Live coverage: Ariane 5 blasts off with two Intelsat satellites

SpaceX aims to launch a Falcon 9 rocket Monday from Vandenberg Air Force Base in California with 10 new satellites for Iridium’s tracking and message relay constellation in low Earth orbit.

An Ariane 5 rocket took off from French Guiana Friday with the heaviest interplanetary science probe ever launched, kicking off a $1.7 billion European Space Agency mission on a decade-long quest to Jupiter’s icy moons in search of environments that could be habitable for life.

Forecasters will be watching clouds and rain showers during the countdown before Monday’s launch of a Falcon 9 rocket carrying Turkmenistan’s first communications satellite.
