Two NASA Astronauts Safely Return to Earth After Nine Months Stranded in Space
Two NASA astronauts, Sunita Williams and Barry Wilmore, have finally returned to Earth after being stuck in space for nine months. They left the International Space Station (ISS) early Tuesday morning and landed safely off the coast of Florida after a 17-hour journey. Originally, they were supposed to return on Boeing’s Starliner spacecraft, but it was deemed unsafe, forcing them to stay in space much longer than planned.
Who Are the Astronauts?
Sunita “Suni” Williams, 59, and Barry “Butch” Wilmore, 62, are both experienced NASA astronauts. Williams, the current commander of the ISS, is a retired U.S. Navy officer who joined NASA in 1998. She has spent 322 days in space and completed nine spacewalks, holding the record for the most spacewalks by a female astronaut until 2017. Wilmore, a seasoned astronaut, first flew to space in 2009 on the Space Shuttle Atlantis. Before this mission, he had spent 178 days in space, working as a flight engineer and commander on previous ISS missions. He has conducted research on plant growth in space, the effects of microgravity on the human body, and environmental changes on Earth.
During the Boeing mission, Wilmore served as the commander, and Williams was the pilot.
How Did They Return to Earth?
The astronauts’ journey home began late Monday night. The SpaceX Crew Dragon capsule, which had been docked at the ISS since September 2024, undocked at 1:05 a.m. ET on Tuesday. It splashed down in the Atlantic Ocean just before 6 p.m. ET the same day. NASA livestreamed the entire process.
The Crew Dragon capsule had originally brought NASA astronaut Nick Hague and Russian astronaut Aleksandr Gorbunov to the ISS, with two empty seats reserved for Williams and Wilmore’s return. However, the four astronauts couldn’t return together until a replacement crew arrived. That replacement, Crew-10, docked at the ISS on Sunday and included NASA astronauts Anne McClain and Nichole Ayers, Japanese astronaut Takuya Onishi, and Russian astronaut Kirill Peskov.
Why Were They Stranded?
Williams and Wilmore got stuck in space due to technical issues with Boeing’s Starliner spacecraft, which was supposed to bring them home. They had traveled to the ISS on Starliner’s first crewed test flight, part of NASA’s Commercial Crew Program, which aims to develop private spacecraft for transporting astronauts to and from the ISS.
During the 25-hour flight to the ISS, Starliner experienced helium leaks and thruster malfunctions, which are critical for steering and reentry. When the spacecraft arrived on June 6, four more thrusters failed, delaying docking. Although engineers fixed four of the five failed thrusters, NASA decided the spacecraft was too risky for human travel and sent it back empty, leaving Williams and Wilmore stranded.
In August 2024, NASA decided to bring them back on a SpaceX Crew Dragon capsule. However, bringing them home earlier would have left only one U.S. astronaut on the ISS, limiting research and emergency response capabilities. With the arrival of Crew-10, Williams and Wilmore were finally able to return.
How Long Were They Stranded?
Williams and Wilmore had been in space since June 5, 2024, meaning they spent over nine months in orbit. Originally, they were scheduled to stay for just eight days. The standard ISS mission lasts about six months.
How Did They Survive for So Long?
Despite the unexpected extension, Williams and Wilmore remained in good health. They even conducted a spacewalk together in January. Life on the ISS follows a structured routine of exercise, work, and leisure. They exercised regularly on a treadmill and resistance machine to maintain bone and muscle strength.
Throughout their stay, several space agencies and private companies resupplied the ISS with food, water, and oxygen. Over Christmas, the astronauts enjoyed a festive dinner that included smoked oysters, crab, duck foie gras, cranberry sauce, Atlantic lobster, and smoked salmon. They also stayed in touch with their families through email and phone calls.
In an interview in November, Williams said, “We’re feeling good, working out, eating right. We have a lot of fun up here too. People who are worried about us, really, don’t worry about us… We’re a happy crew up here.”
Have Astronauts Been Stranded Before?
Williams and Wilmore aren’t the first astronauts to face an extended stay in space. In 2022-2023, U.S. astronaut Frank Rubio spent 371 days on the ISS due to issues with the Soyuz spacecraft that brought him there. He eventually returned on a different Soyuz capsule. In 1991, Soviet astronaut Sergei Krikalev was stranded on the Mir space station for 311 days due to the dissolution of the Soviet Union. Political and funding issues delayed his return, and he landed in a newly independent Russia in 1992.
Despite the challenges, Williams and Wilmore’s safe return marks another successful chapter in space exploration.
