— Blinded by the light: How bad are satellite megaconstellations for astronomy? If all goes to plan on Sunday, the Falcon 9's first stage will return to Earth about 8.5 minutes after liftoff, touching down in the Atlantic Ocean on the SpaceX drone ship "A Shortfall of Gravitas." It will be the debut flight for this particular booster, according to a SpaceX mission description. That's quite rare, as the company is known for its rocket reuse; its most-flown Falcon 9 has 29 flights under its belt. The Falcon 9's upper stage, meanwhile, will continue carrying the 24 Project Kuiper satellites to LEO. They'll be deployed over a 7.5-minute span beginning about 56 minutes after liftoff, if all goes to plan.
