on its way back home.

How to watch those "stuck" astronauts return

Wilmore and Williams are now en route to a splashdown landingslated for 5:57 p.m. ET today, March 18. NASA plans to provide live coverageof the event, resuming with the ship's reentry into Earth's atmosphere. People can tune in for the broadcast at about 4:45 p.m. ET on March 18.

Though nine months is indeed a long time to be away from the planet, it's not the longest time any astronaut has spent in orbit. Just prior to the Starliner saga, NASA astronaut Frank Rubio experienced his own delayed return in 2023. Due to a tiny but concerning leakin the Russian Soyuz capsule set to bring him home, the two space agencies decided to arrange a different ride for Rubio and two cosmonauts to be safe. 

The change of plans led to Rubio spending over a year in space — 371 days to be exact — the longest single spaceflightfor an American. The Russian cosmonaut Valeri Polyakov still owns the record for most consecutive time in space, at almost 438 days, but Rubio's stay surpassed U.S. astronaut Mark Vande Hei's previous recordof 355 days, set in 2022. 

Despite continuous references to Wilmore and Williams as "stuck"and "stranded," even being dubbed as such by SpaceX's billionaire founder Elon Musk, the Dragon capsule intended to bring them and their crewmates home had been docked at the space station since September 2024. That means in the event of an emergency at the laboratory, orbiting 250 miles above Earth, the astronauts could have evacuated and returned home. 

Still, rampant misinformation and politics seemed to hijack that narrative. Musk, who has since become President Donald Trump's most visible kitchen cabinet adviser, claimed in late Januarythat SpaceX wanted to move up the astronauts’ return but that former President Joe Biden's administration was to blame for the delay. Trump has echoed those remarks.

Wilmore and Williams have achieved an unexpectedly high level of name recognition — known to most as simply Butch and Suni — but they are not traveling alone on this journey. With them will be crewmates Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov.

Rather than deserted castaways, Wilmore and Williams remained at the lab to ensure it was fully staffed before Crew-10 arrived to relieve them. Those replacements — Anne McClain, Nichole Ayers, Takuya Onishi, and Kirill Peskov — successfully reached the space stationon Sunday, March 16.
