Live coverage: Vega rocket launches with LISA Pathfinder

United Launch Alliance scrubbed the launch of a Delta 4-Heavy rocket Wednesday night less than 10 seconds before liftoff from Cape Canaveral, the second such abort suffered by this mission.. The launch of a classified National Reconnaissance Office spy satellite is expected to be delayed at least several more days as engineers assess the cause of Wednesday’s last-minute abort.

SpaceX launched a Falcon 9 rocket at 1:09 p.m. PDT (4:09 p.m. EDT) Wednesday from Vandenberg Space Force Base, California, on a mission hauling 51 more Starlink internet satellites into orbit.

Three days after high winds scrubbed a launch attempt Friday, Rocket Lab launched an Electron rocket with four satellites from New Zealand at 1212 GMT (8:12 a.m. EDT) Monday.
