SpaceX will attempt to launch the tenth set of around sixty satellites for their Starlink broadband network, which they will use to provide internet access to everywhere in the world - including remote areas currently without internet and for places such as on board aircraft and vessels at sea. Also sharing the ride to space are two Earth-observation satellites for BlackSky Global . The first stage booster which will send the payload and second stage to space will be landing back on Earth approximately 8 minutes after launching, which will be streamed live as well as the launch.
The launch is currently scheduled for Friday, August 7th at 05:12 UTC (06:12BST).
The launch can be viewed live 15 to 20 minutes before life-off here: SpaceX YouTube Channel
