According to NASA, a SpaceX Falcon Heavy rocket (or another commercial heavy-lift launch vehicle) could potentially launch the bulk of a new Moon-orbiting space station in a single go, saving money and reducing risk.

Known as the Gateway, NASA is working to build a tiny space station in an exotic and odd orbit around the Moon. Lacking any clear and pressing purpose, NASA and the Gateway’s proponents have argued that it could serve as a testbed for interplanetary missions, allowing the space agency to figure out how to keep astronauts alive and healthy in deep space. Later, it was proposed as a sort of unwieldy orbital tug and home base for crewed Moon landers, although the Gateway appears to have recently been removed from any plans for mid-2020s Moon landings.

Most likely, the station is being built in order to give NASA’s wildly over-budget, behind-schedule Orion spacecraft and SLS rocket some kind of destination worthy of their gobsmacking $2-3 billion launch cost and $35-40 billion development cost. Regardless, a space station orbiting the Moon – while lacking a clear and present scientific or exploratory reason for its existence – is undeniably cool and exciting and will indeed need to be launched into cislunar space. Previously planned to launch as separate modules that would then rendezvous and dock in at the Moon, NASA has recently decided to switch gears.

According to NASA, the near-term arrival of launch vehicles with extra-large commercial fairings has motivated a change in its space station launch strategy. (SpaceX)

As of May 2020, NASA has awarded three critical hardware contracts for Gateway. In 2019, the space agency awarded contracts to Maxar and Northrop Grumman to build the Power and Propulsion Element (PPE) and Habitation and Logistics Outpost (HALO), respectively. As the name suggests, the PPE will feature an exceptionally large ~50 kW solar array and the most powerful electric thrusters ever flown in space, thus supplying Gateway with electricity and propulsion. HALO is a miniscule habitat module also responsible for life support and providing all other basic necessities for astronauts to live in space, all of which will leave a tiny amount of actual habitable volume for those astronauts to live in.

Most recently, NASA also awarded SpaceX a contract to develop a new Dragon XL spacecraft that will launch on Falcon Heavy and autonomously resupply the lunar space station at least twice, should Gateway actually make it to launch.

The notional plan is to eventually expand the habitable volume of the station from living in a large SUV to something more like a small studio apartment, a bit less than a third as large as the International Space Station (ISS) in a best-case scenario. The ISS is designed to support at least six astronauts simultaneously and has done so for almost two decades, albeit only with the help of resupply missions launched from Earth every 2-3 months. Indeed, the plan is to send up to four astronauts to the Gateway for no more than 90 days a year.

Two birds, one stone; two eggs, one basket

Originally, NASA wanted to launch the PPE and HALO modules – together representing the absolute bare minimum needed to build a functional Gateway – on separate commercial rockets in 2022 and 2023, respectively. Now, according to NASA associate administrator Doug Loverro, the space agency has made the decision to launch both modules simultaneously on the same commercial rocket.

In the next year or two, two new commercial rockets with spacious payload fairings (ULA’s Vulcan and Blue Origin’s New Glenn) could debut. A third, SpaceX’s Falcon 9 and Heavy rockets, will likely launch for the first time with a new extended payload fairing within the next 12-18 months. (Teslarati – ULA/NGIS/Blue Origin/SpaceX)

This decision was made in large part because it makes sense from a technical simplicity and overall efficiency standpoint but also because several commercial launch vehicles – either currently operational or soon to be – are set to debut extremely large payload fairings. As a combined payload, the Gateway PPE and HALO modules would be too big for just about any existing launch vehicle, while the tiny handful it might fit in lack the performance needed to send such a heavy payload to the Moon.

Falcon Heavy apparently has the performance needed, as NASA used the rocket and a new stretched fairing developed by SpaceX for military customers as a baseline to determine whether PPE and HALO could launch together. Given that NASA could have technically used any of the vehicles expected to have large payload fairings for that analysis, the explicit use and mention of Falcon Heavy rather strongly suggests that the SpaceX rocket is a front runner for the new combined launch contract. This isn’t exactly surprising, given that the massive rocket has already completed three successful launches and will attempt at least another four missions between now and 2023.

Of the other launch vehicles expected to feature large fairings capable of supporting the combined PPE/HALO payload, ULA’s Vulcan Centaur rocket is scheduled to launch for the first time in July 2021, while Blue Origin’s New Glenn is unlikely to launch before late 2021. Northrop Grumman is also developing the Omega rocket with a large fairing, although it’s unlikely to have the performance needed for the unique Gateway payload. As such, by 2023, Falcon Heavy will almost certainly have a record of launches well out of reach of other prospective PPE/HALO launch competitors. For obvious reasons, putting both modules of a space station on a single launch raises the stakes, making it more critical than ever than risk be reduced where it can be – especially important for launch operations.

Notionally including Gateway’s PPE and HALO, Falcon Heavy now has as many as nine launches on contract (or nearly so) over the next five or so years. It’s extraordinarily unlikely that any of Falcon Heavy’s prospective competitors will be able to get close to the SpaceX rocket’s flight history by 2023, effectively making Falcon Heavy the de facto choice for NASA from an apolitical, technical perspective.

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

Published

on

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.

Tesla expands Robotaxi geofence in Houston with an ode to SpaceX merger

Published

on

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.

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.
