SpaceX CEO Elon Musk arrives in Texas for milestone Starship engine test
On Saturday evening, SpaceX CEO Elon Musk landed in Waco, Texas – perhaps along with additional SpaceX propulsion engineers – for the critical static fire debut of the first “radically redesigned” Raptor engine, built to power BFR’s Starship upper stage and Super Heavy booster.
If the first operationalized Raptor’s static fire tests go well, there are several possible routes the test program could take, all of which will end up with this engine and several others being tested and ultimately installed on the Starship hopper (Starhopper) prototype under construction roughly 500 miles (800 km) south of SpaceX’s Raptor test cell.

Shortly after Musk revealed official photos of the first operationalized Raptor preparing for an inaugural static fire test at SpaceX’s McGregor, Texas facilities, the SpaceX and Tesla CEO’s private jet was seen landing at Waco, Texas around sunset. Although all SpaceX technical expertise needed for Raptor’s first ignition was probably already on site several days prior, Musk has been known to offer seats on his private planes to SpaceX and Tesla employees when a critical group is needed away from their normal base of operations. The best examples come from Tesla engineering expertise sometimes traveling between Fremont and Gigafactory 1 when needed, often to solve production holdups.
Regardless of whether he was traveling with members of the SpaceX propulsion team, Musk’s arrival at McGregor yesterday signified that Raptor Block 1’s first integrated hot-fire was imminent. Assuming no attempt was made on Saturday night or Sunday morning, SpaceX technicians and engineers are presumably still working on installing what is effectively a new rocket engine and ensuring that Raptor’s test cells – extensively overhauled and upgraded for the occasion – are working as intended. While the development Raptors SpaceX built hovered around 1000 kN (~100t) of thrust, also roughly the same as Merlin 1D, the Raptor now on stand in Texas is reportedly a 200 ton-class engine or more than double the thrust of any single engine SpaceX engineers and technicians have built or test-fired in 15 years of engine development.

A fork in the R&D road
Prior to completing Raptor Block 1 (unofficial designation), SpaceX cumulatively test-fired dev Raptors for far more than 1200 seconds over the course of more than 24 months. It’s unclear how extensively the company’s engineers will be able to test the pathfinder hardware built on the back of that extensive test program. Nominally, one would expect hundreds or thousands of seconds of additional testing to properly characterize the design and production of a brand-new, optimized engine like Raptor while primarily ensuring that it performs within engineering specifications.
Knowing CEO Elon Musk’s self-admitted tendency to push for impractical deadlines and schedules that often appeared rushed for the sake of rushing, it’s not impossible that the first Raptors could find themselves installed on the Boca Chica-based Starhopper test article after Merlin-esque acceptance testing and nothing more. For M1D and MVac, acceptance testing usually takes the shape of a full-duration burn with throttle and gimbal activity to closely simulate a true Falcon 9 or Heavy launch. For the 200-ton Raptor now in Texas, comparable acceptance testing could take a variety of forms, ranging from short Starhopper-relevant burns (10-60 seconds for small hops) to simulating conditions during a Super Heavy launch and landing or even a 6 or 7-minute orbital insertion burn indicative of the performance needed for Starship.

Depending on the interplay between the route SpaceX engineers would likely prefer and the Starhopper test schedule executives and managers might want, this first Raptor engine (and two more soon to follow) could be installed on Starhopper anywhere from a few weeks to several months from now. Elon Musk indicated in early January that he expected hop tests would occur 4-8 weeks later, shortly followed by unplanned damage to the craft’s nose cone that pushed the debut back “a few weeks”.
Aiming for 4 weeks, which probably means 8 weeks, due to unforeseen issues

I just heard. 50 mph winds broke the mooring blocks late last night & fairing was blown over. Will take a few weeks to repair.

Realistically, hop tests should thus be expected to begin no earlier than (NET) 8-12 weeks from the first week of January, translating to NET March or April. This would give SpaceX propulsion engineers a decent amount of time to gain at least a few hundred (or maybe 1000+) seconds of experience operating the newest and most advanced iteration of Raptor.

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.
Big news at the new Optimus 10m/y factory construction site today! The 1st steel structure has been erected & as expected the second phase of land reclamation is underway.
This will allow this new factory to grow to nearly the same length as the main Giga Texas factory,… pic.twitter.com/FidRLV6XpU

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
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.
