SpaceX has successfully completed a static fire of its newest Falcon Heavy center core, a sign that the most challenging hardware is firmly on track for a late-June launch target.

Currently penciled in for June 22nd, Falcon Heavy’s third launch is of great interest to both SpaceX and its customer, the US Air Force. Most of the two-dozen payloads manifested on the mission are admittedly unaffiliated with the US military. However, the rideshare – known as Space Test Program 2 (STP-2) – was acquired by the USAF for the branch to closely evaluate and certify SpaceX’s Falcon Heavy rocket for critical military launches. The potential upsides of a successful demonstration and evaluation are numerous for both entities and would likely trigger additional positive offshoots.

The Center Core experience

Beyond the general contractual aspects of STP-2, the mission is significant because it will use the third Falcon Heavy center core and second Block 5 variant to be built and launched by SpaceX. Of the technical issues that complicated and delayed SpaceX’s Falcon Heavy development, most can probably be traced back to the rocket’s center core, practically a clean-slate redesign relative to a ‘normal’ Falcon 9 booster.

Most of that work centered around the extreme mechanical loads the center core would have to survive when pulling or being pulled by Falcon Heavy’s two side boosters. Not only would the center core have to survive at least two times as much stress as a Falcon 9 booster, but that stress would be exerted in ways that Falcon 9 boosters simply weren’t meant to experience, let alone survive. After years of work, SpaceX arrived at a design that dumped almost all of that added complexity squarely on the center core and the center core alone. The side boosters would need to use nosecones instead of interstages and have custom attachment points installed on their octawebs and noses, but they would otherwise be unmodified Falcon 9 boosters.

On top of that, SpaceX’s Falcon upper stage and payload fairing would require no major modifications to support Falcon Heavy missions. On the opposite hand, the center core would require extensive rework to safely survive the trials of launch, let alone do so in a fashion compatible with booster recovery and reuse. Per the landing photos above, it’s difficult to tell a Falcon Heavy center core apart from a normal Falcon 9 booster, but the small visible changes are just the tips of several icebergs. Aside from a slight indication that the center core’s aluminum alloy tank walls are significantly thicker (they are), center cores feature a variety of unique mechanisms on their octawebs and interstages. All are involved in the tasks of locking all three boosters together, transferring side booster thrust to the center core, and mechanically separating the side boosters from the center core a few minutes after launch.

Underneath those mechanistic protuberances are the structural optimizations needed for a center core to survive the ordeal of launch. In short, to solve for those new loads, SpaceX wound up building a new rocket. Designing and building a new rocket – especially one as complex as Falcon Heavy’s center core – is immensely challenging, expensive, and time-consuming, particularly for the first few built. Like most complex products, building the first two Falcon Heavy center cores was probably no different. To make things worse, boosters 1 and 2 were based on totally different versions of Falcon 9 (Block 3 vs. Block 5), requiring even more work to further redesign and requalify the modified rocket.

This is where the center core assigned to Falcon Heavy Flight 3 and pictured above comes into play. Built just a few months apart from B1055, the first finished Falcon Heavy Block 5 center core, the newest center core – likely B1057 – is also the first to be built with the same design and manufacturing processes used on its predecessor. In other words, SpaceX can at long last begin serial production of Falcon Heavy center cores, allowing its engineering, production, test, and launch staff to finally get far more accustomed to the unique hardware.

Given Falcon Heavy’s healthy and growing manifest of 5-6 launches, SpaceX will probably need to build several additional Block 5 center cores over the next several years, hopefully resulting in a more refined flow for production, testing, and refurbishment. B1057 will be an excellent candidate for the first reused Falcon Heavy center core thanks to STP-2’s lightweight nature and an extremely gentle landing trajectory. With respect to Flight 3’s schedule, Crew Dragon’s April 20th explosion means that Falcon Heavy will have Pad 39A all to itself for many months to come. Truly the epitome of bittersweet, no doubt, but it does improve the odds that Falcon Heavy’s June 22nd STP-2 launch target will hold.

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 (TSLA) Q1 2026 earnings results: beat on EPS and revenues

Published

on

Credit: Tesla

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 – $0.41 Reported vs. $0.36 Expected
  • Revenues – $22.387 billion vs. $22.35 billion Expected
  • Free Cash Flow – $1.444 billion
  • Profit – $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.
