Live coverage: Delta 4 countdown and launch journal

United Launch Alliance’s next launch attempt for its Delta 4-Heavy rocket from Cape Canaveral with a top secret U.S. government spy satellite will be delayed to no earlier than early Tuesday.

Four satellites tucked inside the tip of a Soyuz rocket lifted off Thursday, heading for a 5,000-mile-high orbit to expand the reach of O3b’s broadband communications network. Liftoff from the European-run spaceport in French Guiana occurred at 1:37 p.m. EST (1837 GMT).

NASA astronauts Nick Hague and Drew Morgan completed a 6-hour, 32-minute spacewalk outside the International Space Station Wednesday to help connect a newly-arrived docking port to the orbiting research outpost.
