Japan astronaut sorry for 9cm growth error
A Japanese astronaut has apologised for wrongly stating he has grown 9cm (3.5in) since arriving at the International Space Station (ISS) just over three weeks ago. Norishige Kanai said in fact he grew by 2cm, blaming "a measurement mistake". "I'm very sorry for tweeting out such fake news," he tweeted in Japanese. His original incorrect claim sparked global fascination among social media users. Astronauts grow an average of between 2-5cm in space.
