Live coverage: Atlas 5 countdown and launch journal

The United Launch Alliance Atlas 5 rocket blasted off Thursday night with NASA’s Magnetospheric Multiscale satellite quartet in a successful flight from Cape Canaveral.

A billion-dollar U.S. military satellite rode a United Launch Alliance Atlas 5 rocket into orbit Friday night from Cape Canaveral, joining a network of space sentinels warning of threatening missile launches from North Korea, or any other place on the globe.

Orbital ATK plans to launch its next two commercial resupply missions to the International Space Station on Atlas 5 rockets, grabbing a launch slot in March after a next-generation U.S. weather satellite was delayed, industry officials said.
