Four new astronauts arrived at the International Space Station, after last month a medical emergency evacuation was carried out for one of the crew members and three of his colleagues left with him. NASA did not specify which crew member fell ill and caused the first emergency evacuation in 65 years of manned spaceflight. The space agency said that the pre-flight medical examinations for the new crew were not changed. The four new astronauts are Jessica Meir and Jack Hathaway from NASA, Sophie Adenot from France and Andrei Fedyaev from Russia.
