Nasa astronaut Scott Kelly decided to inject some monkey business into his time on the ISS by dressing up in a gorilla costume to torment his fellow ship mates. Kelly uploaded a video to his Twitter page on 23 February showing an unsuspecting astronaut, Britain's own Tim Peake, checking a large white box. A few seconds later a costumed Kelly comes out and proceeds to chase Peake around the space station.
Kelly's brother Mark also uploaded the video onto his Twitter page with the statement "Um, @StationCDRKelly, I thought you said you had things under control up there on @Space_Station? #ApeInSpace."
