SpaceX test-fires Falcon 9 Block 5 booster for upgraded rocket’s fifth launch

Published

After a couple of weeks of mysterious delays, SpaceX is once again back in the saddle for its next orbital mission and has successfully completed Falcon 9’s routine prelaunch wet dress rehearsal and static fire. This rocket will launch Telstar 19V’s (launched in July) sister communications satellite Telstar 18V to a high-energy transfer orbit at 11:28 PM EDT, September 8 (03:28 UTC, September 9).

SpaceX’s static fire testing – conducted once in Texas with just the first stage and once at the launch site with the upper stage attached – is very nearly identical to a real launch, save for the fact that the rocket is not allowed to actually lift off from the pad, and only ignites its main engines for a handful of seconds.

Almost entirely unique to SpaceX in the launch industry, Falcon 9 and Falcon Heavy are perhaps the only operational (orbital-class) rockets in the world to still conduct routine test fires of integrated segments, including both boosters, upper stages, and even Dragon spacecraft thrusters (both Crew and Cargo variants). Other launch providers like ULA, Arianespace, and Roscosmos will typically test engines individually, but that testing is often not even routine – spot checks more than anything systematic.

In fact, SpaceX’s system of hardware testing as extraordinarily extensive. Aside from test firing integrated boosters and upper stages, SpaceX doubles down on that testing both at the launch site and in Texas. Prior to integrated testing, essentially all rocket engines (sea-level Merlin 1Ds, vacuum Merlin 1Ds, SuperDraco thrusters, Draco thrusters, and Falcon’s cold gas maneuvering thrusters) are hot-fire (or cold-fire, in the case of the cold gas thrusters) tested in Texas after completing assembly in Hawthorne.

 

After that, the individual rocket engines and thrusters are shipped back to Hawthorne, integrated into their Dragon, Falcon upper stage, or Falcon booster parent rocket, and then shipped back to Texas once more for integrated test-fires, shipped to their launch site, and test-fired yet again (in the case of Falcon 9 and Heavy, not Dragon). This extraordinarily systematic testing apparatus is without a doubt unique to SpaceX, with the only closest comparison being found in small launch startup Rocket Lab, which is also extensively vertically integrated, including in-house tests of all engines prior to shipment.

Much like modern aircraft (particularly airliners) routinely test all critical systems prior to takeoff, particularly a full-thrust engine check with brakes applied, SpaceX and Rocket Lab are explicitly attempting to replicate in spaceflight the sort of practices that have helped to make air travel perhaps the safest and most reliable method of transportation ever created by humans.

SpaceXAI signs agreement with Anthropic for massive AI supercomputer access

Published

on

Credit: SpaceX

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.

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.”

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.

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.

Rendering of a colonized Mars by way of SpaceX

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.
