Video: Atlas 5 rocket launches space station cargo mission

Rocket Lab counted down to the second test flight of its commercial Electron satellite launcher Monday, U.S. time, but a dramatic computer-commanded abort triggered moments after its engines ignited kept the light-class booster on its New Zealand launch pad for at least two more days.

This is the ascent timeline to be followed by the Atlas 5 rocket’s ascent into orbit from Vandenberg Air Force Base in California with the commercial WorldView 4 Earth-imaging satellite for DigitalGlobe. Launch is scheduled for Friday at 11:30 a.m. local time (2:30 p.m. EDT; 1830 GMT).

A Japanese H-2A rocket launched at 5:58 p.m. EDT (2158 GMT) Sunday from the Tanegashima Space Center with the Emirates Mars Mission’s Hope orbiter, the UAE’s first probe to Mars.
