For the second time in two months, SpaceX technicians have begun to install a Raptor engine on Starhopper, a full-scale Starship testbed theoretically capable of low-velocity, moderate-altitude ‘hops’.

Back in late March, Raptor and Starhopper were joined for the first time, enabling a lengthy series of attempted tests that were followed by two engine ignitions and tethered hops before Raptor was removed for inspection. In the two months since that first round of integrated testing, SpaceX has significantly upgraded Starhopper and its spartan launch facilities, all focused on transforming the odd vehicle from a largely fixed test stand into a giant, mobile Grasshopper.

All the way back in 2012, SpaceX began testing Falcon 9 recovery and reusability concepts with a low-fidelity prototype known as Grasshopper – essentially a minimalist Falcon 9 first stage with ad hoc legs and a single Merlin engine. It supported a series of 8 major test flights – all successful and a source of valuable data – before the vehicle’s 2013 retirement. An upgraded Grasshopper – known instead as Falcon 9 Reusable Development Vehicle (F9R Dev1) – began testing around the same time and continued even higher altitude vertical takeoff/vertical landing (VTVL) tests until its untimely demise in August 2014.

Starhopper is quite similar, although it is also serving as a testbed for a far more varied range of technologies due to the fact that it has been developed before the inaugural launch of its namesake (Starship/Super Heavy). By the time SpaceX started Grasshopper/F9R tests, Falcon 9 had already completed several successful launches. With Starhopper, SpaceX is building and testing its first 9m-diameter ‘flight’ hardware, its first propellant tanks built out of steel, its first flight-capable rocket fueled by methane and oxygen, and its first mobile Raptor testbed, among numerous other things. The challenges are inherently much greater, but SpaceX has the luxury of taking the opposite approach it took towards Falcon 9 and building a launch vehicle entirely around its intended reusability, rather than trying to squeeze a method of reusability around an already-flying rocket.

Saurid Oddities

As noted by NASASpaceflight.com in a June 2nd article, SpaceX seems to be juggling its growing selection of newly-produced and tested Raptor engines in pursuit of Starhopper’s return to flight. According to the publication’s reliable sources,

“Up until recently, [SpaceX] was planning to utilize Raptor SN4 for [Starhopper’s first] untethered hops. However, the company has now decided to utilize this engine only for fit checks, and will instead perform the hops with SN5 – the latest Raptor to come out of SpaceX’s factory in Hawthorne, California.” – NASASpaceflight.com, June 2nd, 2019

This indicates that the Raptor engine delivered to Boca Chica on June 1st and currently in the process of being installed on Starhopper is actually more of a stand-in* for a future Raptor, SN05. The reasons behind this Raptor shuffle elude detection, but it’s possible that the simplest explanation – also posed by NASASpaceflight – is the correct one. By shipping a Raptor that may not be ready for flight tests, SpaceX could likely save anywhere from a few days up to a few weeks by doing everything short of lifting off under the powered of Raptor SN04.

*By all appearances, SN04 is a flight-grade Raptor that has completed assembly and likely been test-fired in McGregor, Texas. Why it may currently be resigned to a “stand-in” role is unknown.

Very curiously, upon Raptor SN04’s South Texas arrival, it appears that SpaceX technicians have indeed rapidly installed the engine on Starhopper, but in a position that is decidedly off-center. Pictured above, the photo could have simply caught the engine while technicians were moving it to its actual installation spot, but it could also indicate that SpaceX is speeding towards Starhopper’s first triple-Raptor test flights.

Starhopper delays?

In line with the last-second switch from Raptor SN04 to Raptor SN05 as the engine-to-be for untethered hops, SpaceX has pushed the start of that test series from approximately May 31st to June 11th. More likely than not, the ~11-day delay is meant to allow time for Raptor SN05’s McGregor, Texas acceptance testing, given that – per CEO Elon Musk – the engine wasn’t even finished as of May 22nd.

On the other hand, with Raptor SN05 now scheduled to support Starhopper hop tests as early as mid-June, it begs the question of whether SpaceX is instead working towards expedited triple-Raptor testing. For unknown reasons, neither Raptor SN03 or SN04 are apparently ready to support flight operations, although both have been thoroughly hot-fired in McGregor. Perhaps each engine is a distinct prototype with a different level of experimental readiness, or perhaps SpaceX is just testing certain engines (like SN03) more extensively than others (SN05).

Regardless, SpaceX now seems to have 3-4 intact, functional Raptor engines (excluding SN01; destroyed during stress testing), 2-3 of which are actively testing or being worked on a day’s drive north of Boca Chica. SN02 – having successfully supported a brief duo of ignition tests with Starhopper – could still be intact and test-ready. SN03 is an unknown quantity, but SN04 is clearly in excellent shape and is probably close to flight-readiness if it isn’t already. This is to say that SpaceX likely already has three Raptors on hand that are capable of supporting multi-engine Starhopper testing, whether or not such a test regime would actually be valuable.

Musk has noted that both orbit-capable Starship prototypes will be far closer to finished products and will thus fly with “at least 3 engines” (3 sea level engines, as it would turn out) or even “all 6” (3 sea level, 3 vacuum-optimized). In the meantime, Starhopper stands with an off-centered Raptor, awaiting the arrival of a different Raptor to kick off a second hop test program. If nothing else, SpaceX’s Starship/Super Heavy development program is operating in a spectacularly hardware-rich fashion, lending itself to the breakneck-pace of iteration and improvement SpaceX is famous for.

Tesla launches improved Model 3 in China with V2L, new interior option

Published

Credit: Tesla

Tesla has launched its newest iteration of the Model 3 in China with a slew of new features, including the highly requested V2L (vehicle-to-load) feature and a new interior option.

The Model 3 now has a 16″ front touchscreen with improved resolution, a black headliner, V2L capabilities, Zen Grey interior in the Premium and Performance trims, as the White option has officially been discontinued, and 19″ Dark Nova Wheels, which are standard on the Model 3 Premium only.

The touchscreen in the U.S. version of the Model 3 is just 15.4″, so the newly upgraded screen is .6″ larger. Additionally, the Black Headliner, now standard on Model Y vehicles in the U.S., is coming to China.

Additionally, Tesla’s decision to end the white interior option has also made its way to the Asian market, as Zen Grey is the lighter color consumers can now go with. It is slightly different from the previously offered White option:

These options are available in China, Australia, and New Zealand as well, as Giga Shanghai serves those markets, bringing its mass-market vehicles to those countries in the South Pacific.

The Model 3 trims are now priced at:

  • Rear-Wheel-Drive – 235,500 yuan (~$35,000)
  • Long Range Rear-Wheel-Drive – 259,500 yuan ($38,700)
  • Long Range All-Wheel-Drive – 285,500 yuan (~$42,600)
  • Performance – 339,500 yuan (~$50,600)

These features have yet to make their way to the U.S., which might upset some buyers, but it is probably a good sign that Tesla will bring these changes to U.S. trims sometime next year. Potentially, these could come even sooner, as they could be used to stimulate demand for the year-end sales push.

Nevertheless, when things start at Giga Shanghai, they usually end up in the U.S. market. Tesla has also already started to install things like the Black Headliner and larger touchscreen in certain U.S.-built vehicles, so these things will be easy to implement across other vehicles in the lineup.

The Pentagon taps Elon Musk to design the battlefield of the future

Hegseth named Elon Musk to help lead Project Meridian, a Pentagon study of future warfare.

Elon Musk has a new role in the Trump administration. Defense Secretary Pete Hegseth announced on war.gov Wednesday that Musk will help lead Project Meridian, a new Pentagon study meant to identify the weapons and technologies the U.S. military will need to fight wars decades from now.

Hegseth unveiled the project during his State of the Force address at Marine Corps Base Quantico in Virginia. Musk will direct the effort alongside Anduril founder Palmer Luckey and former House Speaker Newt Gingrich, working under Pentagon Chief Technology Officer Emil Michael. All three men were in attendance, and Hegseth said their first meeting would take place directly after the speech inside a secure compartmented facility, according to The Hill.

Hegseth said the group “will be focused on discovering, developing, and fielding the weapons and systems that our children and our grandchildren will need in their lifetimes, without any creative limitations or restrictions, on any future battlefield, from under the Earth to beyond the Moon.” He added that Meridian is not meant to produce new strategy or policy documents.

SpaceX to become America’s Military data backbone for missiles, drones, and warfighters

A memo released after the announcement gives Michael until January 28, 2027, to deliver findings, a window of 120 days. It names artificial intelligence, autonomy, directed energy, robotics and biotechnology as the fields expected to change how wars are fought. The results will come as a public report with a classified annex. The memo says the study will run through a partner organization it does not name, and it does not mention Musk directly. His role comes from Hegseth’s speech and a Pentagon press release.’

Musk had not commented publicly on the appointment as of Wednesday evening. This will be Musk’s first official advisory role in the administration since he left DOGE last year.

The mandate overlaps heavily with Musk’s companies. SpaceX is one of the Pentagon’s largest contractors, with 2026 defense awards topping $8 billion, much of it tied to launches and a suspected Starshield buildout out of Vandenberg. The Pentagon’s release says Meridian will examine domains “from subterranean depths to the cislunar frontier,” which maps onto The Boring Company’s tunneling and Starship’s lunar plans. Tesla’s work on autonomy and Optimus falls within the fields the memo lists.

Meridian was one of six initiatives Hegseth announced Wednesday. Another is a new Autonomous Warfare Command, which the department wants operating as a four-star combatant command by October 1, 2027.

The news lands a day before SpaceX is scheduled to fly a classified National Reconnaissance Office payload on Falcon Heavy, one of three launches the company has planned for Thursday.

SpaceX set to launch astronauts and a classified Falcon Heavy mission on the same day

SpaceX plans three launches Thursday, including Crew-13 astronauts and Falcon Heavy’s first classified NRO mission.

SpaceX is lining up one of the busiest single days in its history, and the company offered a preview on Wednesday morning with a simple post on X: “Sunrise at pad 40.” The video and photos show Falcon 9 standing at Space Launch Complex 40 at Cape Canaveral, roughly a day before it is scheduled to carry four astronauts to the International Space Station.

That launch is only the first of three SpaceX missions planned for Thursday, October 1, across both coasts.

Crew-13 is targeting liftoff at 11:10 a.m. ET, with a backup opportunity Friday at 10:47 a.m. ET. NASA astronaut Jessica Watkins will command the mission, with NASA’s Luke Delaney as pilot and Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov serving as mission specialists. According to NASA, Dragon is set to dock with the forward port of the station’s Harmony module around 8 p.m. ET, less than nine hours after launch. Watkins is the only member of the crew who has flown before, and Kutryk will become the first Canadian to reach orbit through NASA’s Commercial Crew Program.

The Falcon 9 booster is flying for the third time after supporting Crew-12 and a Starlink mission, and it will attempt a landing at Landing Zone 40 beside the pad. That site made its debut in February when the Crew-12 booster touched down there, as Teslarati reported at the time. Crew-13 will relieve the Crew-12 astronauts, who have been aboard the station since the middle of February.

On the West Coast, another Falcon 9 is scheduled to lift off from Vandenberg Space Force Base in a window running from 2:18 to 3:16 p.m. ET, a flight NASASpaceflight lists as a Transporter rideshare mission.

The day is set to close at 11:53 p.m. ET, when Falcon Heavy launches from Launch Complex 39A with NROL-97, the first National Reconnaissance Office payload ever to fly on the rocket. SpaceX rolled the vehicle out to the pad Tuesday night. Its two side boosters, which previously flew GOES-U, ViaSat-3 F3 and NASA’s Roman Space Telescope, will return to Landing Zones 1 and 2, while a new center core will be expended in the Atlantic. The Roman launch took place on August 30, so NROL-97 will come barely a month later as Falcon Heavy’s third flight of 2026 and 14th overall.

If all three Florida boosters land as planned, it would be the first time the Space Coast has seen landings at LZ-40, LZ-1 and LZ-2 on the same day, according to the Orlando Sentinel, which has warned residents in Brevard, Orange and Volusia counties that more than one sonic boom is possible.

The schedule arrives just three days after Starship reached orbit for the first time on Flight 14 from Starbase, Texas, deploying 26 Starlink V3 satellites. If Thursday’s missions stay on time, SpaceX will have flown Starship, Falcon 9 and Falcon Heavy from four different pads in about four days.

Crew-13 is also the start of a longer run for Dragon. NASA recently added Crew-15, Crew-16 and Crew-17 to SpaceX’s contract in a $946 million modification, keeping Dragon as the agency’s only operational ride to the station while Boeing’s Starliner remains grounded.
