SpaceX is about to stack Starship on a Super Heavy booster for the first time
After a slight delay, CEO Elon Musk says that SpaceX is now on track to stack a complete Starship prototype on top of a Super Heavy booster for the first time ever as early as Friday morning.
In the latest stage of SpaceX’s continually impressive “Starbase Surge,” the company rolled the first orbital-class Starship prototype’s aft tank section from its birthplace in the factory “midbay” to a much larger “high bay” around noon on August 3rd. Mere hours later, Elon Musk revealed that SpaceX had fitted the Starship with a full six Raptors – a first for any Starship prototype, though Super Heavy Booster 4 technically beat it to the punch with the installation of a staggering 29 Raptor engines hours prior.
The rocket’s conical nose section joined it in the high bay later that evening and SpaceX wasted no time stacking and welding the two Starship halves together early on August 4th, effectively completing the basic structure of Ship 20 (S20). After a day of final integration work, Starship S20 left the high bay around dawn on August 5th and took to the highway for a brief trip from SpaceX’s Boca Chica factory to launch and testing facilities just a mile and a half to the east.
On August 3rd, Super Heavy Booster 4 – fitted with 29 functional Raptor engines – made the same trip from build site to launch pad, where it sat on the transporter overnight. On August 4th, with slightly calmer winds, SpaceX installed the immense ~69m (~225 ft) tall rocket booster on an orbital launch mount that itself had only been installed less than a week prior.
Ship 20 arrived at the orbital launch site a few hours after heading out and was eventually moved directly beside Booster 4 and the orbital launch mount and attached to the largest crane in SpaceX’s arsenal. After several hours sitting in one place, SpaceX announced over a sitewide loudspeaker system that all further stacking operations had been called off for the day, which Musk later confirmed on Twitter was due to wind conditions at the launch site.
Had the weather cooperated, SpaceX’s plan was to install Starship S20 on top of Super Heavy Booster 4, a feat that would have marked the first time a two-stage Starship rocket has ever been fully assembled. Due to the current setup’s temporary nature, SpaceX must complete that stacking process with a vast crawler crane – the same crane used to fully assemble a ~145m (~475 ft) tall Starship integration tower visible directly behind the rocket.
Sitting on top of the fairly tall orbital launch mount, Starship S20 and Super Heavy Booster 4 will stand about as tall as that 145m launch tower, though the booster and ship itself are expected to be just shy of 120m (~390 ft) from tip to Raptor tail. Once stacked, the vehicle will be the tallest rocket assembled in the history of spaceflight.

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.
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.
