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 withdrawing from House Launch Advanced 40 at Cape Canaveral House Power Station in Florida. The primary stage booster, partaking in its ninth launch, returned to Earth some 9 minutes later, landing 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 previous payload weight record for Falcon 9 was set in August 2022, when the rocket lifted 16.7 metric tons to orbit. “The likeliest clarification for the heavier payload seems to be one other iterative enchancment to Falcon 9,” according 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 items 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-technology Starlinks, resulting in appreciable confusion as to which sort of satellite tv for pc goes up today.
Second-technology Starlinks, often called Gen2, shall be greater than earlier variations, with added capabilities that can permit direct connectivity to cell telephones, therefore the latest arrangement between SpaceX and T-mobile. Gen2s also needs to improve Starlink coverage in the lower latitudes. The Starlink system now boasts over one million subscribers and is out there 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 consultants assumed that the corporate was sending the miniature Gen2s to area. Sleuthing by Harvard-Smithsonian astronomer Jonathan McDowell put these rumors to relaxation, nevertheless, as he learned that SpaceX is still launching V1.5 Starlinks to space.
At present’s launch was possible the identical, with a batch of V1.5 Starlinks launched to low Earth orbit. Or no less than, that’s my finest guess. As McDowell tweeted on the time, “SpaceX are persistently obscure in the whole lot they are saying.” For certain. And it doesn’t assist that SpaceX doesn’t reply to questions from the media; a lot for CEO Elon Musk’s stated obsession with transparency.
On December 1, the Federal Communications Fee (FCC) approved the launch of seven,500 Gen2s, out of SpaceX’s deliberate 29,988. The FCC is deferring its determination on the remaining items 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 performed a full wet dress rehearsal of Starship, so it could solely be a matter of time earlier than the corporate can begin launching its outsized Gen2 Starlinks to orbit.
