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 The now-outdated 2018 design also featured almost 90 cubic meters of unpressurized cargo space, a bet less than nine times as much SpaceX’s operational Cargo Dragon spacecraft.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 has continued to flex the strength, rigidity, and robustness of its all-electric pickup, the Cybertruck. In fact, since 2019, Cybertruck’s ability to avoid dents, dings, and even gunfire has been one of the main selling points Tesla has used to attract buyers who are looking for a vehicle that can handle the most intense challenges.
But that does not mean Tesla is not still actively trying to make it even better.
In a new hardware update, Tesla has decided to change the material of the Cybertruck’s underbody panels from aluminum to carbon fiber, a move that aims to not only increase pricing efficiency but also improve strength.
RELATED:
Cybertruck Lead Engineer Wes Morrill confirmed the change was made to the Cybertruck recently after it was spotted by Coleton Guerin of Out of Spec. This particular trim level was a Cyberbeast, but it is being applied to all trims to keep supply chain efficiency high and have less variance across trim levels.
Morrill said that Tesla tested different materials for the underbody panel protection, and carbon fiber performed better than aluminum, which is what the company was using since its first deliveries in 2023.
Additionally, there are some efficiency improvements because Tesla can better form the areas around the bolts to keep underbody airflow cleaner than previously.
good eye – it’s a new material. Testing showed it to be more durable than the aluminum while being lower weight and cost. Also slight efficiency improvement since we can better form the areas around the bolts to keep the underbody airflow cleaner than what stamped aluminum allows
— Wes (@wmorrill3) July 30, 2026
Carbon fiber is traditionally lighter and more durable than aluminum, which is why it is such a popular material among luxury automakers, and EV makers will utilize some of the materials around battery packs to save weight.
This is the first instance of Tesla utilizing carbon fiber on the Cybertruck’s exterior to help with overall performance and strength. As previously mentioned, Tesla used aluminum to protect the underside of the body, but it is pretty typical for the company to continue making engineering changes that will improve the car in the future.
Tesla released Full Self-Driving version 14.3.7 yesterday, and after about 90 miles of testing today, it is evident there are some definite fixes from version 14.3.6, which I wrote about last week and called a regression.
Within the first 40 minutes of my drive on v14.3.7, it saved me from getting into an accident with an unaware Dodge Charger driver, and some of the things Tesla seemed to miss in v14.3.6 were definitely improved. All in all, the release so far has some really great performance, and I’m looking forward to testing it further.
For now, here’s everything I noticed with v14.3.7:
Overall Improvement
Just generally speaking from a ride perspective, this was a really great experience. A lot of the hesitancy I experienced on v14.3.6 was gone. There were no instances of brake-stabbing, wheel-jerking, or any uncertain or unconfident movements. It was void of anything that I felt made it timid with v14.3.6.
The one thing I do hope to see down the road is a smaller need to adjust Speed Profiles so often. Because Tesla calls FSD “Supervised,” I’m okay with needing to hit the scroll wheel a few times a drive.
However, I hope that things can be incrementally improved upon with speed. Sometimes it’s too fast; other times it’s too slow. It’s a difficult thing to hone in and refine, but I hope it eventually gets there.
I didn’t notice any significant left lane camping or any behaviors that were completely out of line. I am hopeful that this opinion does not change, but after driving a few days with this version and putting it in a variety of different situations, you are exposed to more behaviors, some of which are not necessarily what I’d prefer.
The big things to notice, at least in my experience thus far, are that the major issues with previous versions — meaning the braking stabbing and wheel jerking — simply weren’t there. That’s enough to already consider this progress compared to .6.
Manual Signal Override is More Responsive
On .6, I had quite a few issues with FSD ignoring my manually input turn signals. If Tesla wants to call it “Supervised,” then the car should not ignore any input the driver gives. If I touch the accelerator on FSD, the car speeds up.

The car did a great job of obeying my turn signals when I wanted it to change lanes, which is welcome.
Parking Lot Performance
Before .6, I traditionally took over in nearly every parking lot my car entered, because I knew it would not park somewhere that I wanted, and usually, it was just a tad too timid in this setting.
The one bright spot of .6 was how well it handled parking lots. This continued with v14.3.7:
I’m always really happy to see progress at all, but once parking preferences come to FSD, as long as this performance is still around, that could potentially be the biggest improvement I’ve seen in FSD in the year I’ve been using it personally on a daily basis.
Full Self-Driving Averts Disaster
A Dodge Charger changed into my lane without checking if I was there, running me off the road. FSD made the initial avoidance maneuver; I grabbed the wheel out of instinct, looked in my side mirror to ensure I had nobody following closely behind, hit the brake, and straightened the car back up to avoid a curb:
🚨 Guys this is why you all NEED to stay vigilant behind the wheel, even on Tesla Full Self-Driving
Human drivers are UNHINGED and have no idea what they’re doing anymore. This was a kid obviously younger than 20 years old with zero awareness.

There have been quite a few responses to this video stating that I should never have grabbed the wheel. To be honest, I really wish I had not done so, because I do believe FSD would have avoided any sort of collision with anything, including the car or the curb.
However, this was the first time I had ever been this close to being hit while using FSD. My natural reaction was to take over. I think if I had had something like this happen before, my reaction might have been different.
Hitting the brake avoided hitting the curb, while FSD swerved to avoid the car. My concern after the car was clear of my front end was the curb. All in all, I’m really happy with how things turned out, and I think anyone could be a critic of how I handled it. I only had a split second to really make a decision, and thankfully, any damage was avoided.
It is clear FSD managed to avoid the car coming down before I was able to. I truly credit FSD for avoiding the collision.
What Needs to Improve
Better Recognition of Potholes, Uneven Roads, Sharp Changes in Roadway/Bumps
On Friday, my Fianceè and I were in the car, and FSD was driving us. We crossed over a roadway that has a traffic light, and FSD was traveling at 40 MPH on Standard, 5 MPH over the speed limit. Everything was more than reasonable.
However, the road we were crossing at the light has a major bump both as you start and finish crossing it. Without a speed reduction, your car can go airborne. The Tesla did just this on Friday on v14.3.6; it was an uncomfortable bounce that pretty much confirmed I would not ever let FSD go over again unless we were sitting at that intersection when there is a red light.
I even tried scrolling down into Sloth quickly, but I ended up just taking over:
This is that big bounce that I mentioned in the quoted post.
It’s just a tad too drastic to take at the speed FSD wants to go over it. You can see me quickly swipe down into Sloth, but I intervened. https://t.co/K20PK9ysBg pic.twitter.com/81Oc82ZJcZ

A few people have said it remains related to the vision-based approach and its difficulty comprehending 3D. This is a huge issue because this can cause serious damage at certain speeds.
Navigation
Nothing new here. I still turn off “Online Routing” quite frequently to get the car to take logical routes from time to time.
Auto Wipers
Auto Wipers are just plain bad. I really hope Tesla just uses a rain sensor. I thought they had improved at one point, but I still get dry wipes, Speed 4 on a drizzle, and Speed 2 on a steady rain. In reality, these should be switched.

SpaceX will report second quarter results after the market closes on Tuesday, August 4, marking the first time the company has opened its books to the public since its record IPO in June. Management will host a live audio only webcast at 4:30 p.m. ET, streamed on X, with no dial in option.
The debut carries more weight than a typical first quarter as a public company. Two trading days after the release, on August 6, the first tranche of SpaceX’s lockup expires, freeing roughly 911.5 million insider and employee shares, worth well over $100 billion at current prices and the largest such release in Wall Street history. A second, larger tranche tied to the stock trading 30 percent above its $135 IPO price never triggered, since shares have spent most of July trading below that price.
Wall Street’s models point to revenue near $6.9 billion for the quarter, up sharply from the $4.69 billion SpaceX reported in the first quarter, with a narrower per share loss than the $1.27 posted three months earlier, according to estimates compiled by Motley Fool. Those numbers will be the first look at how SpaceX’s three segments, Starlink, launch and AI, are performing independently.
SpaceX scores another massive Pentagon deal to support military satellites
Investors heading into the call have a specific list of questions. How many net new Starlink subscribers did SpaceX add after ending March with 10.3 million, and is average revenue per user holding up as the service expands into lower income markets. How much of the AI segment’s revenue reflects contract signings with Anthropic, Google and Reflection AI this year, deals that combined could annualize to nearly $28 billion if fully ramped. Whether capital expenditures, which nearly doubled in the AI segment alone between 2024 and 2025, are still accelerating or starting to plateau. And whether management offers any forward guidance at all, something SpaceX has never done publicly.
The report will also land days after Elon Musk publicly denied a Wall Street Journal report describing internal planning to separate Tesla’s China business ahead of a potential Tesla-SpaceX merger. Whether Musk or SpaceX executives address that speculation on the call, even indirectly, maybe something investors will be listening for on Tuesday.
As Teslarati reported after Musk’s own warning to short sellers last week, the CEO has made clear he expects skeptics to be proven wrong over time. Tuesday will be the first chance for the numbers themselves to make that case.
