New York: The rainbow hues of lakes that dot the Himalayas helped NASA astronaut Scott Kelly keep his wits during his 340-day mission aboard the International Space Station which aimed at studying the effects of weightlessness in humans, the media reported. “The earth is a beautiful planet,” Kelly said in Houston, as he described the striking colours of the waters around the Bahamas and the beautiful lakes that dot the northern Himalayas.
