Video: Atlas 5 rocket launches space station cargo mission

The 100th rocket in America’s Evolved Expendable Launch Vehicle program, the current fleet of boosters used by the nation to get its critical assets into space, was rolled to the pad Friday morning for a vital mission on Saturday.

The threat from Hurricane Nicole churning toward a tracking station in Bermuda will keep Orbital ATK’s Antares rocket from launching on a space station cargo run until at least Sunday, officials said Tuesday.

NASA civil servants and the agency’s contractor work force are bracing for high winds and rain from Hurricane Dorian, securing rocket stages, spacecraft assembly areas and even hauling a 6.7-million-pound mobile launch tower, designed for the huge rocket being built for the Artemis moon program, back to the cavernous Vehicle Assembly Building for safekeeping.
