SpaceX sets stage for Starship booster’s first 33-engine static fire

SpaceX has set the stage for a record-breaking Starship booster static fire after the rocket completed a complex fueling test and launch rehearsal earlier this week.

On January 25th, a tower the size of a skyscraper activated a pair of giant mechanical arms to disassemble the largest rocket ever built. The arms carefully grabbed Starship using hard points under its flaps and lifted the 50-meter-tall second stage and spacecraft off of Super Heavy Booster 7. Nicknamed Mechazilla, the robot lowered the hundred-ton (~220,000+ lbs) vehicle hundreds of feet onto a waiting stand and eventually let go. On January 26th, SpaceX transported Ship 24 back to its Starbase, Texas factory for finishing touches.

Booster 7 remained installed on Starbase’s donut-shaped orbital launch mount, which uses clamps and umbilicals to hold Starship in place and power, fuel, and pressurize Super Heavy. In theory, the next time Booster 7 leaves that launch mount, it will do so under its own power. But first, SpaceX must ensure that that unprecedented power can be controlled (and survived).

This, unfortunately, is far from the first iteration of this story. SpaceX has been seemingly close to the milestone at many points over the last year and a half. In September 2021, for example, CEO Elon Musk reported that Super Heavy Booster 4 would attempt the first static fire on Starbase’s orbital launch mount later that month. Eleven months later, Super Heavy Booster 7 gave the OLM its inaugural static fire test – albeit with just one of its 33 engines.

In the months following that static fire, Booster 7 completed another single-engine test, a two-engine test, a seven-engine test, a fourteen-engine test, and a long-duration eleven-engine test. All of that slow and steady testing has been fairly successful and caused no major damage to the rocket or pad. But five months after it began, SpaceX has never ignited more than 14 – 42% – of Super Heavy’s 33 Raptor engines at once. That must change before SpaceX can gain enough confidence in Starship for (and convince the FAA to license) an orbital launch attempt.

During Super Heavy B7’s 14-engine static fire, the booster could have produced up to 3220 tons (7.1 million pounds) of thrust. When it ignites all 33 available engines for the first time, its maximum thrust could leap to 7590 tons (16.7 million pounds), beating the next most powerful rocket in history – the Soviet N1 – by nearly 60%. In other words, SpaceX will be attempting something unprecedented in rocketry. Success is far from guaranteed and the worst possible failure mode could almost entirely destroy Starship’s only finished orbital launch site, explaining SpaceX’s unusual caution.

On January 23rd, Ship 24 and Booster 7 completed Starship’s first full wet dress rehearsal (a fueling and launch rehearsal test) on the first try – an extremely impressive achievement for any rocket, let alone the largest in history. With that combined test out of the way, the only unprecedented test standing between Starship and its first orbital launch attempt is a 33-engine Super Heavy static fire.

To reduce risk, Ship 24 was removed from Booster 7. Back at the factory, SpaceX needs to close a few gaps left in its heat shield, and will likely also conduct careful inspections to ensure that the Starship is ready for flight. Unburdened of Ship 24, Booster 7 may finally be on the cusp of the most challenging ground test in Starship and SpaceX history. SpaceX has scheduled 12-hour road closures that could be used for that purpose as early as January 30th, 31st, and February 1st.

Those road closures could be used for Ship 25 static fire testing instead of or in addition to Booster 7. The Super Heavy is also missing an important hydraulic power unit (HPU) that was removed before the wet dress rehearsal. It’s unclear if static fire testing can be conducted without that HPU (one of two), why it was removed, or how long replacing it will take, adding more uncertainty. Nonetheless, it still appears that SpaceX is no more than a few weeks away from Starship’s first 33-engine static fire attempt.

Elon Musk will give ‘every kid in America’ a SpaceX share in 2027

Elon Musk said he is planning to give “every one of his SpaceX shares to every kid in America” in 2027, stating that “this will be the first of many.”

SpaceX went public earlier this year, and its stock price has been relatively stable since leveling off shortly after its IPO. Based on its current price, it’s a gift of just over $10 billion to children across the United States.

It appears to be closely related to President Donald Trump’s bank accounts for children, which were set up earlier this year as Trump Accounts.

Just hours earlier, Anthropic had announced the establishment of its Anthropic Public Benefit Fund, “a new wholly-owned entity dedicated entirely to public benefit.” Musk responded by stating he recommended “giving the shares directly to the public,” and that he would be doing it that way.

Just a little bit later, Musk said children across the U.S. would be getting a share from him:

There are roughly 70 million children, meaning someone under the age of 18, in the United States, according to the Federal Interagency Forum on Child and Family Statistics. Musk’s ownership of SpaceX stock shows he has around 849 million Class A shares of SpaceX stock, according to filings with the SEC.

Elon Musk reveals why Boring Co’s biggest East Coast project never happened

Elon Musk revealed in a post on X that “Permits were impossible to get,” explaining the fate of The Boring Company’s most ambitious East Coast proposal.

The comment responded to a query about what became of his July 20, 2017 announcement that he had “just received verbal govt approval” for an underground Hyperloop connecting New York City, Philadelphia, Baltimore, and Washington, D.C., capable of carrying passengers from the Big Apple to the Nation’s Capital in just 29 minutes.

The Boring Company receives verbal ‘approval’ to build NY to DC Hyperloop tunnel

The 2017 post, which envisioned city-center stations and multiple elevators in each city, sparked immediate scrutiny. Local and state officials in New York, Philadelphia, Baltimore, and D.C. said they had no knowledge of any approval. A White House spokesperson confirmed only “promising conversations” about the transformative infrastructure.

Musk clarified shortly after that there was “still a lot of work” to do for formal approvals.

Limited progress followed, as Maryland Governor Larry Hogan’s administration issued a conditional utility permit and supported work near Fort Meade. In 2018, Washington, D.C., granted a preliminary permit for site preparation and excavation on a vacant lot at 53 New York Ave. NE in the NoMa neighborhood, which The Boring Company said could become a station.

A draft environmental assessment for a D.C.-Baltimore segment was released in 2019. Yet, by April 2021, the company had removed the project from its website, and the Federal Highway Administration reported receiving no indication of further interest. Communication with Maryland officials had ceased.

The full corridor would have required coordination among the District of Columbia, Maryland, Pennsylvania, New York, the Federal Highway Administration, the Army Corps of Engineers, the National Park Service, and other agencies.

Environmental reviews under the National Environmental Policy Act, utility clearances, and approvals for novel infrastructure added to the overall complexity of the project and its approval.

Speculation on the permitting barriers centers around a few factors, but a multi-state, multi-level route involving unproven high-speed vacuum-tube technology inherently triggers exhaustive safety, environmental, and engineering reviews that can stretch for years, even for conventional projects.

There are also other elements, of course, like officials who may face political exposure if a privately funded, untested system encountered anything such as cost overruns, delays, or safety issues. On the outset of this project, there were limited things such as engineering plans or demonstrated technology maturity, which also added to the potential skepticism.

The East Coast vision for Boring Co., once framed as a privately funded revolution that could reshape Northeast travel, quietly ended without construction of the promised network. Musk’s recent statement frames the outcome as a regulatory impasse, unfortunate but not unexpected.

Tesla CEO Elon Musk reminds everyone about Roadster’s true meaning

Tesla CEO Elon Musk took to his social media platform X on Sunday to remind everyone that the Roadster’s true meaning is not about company growth or adding dollars to shareholders’ pockets. Sometimes, you just do things because you can.

Following the Roadster’s epic unveiling event last Thursday, skeptics and critics of the company or the project itself came out to say that the vehicle is a pointless project because it is not geared toward growing the company, delivering supreme margins for profitability, nor does it contribute to the big picture of Artificial/Super Intelligence.

But that’s just the thing: Roadster is not meant to be some shareholder dream; it’s meant to be a vehicle that people buy just because it is something awesome, unique, and the first of its kind.

Musk had to remind those who are skeptical about the Roadster’s importance to the company mission that while it is not a major contributor to Tesla’s long-term goals, it is something that is being built just because it can be:

“Optimus and Cybercab will be the vast majority of Tesla’s value. The only things that will scale to incredible size (K2 and beyond) economically are super intelligence, robots, solar power, and mass to space. And, of course, if you have the first two, the rest will follow. But Roadster is super cool, so we’re doing it anyway.”

Musk has said on many occasions that Optimus would be the project that would make up the vast majority of Tesla’s value in the coming years.

Robotics will be a major focus of Tesla over the coming years, especially as Musk believes Optimus will enable work to be optional for humans and will enable what he calls “High Universal Income.”

Cybercab will be a passive income opportunity for owners, Musk and Tesla have said for a very long time, as a fleet of self-driving vehicles will operate within a ride-hailing Robotaxi service that won’t require a human driver to be present.

Tesla investors are more than enthusiastic about the company’s future projects, at least from a general consensus perspective. However, it is important to note that the Roadster is a fun and cool project that pushes the boundaries of what people thought was possible for an automobile.

What we saw last week was the first true example of a flying car, and despite the backlash about how it might not contribute to Tesla’s grand ambitions, it’s okay to have fun sometimes, too.
