SpaceX has launched yet another Starlink mission, adding 60 more Starlink satellites to its low-Earth orbit constellation. That’s good news for its efforts to blanket the globe in high-speed broadband, and today’s flight is even better news for its equally important ambition of developing more reusable rocket systems, since the first-stage booster that helped launch today’s Falcon 9 rocket made a record-breaking seventh trip. SpaceX broke its own reusability records of six flights for a reused first-stage rocket component, and it also recovered the booster with a controlled landing using its drone flight in the Atlantic Ocean, which means it could potentially break this record with yet another future flight for this same booster. Today’s launch took off from Cape Canaveral Air Force Station in Florida, lifting off at 9:13 PM EST (6:13 PM PST).
