Live coverage: Atlas 5 countdown and launch journal

United Launch Alliance crews at Cape Canaveral are finishing final preparations for an Atlas 5 rocket launch Saturday evening to dispatch three U.S. military satellites directly to an orbital perch more than 20,000 miles over the equator.

A Russian Soyuz booster arrived at its launch pad on the Kazakh steppe Sunday, the last stop before liftoff Wednesday with a three-person crew bound for the International Space Station.

After assessing any damage to the spaceport caused by Hurricane Dorian as it narrowly missed Florida’s east coast, NASA says the Kennedy Space Center will reopen for normal operations Friday. Teams rolled the Space Launch System’s mobile launch platform from pad 39B back into the cavernous Vehicle Assembly Building last week for safekeeping during the storm.
