Ex-SpaceX engine expert to help design rockets built for launch on world’s largest jet
Stratolaunch, an aerospace company funded by Microsoft-made billionaire Paul Allen to build the world’s largest flightworthy aircraft, has announced a decision to build its own liquid-fueled rockets, to be air-launched from the aforementioned mega-plane.
Targeting an inaugural launch of the first version of the rocket – currently nicknamed “Kraken” – as early as 2022, Stratolaunch has chosen Jeff Thornburg, formerly SpaceX’s Vice President of Propulsion Engineering and the father of the company’s Mars-focused Raptor engine, to lead its foray into in-house rocket propulsion development and manufacturing.

But first: building the world’s largest aircraft
Stratolaunch’s first task at hand, however, is to begin flight-testing the largest (hopefully) operational aircraft in history, a prerequisite for the company’s longer-term orbital rocket and spaceplane aspirations. Nicknamed “Roc” after a mythical (and fictional) bird so large it could carry an elephant, the plane certainly lives up to its namesake. Featuring a full six of the same engines that power Boeing’s once-record-breaking 747 airliner and a wingspan that could easily fit three smaller 737 airliners with room to spare, it is genuinely difficult (if not impossible) to successfully convey the sheer scale of Roc outside of witnessing it in person.
Stationed in California’s Mojave Desert, the aircraft’s one and only copy is, for the most part, completed and has spent the brunt of 2018 conducting runway taxi tests, hopefully culminating in an inaugural flight test later this year or early next year. Designed to lift orbital-class rockets weighing as much as 250 metric tons (550,000 lb) to an altitude of at least 9100 meters (30,000 feet), the primary benefit of using aircraft as launch platforms derives from the simple fact that the atmospheric density at 30,000 feet is more than three times less than that at sea level. Similar to aircraft, rocket performance dramatically improves as atmospheric density decreases: less atmosphere means lower drag and pressure.
Rockets that launch from sea-level have to grapple with the difficulties of Earth’s relatively thick atmosphere at that height, with major launch events like “Max-Q” being big concerns almost solely because the dense air exerts major forces on launch vehicles and demands extreme measures like throttling down booster engines (very inefficient) and optimizing structures for aerodynamic efficiency despite the fact that rockets spend very little time operating in a significant atmosphere.
A launch pad without a rocket (sort of)
However, the simple fact of the matter is that billionaire Paul Allen’s colossal aircraft essentially does not have a single air-launched rocket in the world that can properly take advantage of its capabilities. Originally sized and designed with an air-launched version of SpaceX’s Falcon 9 in mind, that relationship folded amicably after roughly a year (2012), at which point SpaceX realized it would need to almost completely redesign a unique variant of Falcon 9. Your author will readily admit that they have admired the insanity of such a massive plane while still severely doubting its practical utility.
Thankfully, it appears that Allen is adamantly opposed to the idea that Stratolaunch is some silly whim to build the world’s largest plane. Rather, he is exceptionally reserved and pragmatic when discussing the aerial launch platform, according to a recent and extensive interview by Wired Magazine’s Steven Levy.
“Allen isn’t one to show exuberance, and when he speaks about the plane he focuses on its future utility. ‘When you see that giant plane, it’s a little nutty,’ he says. ‘And you don’t build it unless you’re very serious, not only about wanting to see the plane fly but to see it fulfill its purpose. Which is getting vehicles in orbit.’ – Paul Allen, 2018

Currently, Orbital ATK’s (now Northrop Grumman Innovation Systems) air-launched Pegasus XL rocket is the only “customer” in the world that can realistically use Stratolaunch as a launch platform, not exactly an impressive or sustainable launch vehicle with a maximum performance of less than 450 kg (~1000 lbs) to low Earth orbit for an incredible ~$40 million per (expendable) flight.
To answer that call and ensure Stratolaunch’s utility, the company reportedly began seriously considering its own in-house expendable and reusable rockets and propulsion systems sometime in 2016, plans that have since grown concrete and been publicly embedded into Stratolaunch’s overarching mission. Nicknamed “Kraken” after the mythical sea monster, the company hopes to develop an initially expendable rocket system capable of launching 3400 – 6000 kg (~7500 – 13250 lbs) into low Earth orbit with single booster and triple booster variants. Further down the line, Stratolaunch is eyeing the design and production of a fully and rapidly reusable orbital spaceplane, potentially including a version that would carry astronauts into space.

Normally, one might simply roll their eyes at yet another startup touting small(ish) expendable rockets with first launches no earlier than the early 2020s – the market is getting to be absurdly and impossibly overcrowded at this point. However, Stratolaunch differs for one fundamental and reason: they have placed ex-SpaceX propulsion executive and expert Jeff Thornburg at the helm of the company’s freshly public rocket propulsion wing. While at SpaceX, Mr. Thornburg spent all but one of his five years with the company (2011-2015) single-mindedly focused on the development and engineering of all aspects of the Raptor rocket engine, a next-generation propulsion system designed to enable SpaceX’s sustainable colonization of Mars.
Raptor is an exceptional rocket engine thanks in no small part to Thornburg’s brilliance as a propulsion engineer, and that same brilliance and half-decade of experience at the most successful rocket startup in existence could ultimately prove a massive boon for Stratolaunch’s otherwise interesting but unexceptional expendable rocket concepts.
Put simply, under Jeff Thornburg’s direction and with access to founder Paul Allen’s considerable wealth, Stratolaunch is undoubtedly worth keeping a close eye in the future, both far and near.

Ferrari, the Italian supercar maker, has revealed the name, interior, and interface design of its first-ever electric vehicle project, the Luce, initiating a new chapter in the rich history of the company’s automotive books.
This is the first time Ferrari has revealed such intimate details regarding its introductory EV offering, which has been in the realm of possibility for several years.
As more companies continue to take on EV projects, and some recede from them, supercar companies like Ferrari and Lamborghini are preparing to offer electric powertrains, offering super-fast performance and a new era of speed and acceleration.
Luce – a New Chapter in Ferrari
The company said that the name Luce is “more than a name. It is a vision.” Instead of looking at its first EV offering as a means to enter a new era of design, engineering, and imagination. The company did not want to compromise any of its reputation, high standards, or performance with this new project. It sees it as simply a page turn, and not the closing of a book:
“This new naming strategy reflects how the Ferrari Luce marks a significant addition to the Prancing Horse’s line-up, embodying the seamless expression of tradition and innovation. With its cutting-edge technology, unique design, and best-in-class driving thrills, it unites Ferrari’s racing heritage, the timeless spirit of its sports cars, and the evolving reality of contemporary lifestyles. It testifies to Ferrari’s determination to go beyond expectations: to imagine the future, and to dare. Because leading means illuminating the path ahead – and Luce embodies that mindset.”
Ferrari Luce Design
Ferrari collaborated with LoveFrom, a creative collective founded by Sir Jony Ive and Marc Newson. The pair has been working with Ferrari for five years on the Luce design; everything from materials, ergonomics, interface, and user experience has been designed by the two entities.
The big focus with the interior was to offer “a first, tangible insight into the design philosophy…where innovation meets craftsmanship and cutting-edge design. The team focused on perfecting and refining every solution to its purest form — not to reinvent what already works, but to create a new, carefully considered expression of Ferrari.”

The company also said:
“Ultimately, the design of the Ferrari Luce’s interior is a synthesis of meticulous craftsmanship, respect for tradition, and thoughtful innovation. It offers a new choice for Ferrari enthusiasts – one that honours the past while embracing the future, and exemplifies the brand’s enduring commitment to quality, performance, and cultural significance.”
The appearance of the elements that make up the interior are both an ode to past designs, like the steering wheel, which is a reinterpretation of the iconic 1950s and 1960s wooden three-spoke Nardi wheel, and fresh, new designs, which aim to show the innovation Ferrari is adopting with this new project.
Interior Highlights
Steering Wheel
The Ferrari Luce is a shout-out to the Nardi wheel from the 1950s and 60s. It is constructed of 100% recycled aluminum, and the alloy was developed specifically for the vehicle to “ensure mechanical resistance and a superb surface quality for the anodisation process.”
It weighs 400 grams less than a standard Ferrari steering wheel:

It features two analogue control modules, ensuring both functionality and clarity, Ferrari said. The carmaker drew inspiration from Formula One single-seaters, and every button has been developed to provide “the most harmonious combination of mechanical and acoustic feedback based on more than 20 evaluation tests with Ferrari test drivers.”
Instrument Cluster and Displays
There are three displays in the Luce — a driver binnacle, control panel, and rear control panel, which have all been “meticulously designed for clarity and purpose.”
The binnacle moves with the steering wheel and is optimized for the driver’s view of the instrumentation and supporting driver performance.

Displays are crafted by Samsung and were specifically designed for the car, using a “world first – three large cutouts strategically reveal the information generated by a second display behind the top panel, creating a fascinating visual depth that captures the eye.”
Samsung Display engineers created an ultra-light, ultra-thin OLED panel for the vehicle.

Pricing is still what remains a mystery within the Luce project. Past reports have speculated that the price could be at least €500,000, or $535,000.

Elon Musk pivots SpaceX plans to Moon base before Mars
The shift, Musk explained, is driven by launch cadence and the urgency of securing humanity’s long-term survival beyond Earth, among others.
Elon Musk has clarified that SpaceX is prioritizing the Moon over Mars as the fastest path to establishing a self-growing off-world civilization.
The shift, Musk explained, is driven by launch cadence and the urgency of securing humanity’s long-term survival beyond Earth, among others.
Why the Moon is now SpaceX’s priority
In a series of posts on X, Elon Musk stated that SpaceX is focusing on building a self-growing city on the Moon because it can be achieved significantly faster than a comparable settlement on Mars. As per Musk, a Moon city could possibly be completed in under 10 years, while a similar settlement on Mars would likely require more than 20.
“For those unaware, SpaceX has already shifted focus to building a self-growing city on the Moon, as we can potentially achieve that in less than 10 years, whereas Mars would take 20+ years. The mission of SpaceX remains the same: extend consciousness and life as we know it to the stars,” Musk wrote in a post on X.
Musk highlighted that launch windows to Mars only open roughly every 26 months, with a six-month transit time, whereas missions to the Moon can launch approximately every 10 days and arrive in about two days. That difference, Musk stated, allows SpaceX to iterate far more rapidly on infrastructure, logistics, and survival systems.
“The critical path to a self-growing Moon city is faster,” Musk noted in a follow-up post.
Mars still matters, but runs in parallel
Despite the pivot to the Moon, Musk stressed that SpaceX has not abandoned Mars. Instead, Mars development is expected to begin in about five to seven years and proceed alongside the company’s lunar efforts.
Musk explained that SpaceX would continue launching directly from Earth to Mars when possible, rather than routing missions through the Moon, citing limited fuel availability on the lunar surface. The Moon’s role, he stated, is not as a staging point for Mars, but as the fastest achievable location for a self-sustaining off-world civilization.
“The Moon would establish a foothold beyond Earth quickly, to protect life against risk of a natural or manmade disaster on Earth,” Musk wrote.

Musk confirms Tesla Semi production ramp
Tesla CEO Elon Musk reaffirmed on X that the Semi is finally moving into volume production, posting on Sunday that “Tesla Semi starts high volume production this year.”
The update comes as Tesla refreshed its Semi lineup on its official website, an apparent hint that the program is transitioning from limited pilots into wider commercial deployment. As per Tesla’s official website, two variants of the Semi will be offered to consumers: Standard and Long Range.
The Standard trim offers up to 325 miles of range with an energy consumption rating of 1.7 kWh per mile and a gross combination weight rating of 82,000 pounds. The Long Range version pushes driving range to 500 miles, with Tesla noting a higher curb weight of about 23,000 pounds, likely due to a larger battery pack.
Both trims support fast charging, with Tesla stating that the Semi can recover up to 60% of its range in 30 minutes using compatible charging infrastructure.
Broader Tesla Semi rollout
Tesla has already delivered production Semi units to select partners, including snack and beverage giant PepsiCo as well as logistics behemoth DHL, which confirmed that its truck operates daily in California, traveling roughly 100 miles per day and requiring charging just about once a week.
The company has also partnered with Uber Freight, as noted in a Benzinga report, with Tesla executives previously describing the agreement as a way for fleet operators to experience the Semi’s lower operating and maintenance costs firsthand.
With Musk now publicly committing to high-volume production, the Semi appears poised to move beyond pilot programs and into scaled commercial use, an important step in Tesla’s wider push to electrify heavy-duty and long-range trucking.
