NASA astronaut Nick Hague and Roscosmos cosmonaut Alexey Ovchinin were aboard the spacecraft when it launched at 4:40 a.m. EDT on a mission to the station. The duo blasted off from Kazakhstan's Baikonur Cosmodrome aboard the Russian Soyuz MS-10 spacecraft.
Moments after launch, the two were forced to eject from the spacecraft after they encountered trouble with a booster on the rocket.
