Late at night on July 22nd, SpaceX’s South Texas team of technicians and engineers were busy testing a small but critical component of Starhopper, a testbed and low-fidelity Starship prototype meant to attempt its first untethered flight test as early as July 24th.

Monday evening’s testing centered around Starhopper’s cold gas nitrogen thrusters, multi-nozzle assemblies that appear to have quite literally been taken off of flight-proven Falcon 9 boosters. For Starhopper, they will act in a similar – albeit significantly reduced – fashion, serving to control the giant steel prototype’s attitude and augment its lone Raptor engine’s own thrust vectoring (i.e. steering) capability.

Although SpaceX has never released official numbers for the thrust of the cold gas thrusters used on Falcon 9 boosters and upper stages, it’s safe to say from their performance that the low-efficiency nitrogen thrusters produce roughly 5 kN (~1100 lbf) of thrust, perhaps up to 10+ kN. For an almost empty Falcon 9 booster, this translates to extremely rapid (sub-10s) flip maneuvers during return-to-launch-site (RTLS) landings.

At the same time, Falcon boosters have two sizes of cold-gas thrusters, with much larger high-performance (>10 kN) pods – located on the larger of the booster’s two raceways – focused on settling the rocket’s propellant after recovery-related coast periods. A duo of smaller 3-axis pods situated on the outside of the interstage serve as true attitude control system (ACS) thrusters, precisely pointing, flipping, and orienting boosters during vacuum operations and partially augmenting grid fin control authority during the late stages of landings. Despite their much smaller size, they still pack an impressive punch and are famous for almost saving tipping Falcon boosters during early (failed) landing attempts.

Starhopper, meanwhile, is dramatically larger than the Falcon 9 and Heavy boosters its tacked-on ACS thruster pods were designed for. It’s hard to know for sure but safe estimates peg the testbed’s dry mass somewhere around 50-75 metric tons (110,000-165,000 lb) thanks to the thick steel it was constructed out of. In other words, Starhopper likely weighs at least twice as much as an empty Falcon 9 booster (~25 metric tons).

To alleviate this mismatch, SpaceX arrived at a hilariously simple and cheap solution: install double the number of grave-robbed Falcon 9 thruster pods on Starhopper and voila! It was that duo of thruster pod pairs that were tested on July 22nd, visibly producing four distinct jets of pressurized nitrogen gas. Whenever Starhopper gets to hopping, those ACS thrusters should help the rocket precisely control its rotation, attitude, and – to a lesser extent – translation, hopefully helping to ensure a successful inaugural hover and divert test.

Scheduled to occur no earlier than Wednesday, July 24th, SpaceX plans to deconflict Cargo Dragon’s CRS-18 launch and Starhopper’s hover test, meaning that they will not happen simultaneously. In the ~70%-likely event that bad Florida weather delays CRS-18 to Thursday, July 25th, the road before Starhopper will be clear for an attempted hover on the 24th. Additionally, also reported first by NASASpaceflight.com, the test is expected to involve a divert, meaning that Starhopper will lift off, hover roughly 20m (65 ft) off the ground, and then carefully travel a few hundred feet East to a recently-constructed concrete pad for a soft landing.

This divert was tacitly confirmed by the arrival of a robotic transport mechanism, already used once before to move Starhopper from its build site to the launch pad. If the divert goes as planned, the transport equipment will be used to return Starhopper to its spartan launch mount and ground support equipment (GSE) umbilicals.

If Starhopper survives and Raptor SN06 performs nominally, it’s all but certain that the testbed rocket will be put through a series of increasingly ambitious test flights over the coming months – at least before SpaceX’s first higher-fidelity “Mk 1” Starship prototypes begin their own flight tests. According to CEO Elon Musk, those Starship test hops and flights could begin as few as 2-3 months from now – September or October 2019.

Elon Musk estimates Tesla Semi could reach Europe next year

“We’ve got the Tesla Semi coming out, the heavy truck, and that’ll be going to Europe hopefully next year,” Musk said.

Tesla is preparing to expand its all-electric Semi truck program to Europe, with CEO Elon Musk indicating that the Class 8 vehicle could arrive in the region 2027.

Musk shared his update during an interview about Giga Berlin with plant manager André Thierig, which was posted on X by the official Tesla Manufacturing account.

“We’ve got the Tesla Semi coming out, the heavy truck, and that’ll be going to Europe hopefully next year,” he said.

Tesla has already begun limited production and customer deployments of the Tesla Semi in the United States, with the company working to scale output through the Semi factory near Giga Nevada. Considering Musk’s comments, it appears that a European rollout would be the next phase of the vehicle’s expansion beyond North America.

Musk’s use of the word “hopefully” leaves room for flexibility, but the remark signals that Europe is next in Tesla’s commercial expansion plans.

Musk has consistently argued that electrification should extend beyond passenger vehicles. During the same interview, he reiterated his view that “all ground transport should be electric,” adding that ships, and eventually aircraft, would follow.

The Semi plays a central role in that strategy. Heavy-duty freight remains one of the most emissions-intensive segments of road transport, and European regulators have increasingly pushed for lower-emission commercial fleets. 

Tesla recently refreshed the Semi lineup on its official website, listing two variants: Standard and Long Range. The Standard trim offers up to 325 miles of range with an energy consumption rating of 1.7 kWh per mile, while the Long Range version provides up to 500 miles, which should be more than ample for European routes.

Tesla Cybercab coming next to Giga Berlin, Optimus possibly after

“From a next major product standpoint, I think most likely is the Tesla Cybercab,” Musk said.

Tesla could add the Cybercab and Optimus humanoid robot to the production lineup at Giga Berlin, as per recent comments from CEO Elon Musk. 

During a recent interview with Giga Berlin plant manager André Thierig, Musk identified the Cybercab as the most likely next major product for the German factory, with Optimus potentially following after.

“From a next major product standpoint, I think most likely is the Tesla Cybercab,” Musk said. He added that there are also “possibilities of Tesla Optimus” being produced in the facility.

Tesla has already begun production of the Cybercab in Giga Texas, with volume production expected to ramp this year. Based on Musk’s comments, it appears that if conditions align in Europe, Giga Berlin could eventually join that effort.

The CEO’s comments about Optimus coming to Gigafactory Berlin are quite unsurprising too considering that Musk has mentioned in the past that the humanoid robot will likely be Tesla’s highest volume product in the long run. 

Giga Berlin will likely be able to produce mass volumes of Optimus, as the Model S and Model X lines being converted to an Optimus line in the Fremont Factory are already expected to produce 1 million units of the humanoid robot annually. 

Apart from his comments about the Cybercab and Optimus, Elon Musk also confirmed that Giga Berlin has started ramping battery cell production and will continue expanding Model Y output, particularly as supervised Full Self-Driving (FSD) gains regulatory approvals in Europe.

Taken together, the remarks suggest Berlin’s role could evolve beyond vehicle assembly into a broader multi-product manufacturing hub, not just a regional Model Y plant.
