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 The now-outdated 2018 design also featured almost 90 cubic meters of unpressurized cargo space, a bet less than nine times as much SpaceX’s operational Cargo Dragon spacecraft.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.

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 Cybertruck gets a big price change on two of its three trims

Published

on

Credit: Tesla

Tesla Cybertruck trims saw a big price change, at least on two of the three available to consumers, as demand for the all-electric pickup appears to be increasing.

Tesla bumped up its Base All-Wheel-Drive trim level up to $74,990 from $69,990 and the Premium All-Wheel-Drive configuration from $79,990 to $84,990. The Cyberbeast price remains unchanged at $99,990.

Despite questions of demand for the truck, Tesla is bumping its two least expensive trims up $5,000 to signal that there are plenty of buyers. Although SpaceX has been buying Tesla Cybertruck units to utilize as company vehicles, it is no secret that the Cybertruck is among the most sought-after Tesla models out there.

The issue has always been pricing, at least for the most part. When Tesla initially launched the Cybertruck AWD at $59,990 a few months back, the company stated that price would remain intact for just ten days due to the influx of orders it received.

Cybertruck Sales: Is It the Product or Pricing?

Depending on who you ask, you will likely hear one of two explanations for relatively low Cybertruck sales: either the product itself or the pricing.

Yes, this is the best-selling all-electric pickup on the market. However, there are people who simply hate the look of it, which I understand, but do not agree with. Look is totally subjective, and I love the look of the Cybertruck.

Some people will not buy the Cybertruck because of the look, but I am under the impression that sales would be much better if this truck were priced lower; something that might not be possible considering Tesla’s need to make money on its products. When it was unveiled in 2019, its most expensive trim level was $69,990. Now, the cheapest trim level is more expensive than that.

I would be in a Cybertruck if it were more affordable. I LOVE my Model Y, but Cybertruck is the best vehicle Tesla makes, and it’s not particularly close. Even in the base model, the steer-by-wire, the space, storage, and performance make it more desirable than the Model Y to me. I cannot be the only Tesla owner without a Cybertruck who feels this way.

Tesla Semi factory is getting a celebration nobody expected

Tesla will inaugurate its Nevada Semi factory September 24, five months after production quietly began ramping.

Published

By

Tesla says it will officially inaugurate its new Semi factory in Nevada next month. The Tesla Semi account posted the announcement on X, sharing a graphic titled “Semi Rollout” with a date of September 24. No further details were given about the format of the event or who would attend.

While Tesla’s dedicated Semi plant in Sparks, adjacent to Gigafactory Nevada, opened back in April, with the first trucks rolling off the high volume line on April 29, the timing for the factory inauguration comes at a surprise. The ribbon cutting event five months into production is a break from how Tesla has usually handled its other factories, where the first truck or car off the line typically served as the milestone moment.

The 1.7 million square foot factory was built as part of a $3.6 billion expansion Tesla announced in early 2023, and it shares a site with the battery cell lines that feed the Semi’s structural pack, a decision meant to remove the supply bottleneck that delayed the truck for years. The plant is designed for 50,000 trucks a year at full ramp. Semi program director Dan Priestley has said production “is now ramping” rather than claiming it has reached scale.

Nine years passed between the Semi’s 2017 unveiling and this stage of production, with the truck slipping from an original 2019 target through hand built pilot units for PepsiCo and a slow build out of the Nevada plant. An inauguration event now gives Tesla a stage to talk up that ramp and reset expectations for how many trucks it can begin delivering at scale.

The September date also lines up with the Semi’s next milestone. Tesla confirmed the truck is heading to Europe with a full unveiling at the IAA Transportation trade show in Hannover, Germany, running September 15 through 20. Between the Nevada event and the Hannover reveal, Tesla has roughly a week and a half in September to make the case that the Semi is now a truck being built and sold on two continents rather than tested in a handful of fleets.

Elon Musk just set a condition that could end Falcon 9 as we know it

Elon Musk says SpaceX will finally retire Falcon 9 once Starship flies reliably every week.

Published

Elon Musk gave the clearest timeline yet for retiring Falcon 9, SpaceX’s workhorse rocket.

The comment came in a reply on X, where Musk wrote that “once Starship is flying reliably several times per week, it makes sense to shift super scarce SpaceX engineering and production resources to Starship to get launch rate to several times per day, which means winding down Falcon.” He was responding to physicist Casey Handmer, who noted that NASA is reportedly uneasy about SpaceX phasing out Falcon after building what Handmer called the most successful launcher ever, with the fleet nearing 1,000 total launches.


Falcon 9 is still SpaceX’s busiest vehicle by far. The company is on pace for roughly 140 to 145 Falcon flights this year, following 165 in 2025, president Gwynne Shotwell told Time earlier in 2026. She has already said Falcon flights would “tail off” as Starship comes online, while reports indicate that SpaceX has stopped booking new Falcon 9 launches past 2028 and halted production of some expendable Falcon hardware, according to Bloomberg.

It’s worth noting that Musk’s post is a condition, and not a countdown on when Falcon will retire. Starship has not yet flown weekly, let alone daily. Its most recent flight in July ended with a soft splashdown in the Indian Ocean, a milestone Musk pointed to earlier this month when he said the vehicle’s heat shield problem was effectively solved. SpaceX towed that ship to Christmas Island for inspection, and the next flight, Flight 14, is aimed at putting Starship into orbit for the first time. A tower catch attempt for the upper stage has been pushed back to what Musk has called “a few months” away.

SpaceX and a new Trump order that could rewrite the next decade of launches

The gap between Falcon’s role today and Starship’s promised role tomorrow matters most to NASA. Falcon and its Dragon capsule remain the only way the agency rotates astronauts to and from the International Space Station, and Starship is not certified to carry NASA crews. Musk’s post did not address how that handoff would work if Falcon winds down before a crew-rated Starship variant exists. The timing lines up with Musk’s other recent Starship comments. Two days before the Falcon post, he told a different X user that SpaceX is aiming for more than 30 Starship launches a day by 2030, or roughly 10,000 a year, a figure tied to the Trump administration’s new push for higher national launch cadence. Falcon, which took over a decade to reach its first 100 launches, was never built to approach that kind of volume.

For now, Falcon 9 keeps flying at a near-record pace while Starship works to prove it can do the job Musk has already picked out for it.
