SpaceX Starship prototype ready for record-breaking tests

Published

on

Over the weekend, SpaceX has installed the last of its first orbital-class Starship’s six Raptor engines, setting the prototype up for one or several record-breaking tests later this week.

Tentatively scheduled as early as 10am to 6pm CDT on Monday Tuesday, November 1st 2nd, the next test up on Starship 20’s (S20) docket will likely be its third static fire in eleven days. Ship 20 completed its first Raptor-involved test – known as a preburner test – on October 19th, followed by two successful back-to-back static fires – one with one Raptor and one with two – on October 21st.

Less than 36 hours later, the Starship’s two missing Raptor Center (RC) engines (of a total of three) had been installed by Friday morning, October 22nd. For unknown reasons, no testing was completed the following week it and it took SpaceX another six and a half days to deliver the final two missing engines to the pad for installation on S20. Regardless, both missing Raptor Vacuum engines were installed by 2am CDT on Saturday, October 30th, marking the second time a Starship prototype has had all six Raptors installed.

While it might be the second time SpaceX has installed six Raptors on a Starship, it’s likely the first time six engines have been fully integrated with Ship 20’s propellant tanks, gas supplies, and avionics. How exactly SpaceX plans to proceed is unclear but odds are good that Starship S20’s next static fire test campaign will involve simultaneous igniting at least four of its six Raptor engines, setting a new record for the number of Raptors simultaneously ignited.

More likely than not, though, Ship 20’s next campaign will culminate in the simultaneous ignition of all six Raptors to (hopefully) complete the first true orbital-class Starship static fire. Like SpaceX has only just begun to do with Falcon boosters, flight-proven Starships might eventually be able to skip preflight static fire tests, but it’s virtually guaranteed that SpaceX will still proof test Starship and Super Heavy before flights until ships, boosters, and Raptors have stable designs with substantial flight experience. To ensure full-fidelity testing, those static fires will always have to qualify all installed engines. That includes Starship, which is designed to burn both its sea-level and vacuum-optimized Raptors from booster separation to orbit.

At full throttle, depending on the efficiency of its three RVacs at sea level, Starship S20’s six Raptor V1.0 engines could produce ~1100 tons (~2.4M lbf) of thrust. By comparison, SpaceX’s workhorse Falcon 9 rocket produces around 760 tons (~1.7M lbf) of thrust at liftoff, meaning that Starship will likely become the most powerful single-core rocket the company has ever tested even if it never throttles above ~70%.

There’s a good chance that SpaceX will start Ship 20’s next round of tests by separately firing both sets of three Raptor Center and Vacuum engines or with a mixed three or four-engine test to follow the latest two-engine test. SpaceX could also take the most iterative approach and test three, four, and five engines at a time before the final six-engine test. Regardless, virtually all possible static fire tests Ship 20 is now configured to perform will be program ‘firsts’ of some kind.

SpaceX to become America’s Military data backbone for missiles, drones, and warfighters

The Space Force just handed SpaceX $2.29 billion to build the military’s space internet backbone.

The U.S. Space Force awarded SpaceX a $2.29 billion contract on May 26, 2026 to build the backbone of its Space Data Network, a satellite-based communications system designed to keep American military forces connected anywhere on Earth in real time. The contract is firm-fixed-price and requires SpaceX to deliver a fully operational prototype by the end of 2027.

In plain terms, the SDN Backbone is the plumbing behind the military’s space-based internet. It functions as a low Earth orbit satellite constellation providing robust, high-capacity, and low-latency data transport for the Joint Force, connecting sensors and weapons systems continuously, globally, and securely. Think of it as a private, hardened version of Starlink built specifically for battlefield communications, one that soldiers, ships, and aircraft can rely on even in contested environments where ground-based networks have been disrupted.

SpaceX is quietly becoming the U.S. Military’s only reliable rocket

The Space Force was direct about why SpaceX was selected. “The SDN Backbone leverages the best of commercial innovation and delivers a strong foundation for the SDN mission set — a huge benefit and enabler for our warfighters,” said USSF Col. Ryan Frazier.

“We aren’t trading speed for scale; we are demanding both. By using rapid prototyping and Other Transaction Authorities, we are ensuring our advanced solutions are integrated and delivered to the warfighter as fast as possible,” added USSF Lt. Col. Fry, SDN Backbone system program manager.

The SDN Backbone will work alongside the Space Development Agency’s Transport Layer, with the two systems forming a unified open architecture to provide critical data transport for current and future Department of War missions.

As Teslarati has reported, this is not SpaceX’s first Space Force contract of 2026. In April, the Space Force awarded SpaceX $178.5 million to launch missile tracking satellites, and SpaceX is already embedded in the Golden Dome missile defense software group. The $2.29 billion SDN Backbone award puts SpaceX at the center of how the American military communicates in space, a position with direct implications for its reported $1.75 trillion IPO valuation as the company heads toward a public offering as early as June 2026.

Tesla’s dedicated factory for building up to ten million Optimus units is officially under construction at Gigafactory Texas.

Drone footage released on May 27 by Giga Texas observer Joe Tegtmeyer captures the significant milestone of the first steel structure officially standing at Tesla’s new Optimus factory on the North Campus of the facility.

Phase two of land reclamation is advancing steadily, and the progress will let the new building extend nearly the full length of the main Giga Texas factory, potentially exceeding 4,000 feet, while measuring somewhere between 50 and 70 meters narrower. Extensive foundation work is proceeding as well.

This facility forms a central element of Tesla’s broader North Campus expansion at Giga Texas. The project will add more than 5.2 million square feet of new industrial space. It sits alongside other advanced developments, including a Terafab for next-gen AI chips. The scale reflects Tesla’s commitment to transforming humanoid robotics into a core pillar of the company’s future.

Musk has said that Optimus will be the biggest product in the world on several occasions. He believes it will be Tesla’s biggest valuation contributor.

Tesla prepares to expand Giga Texas with new Optimus production plant

Tesla plans to build about 10 million robots at the site annually once it is completed, which would be about 27,000 units each day.

The Optimus plant at Giga Texas is part of Tesla’s phased strategy for Optimus manufacturing. In an effort to start production of the robot well before the Giga Texas plant is complete, Tesla ended production of the Model S and Model X vehicles, which were built in Fremont, California, to make way for initial Optimus manufacturing efforts.

Production there will start in either July or August of this year, and early units will support internal factory tasks while the team gathers real-world data to refine processes. The Gigafactory Texas facility will house a second-gen production line. It targets high-volume output starting in Summer 2027.

Musk has repeatedly described Optimus as potentially more valuable than Tesla’s entire vehicle business. Current versions are already completing minor tasks around various facilities, while Tesla continues to refine its abilities and add new features.

Tesla’s total investment could reach several billion dollars. Significant challenges lie ahead, including the creation of an entirely new manufacturing ecosystem, the refinement of AI systems for dependable autonomy, and the development of reliable supply chains for actuators, sensors, and other components.

Nevertheless, the visible progress at Giga Texas highlights Tesla’s capacity to translate ambitious concepts into physical reality.

Tesla’s Optimus factory stands as much more than a simple expansion project, as it is quite literally the second phase of what could potentially be the biggest product ever. With construction beginning, 2027 is poised to become a transformative year for Tesla, as it evolves even further from an electric vehicle leader into a pioneer of intelligent, general-purpose machines.

Tesla teases going Plaid Mode with the Model 3

Published

Tesla Vice President of Vehicle Engineering, Lars Moravy, recently revealed the company has thought about introducing a Plaid powertrain on the Model 3, but there could be some challenges involved.

On the Ride the Lightning podcast, Moravy revealed that he thinks about a Plaid Model 3 “all the time,” and it certainly has a place in Tesla’s potential lineup of future vehicles.

Now that the Plaid powertrain is technically defunct due to the newfound absence of the Model S and Model X, Tesla could find a way to reintroduce the lightning-quick trim level to its mass-market vehicles.

But there are going to be some challenges with it. Moravy said that the Model 3 Plaid would likely adopt the carbon-sleeved motors that the Model S Plaid had. However, packaging would be a major challenge, as Moravy said on the podcast, it would be a “tight engineering squeeze.”

It’s important to note that there are no active production plans for the Model 3 Plaid at this point, but it’s also worth noting that with the Model S and Model X Plaid no longer available, Tesla would likely be willing to introduce something that is even more white-knuckle than the Model 3 Performance, which already boasts a 2.9-second 0-60 MPH acceleration rate and a top speed of 163 MPH.

Of course, there is the Roadster, but we don’t know when that will exactly make it to market, and we know that, for sure, it will not be accessible to many.

Tesla unveils juicy new detail on the Roadster and hints at new unveil timeline

Tesla has prided itself in building some of the best cars out there, but they’re also interested in building cars that are simply fun to be in.

A Plaid Model 3 could truly push the limits and could end up being one of the best cars Tesla will ever build, especially if it can shave off at least half of a second from its 0-60 MPH time and increase its top speed slightly.

More than anything, the real changes will be in the ride and aerodynamics. Tesla improving things like the suspension, handling, and downforce will be the true trademarks of its Plaid powertrain; putting it in the Model 3 could be a great move for the company and for customers interested in high-end performance.
