SpaceX launches 60 Starlink satellites on record-setting used rocket, nails landing
CAPE CANAVERAL, Fla. —
SpaceX launched 60 more Starlink internet satellites to orbit this morning (Feb. 4) on a mission that notched a booster-reusability milestone for the company.
A two-stage
Falcon 9 rocket topped with the 60 broadband spacecraft lifted off from Space Launch Complex 40 here at Cape Canaveral Space Force Station today at 1:19 a.m. EST (0619 GMT). Approximately nine minutes later, the rocket's first stage returned to Earth, landing smoothly on one of SpaceX's drone ships in the Atlantic Ocean.
The massive ship, "Of Course I Still Love You," is one of two SpaceX vessels that catch falling boosters and return them to port.
It was the fifth launch for this Falcon 9 first stage, which last flew just 27 days ago — the quickest turnaround between missions for any SpaceX booster. Today's launch was also the first of two nearly back-to-back Starlink liftoffs; another 60 satellites are scheduled to take flight early Friday morning (Feb. 5) on a different Falcon 9.
Today's launch, dubbed Starlink 18, leapfrogged that coming flight, known as Starlink 17. Starlink 17 was supposed to get off the ground on Monday (Feb. 1) but was delayed due to poor weather in the recovery zone and the need for extra pre-flight checks......
Starlink 17, the other part of the doubleheader, was originally set to blast off Monday (Feb. 1). It was initially pushed 24 hours to allow for improved weather conditions at the recovery zone, then delayed several more times, causing it to switch places with Starlink 18. SpaceX relies heavily on its fleet of reused rockets, so the company wants to make sure that its recovery efforts are successful.
Starlink 17 will mark just the second time that one of the company’s Falcon 9 first stages has flown eight times. The booster, known by the designation B1049, launched a Telstar communications satellite in September 2018, lofted an Iridium NEXT satellite in January 2019, and then flew five different Starlink missions.
GO Ms. Tree and GO Ms. Chief will likely scoop both fairing pieces — SpaceX fairings come back to Earth in two halves — out of the ocean for future reuse. Both fairing halves on this mission have been used before.
