The SpaceX Falcon 9 rocket launch was scrubbed 15 seconds before takeoff.
The reason they gave was due to probability of landing failure.
They will attempt a third launch tomorrow, Thursday, at 6:40 a.m.
A SpaceX rocket launch is scheduled to take place this Wednesday, April 26 at Vandenberg Space Force Base.
The Falcon 9 rocket is set to take off at 6:40 a.m.
The rocket will be carrying 46 Starlink satellites into low-Earth orbit. Starlink is SpaceX's high-speed broadband satellite internet service designed to reach remote communities.
Following stage separation, about eight minutes after liftoff, SpaceX plans to land the rocket's first stage booster on the Of Course I Still Love You droneship stationed in the Pacific Ocean. The booster being used in this launch was used in a dozen previous missions.
If the launch is scrubbed for any reason, there is a backup launch opportunity at the same time on Thursday, April 27. This launch was originally scheduled to take place on Tuesday, but SpaceX announced its delay just before 6 a.m.
A live webcast of the launch is scheduled to begin about five minutes prior to liftoff.
