SpaceX’s Starship rocket program just had one of its best nights yet

Published

on

Before dawn on May 4th, SpaceX successfully fueled a full-scale Starship prototype and (partially) tested an installed Raptor engine for the first time ever – perhaps the Starship program’s best night yet.

While just a small test relative to what’s soon to come, the milestone is still an extremely significant one for SpaceX and its next-generation launch vehicle. Designed to launch atop the Super Heavy booster, both Starship and its booster are meant to be fully reusable, potentially making the launch system one of the cheapest in operation on Earth. Despite that unprecedented full reusability, they should still be able to place dozens (perhaps up to 100-150+) metric tons of payload into orbit in a single launch.

To get to that point, however, SpaceX must develop and demonstrate a cornucopia of technologies and approaches – most of which are unprecedented – at a scale unmatched by ever other launch vehicle in history, save two or three. It was perhaps the most fundamental of those steps that was on the table earlier this morning.

Perhaps the single most important and uncertain part of SpaceX’s ambitious Starship architecture, SpaceX’s May 4th wet dress rehearsal (WDR) was mainly a test of Starship’s overall structure and the manufacturing apparatus SpaceX has created to build it. Despite how exotic and challenging some of Starship’s goals may sound, SpaceX’s approach to production for its newest launch vehicle is arguably the single biggest risk for the program.

Notably, CEO Elon Musk says that the ultimate goal is to roll out a single finished Starship rocket every single week and at a cost of something like $5-10 million per vehicle. Including the Super Heavy booster, the production goals of which remain unknown, SpaceX effectively wants to mass-produce dozens of fully-reusable rockets – all larger (and potentially more capable) than NASA’s Saturn V Moon rocket – for anywhere from a tenth to a hundredth of the cost.

As if those goals weren’t ambitious enough, SpaceX intends to achieve them with perhaps the most spartan, minimalist factory ever attempted for orbital-class rockets. At the moment, all Starship hardware built by SpaceX to date has been manufactured in a series of tents, more recently graduating to a trio of warehouse-sized sprung structures. A large hangar – apparently dedicated to building pad infrastructure – is just shy of complete, while a separate windbreak structure and a vertical assembly building (VAB) are used to stack (assemble) full-scale Starship subsections built inside tents.

Unlike almost every other launch vehicle in history, Starship production – excluding its Raptor engines and certain other subassemblies and parts – is done in tents and is almost entirely divorced of the clean room operations rocket factories are famous for. Despite the extensive use of hand-welded seams and parts on SpaceX’s early Starship prototypes, the company has already proven that it’s well on its way to building Starships in just a week or two.

Meanwhile, Starship SN5 will probably be ready to roll to the launch pad as early as next week, although it may have to wait a bit longer than that if Starship SN4 survives testing.

While it appears that SpaceX only performed a partial wet dress rehearsal with liquid methane and oxygen and completed a test of part of Starship SN4’s installed Raptor engine (known as the preburner), it means that a Starship has survived a truly launch vehicle-like procedure for the first time ever. In other words, Starship SN4’s May 4th success served as SpaceX’s most important verification yet that its exotic Starship manufacturing approach could be viable for building actual orbital-class rockets.

Up next, SpaceX will attempt to perform a full wet dress rehearsal (WDR) and a static fire test of Starship SN4 and its lone Raptor engine. That test attempt could come as soon as this evening.

Tesla launches new Model S and Model X, and the changes are slim

Tesla’s newest versions of its flagship vehicles have arrived with some slim changes.

Tesla has officially launched the newest versions of its flagship Model S and Model X vehicles, but the changes are pretty slim, which is something we expected when a couple cars were spotted during public testing recently.

The new “refreshed” Model S and Model X were spotted recently by The Kilowatts, and the changes appeared to be a new front camera, a new color, and only a handful of other changes.

Tesla officially announced the launch of the Model S and Model X on Thursday night, and here’s what it listed as the changes to the two vehicles:

  • Frost Blue paint color
  • Up to 410 miles of range (Model S Long Range – our longest range Tesla yet)
  • Even quieter inside: less wind + road noise & more effective Active Noise Cancellation
  • New wheel designs & improved aerodynamics = more range
  • Front fascia camera for better visibility
  • Dynamic ambient lighting that brings unique animations along the dash & doors upon entry
  • An even smoother ride thanks to new bushings & suspension design
  • Adaptive driving beams
  • New exterior styling for Model S Plaid, optimized for high-speed stability
  • More space for 3rd row occupants & cargo (Model X)

We expected most of these changes, especially the new Frost Blue paint color, as it was spotted by The Kilowatts in its initial coverage of the cars being spotted a few weeks back. Here’s what it looks like officially:

Some of the changes are familiar from the Model Y Refresh, which featured the quieter interior through acoustic-lined glass, a front fascia camera, new bushings, and suspension improvements for a smoother ride.

However, Tesla did refine the Model S Plaid’s exterior for “optimized high-speed stability.” You can see the difference between the two below:

The front-end air diffusers are much deeper, and the front end is more boxy than the previous iteration of the Plaid Model S.

Here are some more images of the Model S that Tesla released in a teaser video:

Tesla sells such a low volume of the Model S and Model X that it was probably less than likely that the company would put endless manpower and effort into completely redesigning it. CEO Elon Musk said a few years ago that the two cars would only stay in production for “sentimental reasons.” 

While they are very special to the Tesla family, they are not incredibly important to the mission of the company.

Tesla owners are already preparing for the company’s launch of the Robotaxi platform with a new, neat customization that is appearing around the world.

On Tuesday, the first Tesla Robotaxi test mule was spotted in Austin, where the company will launch the first driverless rides of this ride-hailing service. At first, it will be a limited rollout, reserved for a select few. CEO Elon Musk said public rides could occur as soon as June 22.

However, the Tesla Robotaxi platform is not one that will be confined to cities and geofenced to certain areas.

Eventually, Tesla will gain enough confidence to roll the Full Self-Driving software straight to every car in the customer fleet that paid for it. Owners will be able to generate income for themselves while they sleep, as the cars will operate as ride-hailing vehicles for people to use for transportation.

In an effort to prepare for the launch of Robotaxi, Tesla owners across the globe are installing Tesla’s ‘Robotaxi’ word art on their cars.

Here’s one in South Korea:

Here’s another in the U.S.:

Obviously, this is more of a symbol of support for the Robotaxi launch, but many owners are recognizing that Tesla’s Full Self-Driving software will extend to them the ability to use their personal cars as ride-hailing vehicles, becoming a part of the global fleet of self-driving chauffeurs.

Tesla sues former Optimus engineer for stealing trade secrets

Tesla is suing a former engineer who worked on Optimus after he left and immediately started a robotics company that achieved quick development of a hand.

Tesla is suing former Optimus engineer Jay Li in federal court after accusing him of stealing trade secrets and using them to enable a startup he founded after he left.

Li is accused of stealing confidential files and using them to help get his company, “Proception,” off to a rocking start. Tesla says the files Li took helped his new startup “shortcut the typical development process” for robot hands, something that took Tesla years to develop and evolve.

The company said in the complaint (via Reuters):

“Through Li’s pilfering, Defendant Proception purportedly achieved in a matter of months what it has taken Tesla over four years, hundreds of employees, and billions of dollars to achieve.”

Li was an employee at Tesla for several years, working on the Optimus sensor team from 2022 to 2024. The company says it utilized and devoted “extraordinary resources” to the development of Optimus, which has come a long way since its unveiling several years ago.

Li allegedly downloaded confidential files related to Optimus’ robotic hand movement research before departing the company. He did not work on the hands at the time. However, he left and swiftly started Proception, as the suit states the company was founded just six days after he left Tesla.

Proception was gloating about its ability to build robotic hands just five months after the company was founded. Tesla says the hands have “striking similarities” to its own design for Optimus.

The company is looking for monetary damages and a court order that would block Proception from misusing the secrets it accuses Li of taking.

This is not the first suit Tesla has filed over trade secrets and confidential information theft. Recently, it accused German-Canadian dual citizen Klaus Pflugbeil of stealing battery-related secrets. He was arrested and sentenced to two years in prison.

The U.S. Department of Justice used an undercover sting to arrest Pflugbeil.

Tesla is being represented by Josh Krevitt, Orin Snyder, and Angelique Kaounis of Gibson Dunn & Crutcher.

The case is Tesla Inc. v. Perception Inc., U.S. District Court for the Northern District of California, No. 5:25-cv-04963.
