A Russian Soyuz spacecraft will launch an American astronaut and two cosmonauts to the International Space Station early Friday (April 9) — and you can watch it live online.

The Soyuz capsule carrying NASA astronaut Mark Vande Hei, Oleg Novitskiy and Pyotr Dubrov is scheduled to launch atop a Soyuz rocket from Baikonur Cosmodrome in Kazakhstan at 3:42 a.m. EDT (0742 GMT or 12:42 p.m. local time) on Friday for a quick, three-hour ride to the International Space Station.
