In its true last act of the year, SpaceX successfully fired up its first orbital-class Starship for the fourth time in approximately two months, placing the prototype one step closer to flight readiness.
Starship S20 first left its roost in SpaceX’s Starbase factory in early August, briefly performing a fit test atop Super Heavy Booster 4 (B4) – both only partially complete at the time. Both returned to their nests for finishing touches soon after. However, relative to almost all other prototypes SpaceX has built in South Texas in the last two years, Starship S20’s path to flight readiness has been a long and windy one. It took SpaceX a full eight weeks after that first rollout to prepare Ship 20 for – and complete – its first cryogenic proof test, in which the rocket was pressurized and filled with hundreds of tons of liquid nitrogen (LN2).
It took another three weeks after that milestone for SpaceX to then prepare Ship 20 for an even more important test – its first Raptor engine static fire.
The process began on October 19th with Ship 20’s first Raptor preburner test, in which smaller secondary combustion chambers designed to supply the engine’s main combustion chamber with a combustible mixture were briefly ignited on their own. On October 21st, that next milestone finally came, with Starship S20 not only completing the first on-pad static fire of a Raptor Vacuum engine but also performing a second test during the same window, firing up the same RVac and a gimballing Raptor Center (RC) engine less than an hour later. It was an impressive leap in apparent confidence, with Ship 20 jumping from the slowest prototype to reach a testing milestone to the first prototype of any kind to complete back-to-back static fires less than an hour apart.
After another unusually long three weeks of work, some of which was spent installing four more Raptors on Starship S20, the ship completed a second preburner test – the first of any kind to simultaneously feature or involve six Raptor engines. Unlike the first campaign, which had a two-day gap, SpaceX then turned S20 around in the same window and performed the first six-Raptor Starship static fire 50 minutes later – both a success, according to CEO Elon Musk.
Another Ship 20 static fire was subsequently attempted another three or so weeks later, ultimately resulting in an abort on December 1st. Only four weeks later did SpaceX try again, successfully completing what appeared to be Starship S20’s second six-engine static fire without issue on December 29th. The company attempted a second static fire a few hours later but that try was less lucky, culminating in an abort seconds before ignition and wrapping up the day’s testing. That brings us to today, January 2nd, 2022, where SpaceX is once again preparing for more Ship 20 testing with eight-hour windows on January 4th, 5th, and 6th.
The goals of these continued static fire tests are less clear than some past SpaceX testing but Ship 20 – the first orbital-class prototype and first Starship to test more than three Raptors at a time – is a valuable pathfinder. While SpaceX would likely have benefitted even more from them weeks or months, all lessons learned from Ship 20 will help guide retroactive modifications and proactive design changes for upcoming prototypes – the statuses of which are currently in flux.

Tesla celebrates 75k Superchargers, less than 5 months since 70k-stall milestone
Tesla’s 75,000th stall is hosted at the South Hobart Smart Store on Cascade Road, South Hobart, Tasmania.
Tesla has crossed another major charging milestone by officially installing its 75,000th Supercharger stall worldwide. The electric vehicle maker chose South Hobart, Tasmania, as the commemorative location of its 75,000th Supercharger.
Tesla’s 75,000th Supercharger
Tesla’s 75,000th stall is hosted at the South Hobart Smart Store on Cascade Road, South Hobart, TAS 7004, as noted in a techAU report. The location features four next-generation V4 Superchargers, which are built with longer cables that should make it easy even for non-Teslas to use the rapid charger. The site also includes simplified payment options, aligning with Tesla’s push to make V4 stations more accessible to a broader set of drivers.
For Tasmanian EV owners, the installation fills an important regional gap, improving long-distance coverage around Hobart and strengthening the area’s appeal for mainland travelers traveling by electric vehicle. Similar to other commemorative Superchargers, the 70,000th stall is quite special as it is finished in Glacier Blue paint. Tesla’s 50,000th stall, which is in California, is painted a stunning red, and the 60,000th stall, which is in Japan, features unique origami-inspired graphics.
Accelerating Supercharger milestones
The Tesla Supercharger’s pace of expansion shows no signs of slowing. Tesla celebrated its 70,000th stall at a 12-stall site in Burleson, Texas late June 2025. Just eight months earlier, Tesla announced that it had celebrated the buildout of its 60,000th Supercharger, which was built in Enshu Morimachi, Shizuoka Prefecture, Japan.
Tesla’s Supercharger Network also recently received accolades in the United Kingdom, with the 2025 Zapmap survey naming the rapid charging system as the Best Large EV Charging Network for the second year in a row. Survey respondents praised the Supercharger Network for its ease of use, price, and reliability, which is best-in-class. The fact that the network has also been opened for non-Teslas is just icing on the cake.

Luminar-Volvo breakdown deepens as lidar maker warns of potential bankruptcy
The automaker stated that Luminar failed to meet contractual obligations.
Luminar’s largest customer, Volvo, has canceled a key five-year contract as the lidar supplier warned investors that it might be forced to file for bankruptcy. The automaker stated that Luminar failed to meet contractual obligations, escalating a dispute already unfolding as Luminar defaults on loans, undergoes layoffs, and works to sell portions of the business.
Volvo pulls back on Luminar
In a statement to TechCrunch, Volvo stated that Luminar’s failure to deliver its contractual obligations was a key driver of the cancellation of the contract. “Volvo Cars has made this decision to limit the company’s supply chain risk exposure and it is a direct result of Luminar’s failure to meet its contractual obligations to Volvo Cars,” Volvo noted in a statement.
The rift marked a notable turn for the two companies, whose relationship dates back several years. Volvo invested in Luminar early and helped push its sensors into production programs, while Luminar’s technology bolstered the credibility of Volvo’s safety-focused autonomous driving plans. Volvo’s partnership also supported Luminar’s 2020 SPAC listing, which briefly made founder Austin Russell one of the youngest self-made billionaires in the industry.
Damaged Volvo relations
The damaged Volvo partnership comes during a critical period for Luminar. The company has defaulted on several loans and warned investors that bankruptcy remains a possibility if restructuring discussions fall through. To conserve cash, Luminar has cut 25% of its workforce and is exploring strategic alternatives, including partial or full asset sales.
One potential buyer is founder Austin Russell, who resigned as CEO in May amid a board-initiated ethics inquiry. The company is also the subject of an ongoing SEC investigation.
Luminar, for its part, also noted in a filing that it had “made a claim against Volvo for significant damages” and “suspended further commitments of Iris” for the carmaker. “The Company is in discussions with Volvo concerning the dispute; however, there can be no assurance that the dispute will be resolved favorably or at all,” the lidar maker stated.

Elon Musk says he’s open to powering Apple’s Siri with xAI’s Grok
Siri, one of the first intelligent AI assistants in the market, has become widely outdated and outperformed by rivals over the years.
Elon Musk says he’s willing to help Apple overhaul Siri by integrating xAI’s Grok 4.1, igniting widespread excitement and speculations about a potential collaboration between the two tech giants.
Siri, one of the first intelligent AI assistants in the market, has become widely outdated and outperformed by rivals over the years.
Musk open to an Apple collaboration
Musk’s willingness to team up with Apple surfaced after an X user suggested replacing Siri with Grok 4.1 to modernize the AI assistant. The original post criticized Siri’s limitations and urged Apple to adopt a more advanced AI system. “It’s time for Apple to team up with xAI and actually fix Siri. Replace that outdated, painfully dumb assistant with Grok 4.1. Siri deserves to be Superintelligent,” the X user wrote.
Musk quoted the post, responding with, “I’m down.” Musk’s comment quickly attracted a lot of attention among X’s users, many of whom noted that a Grok update to Siri would be appreciated because Apple’s AI assistant has legitimately become terrible in recent years. Others also noted that Grok, together with Apple’s potential integration of Starlink connectivity, would make iPhones even more compelling.
Grok promises major Siri upgrades
The enthusiasm stems largely from Grok 4.1’s technical strengths, which include stronger reasoning and improved creative output. xAI also designed the model to reduce hallucinations, as noted in a Reality Tea report. Supporters believe these improvements could address Apple’s reported challenges developing its own advanced AI systems, giving Siri the upgrade many users have waited years for.
Reactions ranged from humorous to hopeful, with some users joking that Siri would finally “wake up with a personality” if paired with Grok. Siri, after all, was a trailblazer in voice assistants, but it is currently dominated by rivals in terms of features and capabilities. Grok could change that, provided that Apple is willing to collaborate with Elon Musk’s xAI.
