SpaceX’s next commercial Falcon Heavy launch to carry Astranis rideshare satellite
Geostationary satellite communications startup Astranis has decided to move its first operational satellite launch from a SpaceX Falcon 9 to a Falcon Heavy, effectively securing the massive rocket its first commercial rideshare payload.
While not technically Falcon Heavy’s first rideshare payload and not the rocket’s first commercial rideshare launch contract, Astranis’ first 400 kg (~900 lb) MicroGEO satellite nevertheless appears set to become the first commercial rideshare payload to actually fly on the world’s largest operational rocket. Not all that dissimilar to Starlink in scope and its desire to disrupt a stagnant industry, Astranis wants to offer global communications services providers a different route to geostationary internet and broadcast solutions. Unlike SpaceX’s constellation, the startup’s MicroGEO satellites are designed for geostationary orbits ~36,000 km (~22,200 mi) above Earth’s surface and more than 60 times higher than Starlink.
However, like Starlink satellites, MicroGEO will feature exceptional density (throughput per kilogram), weighing a magnitude less than average modern geostationary communications satellites while still offering up to 10 Gbps of bandwidth. Expected to cost around $40M apiece compared to ~$100M+ for most traditional offerings, the value proposition of small Astranis satellites with 5-10 times less bandwidth admittedly gets a bit blurrier, but the company should still offer a viable alternative for companies and countries that just don’t need a massive satellite.
For example, Astranis’ first customer and the buyer behind the first MicroGEO satellite – known as Aurora 4A – is Pacific Dataport, a company focused on delivering connectivity throughout Alaska – one of the most remote and sparsely populated places on Earth. That combination of attributes makes providing broadband communication services spectacularly difficult and satellite internet the perfect (and, to an extent, the only viable) solution. However, a full $100M+ geostationary communications satellite with 50-100+ Gbps of bandwidth would likely far outweigh the needs of Alaska’s ~730,000 residents – especially when most Alaskans live in the state’s few large cities, most of which already have passable internet connectivity.
As such, it’s easy to see why a small but high-performance geostationary satellite like the kind Astranis offers might be a perfect fit for an Alaskan internet provider. While low Earth orbit (LEO) constellations like OneWeb and SpaceX’s Starlink do offer far more bandwidth and a user experience potentially as good or better than a wired connection almost anywhere on Earth, both companies first have to launch hundreds or thousands of satellites to ensure continuous coverage. Both Starlink and OneWeb are a ways away from offering continuous coverage in polar regions.
Geostationary satellites – especially those as small as Aurora 4A – offer a significant shortcut, requiring just a single satellite and ground stations in one or a few very specific regions to fully complete a communications network. Of course, thanks to universal limits posed by the speed of light, geostationary internet customers end up saddled with extreme latency (ping on the order of 300-1000ms) and strict individual bandwidth limits. But in places like Alaska, where there can easily be no alternative for the most rural residents, Astranis – or just about anything – could bring welcome relief.
Now, Astranis says it has moved the first MicroGEO satellite from a SpaceX Falcon 9 rocket to rideshare payload on Falcon Heavy’s upcoming ViaSat-3 launch, scheduled no earlier than Q2 2022. According to the startup, doing so will allow the tiny satellite to begin operations over Alaska mere days or a few weeks after launch, saving months of orbit-raising thanks to Falcon Heavy’s performance. That’s only possible because, as the Astranis press release also revealed, Falcon Heavy is scheduled to launch the 6.4 ton (~14,100 lb) ViaSat-3 and 400 kg (~900 lb) Aurora 4A satellites directly to geostationary orbit (GEO). If Falcon Heavy’s upcoming USSF-44 mission launches on schedule next month, ViaSat-3 will be SpaceX’s second direct-to-GEO mission ever and the company’s first for a commercial customer.
Assuming SpaceX is still able to recover two – or even all three – of Falcon Heavy’s side boosters while launching almost 7 tons (~15,500 lb) of satellites directly to GEO, it will also demonstrate just how much of a force to be reckoned with it really is, well and truly leaving competitors ULA and Arianespace with nowhere to hide on the open market.
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.

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.
