Post navigation 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. A giant geological structure over 140 kilometres in diameter was discovered in remote northwest Australia, which is thought to be the result of an asteroid impact that could have happened over 300 million years ago. The crater could be the largest of its kind discovered, possibly matching the size of the famous Vredefort crater in South Africa, the largest known impact crater on Earth. Scientists are now researching further to determine when the impact occurred and its exact size.
