SpaceX has scrubbed its latest Starship static fire test for the third time since Friday but if another attempt succeeds within the next few days, a full-scale Starship prototype could lift off for the first time later this week.

SpaceX has attempted to perform a Starship static fire every day for the last three days without any luck, foiled by what must be mild technical issues and some extreme South Texas weather. That static fire – set to be Starship serial number 4’s (SN4) third – is required because SpaceX chose to replace the rocket’s installed Raptor engine (SN18) around 10 days ago after completing two successful tests on May 4th and 5th. Installed a few days after SN18 was removed, Starship and Raptor SN20 must now perform their own integrated static fire to ensure the complex systems are working properly.

Since SN4’s last test, SpaceX teams have been swarming the Starship prototype day and night, installing new COPVs (composite overwrapped pressure vessels; used to store high-pressure gas), new plumbing, and more. The specific purposes of all those in-situ changes can only be speculated at but what is clear is that SpaceX is preparing Starship SN4 for the first attempted flight test of a full-scale prototype, following in the footsteps of Starhopper’s bizarre but successful July and August 2019 hops. As SN4’s third Raptor static fire has slipped, though, so has that flight test. While the FAA has yet to officially publish a license for the 150m (~500 ft) Starship hop, NOTAMs (Notices to Airmen) filed recently suggest that that license and hop could come any day now.

Most recently, a NOTAM was filed on May 18th for what is likely Starship’s 150m hop test on Thursday, May 21st. Filed before SN4’s May 18th static fire test was aborted twice, that proposed May 21st hop test will almost certainly be delayed at least as long as the static fire that needs to precede it and is also dependent upon the FAA officially licensing the flight. The fact that NOTAMs are being filed for that flight strongly suggests that SpaceX and the FAA or in the late stages of hammering out a license, a process that can often involve a great deal of back-and-forth and compromise for experimental rocket launches.

Regardless, if or when Starship SN4 finally manages to fire up its new Raptor engine, it could be just a matter of days after that SpaceX attempts the first true Starship flight test. If everything goes according to plan, the ~30m (~100 ft) tall stainless steel rocket will lift off under the power of a single asymmetrically installed Raptor engine, capable of producing up to 200 metric tons (~450,000 lbf) of thrust with cryogenic liquid methane and oxygen propellant.

After lifting off from its ad-hoc South Texas launch mount, Starship SN4 will attempt to reach a peak altitude of 150m (~500 ft) and descend back down for a soft landing on an adjacent concrete pad, just like Starhopper did around nine months ago. A lot could go wrong: aside from using steel more than three times thinner than Starhopper’s, Starship SN4 will also be debuting an entirely new kind of landing leg, will be flying with asymmetric thrust, and will likely be using autogenous pressurization — all new challenges for SpaceX.

Nevertheless, there are also reasons for confidence. SpaceX has already successfully pressurized Starship SN4 all the way to 7.5 bar (~110 psi, sufficient for uncrewed orbital flight), performed multiple wet dress rehearsals and two Raptor static fire tests, and even tested what appears to be a new kind of cold gas thruster needed for roll control. Most importantly, even if Starship SN4 is destroyed during its next static fire or inaugural flight attempt, Starship SN5 is nearly at the same stage of completion and should be ready to take the reins almost immediately after the potential demise of its predecessor. With Crew Dragon’s inaugural NASA astronaut launch scheduled on May 27th, the rest of the month is set to be quite the event.

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 Optimus factory construction officially underway at Giga Texas

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.
