Watch a replay of the launch of a Japanese navigation satellite

Days after SpaceX opened preorders for Starlink internet service, two more Falcon 9 rockets are set to launch from Florida’s Space Coast as soon as Sunday night and Wednesday morning — weather permitting — to help push the network closer to commercial operations.

The first 34 satellites manufactured on a new commercial spacecraft assembly line just outside the gates of the Kennedy Space Center in Florida are scheduled for liftoff on a Soyuz rocket Thursday halfway around the world in Kazakhstan, kicking off a sequence of up to 20 launches from three countries to deploy nearly 650 satellites for OneWeb’s global Internet network.

Ten new satellites joined Iridium’s global voice and data relay constellation Sunday after a successful launch, and landing, of a SpaceX Falcon 9 rocket from Vandenberg Air Force Base in California. Liftoff occurred at 1:25 p.m. PDT (4:25 p.m. EDT; 2025 GMT).
