NASA astronaut Reid Wiseman seems to be having a great time living in space, and he is using social media to share his experience with the world. Wiseman has taken some truly amazing pictures of Earth and the cosmos from the International Space Station since he boarded the orbiting outpost in May. The astronaut usually uses Twitter to beam back pictures from his life in space. "Enjoying the view on a Sunday afternoon," Wiseman wrote in a post on Twitter (@Astro_Reid) on Aug. 17. "Hard to believe this is real." The image attached to the post shows the astronaut gazing out the cupola, a seven-sided Earth-gazing window on the bottom of the space station.
