NASA Astronaut and Russian Cosmonauts Launch to ISS, Replacing Stuck Crew

NASA astronaut Loral O'Hara, along with Russian cosmonauts Oleg Kononenko and Nikolai Chub, are set to launch to the International Space Station (ISS) today. The crew will launch aboard a Soyuz spacecraft and make one of the fastest-ever trips to the ISS. They will serve as a relief crew for the current ISS crew, who have been in space for over a year due to a delayed return caused by a leak in their Soyuz spacecraft. This launch highlights the importance of having backup vehicles in case of emergencies.
