Live coverage: Vega rocket launches with LISA Pathfinder

An Ariane 5 rocket and four Galileo navigation satellites launched from French Guiana at 1125 GMT (7:25 a.m. EDT), beginning a four-hour climb into orbit more than 14,000 miles above Earth.

The first in a planned multi-decade series of European land imaging satellites is fastened on top of a solid-fueled Vega launcher at a French Guiana space base for liftoff Monday, kicking off a mission to track everything from global crop growth to urban sprawl.

SpaceX’s first launch since August took off Saturday from Vandenberg Air Force Base in California. A Falcon 9 rocket deployed the first 10 next-generation Iridium communications satellites, part of a $3 billion upgrade to the company’s space network. Liftoff occurred at 9:54 a.m. PST (12:54 p.m. EST; 1754 GMT), and the Falcon 9’s first stage landed on a barge in the Pacific a few minutes later.
