4 astronauts arrive at International Space Station to replace Nasa’s evacuated crew

The International Space Station returned to full strength with Saturday’s arrival of four new astronauts to replace colleagues who bailed early because of health concerns.SpaceX delivered the US, French and Russian astronauts a day after launching them from Cape Canaveral.Last month’s medical evacuation was NASA’s first in 65 years of human space flight.One of four astronauts launched by SpaceX last summer suffered what officials described as a serious health issue, prompting their hasty return.That left only three crew members to keep the place running – one American and two Russians – prompting NASA to pause spacewalks and trim research.Moving in for eight to nine months are NASA’s Jessica Meir and Jack Hathaway, France’s Sophie Adenot and Russia’s Andrei Fedyaev.France’s Sophie Adenot, Russia’s Andrei Fedyaev and Americans Jessica Meir and Jack Hathaway greet colleagues as they enter the International Space Station on Saturday.
