Photos: America’s 100th EELV blasts off

United Launch Alliance’s first full-scale Vulcan booster with two Blue Origin BE-4 engines arrived at Cape Canaveral Space Force Station on Saturday, the first time in more than a decade that a core stage from a new family of orbital-class rockets has rolled into the Florida launch facility.

A Chinese Long March 7A rocket failed to place a secret payload into orbit Monday, casting doubt on planned flights by the country’s other launchers that use similar engines.

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.
