Sunitha Williams, a Nasa astronaut on the International Space Station, is healthy and not suffering from any medical problems, Nasa's top medical officer said Thursday. The unusual pronouncement was prompted by news articles suggesting that Williams was experiencing health problems during an unplanned extended stay in orbit. That in turn set off widespread rumors on social media.
