SpaceX launches Japanese lander, NASA cubesat to the Moon
A SpaceX Falcon 9 rocket has successfully launched a privately-developed Japanese Moon lander and a NASA Jet Propulsion Laboratory cubesat on their way to lunar orbit.
Following five back-to-back delays that pushed the launch from November to mid-December, Falcon 9 lifted off with Japanese startup ispace’s first HAKUTO-R Moon lander on December 11th, kicking off a multi-month journey that will take the spacecraft more than 700,000 miles (1.1M km) away from Earth. It’s not the first time SpaceX has launched a mostly commercial Moon lander, and it won’t be the last. SpaceX’s first Moon lander launch happened in February 2019, when Falcon 9 launched Israeli company SpaceIL’s Beresheet Moon lander as a rideshare payload on Indonesia’s PSN-6 geostationary communications satellite. Beresheet failed just a minute or two before touchdown, but the attempt was still a historic step for commercial spaceflight.
Just shy of three years later, SpaceX has launched another private Moon lander. Unlike Beresheet, which made its way to the Moon from geostationary transfer orbit (GTO), HAKUTO-R was Falcon 9’s main payload, allowing the rocket to launch it directly into deep space. A Jet Propulsion Laboratory (JPL) cubesat that missed a long-planned ride on NASA’s first Space Launch System (SLS) rocket also joined the Moon lander as a Falcon 9 rideshare payload.

Approximately four months from now, both spacecraft will reach the end of similar low-energy ballistic transfer trajectories, at which point they will have limited opportunities to enter lunar orbit and continue their missions. Reaching that checkpoint will require several successful orbital correction maneuvers and enough longevity to survive months in deep space, unprotected by Earth’s magnetic fields.
If they make it that far, HAKUTO-R will conduct several more burns to reach low lunar orbit (LLO), where ispace will verify the spacecraft’s health and eventually attempt a soft landing on the Moon. A privately-developed spacecraft has never landed on an extraterrestrial body, so the prestige at stake is about as high as it can get. If JPL’s Lunar Flashlight spacecraft [PDF] survives its journey, it will enter a near-rectilinear halo orbit around a point of gravitational equilibrium (Lagrange point) between the Earth and Moon. Once on station, it will spend most of its time 9000 kilometers (~5600 mi) away from the Moon but occasionally fly within 15 kilometers (~9 mi) of the surface. Under JPL’s nominal mission plan, Lunar Flashlight will complete at least ten week-long orbits and use an infrared laser instrument to search for water ice in permanently-shadowed Moon craters during each close approach.
Without context, both missions seem to complement each other well, and it’s not hard to imagine an alternative scenario where a cubesat like Lunar Flashlight was intentionally included to prospect for ice that a lander could then target. But the JPL cubesat’s presence on ispace’s HAKUTO-R was purely by accident. Because of certain design decisions made by NASA’s Space Launch System (SLS) rocket and Orion spacecraft contractors, the giant rocket is intended to launch cubesat rideshare payloads to the Moon, but those satellites are barely accessible for the entire time the rocket is configured for its unprecedentedly slow launch campaigns.
As a result, even though SLS lifted off for the first time in November 2022, its cubesat payloads had to be ready for launch and installed on the rocket in October 2021. Out of 14 planned payloads, four – including Lunar Flashlight – weren’t ready in time, forcing them to find other ways to deep space. Ironically, that may have been an unexpected blessing, as the ten payloads that did make the deadline wound up sitting inside SLS for 13 months, much of which was spent at the launch pad. Half of those satellites appear to have partially or completely failed shortly after launch.
Because of the extremely circuitous path the NASA rocket ultimately took to reach launch readiness, JPL was able to find a new ride to the Moon and launch less than one month after SLS and its co-passengers. Unlike those copassengers, Lunar Flashlight likely spent just a few weeks installed on Falcon 9 before launching to the Moon. Additionally, the SLS launch trajectory took it more or less directly to the Moon, giving its rideshare payloads just a handful of days to troubleshoot any problems discovered. Thanks to the slower, more efficient transfer orbit SpaceX used to launch HAKUTO-R, JPL should still have opportunities to enter a nominal orbit even if Lunar Flashlight requires weeks of in-space troubleshooting – far more margin for error than most SLS copassengers received.
Lunar Flashlight weighs about 14 kilograms (~31 lb) at liftoff, features two sets of solar arrays, and packs a first-of-its-kind chemical propulsion system designed to deliver up to 290 m/s of delta-V – a ton of performance for such a small satellite. HAKUTO-R weighs closer to 1.1 tons (~2400 lb) and is a far more capable spacecraft, in theory – a necessity to land softly on the Moon. At ispace’s request, Falcon 9’s low-energy ballistic transfer orbit reduced the lander’s performance requirements, but it will need roughly 2000-2500 m/s of delta-V to enter lunar orbit and land on the lunar surface.
On December 12th, ispace confirmed that HAKUTO-R is in excellent shape around 24 hours after liftoff. ispace says the lander has secured stable communications, a stable orientation in space, and positive power generation from its solar arrays. An ispace infographic indicates that the spacecraft will enter lunar orbit around mid-April if all goes to plan. With HAKUTO-R in a stable state, the next most important near-term milestone will be the successful use of its propulsion and navigation systems. The startup hopes to demonstrate smooth deep space operations, including routine trajectory correction maneuvers, within one month of launch.
HAKUTO-R was SpaceX’s 56th successful launch of 2022 and the company’s second direct Moon launch this year after sending South Korea’s KPLO orbiter to the Moon in August.
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 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.
Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.
Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.

It looks a lot like a rocket — we all remember the shape in Austin 🤣 https://t.co/cFOPEuiJ4u

The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.
The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.
Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.
Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.
Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.
Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.
Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.
The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.
Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
