SpaceX has been unable to catch a break in the last few weeks and CEO Elon Musk says that a Starship Raptor engine test was delayed twice in one day by minor hardware bugs and damage caused by Hurricane Hanna.

Although it quickly devolved into a tropical storm and largely missed the southernmost tip of Texas, where SpaceX has built its Starship factory and test facilities, Hanna caused significant damage just a few dozen miles to the north. Above all else, the flooding caused by Hanna has by far been the worst part of the storm. Boca Chica managed to dodge the bulk of that element but was still hit by heavy rain that lasted for a day or two, drenching everything that wasn’t covered and nearly flooding the only access road.

According to Musk, an unspecified “connector” related to Starship SN5 or the pad supporting it was damaged by Hanna’s glancing encounter with SpaceX’s facilities. The connector was ultimately fixed around 7-8 pm CDT per unofficial webcasts showing technicians working around the rocket after they returned to the pad, but SpaceX’s test window technically closed at 8 pm CDT (01:00 UTC).

Nevertheless, SpaceX must have been able to work with local sheriffs to extend that road closure into the night, and – as promised by CEO Elon Musk – testing restarted around 9:30 pm CDT. About an hour and a half later, Starship SN5 appeared to make it all the way through a partial wet dress rehearsal before its Raptor engine test fire was aborted a second time. Based on four static fires completed by Starship SN4 in May 2020, the rocket could have been just a few minutes away from ignition.

According to Musk, Starship SN5’s fuel (methane) “spin valve” – presumably a valve that opens to allow methane gas to spin up Raptor’s fuel turbopump – failed to open when it was supposed to. To ensure Raptor’s health after three inactive weeks spent installed on Starship out in the elements, SpaceX likely planned what is known as a “spin prime” test directly prior to the static fire. If Raptor successfully spun up its turbopumps, SpaceX would proceed directly into static fire operations without having to detank Starship.

During SN5’s second July 27th static fire attempt, Raptor was unable to start that spin prime test, forcing SpaceX to stand down to diagnose and fix the problem. Musk says that SpaceX will attempt to static fire Starship SN5 again tomorrow (July 28th) – assuming the issue can be quickly rectified.

Musk further noted that some “odd…behavior” was observed in the hydraulic pump powering Raptor SN27’s thrust vector control (TVC). Used to steer a rocket engine, Raptor doesn’t technically need functioning TVC to perform a static fire test on the ground, but it’s an issue that will have to be completely fixed before Starship SN5 is allowed to attempt its first flight test. If July 28th finally sees SN5 successfully ignite its Raptor engine, there’s a chance – however slim – that SpaceX will be able to turn the Starship around for its first hop just a few days later.

Tesla CEO Elon Musk teases Optimus job that’s straight out of Robocop

“If somebody’s committed a crime, we might be able to provide a more humane form of containment of future crime. You now get a free Optimus, and it’s just going to follow you around and stop you from doing crime.”

Tesla CEO Elon Musk teased a potential job for the company’s Optimus robot last week that is straight out of the movie “Robocop.”

“Robocop” aimed to show a futuristic look at law enforcement in a Sci-fi thriller that was among the first iterations of how robots could be used for police work.

The 1987 film showcased an injured cop turning into an armed cyborg, and although Tesla’s Optimus won’t be a human-robot hybrid, Musk’s idea for the humanoid project is similar.

Musk said last week at the Annual Shareholder Meeting, where shareholders voted to approve his $1 trillion compensation plan, that Optimus could be the future of law enforcement, nearly revolutionizing the way criminals are prosecuted.

He hinted that Optimus could actually be used as a chaperone of sorts, arguing that it was a “more humane form of containment of future crime.” Musk said:

“If somebody’s committed a crime, we might be able to provide a more humane form of containment of future crime. You now get a free Optimus, and it’s just going to follow you around and stop you from doing crime. Other than that, you get to do anything; it’s just going to stop you from committing crime. That’s really it. You don’t have to put people in prisons and stuff. It’s pretty wild to think of all the possibilities, but I think it’s clearly the future.”

Musk’s overall idea for Optimus is to change the way people are able to exist, from those law-abiding citizens to others who have their run-ins with the law. Instead, the Tesla CEO believes there could be a different way to handle everything, including punishment.

It was not the only thing that Musk indicated could be changed significantly by the presence of humanoid robots, as he also said a universal basic income could be established with the help of products like Optimus.

Elon Musk teases huge merger: ‘Trending towards convergence’

“My companies are, surprisingly in some ways, trending towards convergence.”

Published

Elon Musk recently amplified the thoughts of Morgan Stanley analyst Adam Jonas, who had insight into the “Muskonomy” of his potentially interconnected ventures, something that was proposed at the recent Tesla Shareholder Meeting with xAI.

Musk’s words indicate a potential strategic fusion that could serve as a blueprint for future innovation–but it is dependent on a conglomeration between the many entities the CEO serves.

As Tesla grapples with scaling Optimus and preparing for its imminent production and the development of the Full Self-Driving suite, xAI’s computational edge could provide leverage for the millions of miles of data the company accumulates, providing a more stable and accurate development strategy for the autonomous and AI efforts it has put its chips all in on.

After Tesla Shareholders voted to deny Tesla and xAI’s potential financial partnership through an investment, Jonas said it was an issue that would have to be revisited due to its importance.

xAI has the opportunity to provide an incredible strategic and financial bolstering to Tesla, especially with how important a role data plays in the development of the company’s biggest products.

Jonas wrote in a note to investors:

“They’re gonna have to revisit this. We don’t think investors understand just how important xAI is to Tesla and the broader Muskonomy. Tesla’s relationship with xAI (financially and strategically) is deterministic to the long-term success of Tesla due in part to the natural synergies of data, software, hardware, and manufacturing in recursive loops. The values (and value systems) of both Tesla and xAI are endowed by the values of their shared creator. We believe this co-determination becomes more obvious in the next phases of physical AI/ autonomy for Tesla in the year ahead.”

Musk said, in response to Jonas’ note, that his companies are “surprisingly in some ways, trending toward convergence.”

Mergers and shared ecosystems between companies are not new moves out of Musk’s playbook, as it has been done in the past, especially with Tesla acquiring other entities.

It did it with SolarCity in 2016 and with Maxwell Technologies in 2019. Investments between Musk companies have occurred before, too, as SpaceX dumped $2 billion into xAI last July.

He’s also said on several occasions that he could eventually bring everything together into some sort of single entity. In July 2024, he said:

“I’m not opposed to the idea in principle, but I’m not sure there is a pragmatic or legal way to merge them. There is also value in equity incentives of people at the companies being tied to that company’s accomplishments.”

This point is especially relevant now with Musk’s recently approved compensation package.

He also said in June, during an interview with CNBC , that “It’s not out of the question” for xAI to merge with Tesla, but it would have to be approved by shareholders. Just a few days later, he said he would not support xAI merging with Tesla; however, he put it in investors’ hands.

It’s more than just a deal; it’s symbiotic. Musk being at the helm of various companies, all intertwined with one another, helps foster recursive innovation. Despite these advantages, there are still a handful of things to consider, especially from a regulatory perspective.

However, it is not competition; it’s convergence. In Musk’s universe, especially from a business sense, mergers are not endpoints, but instead launchpads for ambitions that aim to take each company from Earth to lands beyond our atmosphere.

Tesla makes Elon Musk’s new compensation package official

This is an important thing to note, as much of the media coverage regarding Musk’s pay package seems to indicate that the company and the shareholders are simply giving the CEO the money. He has to come through on each of these tranches to unlock the $1 trillion.

Tesla has made CEO Elon Musk’s new compensation package official, as it filed a Form 4 with the Securities and Exchange Commission (SEC) on Monday.

The package officially gives Musk the opportunity to acquire over 423 million shares of Tesla stock (NASDAQ: TSLA), dependent on his ability to achieve twelve performance-based tranches that will bring growth to the company and its shareholders.

Tesla (TSLA) shareholders officially approve Elon Musk’s 2025 performance award

Musk’s new compensation package was approved by investors last Thursday at the company’s Annual Shareholder Meeting, as over 75 percent of voters supported the CEO’s new plan, which could be valued at over $1 trillion if he is able to come through on all twelve tranches.

The twelve tranches include growth goals related to vehicle deliveries, the Optimus humanoid robot project, and Tesla’s valuation. If Musk is able to achieve each tranche, he would help Tesla achieve an over $8 trillion market cap.

The 12 tranches include:

  1. $2 trillion market cap + Deliver 20 million Tesla vehicles cumulatively
  2. $2.5 trillion market cap + Reach 10 million active Full Self-Driving (FSD) subscriptions
  3. $3 trillion market cap + Deliver 1 million Optimus humanoid robots
  4. $3.5 trillion market cap + Operate 1 million Robotaxis commercially
  5. $4 trillion market cap + Hit $50 billion in adjusted EBITDA (earnings before interest, taxes, etc.)
  6. $4.5 trillion market cap + Hit $80 billion in adjusted EBITDA
  7. $5 trillion market cap + Hit $130 billion in adjusted EBITDA
  8. $5.5 trillion market cap + Hit $210 billion in adjusted EBITDA
  9. $6 trillion market cap + Hit $300 billion in adjusted EBITDA
  10. $6.5 trillion market cap + Hit $400 billion in adjusted EBITDA
  11. $7.5 trillion market cap + Hit $400 billion in adjusted EBITDA for four straight quarters in a row
  12. $8.5 trillion market cap + Hit $400 billion in adjusted EBITDA for four straight quarters in a row

Achieving the twelve levels of the new compensation package would also give Musk what he’s really after: a larger ownership share in Tesla, which would help him achieve more control, something he feels is necessary for the rollout of the Optimus robot “army.”

Musk does not earn a dime if he does not achieve any of the tranches above.

This is an important thing to note, as much of the media coverage regarding Musk’s pay package seems to indicate that the company and the shareholders are simply giving the CEO the money. He has to come through on each of these tranches to unlock the $1 trillion.
