After years of development, multiple prototypes constructed, and more than 1200 seconds of cumulative static fire testing at durations longer than what is needed to land on Mars, SpaceX propulsion engineers and technicians have successfully built and static-fired the first flight-worthy Raptor for the first time ever.

This is an incredibly important step towards BFR (Starship/Super Heavy) launch operations and is even more directly encouraging for the first integrated hop tests of SpaceX’s Starship prototype (unofficially deemed Starhopper), which could very well be the next host of the pathfinder Raptor engine pictured below.

In the scope of SpaceX’s history designing, building, and optimizing large-scale rocket engines, Raptor’s development likely followed a similar path. While Merlin 1 operates on a dramatically simpler combustion cycle (gas-generator), uses different fuel (kerolox vs. methalox), and is significantly less powerful and efficient than Raptor (as proposed), the workhorse engine went through a range of dramatically different iterations (Merlin 1A, 1B, 1C, and 1D) and is scarcely recognizable when its earliest block is compared to its most recent version. Merlin 1A began as an ablatively cooled 340 kN (76,000 lbf) engine, while the current workhorse (generally known as Merlin 1D Full Thrust, M1D FT) features a regeneratively-cooled nozzle and produces more than 840 kN (190,000 lbf), nearly a threefold improvement in thrust.

 

Raptor’s subscale prototype – featuring twice the chamber pressure of M1D (200 bar, ~3000 psi) and around the same maximum thrust as Merlin 1D (~1000 kN, 225,000 lbf) – can effectively be examined as the Merlin 1A to the Merlin 1C or 1D-class Raptor that SpaceX’s propulsion team settled on after learning from its smaller predecessors.

Performed on a Raptor-specific test cell at SpaceX’s McGregor, Texas “Rocket Ranch”, this milestone static fire was enabled by what one can safely assume were dozens or hundreds of lessons-learned over the course of two years of prototype engine testing and iterative improvement, working up to a quasi-final design that was shipped to Texas and installed just a few days ago. To kick off the first critical static fire of the pathfinder Raptor hardware, reports from ground observers indicate that SpaceX engineers began with a series of extremely short ‘blip’ tests that appeared perhaps 2-3 seconds from ignition to shutdown.

Starhopper’s one-stop hop spot

The immensely encouraging news of Raptor Block 1’s first successful static fire comes as SpaceX engineers, technicians, and contractors work around the clock to build both the first full-scale Starship prototype (nicknamed Starhopper) and the spartan pad it will lift off from during hop tests. SpaceX’s Boca Chica facilities were marked by a burst of pad-related activity over the last week or two, including the early installation of a range of pipes (some of it insulated for supercool cryogenic methane and oxygen) and the creation of a berm pointing towards the probable location of Starhopper’s simple launch mount and pad. ‘

While the Starship prototype’s three Raptor engines will dramatically outclass Falcon 9’s Grasshopper and F9R development vehicles (also used for hop tests), it’s possible that the same setup – basically a flat (refractory?) concrete pad with GSE (ground support equipment) protected behind a berm and automated water jet turrets around the vicinity – could work for Starhopper, too. For now, the successful static fire of the first post-development Raptor engine marks a massive step towards those initial hop tests and towards the first orbital launches of Starship and Super Heavy a bit further down the road. Stay tuned as SpaceX continues to extensively test Raptor and build out its Boca Chica pad and Starship prototype.

Tesla launches V2L Outlet Adapter for Premium Model Y in the U.S.

Published

Tesla has launched a new Vehicle-to-Load (V2L) Outlet Adapter for Premium Model Y vehicles in the United States, meaning you can now power devices like laptops or light strings with your vehicle’s battery.

It appears the capability will be available for any Model Y Premium trim, including those that were purchased prior to the Adapter being launched. It will also only impact Juniper Model Y vehicles, so the first-gen owners will unfortunately not have access to this capability.

If your Model Y was purchased before Tesla renamed the trim levels to “Premium” and “Standard,” it does not seem to be compatible. My Model Y is technically a Premium build, as it is the Long Range All-Wheel-Drive. However, Tesla says it is not compatible with my vehicle.

For $80, you can now utilize your car as a portable charger for small appliances or devices. This is perfect for things like tailgates, concerts, or camping, as you can now plug in devices that you might use. Those string lights for camping? That laptop for the other games that are on at the tailgate?

They’ll both utilize energy from your Tesla’s battery to be powered. This is the first time Tesla has expanded the capability to vehicles outside of the Model Y Performance and Cybertruck. However, this feature has been highly requested by owners for an extended period of time.

Tesla launched the Outlet Adapter in China last year:

You will need the Mobile Connector to operate the Outlet Adapter: the Outlet Adapter will plug into the main housing of the Mobile Connector, where the appropriate adapter to charge your vehicle will plug in.

It is rated for 120 volts and 20 amps, and has a max power rating of 2.4kW.

You can buy it here from Tesla for $80.

Tesla Roadster unveiling nears, and it will fly: The Information

Published

on

Tesla is nearing its long-awaited unveiling of the all-electric Tesla Roadster, a new report from The Information claims, as the company has said several times this year that the event would take place “soon.”

Now, it appears there is movement on Tesla’s end regarding when it will happen.

The report says that Tesla will unveil the Roadster as soon as this month with a SpaceX version that will utilize cold-gas thrusters to help the vehicle float for a short period of time. This is something CEO Elon Musk has talked about with the Roadster for years.

Additionally, due to the delays, Tesla explored “a variety of designs” for the Roadster, potentially planning to abandon the design it showed off for the first time in 2017 and adopting an entirely new aesthetic.

According to The Information, Tesla considered utilizing a repurposed Model S Plaid and even wanted to upgrade the look to something like a Lamborghini Countach.

Elon Musk teases Tesla Roadster unveiling once again

We’ve heard all of these things before, including teases about the date and how “soon” the Roadster will finally be ready to be shown off to the world (for the second time). Musk said that the event would occur in April, then May, then Chief Designer Franz von Holzhausen continued to say it would be coming “soon.”

We do expect to see the Roadster by the end of the year, and now with this new report swirling, it appears it could be sooner rather than later.

The wait has been incredibly long, but there is likely a good reason for it. Tesla’s desire to make the Roadster the craziest vehicle on the road was non-negotiable, and it likely took a lot of time and resources to develop and perfect into something that was safe and suitable for a vehicle like this.

Tesla finally got its Nevada Robotaxi Permit but with a few catches hard to miss

Nevada granted Tesla’s robotaxi permit, but capped the fleet at just ten vehicles for now.

Tesla has received its robotaxi permit in Nevada, more than two months after regulators closed the public comment period on the company’s application. News of the approval surfaced Wednesday night when Tesla investor and longtime company watcher Sawyer Merritt posted a copy of the interim order, and the Nevada Transportation Authority’s own carrier registry now lists the permit, AVNC Permit 002 under Docket 26-05015, as active for Tesla Robotaxi, LLC.

Tesla asked Nevada in June for authority to run up to 5,000 vehicles in Clark County within a year, however the permit the NTA issued is initially capping Tesla at ten fully autonomous vehicles and confines them to a defined geofence along the Las Vegas Strip corridor. Any expansion of that operating area, or any increase to the fleet size, requires the NTA’s approval first.

The order also sets rules that look more restrictive than what Tesla runs in Austin. Rides are barred on roads with posted speed limits above 45 miles per hour, pickups are off limits within a quarter mile of Harry Reid International Airport without separate authorization, and every vehicle has to carry visible “Robotaxi” markings while notifying riders before each trip that no one is driving. The order also requires “appropriate human supervision”, language that suggests Nevada isn’t ready to let Tesla offer the rides without a safety monitor that it has run in parts of Austin since January. As with standard protocol with robotaxi services, Tesla must report any accident, system failure, or vehicle that becomes stranded on a Nevada road within five business days.

Tesla is entering a market Nevada already knows well. Zoox, the Amazon owned robotaxi company, has run its own autonomous vehicle permit in the state since last year, building up to roughly 100 vehicles and 350,000 rides along the Strip. That history likely explains why the NTA started Tesla at ten cars rather than the fleet size the company asked for. The agency has a template for scaling a permit up once a company proves out its safety record.

Tesla’s Nevada application first surfaced in June, when the company filed for the permit alongside plans for a maintenance hub in southwest Las Vegas. The company has said it won’t meaningfully scale its robotaxi fleet anywhere until FSD v15 ships, expected in late 2026 or early 2027, which makes the ten vehicle cap less of a constraint today than it might look on paper. For now, Tesla has the legal right to start Nevada rides. Whether it starts before FSD v15 arrives is a separate question the permit doesn’t answer.
