SpaceX, Blue Origin, and ULA make major progress in commercial megarocket space race
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.
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 The now-outdated 2018 design also featured almost 90 cubic meters of unpressurized cargo space, a bet less than nine times as much SpaceX’s operational Cargo Dragon spacecraft.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.
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’s troublesome Auto Wipers get a major upgrade
Tesla has quietly deployed a major over-the-air (OTA) update across its entire fleet, implementing a new patent that could finally solve one of the most complained-about features in its vehicles: the Auto Wipers.
One of Tesla’s most complained-about features is that of the Auto Wipers, but they have recently received a major upgrade that impacts every vehicle in the company’s fleet, a company executive confirmed.
Tesla has quietly deployed a major over-the-air (OTA) update across its entire fleet, implementing a new patent that could finally solve one of the most complained-about features in its vehicles: the Auto Wipers.
Confirmed by senior Tesla AI engineer Yun-Ta Tsai on April 10, the improvement is based on patent US 20260097742 A1. It introduces an “energy balance model” that adds a tactile, physics-driven layer to the existing camera-based system—without requiring any new hardware.
🚨 Tesla has already implemented a new patent that improves the accuracy of the Auto Wiper system https://t.co/QjjKHKxSNv pic.twitter.com/mEbd04oJAu

Tesla drivers have griped about auto wipers since the company ditched traditional rain sensors in favor of Tesla Vision around 2018.
Owners routinely report the wipers failing to activate in light drizzle or mist, leaving windshields streaked and visibility dangerously reduced. Just as often, they formerly blasted into high-speed mode on dry, sunny days, screeching across glass and risking scratches or premature blade wear.
This is a rare occurrence anymore, but many owners still report the feature having the wipers perform at the incorrect speed or frequency when precipitation is falling.
Tesla has tried repeatedly to fix the problem through software alone.
Early “Deep Rain” initiatives and the 2023 Autowiper v4 update used multi-camera video and refined neural networks, with Elon Musk promising “super good” performance. The 2024.14 update added manual sensitivity boosts, and later FSD versions claimed further gains. Yet complaints persisted.
Elon Musk apologizes for Tesla’s quirky auto wipers, hints at improvements
Vision systems struggle with edge cases—glare, bugs, reflections, or faint mist—because they rely purely on visual inference rather than physical detection
The new patent takes a different approach. The car’s computer constantly measures electrical power delivered to the wiper motor. It subtracts predictable losses—internal motor friction, linkage drag, and aerodynamic resistance—leaving only the friction force between the rubber blade and windshield glass.
Water lubricates the glass, sharply reducing friction; dry or icy surfaces increase it dramatically. This real-time “tactile” data acts as an independent check on the camera’s visual cues, instantly shutting down false triggers on dry glass and fine-tuning speed for actual rain.
The system can also detect ice and auto-activate defrost heaters, while long-term friction trends alert drivers when blades need replacing.
By fusing vision with precise motor-load physics, Tesla has created a hybrid sensor that is both elegant and cost-free. Owners have waited years for reliable auto wipers; this OTA rollout may finally deliver them.

Tesla Roadster unveiling set for this month: what to expect
As Tesla finally edges toward production and an updated reveal, enthusiasts aren’t asking for compromises; they’re demanding the original vision be honored. Here are five clear expectations that will come with the vehicle’s unveiling, which is still set for later this month, hopefully.
The Tesla Roadster has been the ultimate carrot on a stick since its 2017 unveiling. Promised as the fastest production car ever made, with 0-60 mph in under two seconds and a top speed over 250 mph, it has endured years of delays.
As Tesla finally edges toward production and an updated reveal, enthusiasts aren’t asking for compromises; they’re demanding the original vision be honored. Here are five clear expectations that will come with the vehicle’s unveiling, which is still set for later this month, hopefully.
Performance and Safety Do Not Go Hand in Hand, and That’s the Point
The Roadster is not a family sedan or a daily commuter. It is a no-holds-barred supercar meant to embarrass six-figure exotics on track days. Tesla should resist the temptation to load it with every passive-safety nanny and electronic guardian that dulls the raw feedback drivers crave.
Owners want to feel the road, not be shielded from it. Strip away unnecessary electronic limits so the car can deliver the visceral thrill Elon Musk originally described. Safety ratings will still be strong because of Tesla’s structural excellence, but the Roadster’s mission is speed, not coddling.
He said late last year:
“This is not a…safety is not the main goal. If you buy a Ferrari, safety is not the number one goal. I say, if safety is your number one goal, do not buy the Roadster…We’ll aspire not to kill anyone in this car. It’ll be the best of the last of the human-driven cars. The best of the last.”
Musk was clear that this will not be a car that will be the safest in Tesla’s lineup, but that’s the point. It’s not made for anything other than pushing the limits.
Tesla Needs to Come Through on a HUGE Feature
The Roadster unveiling would be wildly disappointing if it were only capable of driving. Tesla has long teased the potential ability to float or hover, and they need to come through on something that is along those lines.
The SpaceX cold-gas thruster package was never a joke. Musk, at one time, explicitly said owners could opt for a set of thrusters capable of lifting the car off the ground for short hops or dramatic launches. That feature is what separates the Roadster from every other hypercar on the planet.
If the production version arrives without it—or with a watered-down “maybe later” version—enthusiasts will feel betrayed. Deliver the thrusters, make them functional, and let the Roadster literally hover above the competition.
An Updated Design Might Be Warranted
It’s been nine years since Tesla first rolled off the next-gen Roadster design and showed it to the world.
The 2017 concept still looks sharp, but eight years is an eternity in automotive styling. The sharp lines and aggressive stance now compete against the angular Cybertruck and the next-generation vehicles rolling out of Fremont and Austin.
Tesla Roadster patent hints at radical seat redesign ahead of reveal
A subtle refresh, maybe with sharper headlights, revised aero elements, and modern materials, would keep the Roadster feeling current without losing its identity. Fans don’t want a complete redesign, just enough evolution to prove Tesla still cares.
Self-Driving Isn’t a Necessity for the Tesla Roadster
Full Self-Driving hardware and software belong in the Model 3, Model Y, and the upcoming robotaxi—not in a two-seat rocket built for canyon carving. The Roadster’s entire appeal is the direct connection between driver, steering wheel, and asphalt.
Offering FSD as standard would dilute the purity that separates it from every other Tesla. Make autonomy an optional delete or simply omit it. Let the Roadster remain the purest driving machine in the lineup, because that’s what it is all about.
Tesla Needs to Come Through on the Unveiling Timeline
The last thing Tesla needs right now is another complaint about not hitting timelines or expectations. This unveiling has already been pushed back one time, from April 1 to “probably in late April.”
Repeated delays have tested even the most patient fans. Whatever date the company now sets for the next major reveal or start of production must be met. No more “next year” promises. The Roadster has waited long enough. When it finally arrives, it must feel worth every extra month.
If Tesla hits these five marks, the Roadster won’t just be another fast car—it will be the machine that redefines what a Tesla can be. The world is watching.

Tesla Cabin Camera gets an incredible new feature for added driver safety
The company quietly expanded the capabilities of its in-cabin camera with the rollout of Software Update 2026.8.6. Tesla hacker greentheonly revealed that coding for the software version provides details on now tracking the age of the driver.
Tesla’s interior Cabin-facing Camera just got a brand new feature that is an incredible addition, as it provides yet another layer of added safety.
The company quietly expanded the capabilities of its in-cabin camera with the rollout of Software Update 2026.8.6. Tesla hacker greentheonly revealed that coding for the software version provides details on now tracking the age of the driver.
The camera, which is positioned just above the rearview mirror, is now performing facial analysis to estimate the driver’s age. While not yet user-facing, the feature is the latest example of Tesla’s ongoing push to refine its driver monitoring system for both everyday safety and future Robotaxi operations.
Ha, interesting, cabin camera / driver monitor is now (2026.8.6) doing “driver age” checking.
I wonder if it’s going to filter out children or elderly too?
— green (@greentheonly) April 10, 2026
The cabin camera already processes images entirely onboard the vehicle for privacy, sharing data with Tesla only if owners enable it during safety-critical events.
Age estimation likely uses computer vision to classify facial features, similar to existing attention-tracking algorithms. Potential applications include preventing underage drivers from engaging Full Self-Driving (FSD) or shifting into drive, acting as a secondary safety lock.
It could also be linked to Robotaxi readiness: the upcoming Cybercab will need robust occupant verification to ensure children cannot hail or ride unsupervised.
In consumer vehicles, it could enable tailored FSD behaviors—more conservative acceleration and braking for elderly drivers, for instance—or simply block unauthorized use by minors.
Beyond age checks, the cabin camera powers Tesla’s comprehensive driver monitoring system, introduced years earlier and continuously improved. It first gained prominence for detecting inattentiveness. When Autopilot or FSD is active, the camera tracks eye gaze, head position, and steering inputs in real time.
If the driver looks away too long or fails to keep their hands ready, the system issues escalating visual and audible alerts before disengaging assistance. This has dramatically reduced misuse cases and helped Tesla meet stricter regulatory demands for hands-on supervision.
The camera also monitors for drowsiness. Activated above roughly 40 mph (65 km/h) after at least 10 minutes of manual driving, the Driver Drowsiness Warning analyzes facial cues—frequency of yawns and blinks—alongside driving patterns like lane drifting or erratic steering.
When fatigue is detected, a clear on-screen message and chime prompt the driver to pull over and rest, or even to activate Full Self-Driving. Tesla explicitly states this feature enhances active safety without relying on facial recognition for identity.
These layered capabilities create a robust safety net. Inattentiveness detection alone has curbed distracted driving during assisted operation. Drowsiness alerts address a leading cause of highway crashes by intervening before impairment escalates.
Adding age verification extends this protection: it could flag inexperienced young drivers for extra caution or restrict high-autonomy features, while preparing vehicles for a future where robotaxis must safely manage passengers of all ages.
With privacy safeguards intact and processing done locally, Tesla’s cabin camera continues evolving from a simple attention monitor into a sophisticated guardian—advancing safer roads today and autonomous mobility tomorrow.
