Video: When Juno launched to begin 5-year trek to Jupiter

Critical operations were completed this morning by United Launch Alliance at Cape Canaveral to prepare two rockets for upcoming flights into space.

SpaceX successfully launched 60 more Starlink internet satellites Monday night from Cape Canaveral, but lost the Falcon 9 rocket’s reusable first stage booster during a landing attempt on a drone ship parked in the Atlantic Ocean.

Ground crews finished the initial build-up of the last “single stick” medium-lift variant of United Launch Alliance’s Delta 4 rocket on its launch pad at Cape Canaveral last week in preparation for liftoff with a GPS navigation satellite July 25.
