SpaceX teams have finally safed the fourth full-scale Starship prototype nearly two days after a Raptor engine test caught it on fire, an anomaly that left the massive rocket charred and damaged – but still intact.

While SN4’s survival is a welcome and unexpected outcome, the fire that broke out near the base of the rocket caused damage that will have to be repaired, while the fault that allowed that fire to occur in the first place will also need to be rectified. Had the same events transpired during the ship’s inaugural flight test, things could have gone even further south after the rocket lifted off, carrying it away from remotely-controlled water jets used to suppress unplanned fires on the pad.

Thankfully, SpaceX’s focus on testing, testing, and testing some more meant that Starship SN4’s minor self-immolation occurred on the ground when the stakes – while high – were much lower than they would have been with an airborne rocket. The problems uncovered will, of course, need to be fixed, inevitably delaying the ship’s first flight test, but odds are that SN4 now has a better shot at success thanks to those hiccups.

Thanks to the fact that Starships are constructed almost entirely out of steel, a little (or a lot of) fire shouldn’t theoretically be much of a problem. However, SpaceX has taken a rather freeform approach to its early Starship SNx prototypes, opting to bolt, weld, or tape on the vast majority of external hardware with little or no protection from the elements, including fires ignited by the ships themselves.

With SN4, it appears that the pressure jump experiences immediately after Raptor ignition (the ship’s third such test) shook some methane-related plumbing loose. Raptor continued to burn for another five or so seconds after that minor failure, shutting down as planned – but not before it ignited the methane the burst pipe was leaking. Additionally, after that new plume of boiling liquid methane caught fire, the fire it sustained proceeded to ignite insulation wrapped around the rocket’s launch. It burned vigorously, likely helping to damage wiring, ultimately causing SpaceX to partially lose control of the rocket and preventing attempts to inspect and fix the damage for two full days.

It’s safe to say that SpaceX is probably going to prioritize avoiding the series of events that caused May 19th’s anomaly from here on out, considering that things could have easily gone much worse. Thankfully, whatever control SpaceX or the rocket itself retained after wire damage allowed it to safely offload its flammable propellant and vent expanding gases to prevent SN4’s tanks from bursting. Installing highly flammable insulation approximately 10 feet away from an active Raptor engine and giant controlled fire and explosion was also inadvisable and probably won’t be repeated.

Thankfully, the damage is clearly minimal and Starship SN4 survived the ordeal otherwise unscathed. With any luck, inspections and repairs will be quick and easy and SpaceX – as NASASpaceflight reporter Michael Baylor notes – will be able to complete an identical static fire test without starting a fire on Starship SN4. SpaceX has requested a new road closure (signifying planned testing) on May 28th with backup windows on May 29th and June 1st.

Thanks to Starship SN4’s unplanned delays, it now looks quite likely that SpaceX’s next full-scale Starship prototype (SN5) will be completed – or nearly so – by the time that its predecessor is cleared for flight. “Too many Starships” is certainly a welcome problem to have.

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.
