Follow the key events of the Falcon 9 rocket’s ascent to orbit 60 satellites for SpaceX’s Starlink broadband network.

A Northrop Grumman Antares rocket, upgraded to carry heavier payloads into orbit, lifted off Saturday from a launch pad on Virginia’s Eastern Shore with a Cygnus supply ship in pursuit of the International Space Station with fresh food, a collection of biological and technology demonstration experiments, a zero-g baking oven, and repair gear for an aging $2 billion particle physics experiment.

Officials have delayed the launch of a United Launch Alliance Atlas 5 rocket with the European-built Solar Orbiter spacecraft from Cape Canaveral by two days to Feb. 7, a ripple effect from time spent fixing a minor issue last week during a launch vehicle countdown dress rehearsal.
