Update #2: SpaceX has successfully delivered Starlink 4-4 – batch of 52 new satellites – to low Earth orbit (LEO), completing the first of three back-to-back Falcon 9 launches scheduled less than three days apart.
Starlink 4-4 marks the 98th successful Falcon landing, the first time SpaceX has performed a non-polar Starlink launch from its West Coast pad, and the first time a Falcon 9 booster has completed 11 orbital-class launches and spaceflights. Up next, SpaceX is scheduled to launch Turkey’s Turksat 5B geostationary communications satellite out of its Cape Canaveral, Florida LC-40 pad. Falcon 9 could lift off as early as 10:58 pm EDT, Saturday, December 18th (03:58 UTC 19 Dec) – just 15 hours after Starlink 4-4. Set in September 2021, SpaceX’s current record is two launches in ~44 hours.
Update: SpaceX’s second dedicated West Coast Starlink launch has slipped to no earlier than (NET) 1:24 am PDT (09:24 UTC) on Saturday, December 18th. Headed to an orbit unusual for a Vandenberg Space Force Base launch, Starlink 4-4 could now lift off just 18 hours before a different SpaceX mission – Turksat 5B – lifts off from the opposite side of the country.
Barring delays to Cargo Dragon’s CRS-24 space station resupply mission, which remains scheduled for 5:06 am EDT on December 21st, that means that SpaceX is now on track to launch three Falcon 9 rockets in three days (less than 73 hours).
SpaceX appears to be on track to round out a record-breaking year with three Falcon 9 launches in four days.
With the diverse trio of missions, SpaceX will orbit another batch of laser-linked Starlink satellites, deliver a large communications satellite to geostationary transfer orbit (GTO), send a Dragon to space for sixth time this year, and break at least two company records. The first mission, known as Starlink 2-3, could occur as early as the morning of December 17th, kicking off an incredibly busy period of launches – and not just for SpaceX.

Starlink 2-3
Referring to the fact that the mission will be the third launch for the second distinct group or ‘shell’ of Starlink satellites, Starlink 2-3 will actually be the second dedicated launch to a semi-polar orbit, leapfrogging Starlink 2-2 for unknown reasons after Starlink 2-1’s successful September launch. Originally scheduled to launch in mid-October, SpaceX was forced to stand down just a few days before liftoff for unknown reasons and at least a week or two of delays soon put Starlink 2-3 at risk of clashing with the company’s upcoming NASA DART launch, which unsurprisingly took precedence. SpaceX successfully launched the Double Asteroid Redirection Test (DART) mission on November 24th.
Late on December 13th, tugboat Scorpius likely departed Port of Long Beach with SpaceX drone ship Of Course I Still Love You (OCISLY) in tow – a fairly airtight confirmation that a SpaceX launch is just a handful of days away. Based on safety Notices to Airmen and Mariners (NOTAMs/NOTMARs), Starlink 2-3 is scheduled to launch sometime between 12am and 6am PDT (UTC-8) on Friday, December 17th. If accurate and SpaceX stays on schedule, Falcon 9 could lift off from the company’s Vandenberg SLC-4E launch pad with Starlink 2-3 in tow just 22 days after a different Falcon 9 rocket launched DART – smashing the pad’s current 36-day turnaround record by almost 40%.

Aside from drastically increasing the maximum theoretical launch cadence SpaceX’s West Coast pad is capable of supporting, Starlink 2-3 is also expected – as it was in October – to fly on Falcon 9 booster B1051, potentially making the mission the first time a liquid rocket booster has completed eleven orbital-class launches. B1051 debuted in March 2019, sending an uncrewed Crew Dragon on its way to orbit for the first time. Before SpaceX’s Starlink launch cadence fell off a cliff in the second half of 2021, B1051 completed its tenth launch on May 9th, 2021, averaging one launch every ~80 days over a two-year career. Starlink 2-3 will be B1051’s first launch in 7 months and eleventh launch in 33 months.
Turksat 5B
As early as 11:58 pm EDT (UTC-5) on Saturday, December 18th, another Falcon 9 rocket is scheduled to launch Turkey’s Turksat 5B geostationary communications satellite from SpaceX’s Cape Canaveral LC-40 pad. There’s a good chance that former Falcon Heavy booster B1052 – recently converted into a Falcon 9 after more than two years in storage – will be assigned to the mission, which is set to be SpaceX’s 30th orbital launch in 2021.

CRS-24 and more!
Finally, a different Falcon 9 (possibly B1062 or even a new booster entirely) is scheduled to launch a new Cargo Dragon 2 spacecraft on CRS-24 – potentially the company’s 23rd operational International Space Station (ISS) resupply run since October 2012. It will be Falcon 9’s sixth Dragon launch of 2021 – another record for SpaceX and the spacecraft. If the schedule holds, CRS-24 could lift off as early as 5:06 am EDT (UTC-5) on Tuesday, December 21st and would be SpaceX’s third Falcon 9 launch in roughly 100 hours (a little over four days). CRS-24 is expected to be SpaceX’s 31st and final launch of 2021, beating out the 26-launch record it set just last year.
However, the rest of the world isn’t quite finished. As early as the day after CRS-24, an Ariane 5 rocket is scheduled to launch the almost $10 billion, NASA-built James Webb Space Telescope (JWST). Decades in the making, JWST will be the single most expensive payload and the largest space telescope ever launched and is functionally irreplaceable and hard (but not impossible, if the political will is there) to repair, making it perhaps the most universally nerve-wracking uncrewed launch in the history of spaceflight.

SpaceX set to launch astronauts and a classified Falcon Heavy mission on the same day
SpaceX plans three launches Thursday, including Crew-13 astronauts and Falcon Heavy’s first classified NRO mission.
SpaceX is lining up one of the busiest single days in its history, and the company offered a preview on Wednesday morning with a simple post on X: “Sunrise at pad 40.” The video and photos show Falcon 9 standing at Space Launch Complex 40 at Cape Canaveral, roughly a day before it is scheduled to carry four astronauts to the International Space Station.
That launch is only the first of three SpaceX missions planned for Thursday, October 1, across both coasts.

Crew-13 is targeting liftoff at 11:10 a.m. ET, with a backup opportunity Friday at 10:47 a.m. ET. NASA astronaut Jessica Watkins will command the mission, with NASA’s Luke Delaney as pilot and Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov serving as mission specialists. According to NASA, Dragon is set to dock with the forward port of the station’s Harmony module around 8 p.m. ET, less than nine hours after launch. Watkins is the only member of the crew who has flown before, and Kutryk will become the first Canadian to reach orbit through NASA’s Commercial Crew Program.
The Falcon 9 booster is flying for the third time after supporting Crew-12 and a Starlink mission, and it will attempt a landing at Landing Zone 40 beside the pad. That site made its debut in February when the Crew-12 booster touched down there, as Teslarati reported at the time. Crew-13 will relieve the Crew-12 astronauts, who have been aboard the station since the middle of February.
On the West Coast, another Falcon 9 is scheduled to lift off from Vandenberg Space Force Base in a window running from 2:18 to 3:16 p.m. ET, a flight NASASpaceflight lists as a Transporter rideshare mission.
The day is set to close at 11:53 p.m. ET, when Falcon Heavy launches from Launch Complex 39A with NROL-97, the first National Reconnaissance Office payload ever to fly on the rocket. SpaceX rolled the vehicle out to the pad Tuesday night. Its two side boosters, which previously flew GOES-U, ViaSat-3 F3 and NASA’s Roman Space Telescope, will return to Landing Zones 1 and 2, while a new center core will be expended in the Atlantic. The Roman launch took place on August 30, so NROL-97 will come barely a month later as Falcon Heavy’s third flight of 2026 and 14th overall.
NASA taps SpaceX to launch the telescope that could unlock new worlds
If all three Florida boosters land as planned, it would be the first time the Space Coast has seen landings at LZ-40, LZ-1 and LZ-2 on the same day, according to the Orlando Sentinel, which has warned residents in Brevard, Orange and Volusia counties that more than one sonic boom is possible.
The schedule arrives just three days after Starship reached orbit for the first time on Flight 14 from Starbase, Texas, deploying 26 Starlink V3 satellites. If Thursday’s missions stay on time, SpaceX will have flown Starship, Falcon 9 and Falcon Heavy from four different pads in about four days.
Crew-13 is also the start of a longer run for Dragon. NASA recently added Crew-15, Crew-16 and Crew-17 to SpaceX’s contract in a $946 million modification, keeping Dragon as the agency’s only operational ride to the station while Boeing’s Starliner remains grounded.

Tesla Cybercab and Semi have more in common than you might think
Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.
The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.
🚨 Tesla designed the integrated thermal systems for Cybercab and Semi at the same time as the vehicles were both in development
Tesla wanted to build one thermal system that worked with both vehicles, apart from small modifications.
Semi and Cybercab share parts 🤯 pic.twitter.com/KmzSsUbrcg

Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:
“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”
Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”
Priestley also highlighted a practical payoff of the indirect design:
“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”
This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.
The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.
This thermal system is also shared with Cybercab – one thermal system for both our most efficient vehicle & our biggest vehicle
— Tesla Semi (@tesla_semi) September 25, 2026
Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.
Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.
For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.

Elon Musk weather update tips Tesla Roadster speculation into Plaid Mode
Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.
For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.
However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.
“Because this event can only be held outdoors…”
Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”
With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.
Roadster event update
We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

FAA Airspace Restriction
The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.
Tesla Roadster event requires restricted airspace, and the FAA obliges
Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.
Elon Admits High Winds
“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.
All signs are pointing toward an aerial demonstration for the Roadster.
