SpaceX has returned its newest Super Heavy to Starbase’s orbital launch site (OLS) after rapidly repairing damage the booster suffered during its first round of testing.

Super Heavy Booster 7 (B7) left the High Bay it was assembled in for the first time on March 31st and rolled a few miles down the road to nearby Starship launch and test facilities on a set of self-propelled mobile transporters (SPMTs). On April 2nd, the roughly 67-meter-tall (~220 ft; 69m w/ Raptors) rocket was installed on top of Starbase’s lone orbital launch mount (OLM), setting the stage for crucial qualification testing.

The start of that process was exceptionally successful. On April 4th, after a smooth launch mount installation, SpaceX quickly filled Booster 7’s propellant tanks with a relatively benign cryogenic fluid (liquid nitrogen, liquid oxygen, or both) to simulate the thermal and mechanical characteristics of real flammable propellant. Despite the fact that the test marked the first time SpaceX had fully filled a Super Heavy prototype’s tanks, Booster 7 sailed through the ‘cryoproof’ without any obvious issue.

On April 8th, SpaceX moved Super Heavy B7 from the orbital launch mount to a structural test stand that had been installed and modified just a few hundred feet away in the weeks prior. This is where Booster 7’s near-perfect start to qualification testing took a bit of a turn. Booster 7 is only the third full-size Super Heavy prototype SpaceX has tested since July 2021. Like Booster 3 and Booster 4 before it, Booster 7 features some major design changes that ultimately make the prototype a pathfinder, necessitating extensive qualification testing.

To name just a few of the changes, Super Heavy B7 is the first booster fitted with a 33-engine puck and the first finished Starship prototype of any kind designed to use new Raptor V2 engines. With all 33 engines installed and operating a full thrust, Booster 7’s entire structure – and its aft thrust section especially – would be subjected to around 40% more thrust and stress than Booster 4, which indirectly completed structural testing with the help of a sacrificial test tank. Beyond differences in thrust and mechanical stress, Booster 7 is also the first Super Heavy to reach the test stand with secondary ‘header’ tanks meant to store landing propellant.

It’s unclear if those header tanks were fully filled and drained during Booster 7’s cryoproof, but they would not be quite as cooperative during a different kind of cryogenic testing on the structural test stand. The stand SpaceX modified specifically for Super Heavy B7 was outfitted with 13 hydraulic rams to simulate the full thrust of the booster’s central Raptor V2 engines – up to almost 3000 tons (~6.6M lbf) compared to Booster 4’s ~1700 tons (~3.7M lbf) with a smaller cluster of nine engines.

Implosion at the Structural Test Stand

After a few false starts and minor tests on the stand, Booster 7 finally managed some significant testing on April 14th. Judging by the rhythmic shattering of ice that built up on Super Heavy’s tanks, the test stand was able to simulate the thrust of Raptors to some degree and subject the booster to major mechanical stress that was felt from tip to tail. Within a few days, Booster 7 was removed from the test stand and returned to the high bay on April 18th. Around April 21st or 22nd, an image was leaked showing extensive damage inside Booster 7, confirming that the Super Heavy’s test campaign had been forced to end prematurely.

Right away, the damage shown in the photo hinted at an operational failure, meaning that mistakes made by the rocket’s operators may have been more to blame than a possible design flaw. The photo shows a short portion of B7’s liquid methane (LCH4) transfer tube that runs through the booster’s new liquid oxygen (LOx) header tank, which itself sits inside Super Heavy’s main LOx tank at the aft end of the rocket – a tube inside a small tank inside a large tank, in other words. Super Heavy’s LCH4 transfer tube generally does what it says, allowing methane to safely fly down through the main LOx tank and fuel up to 33 Raptor engines. At full thrust, that tube would need to supply around 20 tons (~45,000 lb) of methane per second.

However, on top of merely transferring methane through the oxygen tank, Booster 7 introduced a design change that allows some or all of that tube to change functions and become a header tank mid-flight. That would require a system of valves that could seal off the main LCH4 tank once it was emptied, turning the transfer tube into a sort of giant steel straw filled with enough LCH4 to fuel Super Heavy’s boost-back and landing burns.

The damaged transfer tube in the leaked photo of Booster 7 doesn’t look that unlike what one might expect to see if they sucked through one end of a straw while blocking the other end, collapsing the center. Translated to the scale of Super Heavy, after an otherwise successful day of structural testing, SpaceX operators may have accidentally closed or opened the wrong valves while draining the booster’s transfer tube of liquid oxygen or nitrogen. As the heavy liquid drained from the tube, a lack of pressure equalization could have quickly drawn a vacuum and caused the tube to implode.

The

On April 29th, a SpaceX fan turned analyst published an analysis that convincingly pinpointed the moment Booster 7’s transfer tube collapsed. Simultaneously, because it showed that the transfer tube likely imploded during detanking, the analysis more or less confirmed the above speculation that the failure had been caused by a degree of operator error or poor test design. Of course, it’s possible that a hardware or software design flaw contributed to or caused the anomaly or that something like a pressure differential in the LOx header tank and LCH4 header tube could also explain the damage, but the accidental formation of a vacuum during detanking is arguably the simplest (obvious) explanation.

After the image of the internal damage leaked, the immediate consensus among fans and close followers was that Booster 7 was beyond repair. Instead, SpaceX appears to have proven those assumptions wrong and somehow managed to repair the upgraded Super Heavy to the point that it was worth testing again less than three weeks after returning to the high bay. On May 6th, B7 was rolled back to the launch site and installed, for the second time, on the orbital launch mount.

Prior to the failure, the general expectation was that SpaceX would begin installing Raptor V2 engines as soon as Booster 7 passed structural testing. It remains to be seen if SpaceX wants to repeat Booster 7’s cryoproof or structural testing to ensure that its quick repairs did the job before proceeding into static fire testing as previously planned. Nonetheless, hope lives on for the Super Heavy prototype and new test windows have been scheduled from 10am to 10pm on May 9th, 10th, and 11th.

Tesla Earnings: financial expectations and what we should to hear about

In terms of discussions, Tesla earnings calls are usually a great time to get some clarification on the company’s outlook for its current and future projects.

Tesla (NASDAQ: TSLA) will report its earnings for the first quarter of 2026 this evening after the market closes, and analysts have already put out their expectations from a financial standpoint for the company’s first three months of the year.

Additionally, there will be plenty of things that will be discussed, including the recent expansion of the Robotaxi program, the Roadster unveiling, and Full Self-Driving (Supervised) approvals across the globe.

Financial Expectations

Wall Street consensus expectations put Tesla’s Earnings Per Share (EPS) at $0.36, while revenues are expected to come in around $22.35 billion.

This would compare to an EPS of $0.27 and $19.34 billion compared to Tesla’s Q1 2025. Last quarter, EPS came in at $0.50 on $29.4 billion of revenue.

Tesla beat analyst expectations last quarter, but the next trading day, the stock fell nearly 3.5 percent. We never quite can gauge how the market will respond to Tesla’s earnings; we’ve seen shares rise on a miss and fall on a beat.

It really goes on the news, and investor consensus, it seems.

What to Expect

In terms of discussions, Tesla earnings calls are usually a great time to get some clarification on the company’s outlook for its current and future projects. Right now, the big focus of investors is the Robotaxi program, the Roadster unveiling, and what the outlook for Full Self-Driving’s expansion throughout Europe and the rest of the world looks like.

Robotaxi

Tesla just recently expanded its unsupervised Robotaxi program to Dallas and Houston, joining Austin as the first cities in the U.S. to have access to the company’s ride-hailing suite.

Tesla expands Unsupervised Robotaxi service to two new cities

Some saw this move as a quick effort to turn attention away from a delivery miss and an anticipated miss on earnings. However, we’ve seen Tesla be more than deliberate with its expansion of the Robotaxi suite, so it’s hard to believe the company would make this move if it were not truly ready to do so.

The company is also working to expand its U.S. ride-hailing service outside of Texas and California, and recently filed paperwork to build a Robotaxi-exclusive Supercharger stall.

Expansion is planned for Florida, Nevada, and Arizona at some point this year, with more states to follow.

Roadster Unveiling

The Roadster unveiling was slated for April 1, and then pushed back (once again) to “probably late April,” according to Elon Musk.

It does not appear that the Roadster unveiling will happen within that time frame, at least not to our knowledge. Nobody has received media or press invites for a Roadster unveiling, and given the lofty expectations set for the vehicle by Musk and Co., it seems like something they’d want to show off to the public.

Tesla Roadster unveiling set for this month: what to expect

The Roadster has become a truly frustrating project for Tesla and its fans; evidently, there is something that is not up to the expectations Musk and others have. Meanwhile, fans are essentially waiting for something that is six years late.

At this point, also given the company’s focus on autonomy, it almost seems more worth it to just cancel it, remove any and all timelines and expectations, and surprise people with something crazy down the line, maybe in two or three years. There should be no talk of it.

Full Self-Driving Global Expansion

We expect Musk and Co. to shed some details on where it stands with other European government bodies, as it recently was able to roll out FSD (Supervised) to customers in the Netherlands.

Tesla Full Self-Driving gets first-ever European approval

Spain is also working with Tesla to assess FSD’s viability as a publicly available option for owners.

With that being said, there should be some additional information for investors as they listen to the call; no talk of it would be a pretty big letdown.

Optimus

There will likely be a date set for the Gen 3 Optimus unveiling, and we’re hopeful Tesla can keep that date set in stone and meet it. Not reaching timelines is a relatively minor issue, but a company can only do this for so long before its fans and investors start to lose trust and disregard any talk about dates.

It seems this is happening already.

Optimus has been pegged as Tesla’s big money maker for the future. The goals and expectations are high, but it is a privilege to have that sort of pressure when investors know the company’s capability.

Tesla just unlocked sales to 50,000+ government agencies

It marks a significant step in expanding Tesla’s presence in the public sector, where procurement processes have traditionally slowed electric vehicle adoption.

Tesla just unlocked sales to over 50,000 government agencies by entering a new agreement with Sourcewell, a purchasing cooperative.

Tesla entered a new master purchasing agreement with Sourcewell, the largest government purchasing cooperative in the U.S. This will enable streamlined sales of its EVs to more than 50,000 U.S. public entities. Tesla entered Designated Contract 0813525-TES, and the agreement covers Model 3, Model Y, and Cybertruck, and potentially other vehicles the company could release.

It marks a significant step in expanding Tesla’s presence in the public sector, where procurement processes have traditionally slowed electric vehicle adoption.

The deal allows eligible agencies, including cities, school districts, state governments, and higher-education institutions, to purchase Tesla vehicles directly through Sourcewell without conducting their own lengthy competitive bidding or request-for-proposal (RFP) processes.

Pricing is pre-negotiated and capped, providing transparency and predictability. Agencies simply register for a Sourcewell account online or by phone and place orders under the existing contract. This cooperative model aggregates demand across thousands of members, reducing administrative costs and time while ensuring compliance with public procurement rules.

For Tesla, the agreement removes major barriers to government fleet sales. Public-sector procurement cycles often stretch 12 to 18 months due to bidding requirements and committee reviews.

Tesla buyers in the U.S. military can get $1,000 off Cybertruck purchases

By securing the master contract, Tesla gains immediate, simplified access to a massive customer base that previously faced friction in adopting EVs. The company highlighted in its announcement that the partnership will help these 50,000-plus agencies “save thousands of $$$ in operating costs for their vehicle fleet over time” through lower maintenance, energy efficiency, and the elimination of tailpipe emissions.

The initial four-year term runs through November 13, 2029, with options for up to three one-year extensions, offering long-term stability for both parties.

Sourcewell’s role is central to execution. As a cooperative purchasing organization, it negotiates and manages vendor contracts on behalf of its members, then makes them available nationwide. Participating entities contact Tesla’s dedicated fleet team or Sourcewell representatives to complete purchases, bypassing redundant paperwork.

This structure accelerates fleet electrification while maintaining fiscal accountability—agencies receive pre-vetted pricing and terms without reinventing the wheel for each vehicle order.

The partnership positions Tesla to capture a larger share of the public fleet market, where total cost of ownership often favors electric vehicles once procurement hurdles are removed.

For government buyers, it translates to faster deployment of sustainable fleets, reduced long-term expenses, and alignment with environmental mandates. As more agencies transition, the contract could contribute to broader EV infrastructure growth and taxpayer savings across the country.

How much of SpaceX will Elon Musk own after IPO will surprise you

SpaceX’s IPO filing confirms Musk will maintain his voting power to make key decisions for the company.

Elon Musk will retain dominant voting control of SpaceX after it goes public, according to the company’s IPO prospectus that was filed with the SEC. The filing reveals a dual-class equity structure giving Class B shareholders 10 votes each, concentrating power with Musk and a handful of other insiders, while Class A shares sold to public investors carry one vote.

Musk holds approximately 42% of SpaceX’s equity and controls roughly 79% of its votes through super-voting shares. He will simultaneously serve as CEO, CTO, and chairman of the nine-member board after the listing. Beyond that, the filing includes provisions that may limit shareholders’ influence over board elections and legal actions, forcing disputes into arbitration and restricting where they can be brought.

The case for Musk holding this level of control is grounded in SpaceX’s actual history. The company’s most important bets, from reusable rockets to a global satellite internet constellation, were decisions that ran against conventional aerospace thinking and would likely have faced resistance from a board accountable to investor gains. Fully reusable rockets were considered economically irrational by established industry players for years. Starlink, which now generates over $4 billion in annual operating profit, was widely dismissed as financially unviable when it was proposed. The argument for concentrated founder control seems straightforward, and the decisions that built SpaceX into what it is today required someone willing to ignore consensus and absorb years of losses.

SpaceX files confidentially for IPO that will rewrite the record books

For context, Musk’s position is significantly more dominant than Zuckerberg’s at Meta. The comparison with Tesla is also worth noting. When Tesla did its IPO in 2010, it did not issue dual-class shares. Musk has only recently pushed for enhanced voting protection, proposing at least 25% control at Tesla in 2024 after selling shares to fund his Twitter acquisition left him with around 13%.

SpaceX has clearly learned from that experience and structured the IPO differently by planning to allocate up to 30% of shares to retail investors, roughly three times the typical norm for a large offering. The roadshow is expected to begin the week of June 8, with a Nasdaq listing rumored to be a $1.75 trillion valuation and a $75 billion raise.
