According to NASASpaceflight.com, SpaceX is just ~48 hours away from Falcon Heavy Flight 3’s critical static fire test, in which all 27 of the rocket’s Merlin 1D engines will be briefly ignited.

If the routine test goes as planned, SpaceX’s third completed Falcon Heavy will be ready to lift off as early as 11:30 pm ET (03:30 UTC), June 24th. Atop the massive rocket will be the US Air Force’s Space Test Program-2 (STP-2) mission, a collection of 24 small satellites from a variety of US government agencies and academic institutions. Practically speaking, STP is often more of an engineered excuse to launch, involving satellites and customers that are willing to accept higher risk than more valuable payloads, making it far easier for the US military to certify new technologies and new commercial launch vehicles.

As previously discussed on Teslarati, STP-2 is an extremely ambitious mission that aims to simultaneously certify or pave the way towards certification of critical capabilities. First and foremost, it will (barring serious anomalies) give the US military the data it needs to certify SpaceX’s Falcon Heavy rocket for all national defense launches, giving ULA’s Delta IV Heavy its first real competition in a decade and a half.

Each of those three rocket nozzles is roughly 2.5m (8 feet) across, plenty of room for all but the tallest humans to stand up in.

Included under the umbrella of that catch-all certification is a sort of torture-test validation of the long-coast capabilities of SpaceX’s Falcon upper stage. To successfully complete STP-2, the upper stage will be subjected to “four separate upper-stage engine burns, three separate deployment orbits, a final propulsive passivation maneuver, and a total mission duration of over six hours.” It will likely be SpaceX’s most technically-challenging launch ever.

To complete STP-2, Falcon Heavy’s upper stage – essentially the same thing that flies on Falcon 9 – will be subjected to its most challenging mission profile yet. (SpaceX)

Finally, the US Air Force has decided that STP-2 presents an excellent opportunity to begin the process of certifying flight-proven SpaceX rockets for military launches. The STP-2-related work is more of a preliminary effort for the USAF to actually figure out how to certify flight-proven commercial rockets, but it will still be the first time the a dedicated US military mission has flown on a flight-proven launch vehicle. Down the road, the processes set in place thanks – in part – to STP-2 and Falcon Heavy may also apply to aspirational rockets like Blue Origin’s New Glenn and ULA’s “SMART” concept for Vulcan reuse.

Still, New Glenn is unlikely to be ready for flight-proven military launches until the mid-2020s, while ULA has no plans to even attempt to implement Vulcan’s “SMART” reuse until ~2026, meaning that military certification probably wont come until 2028-2030 at the earliest. SpaceX has thus earned roughly half a decade where it will be the only viable US launch provider that can offer certified flight-proven hardware with an established record of reliability. Although the Air Force Research Laboratory (AFRL) had a lone smallsat aboard SpaceX’s February 2019 launch of PSN-6 and Spaceflight’s GTO-1 mission, STP-2 will be the first time a dedicated Department of Defense mission has flown on flight-proven launch vehicle hardware since 1992 (STS-53).

Aside from flight-proven Falcon Heavy side boosters B1052 and B1053, STP-2 is expected to use a new center core, B1057. SpaceX is in the late stages of vehicle integration and should be nearly complete by Monday, June 17th in order to support a June 18th static fire. The specific static fire window is not yet public but Falcon Heavy will likely roll out to Pad 39A no less than 12 hours before.

Tesla Model X shocks everyone by crushing every other used car in America

The Model X is one of Tesla’s flagship models, the other being the Model S. Earlier this year, Tesla confirmed it would discontinue production of both the Model S and Model X to make way for Optimus robot production at the Fremont Factory in Northern California.

The Tesla Model X was the fastest-selling used vehicle in the United States in the first quarter of the year, crushing every other used car in America.

iSeeCars data for the first quarter shows that the Model X was the fastest-selling used car, lasting just 25.6 days on the market on average, two days better than that of the second-place Lexus RX 350h. The Cybertruck, Model Y, and Model S, in seventh, ninth, and thirteenth place, respectively, also made the list.

The Model X is one of Tesla’s flagship models, the other being the Model S. Earlier this year, Tesla confirmed it would discontinue production of both the Model S and Model X to make way for Optimus robot production at the Fremont Factory in Northern California.

Tesla brings closure to flagship ‘sentimental’ models, Musk confirms

Bringing closure to these two vehicles signaled the end of the road for the cars that have effectively built Tesla’s reputation for luxury and high-end passenger vehicles.

Relying on the sales of its mass market Model Y and Model 3, as well as leaning on the success of future products like the Cybercab, is the angle Tesla has chosen to take.

Teslas are also performing extremely well as a whole on the resale market. iSeeCars data shows that, “while the average price of a 1- to 5-year-old non-Tesla EV fell 10.3% in Q1 2026 year-over-year, the average price of a used Tesla was essentially flat at 0.1% lower across the same period. Traditional gas car prices dropped 2.8% during this same period.”

Additionally, market share for gas cars has dropped nearly 3 percent since the same quarter last year. Tesla has remained level, while the non-Tesla EV market share has increased 30 percent, mostly due to more models available.

Nevertheless, those non-Tesla EVs have seen their value drop by over 10 percent, while Tesla’s values have remained level.

Executive Analyst Karl Brauer said:

“Used electric vehicles without a Tesla badge have lost more than 10% of their value in the past year. This compares to stable values for Teslas and hybrids, and a modest 2.8% drop for traditional gasoline vehicles.”

Teslas, as well as non-luxury hybrids, are displaying the strongest resistance in the face of faltering demand, the publication says. But the more impressive performance is that of the Model X alone.

Tesla’s decision to stop production of the Model X may have played some part in the vehicle’s pristine performance in Q1. With the car already placed at a premium price point, used models are already more appealing to consumers. Perhaps second-hand versions were more than enough for those who wanted a Model X, and only a Model X.

Tesla Cybertruck’s head-scratching trim sold terribly, recall documents reveal

The head-scratching offering was only available for a few months, and evidently, it did not sell very well, which we all suspected. New recall documents on the vehicle from the National Highway Traffic Safety Administration (NHTSA) now reveal just how poorly it sold.

After Tesla decided to build a Rear-Wheel-Drive Cybertruck trim back in 2025, which was void of many features and only featured a small discount.

The head-scratching offering was only available for a few months, and evidently, it did not sell very well, which we all suspected. New recall documents on the vehicle from the National Highway Traffic Safety Administration (NHTSA) now reveal just how poorly it sold.

The recall deals with a potentially separating wheel stud and potentially impacts 173 Cybertruck units with the 18-inch steel wheels. The Cybertruck RWD was the only trim level to feature these, and the 173 potentially impacted units represent a portion of the population of pickups. Therefore, it’s not the entire number of RWD Cybertruck sold, but it could show how little interest it gathered.

The NHTSA document states:

“On affected vehicles, higher severity road perturbations and cornering may strain the stud hole in the wheel rotor, causing cracks to form. If cracking propagates with continued use and strain, the wheel stud could eventually separate from the wheel hub.”

Only 5 percent are expected to be impacted, meaning less than 10 units will have the issue if the NHTSA and Tesla estimates are correct. Nevertheless, the true story here is how terribly the RWD Cybertruck sold.

Tesla ended production and stopped offering the RWD Cybertruck to customers last September. For just $10,000 less than the All-Wheel-Drive trim, Tesla offered the RWD Cybertruck with just one motor, textile seats instead of leather, only 7 speakers instead of 15, no Rear Touchscreen, no Powered Tonneau Cover for the truck bed, and no 120v/240v outlets.

Tesla brings closure to head-scratching Cybertruck trim

For just $10,000 more, at $79,990, owners could have received all of those premium features, as well as a more capable All-Wheel-Drive powertrain that featured Adaptive Air Suspension. The discount simply was not worth the sacrifices.

Orders were few and far between, and sources told us that when it was offered, sales were extremely tempered because customers could not see the value in this trim level.

Even Tesla’s most loyal supporters thought the offering was kind of a joke, and the $10,000 extra was simply worth it.

Tesla Semi sends clear message to Diesel rivals with latest move

Tesla has officially launched Semi production at what will be a mind-boggling rate of approximately 50,000 units per year.

The truck is being built at a dedicated facility in Sparks, Nevada, just next to its Gigafactory Nevada facility.

The company finally announced on April 29 that the first Tesla Semi truck has rolled off its new high-volume production line at the factory. This marks the transition from limited pilot builds to scaled manufacturing for the Class 8 all-electric heavy-duty truck, nearly nine years after its dramatic 2017 unveiling.

Tesla initially promised high-volume deliveries by 2019–2020, but battery supply constraints and prioritization for passenger vehicles delayed progress. The new 1.7-million-square-foot factory, purpose-built next to Gigafactory Nevada’s 4680 cell production lines, resolves those bottlenecks through deep vertical integration.

The Semi uses Tesla’s structural battery packs with cylindrical 4680 cells manufactured on-site. This integration enables efficient supply, reduced logistics costs, and the potential for high output. The factory is designed for an eventual annual capacity of approximately 50,000 trucks, positioning Tesla to address growing demand in long-haul freight electrification.

Tesla is using a redesigned Cybertruck battery cell to mitigate Semi challenges

Operating economics favor the Semi through dramatically lower fuel and maintenance costs compared to traditional diesel rigs, and companies involved in a pilot program for the Semi with Tesla have shown that.

Electricity is far cheaper than diesel on a per-mile basis, while the electric powertrain features fewer moving parts, reducing service intervals and lifetime expenses. Early deployments with customers like PepsiCo and others have validated these advantages in real-world service.

The Nevada factory’s ramp-up is targeted for full volume output before the end of June 2026, aligning with broader Tesla production goals for 2026. This includes parallel efforts on other new vehicles while expanding the Megacharger infrastructure to support widespread adoption.

By localizing battery and truck production, Tesla gains advantages in cost, quality control, and scalability that many competitors sourcing cells externally lack. The start of high-volume Semi production represents a pivotal step in Tesla’s strategy to electrify heavy transportation, potentially accelerating the shift toward zero-emission freight across North America and beyond.

As output increases, the Semi could reshape long-haul logistics with its combination of performance, efficiency, and sustainability.
