High winds scrub SpaceX Starship SN9’s Monday launch attempt

Published

Update (2:30 pm CST): SpaceX appears to have called off Monday’s Starship SN9 launch attempt due (primarily) to high winds along the flight corridor. Additional opportunities are available from 8 am to 6 pm CST (UTC-6) on Tuesday (Jan 26) and Wednesday (Jan 27).

Technically, lacking any official confirmation, there’s still a chance of a launch attempt or additional ground testing happening today but either possibility is extremely unlikely at this point.

Update: SpaceX has completed what is known as a Flight Readiness Review (FRR) and determined that Starship prototype SN9 is ready to attempt its first high-altitude launch as early as today.

All necessary aviation and maritime notices and restrictions are in place and the company has begun the process of closing a public highway and clearing the launch site of employees. Today’s (Jan 25) launch window lasts from noon to 6 pm CST (UTC-6) and Starship SN9 could likely be made ready to launch anytime after 2pm be ready to fly as early as 4 pm CST according to a loudspeaker announcement at the launch pad. Stay tuned for updates and, hopefully, an official SpaceX webcast.

All signs point to SpaceX’s second high-altitude Starship prototype preparing for a 12.5-kilometer (~40,000 ft) as early as Monday, January 25th in a bid to rectify a last-second bug that caused its predecessor to explode last month.

Known as Starship serial number 8 (SN8), the SpaceX-built prototype was the first to have its basic airframe (tank and nose sections) fully integrated, as well as the first Starship to attempt to break the 150m (~500 ft) ceiling set by Starhopper, SN5, and SN6. Break the ceiling SN8 most certainly did, performing a spectacularly successful 12.5 km launch that aced almost every single goal SpaceX had hoped to complete. Keyword almost.

After an impressive 280 seconds of uninterrupted operation of its Raptors, Starship SN8 shut down the last of those three engines, flipped onto its belly, and successful freefell ~12 kilometers back to Earth. The rocket then carried that success even further, reigniting two Raptors, performing a dramatic 120-degree flip, orienting itself vertically, and beginning to slow down for a soft landing.

Only then did Starship SN8’s performance deviate from virtual perfection. At T+6:38, a few seconds after beginning its crucial landing burn, one of Starship’s active Raptors shut down and the other effectively stopped generating thrust. The reason, CEO Elon Musk would later explain, was low head pressure in a smaller tank (‘header tank’) dedicated to supplying fuel during Starship’s wild flip and landing maneuver. It was never confirmed if the Raptor engine shutdown observed milliseconds prior to the other engine losing thrust was intentional.

Cause aside, the end result was unsurprising: without enough thrust to slow down, Starship SN8 accurately impacted the concrete landing zone but did so at high speed – likely around 50-60 m/s (100-150 mph). Given that Starhopper and Starships SN5 and SN6 had already successfully proven Starship’s ability to gently land from 150 meters on a single Raptor engine and that, prior to SN8, Starship’s bizarre belly-flop descent and 90-degree flip had been almost entirely theoretical, SpaceX deemed the launch a spectacular success.

Nothing better exemplifies that than the fact that a little over a month later, SpaceX quite literally began scrapping the most complex, completed section of a future Starship prototype (SN12) before it ever reached the assembly phase. Instead, SpaceX appears to be more focused than ever on a mysterious series of “major” upgrades Musk has said will debut on Starship SN15. Nearly all SN15 subsections have been completed and are simply waiting to be joined together, while parts of SN16 and SN17 are also starting to pile up in staging areas.

Starship SN10 is practically ready to move to the launch pad to prepare for flight as soon as SpaceX chooses to do so and Starship SN11 is likely no more than a week or two of work away from reaching same level of readiness.

Ultimately, despite a long and delay-ridden test campaign, Starship SN9 finally completed what looked like a full-duration static fire of all three of its Raptor engines – the rocket’s sixth static fire overall. On Saturday, January 23rd, SpaceXers installed SN9’s flight termination system (FTS) – a system of explosives designed to destroy Starship if it flies too far off course. For Starship, FTS installation all but guarantees that a launch attempt is a matter of days away. Fresh county roadblocks, Temporary Flight Restrictions (TFRs) granted by the FAA, and Coast Guard a safety notice further imply that SN9 will attempt to launch as early as Monday morning, January 25th, with backup opportunities on Tuesday and Wednesday.

With any luck, like SN8’s high-altitude debut, SpaceX hopefully livestream Starship SN9’s own attempt at the same feat. Stay tuned for more details as they come.

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.
