SpaceX, NASA finalize contract for second crewed Starship Moon landing
Around eight months after announcing its intention to do so, NASA has awarded SpaceX a contract for a second crewed Starship Moon landing as early as 2027.
Known as Option B, NASA has exercised a baked-in right to modify its Human Landing System (HLS) Option A contract with SpaceX – signed in April 2021 – to extract even more value from investments into the program. In addition to an uncrewed Starship Moon landing planned no earlier than (NET) 2024 and a crewed demonstration that could land two NASA astronauts on the Moon as early as 2025, NASA’s contract modification gives SpaceX the approval and resources it needs to prepare for a second crewed Starship Moon landing.
On top of securing NASA’s Artemis IV mission astronauts a ride to the lunar surface, the Option B contract will also allow SpaceX and NASA to pursue and demonstrate upgrades that will make Starship an even more capable and cost-effective Moon lander.
Update: NASA says that the Option B modification will cost $1.15 billion, raising the maximum value of SpaceX’s HLS contract to approximately $4.2 billion.
When NASA first announced its intention to add a second crewed Moon landing to SpaceX’s existing HLS contract, the agency couldn’t offer specific information about when that landing might occur or which Artemis mission it would be attached to. Part of the reason for that uncertainty was another announcement two months prior that NASA no longer expected a Moon landing to be paired with its Artemis IV (4) mission. And five days after a March 2022 announcement of plans for a second crewed Starship Moon landing, NASA seemingly reaffirmed that there would be a multi-year gap between Starship’s first crewed Moon landing (NET 2025; tied to Artemis III) and NASA’s second crewed Moon landing, which would use an unspecified lander.
But as of November 2022, NASA has thankfully abandoned plans to intentionally allow a gap between Moon landings. SpaceX’s Starship is now on contract to support back-to-back crewed Moon landings NET 2025 and 2027 as part of NASA’s Artemis III and Artemis IV missions. It’s unclear how or why NASA was able to make that change, but it’s a definite improvement over the alternative.

Additionally, NASA will work with SpaceX to debut new capabilities and improvements on Starship’s second crewed Moon landing. While the Artemis III landing will be about as barebones as possible, the Artemis IV Starship will be upgraded with the ability to transport more NASA astronauts (four instead of just two) and more cargo to the lunar surface. It’s not entirely clear, but NASA reportedly wants to land just ~180 kilograms (~400 lb) of cargo with the first crewed Starship, a vehicle likely capable of landing dozens of tons of cargo in addition to several astronauts. NASA hopes that future “sustainable” lander missions, a category that Starship’s Option B landing may or may not fall under, will transport up to one ton (~2200 lb) of cargo to and from the lunar surface.
Finally, the Artemis IV Starship will also be able to dock with NASA’s Lunar Gateway. Gateway is a small deep space station that will be located in a strange, high lunar orbit. It exists almost exclusively to give NASA’s Space Launch System (SLS) rocket and Orion crew capsule a destination they can both reach. The Orion capsule is almost twice as heavy as its Apollo counterpart and its European Service Module (ESM) offers less than half the performance of NASA’s retired Apollo Service Module. Combined, Orion is physically incapable of transporting itself (or astronauts) to the simpler low lunar orbits used by the Apollo Program.
Instead, NASA’s new Moon lander(s) have to pick up Orion’s slack. Starship will be responsible for picking up astronauts in a lunar near-rectilinear halo orbit (NRHO), transporting them to low lunar orbit, and returning them to NRHO in addition to landing on the Moon, spending a week on the surface, and launching back into lunar orbit.
Until it’s modestly upgraded in the late 2020s or 2030s, Gateway will be equally underwhelming. In fact, that’s part of the reason that Starship docking with the Gateway is in any way significant. SpaceX and NASA have decades of expertise docking and berthing spacecraft with space stations. But those spacecraft are typically smaller and lighter than the stations they were joining. Even after the Gateway is fully outfitted with a range of international modules, Starship will likely weigh several times more than the tiny station, making docking even more challenging than it already is.
Starship’s Moon lander variant could also have a cabin with hundreds of cubic meters of habitable space, while the Gateway is unlikely to ever have more than a few dozen. Having a Starship docked would thus immediately make the ultra-cramped station far more livable.
NASA says Artemis IV and the second crew Starship Moon landing will occur as early as 2027. But a ‘space prophet’ who predicted in 2017 that NASA’s SLS launch debut would slip from 2019 to “around 2023” and forecasted that SpaceX alone would win NASA’s Moon lander contract recently told Ars Technica’s Eric Berger that Artemis III, the mission before Artemis IV, is unlikely to launch before 2028. At the time, that source’s predictions verged on blasphemy, but they’ve ultimately proven to be eerily accurate. Only time will tell if their third ‘prophecy’ follows the same path.

Tesla has a Cybercab problem nobody saw coming
Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.
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
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:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

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
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 has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
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.
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.
