太空機組人員緊急醫療撤離後提前濺落地球！

Four astronauts returned to Earth earlier than planned after a medical emergency on the International Space Station. The crew, known as Crew-11, included NASA astronauts Mike Fincke and Zena Cardman, Japanese astronaut Kimiya Yui, and Russian cosmonaut Oleg Platonov. They were supposed to stay on the ISS for six and a half months, but their mission was cut short by a month because one of them became seriously ill. The astronauts landed safely in the ocean off the coast of California. Mike Fincke was the first to exit the spacecraft, smiling and looking a bit unsteady before lying down on a stretcher, which is a normal procedure after being in space. The rest of the crew followed, waving and smiling for the cameras. Zena Cardman said, 'It's so good to be home! '

This is the first time in the history of the International Space Station, which has been in orbit since 1998, that astronauts have been evacuated early due to a health issue. After landing, the crew will have medical checks before flying home. NASA administrator Jared Isaacman said the sick astronaut is 'fine right now' and in 'good spirits. ' NASA usually does not share the names or details of astronauts' health problems, so it is unlikely the public will know more about what happened. Control of the ISS has now been handed over to Russian cosmonaut Sergey Kud-Sverchkov and two other crew members. The remaining crew will continue their work until more astronauts arrive in February.

The International Space Station orbits Earth at an altitude of 250 miles and travels at a speed of 17,500 miles per hour, circling the planet 16 times a day. It is managed by five space agencies and is used for scientific research about space and how living in microgravity affects humans, animals, and plants. The ISS has some medical equipment, and astronauts are trained to handle minor health issues, but there is no doctor on board. This evacuation was a serious test of NASA's emergency procedures, and it seems they handled it well. However, some experts wonder how NASA would respond if there was a more serious medical emergency in space. The ISS now has only three astronauts on board, which is fewer than usual, but they are determined to keep working and complete their scientific and maintenance tasks. The space station has been continuously inhabited for 26 years, and only two other space missions in history have ended early because of health problems. As more people travel to space in the future, including for tourism or missions to the Moon or Mars, experts say it will be important to have doctors on board.
