High winds scrub SpaceX Starship SN9’s Monday launch attempt

Published

on

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.

xAI’s Grokipedia goes live, gets praise from Wikipedia co-founder

xAI’s latest creation, Grokipedia, has gone live, and even if it’s only at Version 0.1, it is already receiving positive reviews from some users.

xAI’s latest creation, Grokipedia, has gone live, and even if it’s only at Version 0.1, it is already receiving positive reviews from some users. These include Larry Sanger, the co-founder of Wikipedia, the world’s largest online encyclopedia, which has become quite controversial in recent years over accusations of bias.

Grokipedia launches

Immediately after Grokipedia went live, the AI-powered Wikipedia alternative was tested by numerous users. So far, a good number of testers have responded positively to the online encyclopedia, with many observing that Grokipedia does tend to be more neutral than Wikipedia. This was particularly evident in controversial topics, from alternative medicine to events like Gamergate.

Among these users was Larry Sanger, who noted that while Grokipedia still has a lot of areas of improvement, it is already very promising. “My initial impression, looking at my own article and poking around here and there, is that Grokipedia is very OK. The jury’s still out as to whether it’s actually better than Wikipedia. But at this point I would have to say “maybe!” He wrote in a post on X. 

Musk responded to Sanger’s comments, stating that the Wikipedia co-founder’s observations are “accurate.” The xAI founder also noted in a separate X post that even in its V0.1 form, Grokipedia is already better than Wikipedia. 

Why Grokipedia exists 

During an interview on the Tucker Carlson Show, Sanger point out that Wikipedia has become a far cry from his initial vision for the online encyclopedia, and a lot of this was because of the its “Reliable sources/Perennial sources” page, which categories publications and sources into tiers of credibility. Sanger noted that the list leaned heavily left, with conservative publications getting effectively blacklisted in favor of their more liberal.

Musk responded to Sanger’s comments by stating that Grokipedia will be created as a step towards xAI’s broader goal of “understanding the Universe.” He added that Grokipedia, which will use xAI’s Grok, would provide broader sourcing and a freer exchange of information compared to Wikipedia’s current system. 

One month after Elon Musk’s comments, Grokipedia has gone live in its V0.1 form.

Tesla is marking the 15-year anniversary of its Fremont Factory in California, the first automotive mass-manufacturing plant acquired by the electric car maker. 

Since opening in 2010, the Fremont Factory has produced all four “S3XY” models while creating tens of thousands of jobs and investing billions of dollars in the region.

Celebrating 15 years of EV production

The Fremont Factory’s milestone was celebrated by the official Tesla Manufacturing account on X, which posted a photo of several Teslas forming a “15” in front of the facility’s iconic white facade. As per the electric vehicle maker, the Fremont Factory has now produced 3.6 million vehicles so far, and it has also created over 20,000 jobs in the state. 

“15 years ago, we opened Fremont factory. Today, the Fremont team is producing all 4 S3XY models, totaling 3.6M vehicles made so far. 20k+ California jobs created w/ billions of dollars invested,” the official Tesla Manufacturing account on X wrote in its post.

The Fremont Factory’s transformation

Tesla acquired the Fremont Factory from the defunct NUMMI joint venture between General Motors and Toyota in May 2010 for $42 million. The facility had produced more than 8 million vehicles under GM and Toyota over 26 years. Following its acquisition, Tesla retooled the 5.3-million-square-foot plant to support the production of the Model S sedan.

Over the past 15 years, the factory has evolved into Tesla’s primary North American production hub, assembling the Model S, 3, X, and Y. Annual output has exceeded 550,000 vehicles, including nearly 560,000 produced in 2023 alone. Expectations are high that other products, such as the next-generation Roadster and Optimus, might be produced in the Fremont Factory as well.

Tesla has opened its first job listing specifically for the next-generation Roadster, hinting at some substantial progress on the company’s long-awaited flagship all-electric supercar. 

The company is looking for a Manufacturing Engineer to support the development and launch of new battery manufacturing equipment, which would likely be pivotal to the Roaster, considering its teased performance and range.

Tesla’s next-generation Roadster batteries

As per Tesla’s Careers website, the Roadster Manufacturing Engineer’s tasks would include ideating equipment concepts, developing specifications, validating processes, and addressing production bottlenecks. Tesla emphasized that the position involves collaboration across domestic and international sites, supporting equipment factory acceptance tests and assisting operations teams, with expected travel under 50 percent. 

“In this role, you will take large-scale manufacturing systems for new battery products and architectures from the early concept development stage through equipment launch, optimization, and handover to local operations teams. Battery development is at the heart of our company, and this is an exciting opportunity to work directly on the central challenges for the all-new Roadster product architecture while still in its early development stages,” the job listing noted.

The opening marks one of the first public hiring efforts explicitly tied to the next-gen Roadster, suggesting that the vehicle’s development might be approaching its initial manufacturing phase. The fact that the new Roadster’s first job opening is related to its battery is interesting, as the vehicle was unveiled with a range of 620 miles way back in late 2018. Though at the time, Elon Musk also noted that the Roadster would be fitted with a 200 kWh battery, twice the size of the batteries used in the Model S and Model X.

Musk teases “most epic demo ever” and fuels Roadster speculation

Back in July, Elon Musk teased a major demonstration at the Tesla Design Studio in Hawthorne, California, scheduled for the end of the year. Musk shared on X that he had just visited the studio, calling the upcoming event the “most epic demo ever by one of year. Ever.”

The statement immediately prompted speculations that Tesla may finally be ready to reveal the production version of the next-generation Roadster. Originally unveiled alongside the Semi in 2018, the Roadster has remained under wraps while the company scaled production of other models. Since its unveiling, however, the Roadster’s rollout has been pushed back in favor of the original Model Y, the refreshed Model S and X, the Cybertruck, the refreshed Model 3, the Semi, and the new Model Y.

At the time of its unveiling, the next-generation Roadster was teased to be nothing short of a monster, with a 0-60 mph time of 1.99 seconds and a top speed of over 250 mph. Elon Musk also teased that the next-generation Roadster would have a range of 620 miles per charge. Later, the CEO noted that the Roadster should be able to achieve a 0-60 mph launch of less than 1 second, thanks to the vehicle’s SpaceX package. Musk has also noted recently that the next-generation Roadster would be “beyond a car.”
