SpaceX has all the Starlink funding needed for an “operational constellation”
Upper-level wind shear has unfortunately scrubbed SpaceX’s first dedicated Starlink launch attempt, pushing Falcon 9 B1049’s third liftoff to no earlier than 10:30 pm EDT (02:30 UTC), May 16th.
A few hours prior to the launch attempt, SpaceX CEO Elon Musk hosted a conference call with members of the press and answered a number of questions about Starlink, providing the best look yet into the company’s newest endeavor. Topics included the advanced technologies on each Starlink satellite, their extremely unorthodox deployment method, SpaceX’s ultimate goals for the constellation, and even a few brief comments on funding.
Funding, secured
Perhaps the single most important thing Musk noted in the hour-long media briefing was his belief that SpaceX already has “sufficient capital to build an operational constellation.” It’s possible that that statement is heavily qualified, as Musk did not delve into greater detail, but it is still an incredible claim that could mean Starlink is far ahead of competing constellations and far more capital-efficient than OneWeb.
As previously discussed on Teslarati, in the last four years, OneWeb has raised $3.4B of funding, while SpaceX – a company primarily focused on building and launching rockets – has raised $2B, half of which is known to be dedicated to Starlink. OneWeb’s constellation (either 650 or 2650 satellites) cost estimate has grown quite a bit recently and stands at ~$5B. Assuming all $2B of the funding SpaceX has raised is dedicated to Starlink, that would translate to a per-satellite cost – including all infrastructure and launch – of $450,000 for the first phase (~4400 satellites).
Musk’s contextual definition of an “operational constellation” is probably more in line with the twelve 60-satellite launches he described as necessary to provide “significant [broadband] coverage”. It could also refer to the entire tranche of ~1600 Starlink satellites planned for the lower 550 km (340 mi) orbit this first batch of 60 is headed for, a number that Musk stated would offer “decent global coverage”. Either way, Starlink is almost certainly far more capital-efficient than OneWeb, LeoSat, Telesat, or any other satellite constellation with serious intentions.
The most obvious explanation for this – regardless of the satellites themselves – is simple: SpaceX owns its own closed-loop launch capability, including pads, integration facilities, an established cross-country transport network, and the rockets (Falcon) themselves. For any of the proposed satellite constellations to succeed, the manufacturers will almost invariably need to find build satellites so affordably that the cost of launch outweighs the cost of its payload. This ultimately means that launches alone could account for something like 50% of the cost of an entire satellite constellation.
Assuming Block 5 boosters can be reused at least 5-10 times each, the only real cost of an internal SpaceX launch is the hours worked, recovery fleet operations, and the expended upper stage and fairing – likely less than $30M altogether. As such, SpaceX may already be achieving its satellite cost targets on its first launch.
Deploying satellites “like spreading a deck of cards”
Meanwhile, Musk also offered some detail on the deeply unorthodox method SpaceX has chosen for spacecraft deployment once in orbit. Apparently, Starlink satellites will be deployed from Falcon 9’s upper stage by rotating the stage (presumably along its vertical axis) and simply letting go of the spacecraft. Musk used the analogy of spreading a deck of cards on a table, seemingly suggesting that they will either be released simultaneously (perhaps by stack) or with a stagger measured in milliseconds. This could create a fairly spectacular visual, forming an evenly-spaced spiral of satellites spreading out from the Falcon upper stage.
Above all else, Musk mainly seemed to be excited about Starlink, whether discussing the constellation’s long-term goals or the technology utilized on each individual satellite. Some miscellaneous facts and tidbits taken from the Q&A can be found below:
- Aside from Ka-band antennas and inter-satellite laser links, these 60 Starlink spacecraft are very close to the final spacecraft design.
- “It’s one of the hardest engineering projects that I’ve ever seen done.” – Elon Musk
- Starlink v0.9 is SpaceX’s heaviest payload ever by a huge margin, weighing in around 18,500 kg (40,800 lb). Crew Dragon is most likely in second-place, with a launch mass estimated to be around 13,500 kg.
- Combined, the solar arrays on the 60 Starlink spacecraft will produce up to 50% more power than the International Space Station’s football field-sized panels. This translates to ~180 kW, with each spacecraft thus producing around 3 kW total with an unusual single-panel array.
- Two solar array deployment mechanisms will be tested on this mission.
- “We see this as a way to generate revenue to develop more advanced rockets and spaceships. Starlink is a key component for establishing a presence on the moon and Mars.” – Elon Musk
- SpaceX sided with krypton-fueled Hall effect thrusters due to krypton costing 5-10x less than more traditional xenon propellant. SpaceX’s internally-designed and built thrusters will have an ISP of ~1500s.
- “[SpaceX has built] the most advanced phased array antenna[s] that I am aware of.” – Elon Musk
- These first 60 satellites alone will have a combined bandwidth of 1 terabit per second (125 GB/s), averaging around 17 Gbps per satellite.

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.
