NASA is considering bringing astronauts home early from the International Space Station after a medical issue prompted the cancellation of a scheduled spacewalk, according to agency officials and media reports published this week. The situation involves a crew member currently aboard the orbiting laboratory, though NASA said there is no immediate danger to the astronaut or the station.

The U.S. space agency confirmed Tuesday that a planned spacewalk was called off out of an abundance of caution after medical concerns were identified during routine health monitoring. Officials said the affected astronaut is stable and continues to work with flight surgeons while remaining aboard the station.

According to NASA, crew health protocols require continuous assessment, and mission timelines can be adjusted if medical evaluations indicate elevated risk. The agency emphasized that astronaut safety remains the top priority and that contingency plans are standard practice for long-duration missions.

The astronauts are currently living and working aboard the International Space Station, a joint project involving the United States, Russia, Europe, Japan, and Canada. The station orbits Earth approximately every 90 minutes and serves as a platform for scientific research, technology testing, and human spaceflight operations.

NASA officials said no final decision has been made regarding an early return, and all options remain under review. Any change to the mission schedule would depend on continued medical assessments and coordination with international partners.

The agency added that mission control teams in Houston are closely monitoring the situation and maintaining regular communication with the crew. Normal station operations are continuing while medical evaluations proceed.

NASA did not disclose specific medical details, citing astronaut privacy, and noted that updates would be provided if the mission status changes.
