The Starlink 17-9 mission added another 24 broadband satellites to its low Earth orbit constellation of more than 8,300. Liftoff from pad 4E at Vandenberg Space Force Base happened at 11:06 a.m. PDT (2:06 p.m. EDT / 1806 UTC).

A Soyuz rocket took off from a cosmodrome in Russia’s Far East and deployed 36 Florida-built OneWeb internet satellites into orbit Thursday. Another batch of OneWeb satellites will launch next month, continuing the build-out of a planned fleet of 648 spacecraft to provide global broadband services.
