Four more satellites for SES Networks’ O3b broadband fleet launched Thursday aboard a Soyuz rocket. Liftoff of the Soyuz launcher from the Guiana Space Center in South America occurred at 1703 GMT (1:03 p.m. EDT).

After an 11-day delay, SpaceX planned to deploy 60 more Starlink broadband satellites with a Falcon 9 rocket launch scheduled for 10:22 a.m. EDT (1422 GMT) Monday from NASA’s Kennedy Space Center in Florida. But SpaceX scrubbed the launch less than a minute before liftoff due to bad weather.

SpaceX and OneWeb — space industry rivals and owners of two of the largest fleets of commercial satellites — are set to add more spacecraft to their internet networks Wednesday with launches from Cape Canaveral and Russia.
