Live coverage: Vega rocket launches with LISA Pathfinder

A European supply freighter is set to undock from the International Space Station on Saturday, heading for a destructive dive into Earth’s atmosphere about 30 hours later after a power system failure forced the cancellation of an experiment to observe the dynamics of the re-entry of a large spacecraft.

The sharp-eyed science camera on Europe’s Rosetta comet orbiter caught a view of the probe’s fuzzy shadow when controllers guided the spacecraft just a few miles over its subject’s nucleus last month.

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.
