Live coverage: Vega rocket launches with LISA Pathfinder

European Space Agency flight controllers are plotting to send the Rosetta spacecraft on a controlled descent to the surface of comet 67P/Churyumov-Gerasimenko next year to join the Philae landing probe, which made a bouncy touchdown on the comet’s craggy nucleus one year ago this week.

Northrop Grumman’s launch team aborted an Antares rocket launch from Virginia’s Eastern Shore minutes before liftoff Sunday evening. The rocket is set to loft a Cygnus cargo freighter toward the International Space Station with nearly four tons of supplies and experiments.

Two U.S.-built commercial communications satellites moved to their last stop on Earth on Tuesday, when an Ariane 5 rocket rolled out to a launch pad at the edge of the Amazon jungle on the eve of liftoff.
