Live coverage: Vega rocket launches with LISA Pathfinder

Launch managers in French Guiana have delayed liftoff of a European gravitational probe pathfinder at least one day to study out-of-bounds thermal readings from the upper stage of its Vega rocket booster, officials said Tuesday.

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.

Two Galileo navigation satellites arrived at the Guiana Space Center in South America on Thursday after a trans-Atlantic flight from Paris, as European officials plan the resumption of Galileo launches after a rocket mishap deposited two spacecraft in the wrong orbit last year.
