COURTESY SPACEX                                 Astronauts Doug Hurley and Bob Behnken prepare to return to earth on a SpaceX capsule today. It will mark the first splashdown in 45 years for NASA astronauts and the first return in the gulf. Unlike Florida's Atlantic coast, already feeling the effects of Tropical Storm Isaias, the waves and wind were calm near Pensacola in the Florida Panhandle.
