Live coverage: Vega rocket launches with LISA Pathfinder

SpaceX’s next Falcon 9 rocket launch, using a previously-flown first stage booster, took a step closer to liftoff Thursday with a countdown rehearsal culminating in ignition of the launcher’s nine Merlin main engines in a hold-down firing at pad 39A at NASA’s Kennedy Space Center in Florida.

SpaceX launched a Falcon 9 rocket from California’s Central Coast at 10:42:18 a.m. PST (1:42:18 p.m. EST; 1842:18 GMT) Sunday with the Jason 3 oceanography satellite. A secondary objective of the mission to recover the first stage on a barge in the Pacific Ocean failed.

A Vega rocket lifted off from a tropical launch pad in French Guiana at 1351 GMT (8:51 a.m. EST) Monday with Gokturk 1, a sharp-eyed reconnaissance satellite built in France and owned by the Turkish armed forces.
