SpaceX to in-house mass production of Starlink internet satellite hardware

Published

on

SpaceX is rapidly expanding it’s Starlink internet constellation development to prepare for full-scale production and aims to bring nearly every major piece of satellite and network hardware and software in-house, according to details revealed in dozens of job postings.

While not explicit, this appears to indicate a significant convergence of multiple possible paths to an operational constellation. Put simply, SpaceX now intends to build every single major component of its 4400+ satellite network in-house. It’s almost easier to list the things SpaceX does not mean to build themselves, but here’s a stab at the components to be built in-house: satellite structures, laser (optical) data interlinks, on-orbit phased array antennae, digital signal processor (DSPs) software and hardware to aim those antennae, solar arrays, battery systems, power electronics, custom integrated circuitry and systems on a chip (SoCs), user terminals and larger gateways, network operations, production automation, autonomous satellite constellation management, and much, much more.

While entire articles could be spent describing the complexities of every single one of the above subsystems, the point is that SpaceX appears to have gone all-in on building its own satellite constellation, departing from stances in the past that appeared to leave room for subcontracting and outsourcing the production of major parts of the network, particularly with respect to ground terminals and gateways. Postings for ground station and user terminal engineers describe a goal of medium to high volume in-house production of the critical network and customer-facing hardware, and an entry into the production of high volume consumer technology would be a truly eclectic and unprecedented step for a company theoretically focused on launch vehicle development and production and sustainable Mars colonization.

If anything, they speak to the truly vertical nature of SpaceX. Many technology development production companies would simply accede and accept the best subcontractor/outsourcing bid when entering into new territory truly outside of their internal expertise. SpaceX engineers and managers, however, seem to have concluded that the vast majority of hardware and corporate expertise they could co-opt is just not satisfactory for the purpose of building a paradigm-shifting satellite constellation; or as CEO Elon Musk noted in 2015, to “revolutionize the satellite side of things, just as we’ve done with the rocket side of things.”

This new (and, in retrospect, unsurprising) trailblazing attitude also helps to explain the marginal delay to Musk’s original 2015 schedule, which estimated initial constellation operations (i.e. a few hundred satellites launched) would begin around 2020. Approximately a year later, SpaceX had built rough prototypes in the form of the original Microsat 1A and 1B twins. This initial foray into independent, long-term communications smallsats was shuttered fairly quickly, and neither of the demo satellites were launched. Instead, SpaceX dove back into prototype design and development, culminating roughly two years later with the March 2018 launch of two dramatically improved prototypes, known as Tintin A and B (or Microsats 2A and 2B in FCC licenses).

It seems probable that the source of this delay lay in an internal decision to dramatically reconfigure the internet constellation for far more in-house development, whereas the original Microsats were likely pieced together from a range of components derived from SpaceX’s Cargo Dragon program or more simply from commercial off-the-shelf (COTS) offerings. Instead, SpaceX’s Starlink development offices in Redmond, Washington and throughout California are staffed with as many as 400 to 500 employees dedicated in large part to the nascent program, similar (if not larger) in scale to OneWeb, the only noteworthy satellite internet competitor at present.

If SpaceX’s decision to push back Starlink’s operational debut by a few years in order to bring in-house almost every single critical subcomponent of Starlink pays off, the company could begin launching finalized satellites en masse as early as late 2019/early 2020, with a goal of offering limited service by 2021 per comments made by CEO Elon Musk. Starlink is likely being brought almost entirely in-house because Musk or other high-level executives and engineers see major room for improvement, improvements that could lower the cost of and improve the performance of lightweight communications satellites by an order of magnitude.

It will likely take a bit longer than initially expected, but SpaceX may yet still pave their path to Mars colonization with profits derived from a wildly successful and disruptive entrance into the broadband market.

How SpaceX Is raising Raptor’s sea-level thrust while holding engine mass steady

Published

on

Credit: SpaceX

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:

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 Assisted Driving expands to tenth EU country

Published

on

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’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.

Tesla starts showing how FSD will change lives in Europe

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 expands Robotaxi geofence in Houston with an ode to SpaceX merger

Published

on

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.
