The four-person crew from NASA‘s SpaceX Crew-11 mission to the International Space Station are set to splash down off the coast of San Diego County early Thursday.

The splashdown is scheduled for 12:41 a.m., according to NASA.

The SpaceX Dragon crew spacecraft undocked from the International Space Station’s Harmony module at 2:20 p.m. Pacific Standard Time to begin the trip back to Earth, according to NASA.

NASA announced last Thursday the crew would be leaving the International Space Station earlier than originally planned due to a medical concern. The crew member was only described as stable.

Due to medical privacy, “it is not appropriate for NASA to share more details about the crew member,” the agency announced.

The crew consists of two NASA astronauts, Zena Cardman and Mike Fincke, Japan Aerospace Exploration Agency astronaut Kimiya Yui, and Russian cosmonaut Oleg Platonov.

Live coverage of return and related activities will stream on NASA+, Amazon Prime and the agency’s YouTube channel beginning at 11:15 p.m. Wednesday.
