SpaceX Falcon Heavy completes successful rehearsal, static fire pushed back due to bug in launch pad hardware
More than a decade after its 2005 public conception, SpaceX is closer than ever to the first launch Falcon Heavy, the company’s newest rocket. Earlier this afternoon, the vehicle was aiming for its first static fire test, in which all 27 of its engines would be ignited (nearly) simultaneously in order to test procedures and the rocket itself. This attempt was sadly scrubbed, but only after the vehicle apparently completed a successful wet dress rehearsal, which saw Falcon Heavy fully loaded with propellant. According to Orlando’s News 13, the attempt was scrubbed only after one of eight hold-down clamps showed signs of bugs.

While Falcon Heavy is not explicitly critical for SpaceX’s near-term launch business and its loftier future goals, the development and operation of such a massive launch vehicle will likely serve as a strong foundation as the company transitions more aggressively into the design, engineering, and manufacture of its still-larger BFR series of rocket boosters and upper stages. Falcon Heavy stands approximately as tall as Falcon 9 at around 70 m (230 ft), but features three times the thrust and a little less than three times the weight of SpaceX’s workhorse rocket. With 27 Merlin 1D engines to Falcon 9’s namesake nine, Falcon Heavy’s 22,800 kN (5,000,000 lbf) of thrust is a nearly inconceivably amount of power, equivalent to twenty Airbus A380 passenger jets at full throttle.
Why is Falcon Heavy important?
If SpaceX manages to pull off Falcon Heavy as a successful and reliable launch vehicle on the order of its reasonably successful Falcon 9, BFR may well be an easier vehicle to develop and operate, thanks to its single-core design. As Musk himself has discussed over the last year or so, the problem of safely and reliably distributing the thrust of Heavy’s side cores to the center core was unexpectedly difficult, as were the issues of igniting all 27 Merlin 1Ds and safely separating the side cores while in flight. Ultimately, the payload improvement (while in a fully reusable mode of operation) was quite small, particularly for the geostationary missions that make up essentially all prospective Falcon Heavy customer missions.
The additional complexity of recovery and refurbishing three separate Falcon 9 boosters almost simultaneously likely serves to only worsen the vehicle’s potential payoff, although the upcoming Block 5 iteration of Falcon 9 may partially improve the vehicle’s ease of operation. If Block 5 is indeed as reusable as SpaceX intends to make it, then a handful of Block 5 Falcon Heavy vehicles could presumably maintain a decent launch cadence for the vehicle without requiring costly and time-consuming shipping all over the continental US.

Nevertheless, the (hopefully successful) experience that will follow the launch and recovery operation of a super heavy-lift launch vehicle (SHLV) with ~30 first stage engines will be invaluable for SpaceX’s interplanetary goals. While BFR will be free of the complexity Falcon Heavy’s triple-core first stage added, it is still a massive vehicle that absolutely dwarfs anything SpaceX has attempted before. BFR in its 2017 iteration would mass around three times that of Falcon Heavy and feature 30 Raptor engines capable of approximately 53,000 kN (12,000,000 lbf) of thrust at liftoff, around 2.5x that of Heavy. Many, many other features mean that BFR and particularly BFS will be extraordinarily difficult to realize: BFS alone will be treading into truly unprecedented areas of spaceflight with the scale, longevity, and reusability it is intended to achieve while comfortably ferrying dozens of astronauts to and from Mars and the Moon.
However, the scale of BFR is equivalent to that of the famous Saturn V rocket that took astronauts to the Moon in the 1960s and 70s. In other words, while still dumbfoundingly massive and unprecedented in the modern era, rockets at the scale of BFR do in fact have a precedent of success, which lends the effort considerable plausibility, at least at proof-of-concept level. As of September 2017, Elon Musk suggested that SpaceX was aiming to begin construction of the first BFS (Big ____ Spaceship) by the end of Q2 2018, a truly Muskian deadline that probably wont hold. Still, if construction of the first prototype begins at any point in 2018, it will bode well for SpaceX’s aggressive timelines.

In the meantime, BFR’s precursor Falcon Heavy has effectively completed its first wet dress rehearsal, although the static fire attempt was scrubbed for the day. This is understandable for such a complex and untested vehicle, especially after SpaceX’s exceptionally quick modifications to Pad 39A. While unofficial, word is that an issue with one of the Transport/Erector/Launcher’s (TEL) eight separate launch clamps caused the scrub. Those launch clamps ensure that the massive vehicle would stay put during a static fire, and the status of those clamps would be especially important during such an unusually long static fire of such a powerful rocket.
Stay tuned for updates on SpaceX’s upcoming launches and Falcon Heavy’s next static fire attempt, likely within the next several days. The vehicle’s inaugural launch date is effectively up in the air until the static fire has been successfully completed, but as of yesterday SpaceX was understood to be targeting January 26th. Delays are to be expected.

SpaceX CEO Elon Musk recently confronted worries about orbital data centers and launching satellites in mass quantities in space, as some voiced concerns about crowding.
Musk’s SpaceX plans to combat the issue of needing data centers by launching them into space instead of taking up valuable real estate on Earth. It has been a major point of SpaceX’s future, including its looming IPO, which could be the largest ever.
In a recent interview filmed at SpaceX’s Starlink terminal factory in Bastrop, Texas, Elon Musk directly addressed concerns that deploying large numbers of AI satellites for orbital data centers could crowd Earth’s orbit. His message was straightforward and reassuring: space is vast beyond human intuition.
“Space is really big,” Musk said. “It’s not like space is gonna get crowded. Space is enormous. If you actually look at it relative to the Earth, the satellites are so tiny you can’t even see them.” He emphasized that even zooming in makes a satellite appear large, but from a planetary perspective, they are minuscule specks.

Musk pointed to SpaceX’s real-world experience operating roughly 10,000 Starlink satellites as evidence that large constellations can be managed safely. “We’ve got a pretty good idea of how to operate just really large constellations and do it safely,” he noted. SpaceX remains the only operator with meaningful experience at this scale, giving the company unique insight into tight orbital packing without compromising safety
The discussion highlighted SpaceX’s plans for “AI1” satellites—essentially orbiting racks of AI compute powered by massive solar arrays and cooled via radiative panels in space’s vacuum.
These satellites leverage proven Starlink V3 technology, making them simpler to design than communications satellites. A first-generation unit targets around 150 kW peak power, with a 70-meter wingspan for solar panels and radiators. Laser links will connect them to each other and the Starlink network, delivering low-latency access (on the order of a few milliseconds from low-Earth orbit).

Musk framed orbital data centers as a practical solution to Earth’s constraints on AI growth. Ground-based facilities face power shortages, water demands for cooling, and grid limitations. In space, constant sunlight (no day-night cycle), vacuum radiative cooling, and abundant solar energy offer clear advantages.
Production will ramp up at an expanded “Gigasat” factory in Bastrop, with solar manufacturing already underway and full AI satellite output expected at reasonable volume by the end of 2027. Starship’s rapid, high-volume launch capability, aiming for multiple flights per hour, will make massive deployment feasible.
Critics sometimes raise risks like space debris or Kessler syndrome, but Musk’s response underscores scale: even a million satellites would represent an imperceptible fraction of available orbital volume when viewed against Earth’s size. SpaceX’s automated collision avoidance and deorbiting designs for Starlink further mitigate concerns.
This vision ties into broader ambitions. Musk sees orbital AI compute as a step toward harnessing more of the Sun’s energy, advancing humanity on the Kardashev scale from a Type 0 civilization toward Type 1 and eventually Type 2. By moving power-hungry data centers off-planet, SpaceX aims to unlock orders-of-magnitude more compute while preserving Earth’s resources.
Musk’s comments should ease public anxiety. With proven operational expertise, incremental engineering, and the immensity of space itself, orbital data centers represent not overcrowding, but smart expansion into the final frontier.
The Ontario Teachers’ Pension Plan (OTPP) stands to reap one of the most extraordinary returns in pension fund history thanks to a bold 2019 investment in SpaceX.
According to a recent report from The Globe and Mail, the Toronto-based fund invested roughly $300 million CAD (~$220 million USD at the time) in Elon Musk’s space company as its inaugural deal through the Teachers’ Innovation Platform.
At SpaceX’s anticipated $1.75 trillion IPO valuation, set for a mid-June debut on Nasdaq under ticker $SPCX, that stake could now be worth up to $11.6 billion USD. This would represent a roughly 50x return and easily become OTPP’s most successful single investment ever.
The fund manages $279 billion in assets for approximately 346,000 working and retired teachers in Ontario, potentially delivering an average boost of around $33,500 per member if fully realized.
SpaceX has filed its S-1 and plans to price shares at $135 each, aiming to raise a record $75 billion in what would be the largest IPO in history, surpassing Saudi Aramco. The company reported $18.67 billion in revenue for 2025, driven primarily by Starlink satellite internet growth and NASA contracts, though it continues to post significant losses tied to ambitious R&D in Starship and AI initiatives.
Important pieces moving forward include:
- Starlink Expansion: The satellite broadband service is scaling rapidly, targeting global connectivity, especially in underserved rural and remote areas. This segment offers massive recurring revenue potential as numbers climb.
- Starship and Reusability Leadership: SpaceX’s fully reusable Starship aims to slash launch costs dramatically, enabling frequent missions, Mars ambitions, and lucrative government/defense contracts. Success here could unlock exponential growth.
- AI and Diversification: Recent moves, including ties to xAI, position SpaceX in high-growth AI infrastructure, broadening beyond traditional aerospace.
- Validation Scrutiny: While the $1.75 trillion target excites investors, analysts like Morningstar value the company closer to $780 billion, citing high multiples (around 90x trailing revenue) and execution risks. A 180-day lockup period will prevent early investors like OTPP from selling immediately post-IPO.
The irony has not been lost on observers. Ontario’s government previously canceled a Starlink rural internet contract amid political tensions involving Musk, yet the pension fund’s savvy investment, made when SpaceX was valued around $33-36 billion, and Starlink was nascent, delivers outsized gains independent of politics.
For OTPP, this windfall strengthens its already solid 111 percent funding ratio and underscores the value of patient, innovation-focused capital allocation.
For SpaceX, the IPO marks a new chapter: greater transparency, access to public markets for talent retention and growth capital, and heightened pressure to deliver on its multi-planetary vision.
All eyes are fixed on whether SpaceX can justify its lofty valuation through sustained execution. For Ontario teachers, the returns are already stellar, but SpaceX, like other Musk companies in the past, has plenty of things to prove. Perhaps the most ideal person for the job is at the helm, hoping to bring the company to a massive valuation.

SpaceX’s amended S-1 is sparking a major Tesla merger conversation
A single line in SpaceX’s amended S-1 just sent Tesla stock down 5% in one day.
A single line buried in SpaceX’s amended S-1 filing is doing more to move Tesla’s stock price than anything Tesla itself has announced in months. The clause, disclosed as SpaceX prepares for what could be the largest IPO in Wall Street history, states that the company “may issue a significant amount of equity in connection with future transactions.” While this may be seen as boilerplate language in S-1 filings, the historical ties between SpaceX and Tesla, and with Elon Musk reportedly discussing a possible merger with close colleagues, investors are interpreting it as something closer to a signal.
The concern among institutional investors like Gary Black, managing director of The Future Fund, pointed directly to the amended filing on X, saying it “strongly suggests more SPCX equity will be issued,” which could potentially be used to acquire Tesla. He estimated such a deal could be 28% dilutive to Tesla shareholders since SpaceX would likely command a significantly higher valuation multiple. Black added that institutional investors he knows hate the idea of a combination because they prefer pure plays over conglomerates, which he said “nearly always gravitate to the lowest common multiple.”
The Tesla and SpaceX merger everyone is talking about is quietly building
The bull case runs the math differently. Tesla influencer and retail shareholder advocate AleXandra Merz pushed back on what she called a widespread misunderstanding of how merger-of-equals deals actually work. Rather than simply splitting the difference between two market caps, a merger exchange ratio is negotiated based on relative fair market values, meaning the lower valued company typically sees its stock reprice upward toward the deal value.
Under her model, SpaceX enters at a $2.5 trillion valuation and Tesla at $1.6 trillion, producing a combined entity worth $4.1 trillion split evenly between both shareholder groups. That implies Tesla’s side of the deal would be valued at $2.05 trillion, a gain of roughly $450 billion from its current market cap. She cited Dow-DuPont and CBS-Viacom as historical examples of how markets reprice both companies toward the announced exchange ratio after a deal is unveiled.

The SpaceX S-1 amendments also revealed just how much financial infrastructure already binds the two companies together. As Teslarati has reported, SpaceX purchased $697 million in Tesla Megapacks, $131 million in Cybertrucks, and the two companies have shared supply chain resources, and semiconductor fabrication plans since well before any merger conversation became public. A retail poll by Tesla influencer Sawyer Merritt is finding that 36% of respondents do not plan to buy SpaceX shares at IPO and 15.3% saying their decision depends on the valuation.

Whether the merger happens or not, the amended filing is seemingly moving markets and sharpened a debate that is no longer theoretical. SpaceX is weeks away from trading publicly, and Tesla shareholders are now watching every word of every filing for clues about what Musk plans to do next.
