Live coverage: Vega rocket launches with LISA Pathfinder

An Ariane 5 rocket will fire into the sky from French Guiana just after sunset Tuesday and deliver two payloads to orbit for Intelsat, one of the world’s largest commercial satellite operators, and Broadcasting Satellite System Corp. of Japan.

A pair of Air Force surveillance satellites headed to geosynchronous orbit today to reconnoiter the high ground, departing Cape Canaveral aboard a United Launch Alliance Delta 4 rocket at 12:52 a.m. EDT (0452 GMT). It is the 375th Delta rocket flight since 1960.

Arianespace has announced OneWeb, the broadband Internet provider seeking to deploy more than 600 satellites into low Earth orbit, as the launch customer for the inaugural flight of the new Ariane 6 rocket in 2020.
