SpaceX Launches Second Mission of 2021 with More Starlinks on 8x-Flown RocketBy Ben Evans, on January 20th, 2021

Photo Credit: Mike Killian / AmericaSpace.comAfter almost two years, SpaceX successfully passed the magical number of 1,000 Starlinks launched to orbit today, when the veteran B1051 core—the first Falcon 9 to record an eighth launch—roared aloft from historic Pad 39A at the Kennedy Space Center (KSC) in Florida, carrying a 60-strong “batch” of these flat-packed internet communications satellites. With today’s launch, 1,013 production-design Starlinks have been put into orbit since May 2019.
Following a 24-hour postponement from Monday, due to unfavorable weather in the recovery zone, B1051 again broke the shackles of Earth at 8:02 a.m. EST, creating a new record of less than 38 days between flights by the same orbital-class booster. A little more than an hour later, her payload triumphantly delivered to orbit, B1051 was bobbing serenely on the deck of the Autonomous Spaceport Drone Ship (ASDS), “Just Read the Instructions”, with high hopes that a ninth mission might not be too far off.
Early Wednesday, the veteran B1051 core became not only the inaugural Falcon 9 first stage to log an eighth mission, but also cemented its credentials for the shortest ever turnaround between two flights by the same booster.
And B1051’s credentials are nothing if not impressive. First launched in March 2019 to deliver an unpiloted Crew Dragon vehicle to the International Space Station (ISS) for the critical Demo-1 mission in support of the Commercial Crew Program, it went on to loft Canada’s three-spacecraft Radarsat Constellation Mission (RCM) the following June. Those first two missions saw B1051 fly both from Pad 39A at the Kennedy Space Center (KSC) in Florida and from Space Launch Complex (SLC)-4E at Vandenberg Air Force Base, Calif.
Following her stint on the West Coast, she returned east to fly no less than five missions between January and December 2020, delivering 237 Starlinks and SiriusXM’s SXM-7 high-powered radio broadcasting satellite aloft. In doing so, B1051 became the first Falcon 9 booster to launch both four times and five times in a single calendar year. She also earned an additional accolade on her April 2020 Starlink mission by eclipsing the United Launch Alliance (ULA) Atlas V as the most-flown operational U.S. launch vehicle.
All told, and counting this morning’s safe flight, B1051 has returned to Earth to complete seven Autonomous Spaceport Drone Ship (ASDS) landings and one touchdown on solid ground at Vandenberg’s Landing Zone (LZ)-4.
Having flown her most recent trek to deploy SXM-7 on 13 December,
today’s launch marked a little less than 38 days between two missions by the same Falcon 9 core. That achievement soundly surpasses her sister B1058, which logged 51 days—and broke a turnaround record for an orbital-class booster which extended right back to the pre-Challenger shuttle era—between two missions last summer. (...)
B1049 has lifted 298 Starlinks on five missions between May 2019 and last November, with B1051 sitting just one behind with a highly respectable 297. Add to that list Demo-1, the RCM triplets and a pair of imaging satellites for Spaceflight Industries, Inc., and
B1051 has launched more than three hundred primary payloads into space in less than two years. (...)

Elon Musk, SpaceX’s founder and CEO, has said the newest version of the Falcon 9 booster — called the Block 5 — could fly 10 times without any major refurbishment, and perhaps 100 times with periodic overhauls. With as many as 48 Falcon 9 and Falcon Heavy flights planned in 2021, SpaceX seems poised to have at least one Falcon booster, and possibly more, reach the 10-flight milestone this year.
The two halves of the Falcon 9 rocket’s payload fairing Wednesday were also recycled from previous missions. Two SpaceX fairing recovery vessels, each fitted with giant nets to catch the fairing shells as they fall under parachutes, were on station in the Atlantic Wednesday to retrieve the components. (...)
The 60 satellites released from the rocket a little more than an hour into the mission. An on-board camera showed the flat-panel satellites, built by SpaceX in Redmond, Washington, flying away from the Falcon 9 second stage.
With the 60 new satellites, SpaceX has shot 1,015 Starlink spacecraft into orbit to date, including prototypes not intended for commercial service. The new satellites will give SpaceX a fleet of
around 950 Starlinks currently in orbit, after subtracting the satellites that have been deorbited, according to Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics who tracks global space activity. (...)
SpaceX plans to operate an initial block of around 1,500 Starlink satellites. The company, founded by billionaire Elon Musk, has regulatory approval from the Federal Communications Commission to eventually field a fleet of up to 12,000 small Starlink broadband stations operating in Ku-band, Ka-band, and V-band frequencies. (...)
Wednesday’s mission was SpaceX’s second launch of the year.
Two more Falcon 9 flights are scheduled before the end of January.https://spaceflightnow.com/2021/01/20/spacex-sets-new-rocket-reuse-records-with-successful-starlink-launch/statystyki startu
