SpaceX CEO Elon Musk has taken to Twitter to publish yet more photos of the company’s Starship Mk1 rocket prototype, this time posting what are – by far – the best official photos of Raptor engines yet taken.

This marks the first time that a SpaceX prototype of any kind has had more than one Raptor engine installed, a fairly symbolic but still significant milestone that follows in the footsteps of Starhopper’s successful single-engine flight test campaign. With Starhopper now heading into retirement, Starship Mk1 is preparing to support the program’s next major steps: full-scale, high-altitude flight tests powered by three Raptor engines.

The sight of three Raptor engines installed on the first true Starship prototype is undeniably hard to downplay. In barely seven months, SpaceX has gone from the very first static fire of a full-scale Raptor engine – serial number 01 – to flight-testing Raptor SN06 and producing enough engines to bestow Starship Mk1 with its own set of three engines. According to the latest comments from Elon Musk, Starship is meant to be powered by three ‘sea level’ Raptors and three vacuum-optimized Raptors – RVacs. RVac may or may not be ready to support the flight tests of early prototypes like Mk1 and Mk2, meaning that their three SL engines will likely be the sole propulsion for the time being.

Together, three SL Raptors operating at full thrust should be capable of producing up to 600 tons (1.3M lbf) of thrust. Per Musk’s note that Starship Mk1 likely weighs around 200 tons (~450,000 lb) empty, this means that a triple-engined Starship will be able to lift off with up to 400 tons (900,000 lb) of propellant, likely translating into roughly 200-300 seconds of untethered triple-engine operation.

“NOT FOR FLIGHT”

However, the engine installation milestone and subsequent photos are undeniably spectacular, but signs suggest that some level of pragmatism is in order. Visible in two of the three photos published by Musk, all three Raptors still have their transport rings installed just below each engine’s throat. Hardware at the base of one photo indicates that they were likely taken yesterday, on the evening of September 25th. Musk revealed that the three Raptors were installed late on September 22nd, up to three days prior.

Combined, the presence of the transport rings – “NOT FOR FLIGHT”, as their labels note – is a strong indicator that their installation is only temporary, likely in support of Elon Musk’s imminent September 28th Starship presentation. Without more information, it’s impossible to read much further into the temporary installation of Raptors. What it does confirm is that – for any number of reasons – flight-ready Raptors are not quite ready to support the Starship Mk1/Mk2. SpaceX has proven that Raptor is capable of supporting Starhopper for almost a full minute of powered flight, but behaviors observed near the end of that flight suggest that even that may have been pushing the engine’s limits.

All things considered, SpaceX is making progress at an almost unfathomable pace. Just seven months into full-scale Raptor test fires, it’s easy to believe that a lot of development work and refinement remains before the new engine family will be ready to reliably support multi-minute flight tests, let alone orbital launch attempts. Most orbital-class engine development programs aim for tens or even hundreds of thousands of seconds of test fires before attempting their first flights, but SpaceX is not most companies and is sticking closely to its preferred “test as you fly” methods and agile development strategies.

Autonomous vehicle red tape gets slashed by Trump Administration

Published

on

The Trump Administration today made several key moves to help with the deployment of autonomous vehicles by cutting overreaching red tape that has stifled growth and innovation for years.

The moves, which were put forth by the National Highway Traffic Safety Administration (NHTSA), aim to grant temporary exemptions to at least one company currently, although that could expand in the coming months. Additionally, it will work with organizations to develop standards and a sound but efficient regulatory landscape.

Zoox is the only company mentioned explicitly by the Trump Administration in its press release announcing the new terms today. They will receive a temporary two-year exemption that will allow the commercial deployment of up to 2,500 vehicles annually for two years.

There is a potential exemption for Robomart, Inc., which “requests a temporary exemption from certain FMVSS No. 500 requirements for a low-speed vehicle operated by an ADS without a human driver onboard. NHTSA will publish a separate notice seeking public comment on its merits once the initial evaluation is complete,” the agency said.

Here are the five new terms that Secretary Sean Duffy has implemented through the NHTSA today:

  1. Allow Zoox to commercially deploy its robotaxis through a temporary exemption.
    This temporary exemption will allow the commercial deployment of up to 2,500 vehicles annually for two years, subject to an enhanced, adaptable oversight structure that can evolve as Zoox’s technology advances.
  2. Accelerate development of first-ever AV performance standards through a partnership with SAE Industry Technologies Consortia (ITC).
    This partnership will fund a three-year, $5 million “A2SCEND” consortium, bringing together experts to gather data and accelerate creation of the first-ever AV performance standards. This project will inform a single national standard for AV safety to eliminate the patchwork regulatory landscape that has stifled innovation for years.
  3. Publish an interim final rule that allows vehicles manufactured prior to an exemption to be eligible for a commercial deployment exemption.
    This rule will modernize the application process and improve access to exemptions for innovators, including AV developers, by granting the NHTSA Administrator the discretion to apply temporary exemptions to vehicles manufactured prior to the effective date of an exemption grant.
  4. Streamline the application process for Part 555 exemptions by updating guidance and soliciting feedback from the public.
    By updating the Part 555 exemption process—which allows automakers to temporarily sell a limited number of non-compliant vehicles, primarily to test new technologies—NHTSA is aiming to create a more flexible oversight structure for exemptions and summarize recent AV framework activities, including expanded exemption pathways, streamlined crash reporting, and ongoing efforts to modernize Federal Motor Vehicle Safety Standards (FMVSS).
  5. Establish a new Federal Docket for public feedback on NHTSA’s updated safe AV development and deployment guidance.
    NHTSA is updating its technical guidance for AVs for the first time since 2017—focusing on key safety areas like emergency responder interactions, safety management systems, remote assistance, and post-crash behavior to help the industry scale up driverless deployments safely.

Additionally, the NHTSA said it has modernized some safety standards by proposing updates to:

  • FMVSS 102 – Transmission shifting
  • FMVSS 103/104 – Windshield defrosting and wiping
  • FMVSS 110 – Tire placards
  • FMVSS 135 – Braking systems
  • FMVSS 101 – Controls and displays
  • FMVSS 108 – Vehicle lighting
  • FMVSS 111 – Mirrors and rearview display
  • FMVSS 126 – Electronic stability control systems
  • FMVSS 201/208 – Sun visors and warning labels

These changes aim to make the regulatory process for autonomous vehicles more streamlined and efficient, which could help the U.S. gain dominance over autonomous vehicle systems moving forward.

Elon Musk has a crazy prediction about AI in two years

Elon Musk is, in many respects, one of the biggest and most influential figures in modern-day artificial intelligence.

Given that Tesla, SpaceX, and xAI are all looked at in their respective fields as leaders to an extent, each of them has a heavy influence on the future of AI, even though two of them are not thought of, at face value, as AI companies.

Musk has grand expectations for what is to come with AI, not only as a form of assistance to make human lives easier, but to make humans multiplanetary and solve some of the biggest issues that face us today. But even he is astounded by AI’s pace of progress.

He believes that in two years, AI will be so mind-blowing it might be unrecognizable.

This progress can be seen in a variety of ways, but perhaps the most popular way people have shown AI’s progress, especially on social media, is through an incredibly arbitrary way of watching Will Smith eat spaghetti:

This is a great way to show people how AI is improving, especially from a perspective that examines how it can manufacture images and video from prompts. AI is an incredibly complex concept, however, and it goes much deeper than Will Smith eating Italian food.

Musk’s most widely adopted method of AI is likely Tesla Full Self-Driving, which impacts millions of people as they utilize it to increase safety with their travel. Musk has routinely pushed incredibly aggressive timelines for self-driving, especially unsupervised.

Perhaps this perspective is why he feels that things will be solved in a timeframe that is much more aggressive than most of us would think. Regardless, the progress of AI is moving fast, and it seems that Musk’s expectations for it could be high.

But if it can actually achieve full-length motion pictures and even more realistic production value, it will be hard to distinguish between reality and AI very soon.

Tesla just built it 10 millionth car

Published

Tesla just officially confirmed it has built its 10 millionth car, a major milestone for the company that started producing sustainable electric powertrains less than two decades ago.

In that time, Tesla has truly revolutionized the automotive industry, disrupting the idea of what a car should be, how it should be fueled, and how it truly impacts day-to-day life.

Tesla achieved this feat across four production facilities: the Fremont Factory in Fremont, California, Gigafactory Shanghai in China, Gigafactory Berlin in Germany, and Gigafactory Texas in Austin, Texas.

The 10 millionth vehicle was a Diamond Black Model Y.

Over the course of the past roughly 18 years, Tesla has evolved its lineup from a sporty sedan built on a Lotus body to a lineup of various body styles, performance metrics, and other characteristics that make each one unique.

This is an incredible achievement for a company that is young compared to what it goes up against. When Tesla entered the automotive market, Ford, GM, and Stellantis widely dominated the playing field. Since then, Tesla has caused such a disruption that these three massive brands had to scramble to create EV projects of their own.

Despite their best efforts, they have not been able to match the prowess or the effectiveness of Tesla. They are all reliant on Tesla’s charging infrastructure, their software is inferior, and their self-driving projects are elementary in comparison.

Tesla felt its fair share of growing pains over the years as well. As recent at 2019, there were complaints about build quality, paint quality, and overall luxuriousness. These things have all been improved upon through the company’s maturity, and these strides in quality have led to this 10 million vehicle production achievement, something that other small-and-scrappy EV makers will hope to accomplish one day.
