On January 8th, Japanese astronaut Norishige Kanai caused some concern when he tweeted that he'd grown about 9 cm (around 3 and a half inches) in his three weeks about the International Space Station. Well, it turns it that's not actually the case. Kanai, who tweeted an apology last night, said that he re-measured himself after the media flurry surrounding his announcement, and he's only grown about 2 cm.
