Live coverage: Proton soars into space with Inmarsat satellite

An Ariane 5 rocket is counting down to a second launch attempt Saturday to carry two communications satellites into space for DISH Network and Indonesian banking customers, taking the heaviest payload ever launched into geostationary transfer orbit.

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).

Two new satellites for Eutelsat and Intelsat, two of the world’s largest telecom satellite operators, blasted off aboard an Ariane 5 rocket from South America’s Amazon jungle Thursday at 2034 GMT (4:34 p.m. EDT).
