SpaceX preps second $500M fundraiser as Starlink & Starship make progress

According to regulatory documents seen by Prime Unicorn Index, SpaceX finished a $500M funding round begun in December 2018 and kicked off a second campaign seeking an additional $500M earlier this month.

Altogether, SpaceX appears to be on track to secure $1 billion in fresh capital in the last six months alone, a trend that that may well continue as the company pushes forth into new and capital-intensive phases of Starlink and Starship development. In Boca Chica, a flood of SpaceX engineers and technicians have descended on the area to build the first full-scale steel prototypes of Starship and the major facilities needed to support the vehicles, all from scratch. Across the West Coast of the US, a separate SpaceX team has simultaneously transitioned from prototyping and developing satellites to building a factory to mass-produce them and may be less than six weeks away from launching the first operational batch of Starlink spacecraft.

Giant rockets, giant funding

Both massive, perilous, and largely unprecedented ventures in their own right, Starship (formerly BFR) and Starlink also happen to be extremely capital-intensive, a more or less fundamental consequence of the stages of their development and expansion. Both spent many years in pure research and development phases, tinkering and experimenting with different ideas and technologies on the ground in an effort to conceptualize what exactly their final forms ought to be. This aspect of the BFR program has been extremely visible over the last three years as SpaceX and CEO Elon Musk’s goals underwent continuous semi-annual changes, often intentionally broadcasted to the public in livestreamed events.

After appearing to finally settle on the quasi-final form of BFR (renamed to Starship/Super Heavy), SpaceX has actually begun to build and test the first full-scale, integrated prototype of the spacecraft (Starhopper) and is simultaneously building what aims to be the first orbital Starship prototype. At the same time, its propulsion system of choice – known as Raptor – has entered into serial production back at SpaceX’s Hawthorne factory, while also supporting the first Starhopper hop test in early April and preparing to continue separate ground testing.

Thousands of satellites, billions of dollars

In February 2018, SpaceX successfully launched its first Starlink satellites, two prototypes meant to test a bevy of technologies the company was attempting to build (or at least utilize) for the first time. Despite hints and reports of some problems on orbit, SpaceX firmly holds that both satellites were extremely successful in their task of proving out new technologies like electric thrusters and phased-array antennas and are still safely operating today. Just four months after those prototypes launched, CEO Elon Musk took the extraordinary step of flying to Redmond, Washington to personally challenge a number of executives he believed were operating far too sluggishly. According to secondhand reports, many of them refused to expedite the program as Musk wanted them to, resulting in their immediate firings. The challenge that triggered the organizational upheaval: launch the first operational batch of Starlink satellites before the end of June 2019, twelve months away at the time.

Five months after Musk’s challenge, SpaceX submitted a request to the FCC to modify its original Starlink constellation license, halving the orbit of the first thousand or so satellites to 550 km (340 mi) and significantly simplifying the technology on the first several dozen to be launched. As a result of the strategic changes made, SpaceX is already planning to launch its first group of Starlink satellites as early as mid-May, with perhaps one or several additional launches on the books for 2019. To an extent, the first 75 Starlink satellites and their six ground stations will be a nearly full-fidelity second prototype. Instead of a minimalist development platform like Tintin A and B, the first 75 satellites should offer opportunities to actually test the operations of a large constellation of spacecraft while also demonstrating something close to the internet connectivity the full constellation is meant to offer.

Development to production

That SpaceX is attempting to raise huge amounts of capital should come as no surprise. For almost any commercial venture on Earth that is attempting to introduce a real product from nothing, the process of going from concept, design, and testing to building a final product at scale is both extraordinarily difficult and extremely expensive. Tesla famously went through “manufacturing hell” to go from Model 3 prototypes to a mass-producible finished product, while countless other ventures don’t even make it that far (i.e. vaporware). By far the most challenging aspect of this transition is moving from a phase focused predominately on development to one focused predominately on production.

Due to an extremely unorthodox approach to building the first steel Starship and Super Heavy prototypes, quite literally choosing to do so outside and without shelter, the BFR program is probably less extreme for the time being. However, the transformation needed for Starlink to progress is intense, requiring the satellite team to essentially build a factory from scratch and begin mass-producing high-performance satellites as quickly as possible. The 75-satellite buffer should ease the pain a bit and offer a sort of trial run as SpaceX makes that major transition, but the fact remains that an unprecedented number (thousands) of satellites will need to be built and launched at an equally unprecedented pace and cost-per-unit.

The $500M raised since December 2018 will likely be a major help for SpaceX’s often-shoestrung development programs. The decision to open a second $500M funding round just months after the first also bodes well for demand, indicating that it shouldn’t be long before this newest round is itself completed. Meanwhile, Starlink’s first-launch milestone is rapidly approaching, while SpaceX’s South Texas team continue to make progress on the first orbital-class Starship prototype. Onward and upwards

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.
