Mysterious Air Force spaceplane returns to Earth more than two years after SpaceX launch
More than 25 months after it lifted off on a SpaceX Falcon 9 rocket, the US Air Force’s secretive X-37B spaceplane successfully returned to Earth on October 27th, breaking its own record for time spent in orbit.
As always, the specifics of what exactly the X-37B spaceplane does in orbit remain as obscure as ever.
SpaceX’s Falcon 9 rocket launched X-37B on its fifth mission – OTV-5 – on September 7th, 2017, just a handful of months after successfully launching a similarly secretive mission (NROL-76) for the National Reconnaissance Office (NRO) and a handful of months prior to the company’s even more mysterious ‘Zuma’ launch. SpaceX’s OTV-5 launch had to race against the clock to beat Hurricane Irma’s forecasted landfall and the company managed to launch just a few days prior, while the booster’s post-landing operations had to be similarly expedited.

Thankfully, all went as planned and SpaceX recovery technicians had Falcon 9 booster B1040 safely stored inside a nearby hangar before Hurricane Irma impacted the Florida coast. B1040 was reused for the second and final time during the June 2018 launch of the SES-12 communications satellite and marked the second to last launch of a pre-Block 5 variant of Falcon 9.
In the interim, the USAF X-37B was quietly stationed in low Earth orbit (LEO), performing any number of tasks. Over the course of the 779 days it spent in orbit, the spaceplane modified its orbit several times before finally reentering Earth’s atmosphere to land at Kennedy Space Center’s Shuttle Landing Facility (KSC SLF) runway.
During the OTV-4 mission that preceded OTV-5, the same X-37B spacecraft spent 717 days in orbit – just shy of two years. OTV-5 surpassed that endurance record on August 26th and remained in orbit for another two months, breaking its own record by a bit less than 10%. For the most part, the USAF’s most consistent cover story for the X-37B paints the spaceplane as a platform for testing reusable spacecraft hardware, but that explanation has never made a huge amount of sense alongside the fact that each mission has averaged more than 570 days in orbit.
“[The X-37B is the] Air Force’s premier reusable and unmanned spacecraft providing the performance and flexibility to improve technologies in a way that allows scientists and engineers to recover experiments tested in a long-duration space environment.”
USAF, October 27th, 2019
In reality, it’s largely assumed that X-37B serves as a kind of flexible, on-call spy satellite, featuring a payload bay with plenty of room for signals intelligence or imaging hardware and a level of orbital endurance that makes it comparable to satellites. For example, OTV-5’s orbital parameters meant that the spacecraft routinely overflew Russia for much of the 25 months it spent in space.

Aside from the “experiments” and likely espionage-related payloads X-37B can stow inside its payload bay, the spacecraft also brings along a small solar array and radiator and features a hydrazine maneuvering system with substantial delta-V reserves, allowing it to significantly change its orbit.
In an unexpected twist, the USAF press release suggested that X-37B also provided “a ride for small satellites”, unusual because the US never registered those satellites with the UN if they were actually deployed from the spacecraft – a potential violation of international spaceflight treaties.
Following its successful October 27th recovery, Boeing and USAF teams will begin the process of refurbishing X-37B and preparing it for its sixth orbital mission as soon as possible. Known as OTV-6, the spacecraft is scheduled to head to orbit once more on a ULA Atlas V rocket that is scheduled to launch no earlier than Q2 2020.

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.
