Indian-American astronaut Sunita Williams, who set a world record for the longest uninterrupted space flight by a woman, will return home this week after NASA cleared space shuttle Atlantis' thermal protection system for re-entry into the earth's atmosphere. According to NASA, Atlantis is set to leave the International Space Station (ISS) on Tuesday and will land at Cape Canaveral, Florida, on Thursday.
