Astronauts on the International Space Station (ISS) got an eyeful of Hurricane Irene's increasing might today (Aug. 25) as their space capsule streaked over the monstrous Category 3 storm, which is barreling toward U.S. shores. Ahead of the flyover, ISS video cameras revealed placid views of wispy white clouds scattered over the blue of the ocean. Then a huge mass of white appeared on the horizon: Hurricane Irene, a powerful debut storm for the 2011 Atlantic hurricane season. Even from 220 miles (350 kilometers) above the Earth, the storm's muscle was on full display.
