Hurricane Gonzalo was taken from the International Space Station by European Space Agency astronaut Alexander Gerst.  The resort island chain of Bermuda braced October 17, 2014 for a hit from Hurricane Gonzalo, forecast to produce flooding, strong winds and a life-threatening storm surge. The capital Hamilton was eerily quiet as people retreated to the safety of their homes. Schools, businesses, grocery stores and government offices all closed early Thursday, and many people boarded up the windows of their homes and placed sandbags outside in preparation. As of early Friday, Gonzalo's winds were whirling at 125 miles (200 kilometers) per hour, with even stronger gusts, the US National Hurricane Center said. Gonzalo has already killed one person in the Caribbean and triggered a hurricane warning for the British overseas territory, which is home to around 60,000 people.

Earth seen from the International Space Station...epa04383191 A handout picture made available by NASA on 04 September 2014 shows a view of Earth taken by NASA astronaut Gregory Reid Wiseman of the US from the International Space Station (ISS) on space, 02 September 2014. The Expedition 40 crew has been busy on the ISS performing health checks and humanoid robot upgrades. A trio of orbital residents is packing up gear as they prepare to return home in less than two weeks. Commander Steve Swanson powered down and stowed Robonaut 2 after wrapping up its mobility upgrades this week. He installed new legs on the humanoid robot including external and internal gear as well as cables. This sets the stage for more upgrades in the fall before Robonaut takes its first steps as an assistant crew member. Robonaut was designed to enhance crew productivity and safety while also aiding people on Earth with physical disabilities.  EPA/NASA/REID WISEMAN  HANDOUT EDITORIAL USE ONLY
