SpaceX is launching its fourth mission in 8 days, this time to carry a payload consisting of a set of 60 more of its internet-beaming satellites – a part of Starlink, its bid to create an expansive global satellite-internet network. The mission tonight has a one-hour launch window beginning at 11:31 p.m. from Cape Canaveral Air Force Station’s Launch Complex 40, and will be streamed live. This fourth flight is part of a record-breaking cadence of space launches by the company.
