Just days after the announcement that last year was the warmest in history for the continental United States, NASA and NOAA found global temperatures are rising too.
Our goal is nothing less than the human breakout into space, the expansion of human civilization and the life of Earth beyond our world, to all worlds and all places in between.
Guy Laliberte, a Canadian former acrobat and fire-eater who had founded Cirque du Soleil in the 1980s, was announced as the next space tourist to visit the International Space Station aboard a Russian Soyuz spacecraft.
