SpaceX and NASA accidentally set the stage for a new race to the Moon

Published

Almost entirely driven by chance, SpaceX and NASA may soon find themselves in an unintentional race to return humans to the Moon for the first time in half a century.

Both entities – SpaceX with its next-generation BFR and NASA with its Shuttle-derived SLS – are tentatively targeting 2023 for their similar circumlunar voyages, in which NASA astronauts and private individuals could theoretically travel around the Moon within just months of each other, showcasing two utterly dissimilar approaches to space exploration.

Over the course of no fewer than seven years of development, NASA’s SLS rocket and Orion spacecraft have run into an unrelenting barrage of issues, effectively delaying the system’s launch debut at a rate equivalent to or even faster than the passage of time itself. In other words, every month recently spent working on the vehicle seems to have reliably corresponded with at least an additional month of delays for the launch system.

Why these incessant delays continue to occur is an entire story in itself and demands the acknowledgment of some uncomfortable and inconvenient realities about the state of NASA’s human spaceflight program in the 21st century, but that is a story is for another time.

A different kind of paper rocket

Returning to SLS, a brief overview is in order to properly contextualize what exactly the rocket and spacecraft are and what exactly their development has cost up to now. SLS is comprised of four major hardware segments.

  • The Core Stage: A massive liquid hydrogen/liquid oxygen rocket booster, this section is essentially a lengthened version of the retired Space Shuttle’s familiar orange propellant tank, while the stage’s four engines are quite literally taken from stores of mothballed Space Shuttle hardware and will be ingloriously expended after each launch (SLS is 100% expendable).
  • Solid Rocket Boosters (SRBs): Minimally modified copies of the SRBs used during the Space Shuttle program, SLS’ SRBs have slightly more solid propellant and have had all hints of reusability removed, whereas Space Shuttle boosters deployed parachutes and were reused after landing in the Atlantic Ocean.

  • The Upper Stage (Interim Cryogenic Propulsion System, ICPS): ICPS is a slightly modified version of ULA’s off-the-shelf Delta IV upper stage.
  • The Orion spacecraft and European Service Module: Borrowing heavily from the Apollo Command and Service Modules that took humanity to the Moon in the 1960s and 70s, Orion has been in funded development in one form or another for more than 12 years, with just one partial flight-test to call its own. Orion’s development has cost the U.S. approximately $16 billion since 2006, with another $4-6 billion expected between now and 2023, a sum that doesn’t account for the costs of production and operations once development is complete.

 

For the SLS core stage and SRBs, a generous bottom-rung estimate indicates that $14 billion has been spent on the rocket itself between 2011 and 2018, not including many billions more spent refurbishing and modifying the rocket’s aging Saturn and Shuttle-derived launch infrastructure at Kennedy Space Center. Of the many distressing patterns that appear in the above descriptions of SLS hardware, most notable is a near-obsessive dependence upon “heritage” hardware that has already been designed and tested – in some cases even manufactured.

Despite cobbling together or reusing as many mature components, facilities, and workforces as possible and relying on slightly-modified commercial hardware at every turn, SLS and Orion will somehow end up costing the United States more than $30 billion dollars before it has completed a single full launch; potentially rising beyond $40 billion by the time the system is ready to launch NASA astronauts.

Moonward bound

SLS’ first crewed mission, known as Exploratory Mission-2 (EM-2), brings us to the title – NASA’s mission planning has settled on sending a crew of four astronauts on what is known as a Free Lunar Return trajectory in the Orion spacecraft, essentially a single flyby of the Moon. Official NASA statements appear to be sending mixed messages on the schedule for EM-2’s launch, with September 2018 presentations indicating 2022 while a late-August blog post suggests that the crewed circumlunar mission is targeting launch in 2023.

As it happens, SpaceX announced its own plans for a (private) crewed circumlunar voyage less than two weeks ago. Funded in large part by Japanese billionaire Yasuka Maezawa, SpaceX’s hopes to send 10+ people to the Moon on its next-generation BFR launch vehicle, comprised of a fully-reusable booster and spaceship. Deemed Dear Moon by Maezawa, SpaceX is targeting an extremely ambitious launch deadline sometime in 2023, although CEO Elon Musk frankly noted that hitting that 2023 window would require all aspects of BFR booster and spaceship development to proceed flawlessly over the next several years.

Compared to the 10+ years and $30+ billion of development SLS and Orion will have taken before their first full launch, SpaceX is targeting the first orbital BFR test flights as early as 2020 or 2021, self-admittedly optimistic deadlines that will likely slip. Still, betting against SpaceX completing its first BFR launch sometime in the early to mid-2020s for something approximating Musk’s $2-10 billion development cost seems a risky move in the context of SpaceX’s undeniable track record of proving the old-guard wrong.

 

It must be noted that the apparent alignment of both SpaceX and NASA’s first crewed circumlunar missions with new rockets and spacecraft is a fluke of chance, and the fact that it may or may not take the shape of a second race to the Moon – pitting two dramatically different ideologies and organizational approaches against each other – is purely coincidental.

However, despite the undeniable fact that NASA and SpaceX are deeply and cooperatively involved through Crew and Cargo Dragon and despite Musk’s genuine affirmations of support and admiration for the space agency, it can be almost guaranteed that the world will look on in the 2020s with the same underlying emotions and motivations that were globally present during the Apollo Program. Rather than a battle of economic and nationalistic ideologies, the New Space Race of the 2020s will pit two (publicly) amicable private and public entities against each other at the same time as they work hand-in-hand to deliver crew and cargo to the International Space Station.

Critically, this new “race” will be fairly illusory. Thanks to the fact that the new goal of human spaceflight appears to be the sustainable exploration of the solar system, there will inherently be no Apollo-style finish line for any one company or country or agency to cross. Rather than the Apollo Program’s shortsighted economic motivations and its consequentially abrupt demise, the end-result of this new age of competition will be the establishment of humanity as a (deep) spacefaring species, be it a temporary burst of effort or a permanent human condition.

Tesla has a Cybercab problem nobody saw coming

Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.

Published

Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”

Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.

The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.

Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.

The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.

The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.

Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”

How SpaceX Is raising Raptor’s sea-level thrust while holding engine mass steady

Published

on

Credit: SpaceX

SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.

Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.

This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.

This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.

Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.

Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.

The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.

Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.

For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.

Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.

Tesla Assisted Driving expands to tenth EU country

Published

on

Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.

Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.

The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.

Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.

In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.

Tesla starts showing how FSD will change lives in Europe

The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.

The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.

These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.

However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
