Live coverage: Orion lands in Pacific

Europe’s Rosetta spacecraft closed out a historic 4.9-billion-mile journey Friday with a slow-speed crash into the nucleus of comet 67P/Churyumov-Gerasimenko, the tiny world it has studied for the last two years, capturing some of the mission’s best science data to help unravel the inner workings of the comet. Confirmation of the crash landing arrived on Earth at 1119 GMT (7:19 a.m. EDT).

After tropical weather passes through Florida to start the week, meteorologists say there is a 40 percent chance of acceptable conditions for the United Launch Alliance Delta 4-Heavy rocket to fly Thursday from Cape Canaveral with a reconnaissance satellite payload for the U.S. government.

SpaceX has launched its third Falcon 9 of the year. The rocket is carrying a pair of communications payloads for Eutelsat and Asia Broadcast Satellite.
