Live coverage: SpaceX successfully performs Crew Dragon abort test

An unmanned cargo freighter carrying nearly four tons of supplies and science, launched and operated commercially for NASA, blasted off from Cape Canaveral on Tuesday atop an Atlas 5 rocket bound for the International Space Station.

A solid-fueled Long March 11 rocket fired out of a container aboard a barge in the Yellow Sea on Wednesday with seven satellites heading into orbit on China’s first space launch from an ocean vessel.

NASA officials said Tuesday the weekend test-firing of the Space Launch System moon rocket’s core stage was cut short by an out-of-limits parameter in a hydraulic system for gimbaling, or vectoring, one of its engines. NASA Administrator Jim Bridenstine told Spaceflight Now engineers are “feeling pretty good” about the data gathered during the shortened test-firing, and managers may decide to ship the SLS core stage to the Kennedy Space Center for launch preparations without re-attempting the planned eight-minute hot fire.
