Live coverage: Falcon 9 launches ocean study satellite, barge landing fails

The liftoff of a Rocket Lab Electron booster from New Zealand with five U.S.- and German-built nanosatellites was grounded Tuesday, U.S. time, after engineers identified a problem with a motor controller on the two-stage launcher.

SpaceX has moved up its next launch to Wednesday, one day earlier than previously planned. A Falcon 9 rocket will take off with the next 60 satellites for SpaceX’s Starlink broadband Internet network at 3:37 p.m. EDT (1937 GMT) Wednesday from pad 39A at NASA’s Kennedy Space Center in Florida. There’s a 90 percent chance of favorable weather for launch Wednesday.

Ground crews at Vandenberg Air Force Base in California raised a United Launch Alliance Atlas 5 rocket on its launch pad earlier this month in preparation for liftoff May 5 with NASA’s InSight lander heading to Mars.
