The forecast of stormy weather prevented rollback of the mobile service gantry and the continuation of the countdown at Cape Canaveral on Wednesday for the United Launch Alliance Delta 4 rocket.

The liftoff of a European satellite to measure global wind fields has been delayed 24 hours to Wednesday in hopes of a better weather forecast at the Vega rocket’s launch base in French Guiana, officials announced Monday.

For the second consecutive day, SpaceX called off a Falcon 9 launch attempt at Cape Canaveral on Thursday evening, this time to complete a software update on the first 60 satellites for the company’s Starlink network to provide high-speed Internet service from orbit.
