Watch the Falcon 9 light its engines for a static test fire (members only)

The launch of a European Ariane 5 rocket was aborted moments after its main engine ignited Tuesday. The dramatic last-second hold was the first time an Ariane rocket launch was aborted after engine start since March 2011. Arianespace has not set a new target launch date for the mission, which will loft two U.S.-built communications satellites for Intelsat and B-SAT.

Northrop Grumman’s Pegasus XL rocket will take about 11 minutes to place NASA’s Ionospheric Connection Explorer, or ICON, satellite into a roughly 357-mile-high (575-kilometer) orbit after an airborne launch off Florida’s east coast.

Five satellites rode a Soyuz booster into orbit Monday from French Guiana, and these spectacular photos from Europe’s tropical spaceport show the legendary rocket’s fiery departure from the edge of the lush Amazon jungle.
