SpaceX’s freakishly dependable Falcon 9 continues to impress. The rocket delivered 56 Starlink satellites to Earth orbit this morning, and with a collective weight round 17.4 metric tons, it’s now the heaviest payload ever lifted by a Falcon 9 rocket.
Blastoff occurred at 4:22 a.m. ET Thursday, with the 229-foot-tall (70-meter) Falcon 9 retreating from House Launch Complicated 40 at Cape Canaveral House Pressure Station in Florida. The primary stage booster, partaking in its ninth launch, returned to Earth some 9 minutes later, touchdown safely on the Simply Learn the Directions droneship stationed northeast of the Bahamas. SpaceX later confirmed that the rocket was profitable in deploying all 56 Starlink satellites.
Routine stuff, save for the load concerned. With a mixed payload weight exceeding 17.4 metric tons, the mission marks the “heaviest payload ever flown” on a Falcon 9, SpaceX introduced in a tweet. The earlier payload weight report for Falcon 9 was set in August 2022, when the rocket lifted 16.7 metric tons to orbit. “The likeliest rationalization for the heavier payload seems to be one other iterative enchancment to Falcon 9,” in accordance to Teslarati.
When it comes to amount, the 56 satellites fall far in need of the Falcon 9 report set in January 2021 when the rocket delivered 143 satellites as a part of the Transporter-1 rideshare mission. What’s extra, SpaceX routinely launched 60 V1.0 Starlinks for a stretch working from 2019 to 2021. The upgraded V1.5 models are heavier, compelling SpaceX to launch lesser portions with its reusable Falcon 9. The medium-lift rocket’s 9 Merlin engines exert 1.7 million kilos of thrust at liftoff.

The newly launched Starlinks will now ascend to their operational orbit—a aircraft designed Starlink 5-2. That is SpaceX’s second Starlink deployment to that shell, the primary being a batch of 54 satellites launched on December 28, 2022. This shell is supposed for the corporate’s second-era Starlinks, resulting in appreciable confusion as to which type of satellite tv for pc goes up nowadays.
Second-era Starlinks, referred to as Gen2, will probably be larger than earlier variations, with added capabilities that can enable direct connectivity to cell telephones, therefore the latest association between SpaceX and T-mobile. Gen2s must also enhance Starlink protection within the decrease latitudes. The Starlink system now boasts over a million subscribers and is offered on each continent, Antarctica included.
However the heavier, bulkier Gen2s require a rocket that has but to launch: Starship. Till SpaceX’s new megarocket is deemed flightworthy, the corporate plans to launch miniature Gen2s that includes the identical kind issue as V1.5 Starlinks, permitting for launches aboard Falcon 9s.
Again in December, when SpaceX despatched the primary batch of Starlinks to the Gen2 shell, many spaceflight specialists assumed that the corporate was sending the miniature Gen2s to area. Sleuthing by Harvard-Smithsonian astronomer Jonathan McDowell put these rumors to relaxation, nonetheless, as he discovered that SpaceX continues to be launching V1.5 Starlinks to area.
Right this moment’s launch was probably the identical, with a batch of V1.5 Starlinks launched to low Earth orbit. Or at the very least, that’s my greatest guess. As McDowell tweeted on the time, “SpaceX are persistently imprecise in all the pieces they are saying.” For positive. And it doesn’t assist that SpaceX doesn’t reply to questions from the media; a lot for CEO Elon Musk’s said obsession with transparency.
On December 1, the Federal Communications Fee (FCC) accredited the launch of seven,500 Gen2s, out of SpaceX’s deliberate 29,988. The FCC is deferring its determination on the remaining models till a later time, saying the adjournment “will defend different satellite tv for pc and terrestrial operators from dangerous interference and keep a protected area setting, selling competitors and defending spectrum and orbital sources for future use.”
SpaceX not too long ago carried out a full moist costume rehearsal of Starship, so it might solely be a matter of time earlier than the corporate can begin launching its outsized Gen2 Starlinks to orbit.
