American astronauts return to space today

Today's Video of the Day from NASA describes how to virtually participate in "Launch America," as the first human spaceflight is launched from the United States since 2011. Today, American astronauts will once again travel to the International Space Station as part of the Commercial Crew Program. At 4:33 p.m., NASA astronauts Robert Behnken and Douglas Hurley will fly on SpaceX’s Crew Dragon spacecraft, lifting off on a Falcon 9 rocket from Florida's Kennedy Space Center. --- By Chrissy Sexton, Earth.com Staff Writer Video Credit: NASA
