A SpaceX Crew Dragon capsule carrying four astronauts from NASA’s Crew-12 mission splashed down in the Pacific Ocean west of Los Angeles on Thursday, concluding a 237-day stay aboard the International Space Station (ISS). The spacecraft, named Freedom, executed a controlled reentry and landed at 11:34 a.m. ET, approximately 50 miles off the California coast, where a recovery team retrieved the crew and capsule.
The returning astronauts included NASA commander Jessica Meir, pilot Jack Hathaway, European Space Agency (ESA) astronaut Sophie Adenot, and Russian cosmonaut Andrey Fedyaev. Their mission, which began with a launch from Cape Canaveral, Florida, on February 13, involved dozens of scientific experiments, including studies on stem cells, bone loss in microgravity, and crystal growth in space. Meir also conducted four spacewalks totaling 27 hours, while Adenot performed three spacewalks to maintain and upgrade the ISS.
Reentry and Landing
The crew’s return began with the undocking of the Crew Dragon capsule from the ISS at 8:05 a.m. ET on Wednesday, followed by a 27-hour transit toward Earth. At 10:46 a.m. ET Thursday, the spacecraft fired its thrusters for nine minutes to slow its orbit, initiating reentry. The capsule then endured extreme temperatures of up to 3,500°F as it plummeted through the atmosphere at nearly 5 miles per second, decelerating rapidly due to atmospheric friction. Four main parachutes deployed at an altitude of roughly 120 mph, guiding the capsule to a gentle 15-mph splashdown in the Pacific.
A SpaceX recovery ship, Shannon, arrived at the landing site to stabilize the capsule and assist the crew. Flight surgeons conducted initial medical checks as the astronauts began readjusting to gravity after eight months in microgravity. The crew was then flown by helicopter to shore before being transported to NASA’s Johnson Space Center in Houston for physical therapy and rehabilitation.
Mission Highlights and Scientific Contributions
During their time aboard the ISS, the Crew-12 astronauts contributed to hundreds of research projects, many of which are critical for future long-duration missions to the Moon and Mars. Key experiments included:
- Stem cell research, which may advance medical treatments on Earth and in space.
- Bone density studies, examining how microgravity affects skeletal health to inform countermeasures for astronauts.
- Crystal growth experiments, which could improve manufacturing processes in space.
The mission marked SpaceX’s 20th crewed orbital flight, continuing a partnership with NASA under the Commercial Crew Program. The agency emphasized that the data collected during Crew-12’s stay will support future Artemis missions and deep-space exploration.
Crew Reflections and Future Plans
In remarks prior to departure, Commander Jessica Meir expressed her anticipation for reuniting with her 3½-year-old daughter and experiencing Earth’s natural elements, stating, “I'm so looking forward to seeing nature again, feeling the breeze on my face, the wind rustling through the leaves.”
The successful return of Crew-12 ensures the continuous rotation of astronauts aboard the ISS, maintaining a steady presence of international crews for ongoing research and station maintenance. NASA and its international partners, including Roscosmos and ESA, will now prepare for the next crewed mission, Crew-13, which is scheduled to launch later this year.
