SpaceX’s first “next-gen” Starlink satellites are suspiciously familiar
In a strange twist, SpaceX says that its next Starlink mission will launch 54 satellites into low Earth orbit (LEO), implying that they’re roughly the same size as the V1.5 satellites it’s already launching – not the larger V2 or V2 Mini satellites discussed in recent FCC filings.
However, the data SpaceX provided also shows that those 54 satellites are headed to an orbit that only matches the company’s next-generation Starlink Gen2 (V2) constellation. While SpaceX quietly indicated that a V1.5-sized satellite was an option for early Gen2 launches in a supplemental October 2022 filing [PDF] with the FCC, it’s still unclear why SpaceX would prioritize launching V1.5-sized V2 satellites while its V1 constellation remains unfinished.
Adding to the confusion, in November 2021, CEO Elon Musk strongly implied that the inefficiencies of smaller Starlink V1.x satellites were so significant that they could risk bankrupting SpaceX if the company couldn’t start launching larger V2 satellites on its next-generation Starship rocket by the end of 2022. What, then, is the purpose of SpaceX’s imminent “Starlink G5-1” launch?

The name alone is confusing. Using the same shorthand as past Starlink V1 launches, “G5-1” refers to the first launch of “Group 5” of a constellation. “Group” here is synonymous with “shell,” which describes a set of satellites that share the same orbital inclination (the angle at which the orbit crosses the equator) and a similar orbital altitude. Of SpaceX’s three approved constellations, only one has five shells, and that shell can only exist at 97.6 degrees, not 43 degrees. SpaceX’s Gen2 constellation technically has nine planned shells, but the FCC has only partially approved three of those shells, one of which is at 43 degrees.
Ignoring the obtuse name, one possibility is that aspects of Starlink V2 satellite upgrades are not explicitly tied to the much larger size of those satellites and can be applied to SpaceX’s first-generation Starlink constellation without requiring a modified FCC license. If SpaceX wanted to add larger satellites to its V1 constellation or change the frequency bands they use, it would almost certainly have to seek a modified license from the FCC, which could take months.
There is no evidence SpaceX has done so, and any attempt would produce public documentation. The 43-degree inclination SpaceX’s mysterious “Starlink G5-1” launch is targeting also rules out any involvement in its V1 constellation, which only has approval for satellites between 53 and 97.6 degrees.
Aside from the unlikely possibility that details about the Starlink 5-1 mission are somehow incorrect or an artifact of a messy launch licensing process, there is at least one other unlikely explanation. In October 2018, the FCC granted SpaceX permission to launch a very low earth orbit (VLEO) constellation of 7518 Starlink satellites with dimensions similar to satellites that make up the 4408-satellite constellation the company is currently launching. More than four years later, SpaceX has yet to begin launching its approved VLEO constellation.
In November 2022, SpaceX told the FCC it intended to combine its Starlink VLEO and Starlink Gen2 constellations by adding V-band antennas to some of the almost 33,000 Gen2 satellites it hoped to launch – a move that would reduce the total number of Starlink satellites SpaceX needs to launch. Around the turn of the month, the FCC partially granted SpaceX’s Starlink Gen2 license, adding unprecedentedly strict requirements and only permitting the launch of 7500 of 33,000 planned Gen2 satellites to a limited set of inclinations (33, 43, and 53 degrees).
Perhaps, then, the uncertainty created by the FCC’s strange partial Gen2 grant made SpaceX change its mind about a dedicated Starlink VLEO constellation. However, without a license modification, SpaceX’s VLEO constellation is stuck with the same smaller (and potentially bankruptcy-inducing) satellites that its CEO believes make the first Starlink V1 constellation unsustainable. SpaceX also has less than two years until its VLEO constellation crosses its first deployment milestone, at which point the company will need to have launched half of it (3759 satellites) to avoid penalties from the FCC – up to and including the revocation of its license.
Despite the numerous reasons it wouldn’t make sense for Starlink 5-1 to be SpaceX’s first Starlink VLEO launch, almost 2500 of SpaceX’s approved VLEO satellites were intended to operate in a 336-kilometer (~209 mi) orbit inclined by 42 degrees – oddly similar to the 338-kilometer (~210 mi), 43-degree orbit SpaceX appears to be targeting with Starlink 5-1.
A surprise VLEO launch is a very unlikely explanation, but it’s only marginally stranger than the alternatives: that Starlink 5-1 is a V1-sized V2 launch with no prior mention or warning, a V1 launch to an orbit that would explicitly violate SpaceX’s Starlink V1 FCC license, or a paperwork error that has propagated so far that SpaceX distributed incorrect orbit information (which could threaten other satellites and rockets) less than two days before liftoff.
Thankfully, there is one last explanation – raised after this article was published – that appears to be much more likely. In response to a tweet summarizing these claims, astrophysicist Jonathan McDowell noted that SpaceX had, in fact, mentioned a third smaller Starlink V2 satellite variant in an October 2022 FCC filing that fell mostly under the radar. In that filing, SpaceX told that FCC it was developing three variants, not two. The smallest variant was said to weigh 303 kilograms and featured dimensions seemingly identical to SpaceX’s existing V1.5 satellites, which are estimated to weigh around 307 kilograms. SpaceX also stated that initial Falcon 9 launches will carry “approximately twenty to sixty satellites,” again confirming that V2 satellites could be about the same size and shape as V1.5 satellites.
SpaceX’s decision to develop a V1.5-sized version of V2 satellites makes little sense in the context of Musk’s implicit claims that problems inherent to its smaller V1 satellites threaten the company’s solvency. It’s clearer than ever that the SpaceX CEO may have been stretching the truth of the matter to craft an existential threat that might encourage employees to work longer hours. Still, developing and launching a V1.5-sized V2 satellite variant and beginning to launch those satellites while SpaceX’s Starlink Gen1 is more than 25% incomplete is confusing at best.
Regardless of what it’s carrying or why, a SpaceX Falcon 9 rocket is scheduled to launch Starlink 5-1 out of Florida’s Cape Canaveral Space Force Station (CCSFS) no earlier than 4:40 am EST (09:40 UTC) on Wednesday, December 28th.
SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.
Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.

It looks a lot like a rocket — we all remember the shape in Austin 🤣 https://t.co/cFOPEuiJ4u

The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.
The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.
Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.
Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.
Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.
Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.
Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.
The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.
Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
