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.

SpaceXAI signs agreement with Anthropic for massive AI supercomputer access
SpaceXAI announced today that it had signed an agreement with Anthropic to give the company access to its Colossus 1 data center in Memphis, Tennessee.
It is a monumental deal as Anthropic will gain access to all of the compute at the plant, delivering more than 300 megawatts of power and over 220,000 NVIDIA GPUs within the month.
Anthropic’s Claude AI account on X announced the partnership:
“We’ve agreed to a partnership with SpaceX that will substantially increase our compute capacity. This, along with our other recent compute deals, means that we’ve been able to increase our usage limits for Claude Code and the Claude API.”
The company is also:
- Doubling Claude Code’s 5-hour rate limits for Pro, Max, and Team plans;
- Removing the peak hours limit reduction on Claude Code for Pro and Max plans; and
- Substantially raising its API rate limits for Opus models.
We’ve agreed to a partnership with @SpaceX that will substantially increase our compute capacity.
This, along with our other recent compute deals, means that we’ve been able to increase our usage limits for Claude Code and the Claude API.
— Claude (@claudeai) May 6, 2026
SpaceX also published its own release on the new agreement, noting that it is “the only organization with the launch cadence, mass-to-orbit economics, and constellation operations experience to make orbital compute a near-term engineering program rather than a research concept.”
CEO Elon Musk also commented on the partnership and shed light on intense meetings he had with senior members of Anthropic last week, stating, “nobody set on my evil detector.”
Same here.
By way of background for those who care, I spent a lot of time last week with senior members of the Anthropic team to understand what they do to ensure Claude is good for humanity and was impressed.
Everyone I met was highly competent and cared a great deal about…
— Elon Musk (@elonmusk) May 6, 2026
This has turned the argument that SpaceX is as much an AI company as a space exploration company into a very valid argument:
SpaceX is following in Tesla’s footsteps in a way nobody expected
Nevertheless, this is an incredibly valuable and important move in the grand scheme of things. AI scaling is fundamentally bottlenecked by compute, and demand for Claude has surged, bringing terrestrial power grids, land, and cooling operations hitting limits everywhere.
Anthropic has been aggressively signing multiple large-scale deals to be competitive in the space, including:
- Up to 5GW with Amazon
- 5GW with Google and Broadcom
- Strategic $30b Azure deal with Microsoft/NVIDIA
- $50b U.S. infrastructure investment with Fluidstack
Access to Colossus 1 gives Anthropic immediate relief on NVIDIA GPU capacity. For SpaceXAI, it turns its rapid buildout into revenue. It also showcases its ability to deliver at world-leading speed and scale.
Most importantly, it plants the seed that its much larger vision, orbital AI compute, is totally viable.
Starlink V3 satellites could enable SpaceX’s orbital computing plans: Musk
Within the month, Anthropic will begin using 100 percent of Colossus 1’s compute, directly expanding capacity for Claude Pro and Max subscribers and the API. This means fewer limits, faster responses, and support for heavier workloads.
In the long term, meaning 2026 and beyond, there will be a continued rollout of other multi-GW deals Anthropic has signed, and an early exploration of orbital compute with SpaceXAI.

SpaceX Board has set a Mars bonus for Elon Musk
SpaceX has given Elon Musk the goal to put one million people on Mars.
SpaceX’s board approved a compensation plan for Elon Musk that ties his pay directly to colonizing Mars and building data centers in outer space. The details surfaced this week after Reuters reviewed SpaceX’s confidential registration statement filed with the Securities and Exchange Commission, making it one of the first concrete looks inside the company’s financials ahead of a public offering.
The pay package will reportedly award Musk 200 million super-voting restricted shares if the company hits a market valuation milestone, with the most ambitious targets going further. To unlock the full award, SpaceX would need to reach a $7.5 trillion valuation and help establish a permanent human settlement on Mars with at least one million residents. Additional incentives are tied to developing space-based computing infrastructure capable of delivering at least 100 terawatts of processing power.
SpaceX wins its first MARS contract but it comes with a catch
Long before SpaceX filed anything with the SEC, Elon Musk had already spent years framing Mars colonization as an insurance policy against human extinction. The philosophy traces back to at least 2001, when Musk first began researching Mars missions independently, before SpaceX even existed. By 2002 he had founded the company with Mars as the stated long-term goal.
In a 2017 presentation at the International Astronautical Congress, Musk outlined the specific vision that still underpins SpaceX’s architecture today. He described a self-sustaining city on Mars requiring roughly one million people to become viable, the same number now written into his compensation package.
SpaceX’s Starship, still in active development, was designed from the ground up to support the eventual colonization of Mars. Musk has stated publicly that getting the cost per ton to Mars below $100,000 is necessary to make mass migration economically feasible. Everything from Starship’s payload capacity to its full reusability targets flows from that single constraint. One can say that Musk’s latest compensation package has put a formal valuation on Mars for the first time.
SpaceX is targeting an IPO around June 28, Musk’s birthday, at a valuation of approximately $1.75 trillion. Between the Mars rover contract, the Golden Dome software group, Space Force satellite launches, and now a pay structure built around interplanetary colonization, SpaceX has become the single most consequential contractor in American space and defense. The IPO will put a public price tag on all of it for the first time.

UPDATE: SpaceX’s Falcon Heavy that launched a Tesla into space is back on a mission
SpaceX Falcon Heavy returns after 18 months away to deliver a satellite that only it could carry.
UPDATE: 10:29 a.m. et: SpaceX is standing down from today’s Falcon Heavy launch of the ViaSat-3 F3 mission due to unfavorable weather. A new target date will be shared once confirmed.
After an 18-month absence, SpaceX’s Falcon Heavy is returning to mission on Monday morning when it’s scheduled to lift off from Launch Complex 39A at Kennedy Space Center at 10:21 a.m. EDT.
The mission is called ViaSat-3 F3, and the heavy satellite payload needs to reach geostationary orbit, sitting 22,236 miles above Earth where its speed matches the planet’s rotation. Getting a satellite that heavy to that altitude demands more thrust than a single-core Falcon 9 can deliver.
This marks the Falcon Heavy’s 12th flight overall since its debut in February 2018, and its first since NASA’s Europa Clipper mission in October 2024.
Arguably, the most exciting element for spectators will be watching the booster recoveries in action when the two side boosters, B1072 and B1075, will attempt simultaneous landings at Landing Zone 2 and the newer Landing Zone 40 at Cape Canaveral Space Force Station, while the center core will be expended over the ocean.
SpaceX wins its first MARS contract but it comes with a catch
Following satellite deployment, expected roughly five hours after launch, ViaSat-3 F3 will spend several months traveling to its final orbital slot before undergoing in-orbit testing, with service entry expected by late summer 2026
As Teslarati reported, NASA awarded SpaceX a $175.7 million contract on April 16, 2026, to launch the ESA Rosalind Franklin Mars rover aboard a Falcon Heavy no earlier than late 2028, which would mark the first time SpaceX has ever sent a payload to Mars. That contract came on top of an already deep pipeline that includes the Roman Space Telescope, the Dragonfly Saturn mission, and multiple national security payloads.
SpaceX executed 165 missions in 2025 and now accounts for approximately 85% of all global orbital launches. With Starlink surpassing 10 million subscribers and an IPO targeting a $1.75 trillion valuation still ahead, Monday’s launch is one more data point in a company that has quietly become the backbone of both commercial and government space access worldwide.
