Photos: Atlas 5 rocket aims for International Space Station

NASA wants to fly an astronaut on Russia’s next Soyuz mission to the International Space Station in April, a measure the agency says would ensure a continued U.S. presence on the research outpost in case of delays in the launch of SpaceX’s next Crew Dragon flight.

The United Launch Alliance Atlas 5 rocket lifted off from Cape Canaveral at 7:05 p.m. EDT (2305 GMT) today to send NASA’s OSIRIS-REx spacecraft on a seven-year, 4.4-billion-mile mission to rendezvous with Asteroid Bennu and bring a sample of the primordial object back to Earth. Follow the mission in our live journal.
