A new generation of space race is currently underway, but this time it’s not a race to determine which country will reach orbit first, but rather which spaceflight company will successfully reach orbit first with the world’s second generation of super-heavy launch vehicles (SHLVs).

SpaceX, United Launch Alliance (ULA),  Blue Origin, and NASA all have plans to build and operate their own SHLV rockets. All entities are deep into design and development and are, for the most part, at various stages of assembly and integration of their first flight hardware, offering an excellent opportunity to compare and contrast the differing approaches at work.

While NASA and ULA are developing rockets featuring an expendable single core supported by solid rocket boosters, SpaceX and Blue Origin have developed reusable designs that will utilize an enormous single core booster powered by multiple engines.

SpaceX: Starship/Super Heavy

Currently the world’s only builder and operator of a super-heavy launch vehicle (Falcon Heavy), SpaceX’s next-generation rocket is undoubtedly the most well known.

The design of SpaceX’s next-generation Starship & Super Heavy rocket is by far the most ambitious. According to company CEO Elon Musk, the new rocket will be comprised of a massive booster deemed “Super Heavy”, featuring as many as 35 Raptor engines capable of producing a total of more than 70,000 kN (15.7M lbf) of thrust at liftoff. The rocket’s upper stage is known as Starship and will be a fully-reusable crew and cargo transport vehicle powered by up to 6 Raptors – 3 sea level-optimized engines and 3 vacuum-optimized engines.

Technically speaking, this Raptor is the smaller (sea-level) version of the engine. (SpaceX)

Per a September 2018 design update, Starship and Super Heavy will stand 118 meters (387ft) tall and will be able to launch a minimum of 100 metric tons (220,000 lb) to Low Earth Orbit in a fully reusable configuration, in which both the booster and ship return to Earth for recovery and reuse. On its own, Starship will stand at least 55 meters tall and feature a massive payload bay (or crew section) with a usable volume of no less than 1000 cubic meters (~35,000 ft3). The now-outdated 2018 design also featured almost 90 cubic meters of unpressurized cargo space, a bet less than nine times as much SpaceX’s operational Cargo Dragon spacecraft.

Although CEO Elon Musk has stated that the design of Starship’s legs and control surfaces has since changed, including the addition of legs to Super Heavy boosters, the upper stage’s 2018 design featured two actuating canards and fins/legs, two of which actuate a bit like flapping wings.

Currently, SpaceX is actively building two orbital Starship prototypes at two separate facilities in Cocoa Beach, Florida and Boca Chica, Texas, as well as an unusual low-fidelity prototype known as Starhopper. Outfitted with a lone Raptor engine (SN06), Starhopper very recently completed a successful 20-meter hop, also the vehicle’s first untethered test flight.

Just a few hours after Starhopper completed its first untethered flight test, SpaceX CEO Elon Musk posted two videos showing the rocket’s flight debut from liftoff to landing. (SpaceX/Elon Musk/Teslarati)

According to Musk, Starhopper is being prepared for a second untethered flight as early as August 16th, in which the rocket will reach a maximum altitude of up to 200 meters (650 ft) and perform a small divert, landing on an adjacent landing pad. Musk also has plans to present a major update on the status of Starship during an official event, scheduled to occur on August 24th in Boca Chica, TX. Aside from hundreds of disconnected snippets in the form of Musk’s prolific tweets, this will mark the first official presentation on Starship since SpaceX made the radical leap from carbon fiber to stainless steel.

SpaceX has taken a truly unprecedented approach to Starship and Super Heavy production and is currently assembling two full-scale Starship prototypes (Mk1 and Mk2) outside with little to no cover, although some spartan covered production facilities are simultaneously being built.

Blue Origin: BE-4 for all

On the near-opposite side of the spectrum, Blue Origin and ULA have formed a partnership in the sense that both companies will ultimately use the same Blue Origin-built engines to power the boosters of their own next-generation launch vehicles. ULA has decided to acquire Blue-built BE-4 engines for its Vulcan Heavy rocket, motivated primarily by the fact that the company will no longer be able to legally import the Russian-built RD-180 used on Atlas V after 2022 as a result of US sanctions.

First and foremost, though, Blue Origin is developing BE-4 as the primary propulsion of the company’s own two-stage super heavy-lift rocket, known as New Glenn. New Glenn’s first stage will be powered by 7 of the extremely powerful oxygens, utilizing liquefied natural gas (LNG) and liquid oxygen to produce at least 2,450 kN (550,000 lbf) of thrust. Altogether, New Glenn will lift off with a maximum thrust of 17,100 kN (3.85m lbf) of thrust at sea level.

Unintuitively, New Glenn will actually produce a full 33% less thrust than SpaceX’s Falcon Heavy (~23,000 kN or 5.1M lbf) at liftoff but will likely be able to crush Falcon Heavy’s performance to higher orbits while still in a reusable configuration. This is thanks in large part to the greater efficiency of a single-core rocket, as well as the greater efficiency of its methane-powered BE-4 boost-stage engines and hydrogen-powered BE-3U upper stage engines. According to Blue, New Glenn will be able to launch 45,000 kg to LEO and 13,000 kg to GTO while still recovering the booster, compared to Falcon Heavy’s 8,000-10,000 kg GTO performance.

New Glenn will stand 95 meters (313 ft) tall and feature the largest payload fairing in operation, measuring 7m (23 ft) wide and in diameter. New Glenn’s booster will follow in the footsteps of Blue Origin’s relatively tiny New Shepard and will rely on actuating fins for in-atmosphere maneuvering, as well as two fixed wing-like strakes that will partially function as wings during recovery. New Glenn will also feature six retractable landing legs and land on a modified ship, much like SpaceX’s Falcon family.

While Blue Origin has scarcely published a word or photo on New Glenn’s production progress since its September 2016 reveal, the company does provide small updates on the status of its BE-4 engine every few months, including a photo of a recent full-power engine test completed on August 2nd at Blue’s Van Horn, Texas facilities.

ULA: Vulcan Heavy

ULA’s next-generation Vulcan Heavy rocket will feature two such BE-4 engines but will be fully expendable for at least 4-6 years after its nominal 2021 launch debut. ULA will continue to lean on their well-worn preference for supplementing liquid propulsion with 2-6 strap-on solid rocket boosters (SRBs), adding as much as ~12,000 kN (2.7M lbf) to booster’s two BE-4s, themselves producing 4,800 kN (1.1M lbf) of thrust

In its largest configuration, Vulcan Heavy will stand 69.2 m (227 ft) tall – just a tad shorter than Falcon 9 – and be capable of launch up to 15 tons (~33,000 lb) to GTO and 30.3 tons (67,000 lb) to LEO.

ULA CEO Tory Bruno recently took to Twitter to provide a small Vulcan development update, revealing that the first Vulcan booster was recently completed at the company’s Decatur, Alabama factory. This particularly booster is a structural test article (STA) and will never fly, but it’s still a huge milestone for ULA’s next-generation rocket.

The photos give a great idea of scale as the Vulcan booster is pictured alongside one of the company’s significantly smaller Atlas V booster, 3.8m compared to Vulcan’s 5.4m diameter.

Ultimately, this modern space race will hopefully benefit the spaceflight industry as a whole, particularly with respect to the introduction of New Glenn, hopefully giving SpaceX’s reusable Falcon 9 and Heavy rockets some real technological competition. ULA’s Vulcan is aiming for a H1 2021 debut, followed by New Glenn in late-2021 or 2022.

SpaceX’s Falcon Heavy is already operational and just completed its third launch in June 2019, with several more launch contracts on the books from late-2020 onwards. Its Starship/Super Heavy rocket is in a bit of a chaotic state at the moment, but CEO Elon Musk believes an orbital launch attempt could come as early as early-2020. Meanwhile, NASA is very slowly making its way to the launch debut of its Space Launch System (SLS) rocket, likely to slip into 2022.

With any luck, the early 2020s will be greeted by the operational debuts of two, three, four, or even more extremely capable rockets offering largely unprecedented launch costs. For now, we wait…

Tesla faces Full Self-Driving pushback in EU over ‘speeding’

Published

on

Credit: Tesla

A new report from Reuters claims that a transport authority in Sweden is pushing back against the approval of Tesla’s Full Self-Driving suite because it will travel over speed limits.

The report says the Swedish Transport Administration (TRV) recommends the European Union votes against FSD’s approval. TRV believes it should not be approved until Tesla disables FSD’s ability to speed.

TRV sent a letter to the European Union’s Technical Committee on Motor Vehicles (TCMV), which is set to meet on June 30 to discuss the potential approval of the Tesla FSD suite in the country. Tesla, which has received various approvals in Europe over the past two months, has not provided a comment.

Tesla Full Self-Driving gets first-ever European approval

Teslas operating on FSD do travel over the speed limit, depending on the Speed Profile that is chosen. Drivers have the ability to disengage FSD at any point; Tesla specifically states that those supervising the suite are responsible for its actions.

Let’s cut to the chase: humans operating any vehicle speed almost daily in the United States. Realistically, speed limits in the U.S. are more frequently treated as speed minimums. However, other countries are different, and driving behaviors are less aggressive.

TRV believes that “allowing automated systems to systematically exceed legal speed limits…risks undermining both the legal framework and the expected safety benefits of ​vehicle automation,” the report stated. It’s surprising that Tesla has not received this claim from other countries previously.

This could be a good argument to bring Max Speed back, the setting that previously allowed the driver to choose the absolute fastest the car would travel.

This would still put the responsibility of supervision in the hands of the driver. It would allow the driver to choose whether the car would travel over the speed limit or not, acknowledging that they set the speed, and if they get pulled over, there would be no ability to argue it.

However, it does not seem as if this is something Tesla will do, especially considering many U.S. drivers have requested the feature in an effort to eliminate speeding or at least tone it down. The company has not shown any interest in bringing it back.

Tesla has approvals for FSD in Europe in Estonia, Lithuania, Denmark, the Netherlands, and Belgium.

Tesla teases greater Grok FSD integration and ‘Banish’ feature ‘in about 3 months’

Published

on

Tesla is going to let you guide Full Self-Driving with Grok in 3 months, CEO Elon Musk confirmed on X.

The response from Musk, which revealed Tesla plans to allow drivers to effectively control the car and its navigation more explicitly using Grok, puts the feature for about September.

A Tesla owner said that Full Self-Driving is great, but owners should be able to “converse with Grok like we can with an Uber driver.” She then used examples like, “Grok, turn right here,” and “Drop us off right here, we’ll walk due to traffic,” and finally,” Drop at entrance first, then park far away.”

Coincidentally, the final piece of dialogue would also mean features like Banish are potentially on the way soon.

Banish is also referred to as “Reverse Summon,” and would enable the car to self-park while dropping occupants off at their destination.

This would be a great way to improve the overall experience while supervising FSD. Navigation is already a major painpoint that many owners complain about. Manual overrides when a maneuver is requested or canceled (like using the turn signal stalk to override a navigation route), do not always work.

The feature could be especially useful in street parking scenarios in a city, where spots are sometimes tough to come by. Many of us who grab dinner in a more populated area will park a street or two over from wherever we’re going, because sometimes you know that’s the best you will get. If a driver using FSD could say, “Hey Grok, turn right here on Queen St. and park in that open spot on the right,” it could save a lot of confusion FSD might have on its own.

Musk teased that a similar feature was “coming” back in February:

Tesla Full Self-Driving set to get an awesome new feature, Elon Musk says

It is certainly surprising that Tesla is doing it at this point. The company’s more recent moves have been more evident of taking control and inputs away from humans and putting them in the AI’s hands more frequently. The biggest example of this was taking away Max Speed in AI4 cars, giving us Speed Profiles, and not having any input on the fastest speed the car will travel.

Of course, giving navigation preferences to Grok is availble already in Teslas, but not at the drop of a hat. Instead, you can suggest a certain route at the beginning of your drive.

Here’s an example of that from December:

Finally, the original post that Musk responded to mentioned a parking preference after dropping off the occupants, which describes the Banish feature that Tesla has teased for years.

We’re not sure if Musk was responding more to the ability to guide the car with Grok, or whether he also was including Banish in the three-month prediction timeframe.

Tesla Cybercab has one important piece that AI4 cars might need for FSD

Published

on

A close-up image of a Cybercab engineering vehicle in Peabody, Massachusetts, reveals a compact triangular side repeater camera housing equipped with an integrated washer mechanism.

This seemingly small hardware addition could prove to be one of the most critical components for achieving reliable, unsupervised Full Self-Driving (FSD) — not just for the dedicated Robotaxi but potentially for existing AI4-equipped vehicles as well.

The washer system’s importance cannot be overstated in Tesla’s vision-only autonomy approach. Cameras are the sole sensory input for the neural networks powering FSD, constantly interpreting the environment for safe navigation. In real-world conditions, however, lenses quickly accumulate rain, snow, mud, dust, or road spray.

Many of us Tesla owners, especially those who deal with any sort of winter weather at all, know the all-too-common alert that pops up when cameras are obstructed:

Even brief obstructions can drop perception confidence, trigger safety disengagements, or force the vehicle to pull over, although these are relatively rare. Instead, most of the time, the camera will need a wipe from the owner next time they stop the car.

But unlike human drivers who can manually clear their view, a Robotaxi operating 24/7 without a steering wheel or mirrors must maintain pristine vision autonomously. The Cybercab’s side repeater washer delivers targeted cleaning bursts precisely where needed for merging, lane changes, and blind-spot monitoring — functions that demand uninterrupted visibility from the external cameras:

This hardware directly tackles a known pain point in current FSD deployments. Owners frequently report camera-related alerts during inclement weather, which is understandable, but needs to be solved for a true autonomous experience.

For a production Robotaxi fleet aiming for high utilization and minimal downtime, robust washer systems represent a foundational reliability upgrade; essentially, they’re a must-have. Early sightings suggest the design may extend to rear cameras as well, creating a comprehensive cleaning architecture that keeps the entire vision suite operational in harsh environments.

Without it, even the most advanced neural nets struggle when their “eyes” are compromised.

What Does This Mean for AI4 Cars?

This Cybercab detail raises timely questions for AI4 cars already on the road. While Hardware 4 delivers superior compute and camera resolution compared to earlier versions, production models typically lack dedicated side and rear washers. Tesla has included them on Model Y robotaxis that it is using in the fleet:

Tesla Robotaxi has a highly-requested hardware feature not available on typical Model Ys

As Tesla refines unsupervised FSD for broader release, the gap in environmental resilience becomes evident. Software improvements can help mitigate issues, but they cannot fully replace physical cleaning in heavy rain or muddy conditions. Analysts and owners increasingly speculate that AI4 vehicles may eventually require similar washer retrofits — or a future AI4.5 variant — to match the Cybercab’s all-weather readiness and support the same level of autonomy.

As testing progresses, the Cybercab’s washer mechanism highlights Tesla’s pragmatic focus on real-world robustness. It may well become the hardware piece that determines how quickly and reliably FSD scales from prototypes to everyday vehicles.
