According to SpaceX CEO Elon Musk, the next round of Starhopper activity will focus on removing the spacecraft prototype’s tethers and performing far more substantial hop tests.

Longer tests demand that SpaceX begins expanding the known performance envelope of its full-scale Raptor engine. Towards that end, longer-duration tests would need to be done at the company’s McGregor, TX development facilities to reduce risk, tests that Musk confirmed are already well underway. A recent Raptor static fire reportedly lasted no less than 40 seconds, more than enough time for a single-engine Starhopper to significantly expand both the maximum altitude and velocity of future hop tests. In support of the upcoming Starhopper test campaign, significant construction work is also ongoing at SpaceX’s Boca Chica test and development facilities.

Unleashing the Hopper

During the months of March and April, SpaceX’s South Texas team effectively completed Starhopper and put the prototype through its first real tests. The process began with tank proof tests in which Starhopper’s tanks were filled with liquid nitrogen – relatively neutral and unreactive – to safely identify and repair any leaks, while also subjecting the vehicle to cryogenic temperatures. The proof testing also put the newly installed ground systems (GSE) and vehicle-pad connection hardware through their paces before moving to Starhopper’s nominal liquid oxygen and liquid methane propellant.

Following at least half a dozen or so wet dress rehearsals (WDRs) that saw Starhopper loaded with LOx and methane, SpaceX technicians analyzed the health of the prototype and soon began live tests with a Raptor engine installed. Designed to produce no less than 2000 kN (450,000 lbf, 205 mT) of thrust at full throttle, Raptor offers more than twice the max thrust of the latest variant of the Merlin 1D engine that powers Falcon 9 and Heavy (941 kN or 212,000 lbf). In other words, a single Raptor should be more than enough to lift Starhopper off the ground 150+ tons of propellant aboard.

In the above tweets, Musk indicates that Starhopper’s next step will be untethered hop tests powered by one Raptor engine. This is further supported by confirmation that Raptor completed its longest static fire test yet on April 27th.

After several unsuccessful test attempts, Starhopper completed two static fires (<10s combined) and hopped – tethered – a handful of feet off the ground on April 3rd and 5th, three weeks after Raptor was first installed. Days later, the lone Raptor engine was removed from Starhopper and shipped back to SpaceX’s Hawthorne, CA factory or McGregor, TX testing facilities for post-test analysis and inspection. In short, SpaceX used Starhopper as a sort of ad hoc test stand for the second serial Raptor (SN02) produced, completing two major acceptance tests simultaneously.

A handful of concise tweets published by Musk in the last few days of April implicitly confirmed that the next steps for Starhopper involved untethered flights off its South Texas pad, once again powered by a single Raptor engine. As both the prospective altitudes and flight times rise for future Starhopper tests, so do the risks posed to SpaceX’s adjacent facilities and the prototype itself. To minimize those risks and progress the Raptor program as a whole, SpaceX has been extensively testing the third serial Raptor (SN03) at its McGregor facilities. Instead of a rushed test regime similar to the one that almost completely destroyed Raptor SN01 less than two weeks after testing began, SN03 is participating in a more cautious and systematic series of tests.

Confirmed by Elon Musk, this included significantly increasing the length of Raptor SN03’s latest static fires, culminating in an April 27th test that lasted ~40 seconds. Above all else, long test fires are necessary to demonstrate that Raptor can reliably operate for dozens of seconds at a time, given that any failure leading to a loss of thrust could cause Starhopper – basically a controlled explosive device – to fall out of the sky. The famous Musk/SpaceX ethos of moving fast and breaking things does not preclude a pragmatic attitude towards the destruction of facilities and prototypes that could take months and millions of dollars to rebuild.

The ETA of future hop tests is unclear. For the time being, it appears that SpaceX’s South Texas facilities will be caught up in construction work for at least another week. Whether or not Raptor SN03 is next in line for installation on Starhopper, SpaceX will likely put it through several more long-duration static fires before moving ahead with untethered hop tests. All things considered, the rough Starship prototype is unlikely to restart powered testing for another two or so weeks. Stay tuned!

Ford is charging for a basic EV feature on the Mustang Mach-E

When ordering a new Ford Mustang Mach-E, you’ll now be hit with an additional fee for one basic EV feature: the frunk.

Ford is charging an additional fee for a basic EV feature on its Mustang Mach-E, its most popular electric vehicle offering.

Ford has shuttered its initial Model e program, but is venturing into a more controlled and refined effort, and it is abandoning the F-150 Lightning in favor of a new pickup that is currently under design, but appears to have some favorable features.

However, ordering a new Mustang Mach-E now comes with an additional fee for one basic EV feature: the frunk.

The frunk is the front trunk, and due to the lack of a large engine in the front of an electric vehicle, OEMs are able to offer additional storage space under the hood. There’s one problem, though, and that is that companies appear to be recognizing that they can remove it for free while offering the function for a fee.

Ford is charging $495 for the frunk.

Interestingly, the frunk size varies by vehicle, but the Mustang Mach-E features a 4.7 to 4.8 cubic-foot-sized frunk, which measures approximately 9 inches deep, 26 inches wide, and 14 inches high.

When the vehicle was first released, Ford marketed the frunk as the ultimate tailgating feature, showing it off as a perfect place to store and serve cold shrimp cocktail.

Ford Mach-E frunk is perfect for chowders and chicken wings, and we’re not even joking

It appears the decision to charge for what is a simple advantage of an EV is not going over well, as even Ford loyal customers say the frunk is a “basic expectation” of an EV. Without it, it seems as if fans feel the company is nickel-and-diming its customers.

It will be pretty interesting to see the Mach-E without a frunk, and while it should not be enough to turn people away from potentially buying the vehicle, it seems the decision to add an additional charge to include one will definitely annoy some customers.

Tesla to improve one of its best features, coding shows

According to the update, Tesla will work on improving the headlights when coming into contact with highly reflective objects, including road signs, traffic signs, and street lights. Additionally, pixel-level dimming will happen in two stages, whereas it currently performs with just one, meaning on or off.

Tesla is looking to upgrade its Matrix Headlights, a unique and high-tech feature that is available on several of its vehicles. The headlights aim to maximize visibility for Tesla drivers while being considerate of oncoming traffic.

The Matrix Headlights Tesla offers utilize dimming of individual light pixels to ensure that visibility stays high for those behind the wheel, while also being considerate of other cars by decreasing the brightness in areas where other cars are traveling.

Here’s what they look like in action:

As you can see, the Matrix headlight system intentionally dims the area where oncoming cars would be impacted by high beams. This keeps visibility at a maximum for everyone on the road, including those who could be hit with bright lights in their eyes.

There are still a handful of complaints from owners, however, but Tesla appears to be looking to resolve these with the coming updates in a Software Version that is currently labeled 2026.2.xxx. The coding was spotted by X user BERKANT:

According to the update, Tesla will work on improving the headlights when coming into contact with highly reflective objects, including road signs, traffic signs, and street lights. Additionally, pixel-level dimming will happen in two stages, whereas it currently performs with just one, meaning on or off.

Finally, the new system will prevent the high beams from glaring back at the driver. The system is made to dim when it recognizes oncoming cars, but not necessarily objects that could produce glaring issues back at the driver.

Tesla’s revolutionary Matrix headlights are coming to the U.S.

This upgrade is software-focused, so there will not need to be any physical changes or upgrades made to Tesla vehicles that utilize the Matrix headlights currently.

Elon Musk’s xAI has signed an agreement with the United States Department of Defense (DoD) to allow Grok to be used in classified military systems.

Previously, Anthropic’s Claude had been the only AI system approved for the most sensitive military work, but a dispute over usage safeguards has reportedly prompted the Pentagon to broaden its options, as noted in a report from Axios.

Under the agreement, Grok can be deployed in systems handling classified intelligence analysis, weapons development, and battlefield operations. 

The publication reported that xAI agreed to the Pentagon’s requirement that its technology be usable for “all lawful purposes,” a standard Anthropic has reportedly resisted due to alleged ethical restrictions tied to mass surveillance and autonomous weapons use.

Defense Secretary Pete Hegseth is scheduled to meet with Anthropic CEO Dario Amodei in what sources expect to be a tense meeting, with the publication hinting that the Pentagon could designate Anthropic a “supply chain risk” if the company does not lift its safeguards. 

Axios stated that replacing Claude fully might be technically challenging even if xAI or other alternative AI systems take its place. That being said, other AI systems are already in use by the DoD. 

Grok already operates in the Pentagon’s unclassified systems alongside Google’s Gemini and OpenAI’s ChatGPT. Google is reportedly close to an agreement that will result in Gemini being used for classified use, while OpenAI’s progress toward classified deployment is described as slower but still feasible. 

The publication noted that the Pentagon continues talks with several AI companies as it prepares for potential changes in classified AI sourcing.
