SpaceX’s Starship briefly becomes the most powerful active rocket in the world
A SpaceX Starship booster has successfully fired up 14 of its 33 Raptor engines, likely becoming the most powerful active rocket in the world.
Throughout the history of spaceflight, only three or four other rockets have produced as much or more thrust than Super Heavy Booster 7 (B7) could have theoretically produced on November 14th. But the Soviet Energia and N1 rockets and the US Saturn V and Space Shuttle were all retired one or several decades ago. Only SpaceX’s own Falcon Heavy rocket, fifth on the bracket and capable of producing up to 2325 tons (5.13 million pounds) of thrust at sea level, is still operational and comes close.
Powered by 33 upgraded Raptor 2 engines that SpaceX says can produce up to 230 tons (~510,000 lbf) each, Super Heavy could have produced up to 3220 tons (7.1 million pounds) of thrust when it ignited 14 of its engines earlier today. That likely means that Starship is now the fourth most powerful rocket ever tested, slotting in above NASA’s Space Shuttle but below the Soviet Energia. And even if all 14 engines never throttled above 73%, SpaceX’s Starship booster likely still produced more thrust than any other active rocket in the world, beating Falcon Heavy. But if NASA has its way, Starship could hold that title for less than 36 hours.
As early as 1:04 am EDT (06:04 UTC) on November 16th, a little over 35 hours after SpaceX’s record-breaking Starship static fire, NASA will attempt to launch its massive Space Launch System (SLS) rocket for the third time since late August. At the explicit request of Congress, which wanted to preserve Shuttle jobs after the end of the program in 2011, SLS essentially shuffles around Space Shuttle parts and replaces the reusable orbiter with a fully-expendable rocket. The Solid Rocket Boosters (SRBs) have been extended and uprated, and the orange External Tank has been stretched and turned into a liquid rocket booster affixed with four RS-25 engines to the Shuttle’s three.
If things go according to plan, those changes mean that SLS rocket will produce up to 3990 tons (8.8 million pounds) of thrust when it lifts off for the first time, overtaking Super Heavy B7 but also making it the second most powerful launch vehicle in history after the Soviet N1. N1 never succeeded, however, so SLS could become the most powerful rocket ever to reach orbit if its first launch is successful.
But just as SLS appears poised to almost immediately unseat Starship’s position as the most powerful active rocket in the world, Starship is poised to beat SLS to become the most powerful rocket ever flown – successfully or not – when it attempts its first orbital launch either next month or early next year. With all 33 Raptors at full throttle, Starship can produce almost 7600 tons (16.7 million pounds) of thrust at liftoff, beating the previous record-holder – the Soviet N1 rocket – by nearly 60%.
Even if that first launch attempt is unsuccessful, SpaceX appears to be preparing for several more rapid-fire launches that will continue until success is achieved, beating SLS’ other (potential) record. SpaceX has demonstrated that ability once before with Starship when it completed five flights of five different prototypes in less than six months. As a result, it’s likely that by the time SLS launches a second time in the mid-2020s, it will be the third most powerful rocket, second to N1 and Starship.
That slightly awkward upset should be lessened by the fact that Starship and SLS are, for the time being, both integral parts of NASA’s Artemis Program. To return astronauts to the Moon for the first time since 1972, SLS and its Orion spacecraft will transport NASA astronauts to lunar orbit, where they’ll board a Starship-derived Moon lander. Starship will then land those astronauts on the lunar surface, support about a week of surface operations, and then return them to lunar orbit, where Orion will transport them back to Earth.
For now, a massive amount of work remains to be done before NASA and SpaceX will be ready to support that crewed Moon landing. But Monday’s Starship static fire and Wednesday’s potential SLS launch both represent significant, tangible steps towards that lofty goal.

Tesla confirmed HW3 can’t do Unsupervised FSD but there’s more to the story
Tesla confirmed HW3 vehicles cannot run unsupervised FSD, replacing its free upgrade promise with a discounted trade-in.
Tesla has officially confirmed that early vehicles with its Autopilot Hardware 3 (HW3) will not be capable of unsupervised Full Self-Driving, while extending a path forward for legacy owners through a discounted trade-in program. The announcement came by way of Elon Musk in today’s Tesla Q1 2026 earnings call.

The history here matters. HW3 launched in April 2019, and Tesla sold Full Self-Driving packages to owners on the understanding that the hardware was sufficient for full autonomy. Some owners paid between $8,000 and $15,000 for FSD during that period. For years, as FSD’s AI models grew more demanding, HW3 vehicles fell progressively further behind, eventually landing on FSD v12.6 in January 2025 while AI4 vehicles moved to v13 and then v14. When Musk acknowledged in January 2025 that HW3 simply could not reach unsupervised operation, and alluded to a difficult hardware retrofit.
The near-term offering is more concrete. Tesla’s head of Autopilot Ashok Elluswamy confirmed on today’s call that a V14-lite will be coming to HW3 vehicles in late June, bringing all the V14 features currently running on AI4 hardware. That is a meaningful software update for owners who have been frozen at v12.6 for over a year, and it represents genuine effort to keep older hardware relevant. Unsupervised FSD for vehicles is now targeted for Q4 2026 at the earliest, with Musk describing it as a gradual, geography-limited rollout.
For HW3 owners, the over-the-air V14-lite update is welcomed, and the discounted trade-in path at least acknowledges an old obligation. What happens next with the trade-in pricing will define how this chapter ultimately gets written. If Tesla prices the hardware path fairly, acknowledges what early adopters are owed, and delivers V14-lite on the June timeline it committed to today, it has a real opportunity to convert one of the longest-running sore subjects among early adopters into a loyalty story.

Tesla isn’t joking about building Optimus at an industrial scale: Here we go
Tesla’s Optimus factory in Texas targets 10 million robots yearly, with 5.2 million square feet under construction.
Tesla’s Q1 2026 Update Letter, released today, confirms that first generation Optimus production lines are now well underway at its Fremont, California factory, with a pilot line targeting one million robots per year to start. Of bigger note is a shared aerial image of a large piece of land adjacent to Gigafactory Texas, that Tesla has prominently labeled “Optimus factory site preparation.”
Permit documents show Tesla is seeking to add over 5.2 million square feet of new building space to the Giga Texas North Campus by the end of 2026, at an estimated construction investment of $5 billion to $10 billion. The longer term production target for that facility is 10 million Optimus units per year. Giga Texas already sits on 2,500 acres with over 10 million square feet of existing factory floor, and the North Campus expansion is being built to support multiple projects, including the dedicated Optimus factory, the Terafab chip fabrication facility (a joint Tesla/SpaceX/xAI venture), a Cybercab test track, road infrastructure, and supporting facilities.
Texas makes strategic sense beyond the existing infrastructure. The state’s tax structure, lower labor costs relative to California, and the proximity to Tesla’s AI training cluster Cortex 1 and 2, both located at Giga Texas and now totaling over 230,000 H100 equivalent GPUs, means the Optimus software stack and the factory producing the hardware will share the same campus. Tesla’s Q1 report also confirmed completion of the AI5 chip tape out in April, the inference processor designed specifically to power Optimus units in the field.
As Teslarati reported, the Texas facility is intended to house Optimus V4 production at full scale. Musk told the World Economic Forum in January that Tesla plans to sell Optimus to the public by end of 2027 at a price between $20,000 and $30,000, stating, “I think everyone on earth is going to have one and want one.” He has previously pegged long term demand for general purpose humanoid robots at over 20 billion units globally, citing both consumer and industrial use cases.
Investor's Corner
Tesla (TSLA) Q1 2026 earnings results: beat on EPS and revenues
Tesla (NASDAQ: TSLA) reported its earnings for the first quarter of 2026 on Wednesday afternoon. Here’s what the company reported compared to what Wall Street analysts expected.
The earnings results come after Tesla reported a miss on vehicle deliveries for the first quarter, delivering 358,023 vehicles and building 408,386 cars during the three-month span.
As Tesla transitions more toward AI and sees itself as less of a car company, expectations for deliveries will begin to become less of a central point in the consensus of how the quarter is perceived.
Nevertheless, Tesla is leaning on its strong foundation as a car company to carry forward its AI ambitions. The first quarter is a good ground layer for the rest of the year.
Tesla Q1 2026 Earnings Results
Tesla’s Earnings Results are as follows:
- Non-GAAP EPS –Â $0.41 Reported vs. $0.36 Expected
- Revenues –Â $22.387 billion vs. $22.35 billion Expected
- Free Cash Flow –Â $1.444 billion
- Profit –Â $4.72 billion
Tesla beat analyst expectations, so it will be interesting to see how the stock responds. IN the past, we’ve seen Tesla beat analyst expectations considerably, followed by a sharp drop in stock price.
On the same token, we’ve seen Tesla miss and the stock price go up the following trading session.
Tesla will hold its Q1 2026 Earnings Call in about 90 minutes at 5:30 p.m. on the East Coast. Remarks will be made by CEO Elon Musk and other executives, who will shed some light on the investor questions that we covered earlier this week.
