SpaceX's "Christmas tree" is a Raptor engine for the holidays
SpaceX CEO Elon Musk showed off a holiday-themed Raptor engine “Christmas tree” with its very own star on top. Musk noted via a tweet that the company’s Starship propulsion team is “making great progress” building, testing, and refining the Raptor engines that will one day propel the next-generation rocket to Earth orbit and beyond.
On December 13th, Musk revealed that SpaceX is preparing to ship the 17th completed Raptor engine to the company’s McGregor, Texas rocket test and development facilities, the site of several dedicated test stands for the Starship engine. Likely one of the most complex rocket engines ever designed, built, or tested, Raptor relies on an exotic combustion cycle, referring to the specifics of how engines turn their propellant into meaningful thrust.
Raptor uses what is known as full-flow staged combustion (FFSC) and is the first FFSC engine to graduate beyond ground testing and actually fly, thus far having completed two flight tests in July and August 2019 as part of SpaceX’s Starhopper test campaign. In simple terms, the FFSC cycle aims to extract as much energy from a rocket’s propellant as efficiently as possible, resulting in what is theoretically the most efficient possible chemical propulsion from a given fuel and oxidizer combination.
Due to the sheer complexity required to achieve full-flow staged combustion, the engine type is incredibly rare and only two other (once) functional examples exist – one developed by Soviet engineers in the 20th century and the other built, tested, and inexplicably scrapped by NASA in the 2000s. In fact, the Soviet RD-270 engine’s thrust-to-weight ratio is likely second only to SpaceX’s own Merlin 1D engine, an absolutely spectacular achievement for a propulsion bureau operating in the late 1960s.
RD-270 had major development challenges and would likely have taken years of additional hardware-rich (i.e. destructive trial and error) testing to produce an engine actually capable of reliable flight. Before the program was cancelled in 1970, 22 engines were tested and no single RD-270 survived to perform a fourth static fire, a testament to the immense challenge of FFSC engines.
SpaceX appears to have had a much better go of it with Raptor, although many, many engines have definitely been destroyed or irreparably damaged since the full-scale engine’s February 2019 static fire debut. SpaceX CEO Elon Musk says that the 17th completed Raptor engine is almost ready to head to McGregor, Texas to kick off development and acceptance testing.
It remains to be seen when exactly Raptor engines will be mature and reliable enough to perform the 3-10 minute burns needed to send a Starship to orbit, let alone the Moon or Mars, but Musk appears confident that SpaceX is making great progress along those lines.
Per photos and info posted by NASASpaceflight.com earlier today, Raptor engine SN15 is already installed on a recently-reactivated McGregor test stand ahead of its first rocket-related test in almost half a decade.
Formerly used to test Falcon 9 first stages before SpaceX built a new stand for Falcon 9 and Heavy, that tripod stand has been reactivated for the sole purpose of supporting vertical Raptor engine static fire testing, which Musk says will simplify and expedite development by making test conditions much more flight-like. As of now, all subscale and full-scale Raptor engine static fire testing has been performed at horizontal test stands in McGregor, apparently resulting in wear and behavior that would not likely appear if engines were tested vertically.
SpaceX has gone through the same process with its Merlin engine programs, beginning with horizontal testing (far easier and simpler) but ultimately building a number of dedicated vertical test bays to ensure that engine acceptance and development tests can be performed under more flight-like conditions.
According to NASASpaceflight, SpaceX may have already fired up Raptor SN15 on its reactivated tripod test stand earlier this week, kicking off Raptor’s first Starhopper-free vertical static fire testing. It’s now unclear where the twin horizontal Raptor test bays will fit into future engine testing given Musk’s comments. More importantly, every completed Starship and Super Heavy rocket will require several dozen new Raptor engines and every one of those engines will likely need to pass acceptance testing (including static fires) in McGregor before they can be installed on a launch vehicle.
SpaceX’s Falcon 9 rocket already requires 10 engines per new booster and upper stage, a test burden SpaceX has only managed with the help of two Merlin 1D stands and one Merlin Vacuum stand, all vertical. In other words, it’s safe to say that the reactivated tripod stand is likely just the first of several vertical Raptor test stands to come.

SpaceX’s $24B Starbase supercomputer plan slipped past a key roadblock
SpaceX wants a Starbase tax break for a $24 billion gas plant and supercomputer campus.
SpaceX is asking its own company town for a tax break on a $24 billion natural gas power plant and supercomputing facility at Starbase, Texas, and the land it picked sits just outside the reach of a data center moratorium that took effect in neighboring Brownsville last week.
A City of Starbase public hearing notice says SpaceX “proposes to construct, own, and operate a gas-fired power plant and super-compute facility” on roughly 444 acres between Boca Chica Boulevard and the Port of Brownsville. The $24 billion figure covers only the initial phases, and the notice leaves room for future expansions. The Starbase City Commission will consider a property tax abatement and a related economic development agreement at a 7 p.m. hearing on December 9. The notice does not disclose the size or length of the abatement, or how much computing capacity the site would hold.
The location has a history. Over the summer, SpaceX asked Brownsville to remove the tract from its city limits and offered $220 million for water and wastewater projects in return. Brownsville approved the move in August, and Starbase later annexed the land. Brownsville’s own 90-day pause on data center applications took effect last week, and had the tract stayed inside the city, the project likely would have needed a different home.
The power side is already in front of state regulators. SpaceX has applied to the Texas Commission on Environmental Quality for air permits covering 35 mobile gas turbines producing roughly 750 megawatts, according to Politico, which also noted that two of the three Starbase commissioners voting on the incentives are SpaceX executives.
Building its own plant lets SpaceX skip the Texas grid. Gov. Greg Abbott paused new data center grid connections in August pending an audit, but a facility that generates its own electricity does not need one. The air permit still has to clear the TCEQ, where Abbott also ordered a halt on data center permits.
The bigger test arrives in January. Governor-elect Gina Hinojosa, who unseated Abbott last week, has said she will block data center approvals until the legislature passes new protections, and she has already asked state officials to hold off on any sale of Boca Chica State Park to SpaceX until she is sworn in. Tesla and SpaceX shares both fell the day after the election, and Musk’s first reaction on X was “Data centers in space looking pretty appealing right now.”
That line points to Starmind, SpaceX’s orbital compute constellation. Musk has said terrestrial compute will be “peanuts compared to orbital compute” and expects monthly orbital deployments to pass ground deployments around the end of 2028, as Teslarati reported. Until then, SpaceX still needs gigawatts on the ground. It ended the third quarter with 1.7 GW of nameplate compute, is targeting 2.5 to 3 GW by the end of this year and wants at least 10 GW more in 2027. Its existing Colossus sites around Memphis already run on gas turbines and face a lawsuit from residents over emissions.
Local reaction is split. The South Texas Environmental Justice Network has announced a protest, citing air quality, water use and energy bills, while some Brownsville residents told the Tribune they welcome the jobs. SpaceX did not respond to the Tribune’s questions about the project.
Tesla CEO Elon Musk announced that the company will extend Cybertruck production slightly to handle its extensive order backlog.
On Wednesday, Musk announced that “In order to work through more of the Cybertruck order backlog, production will be extended through the end of summer 2027.”

Tesla has already attempted to simplify its last months of production for the Cybertruck by eliminating several trim levels and only offering the Cyberbeast, the most expensive trim that starts at $109,990. The other two trim levels, the Cybertruck All-Wheel-Drive and Premium All-Wheel-Drive have both been discontinued.
There has been plenty of backlash against Tesla’s decision to ax the Cybertruck, but the company’s forecast prioritizes Cybercab and autonomy. Factory space at Gigafactory Texas that is not necessary is now being set aside for the Cybercab as the company truly embraces its “transportation-as-a-service” model.
There is still a slim chance the Cybertruck survives. Last evening, Tesla upfitter Unplugged Performance offered to take the Cybertruck line off of Tesla’s hands and continue building it, along with a CyberSUV.
Nevertheless, Tesla seems to be ending the Cybertruck on its terms after what will be a three-and-a-half-year run. It still does not really feel quite real; I think many of us thought the Cybertruck would be around for years to come.
Musk added more detail, stating that while it was not the smartest move, “there must be some room in this world for sentimentality or what’s the point?”
This is not the smartest move from a profit-maximizing standpoint btw, but there must be some room in this world for sentimentality or what’s the point?

Other EV pickups on the market have experienced a similar fate.
The Ford F-150 Lightning was axed by the Detroit company due to the continued losses the company took from sales. That truck was never profitable, and Ford is still taking a quarterly loss in its EV side. However, things are moving along as it has plans for a mass market EV pickup, which will likely gather some substantial demand if Ford can get it just right.
Perhaps another extension or even a total change of heart might come. Only Musk knows.
In a sudden and closely watched milestone, Tesla Robotaxi has edged past Waymo on the Texas Department of Motor Vehicles automated vehicle registry. As of November 10, Tesla lists 1,302 registered vehicles under Tesla Robotaxi, LLC, compared with Waymo’s 1,297.
The flip is narrow, but real, according to the State’s books. Tesla’s Texas fleet, following an expansion on November 10, now consists of 729 Model Ys and 573 purpose-built Cybercab vehicles. Waymo’s roster is dominated by the Jaguar I-PACE and a growing number of Zeekr-based Ojai minivans.
NEW: Tesla Robotaxi just added 20 Tesla Model Ys to its fleet. The Texas fleet now stands at 1302 vehicles.

Those figures come from the same public TxDMV automated vehicle listings that independent trackers have monitored since a Texas law required operators to disclose fleet sizes.
The scale of Tesla’s climb is pretty interesting and shows how much the company has grown its autonomous ride-hailing fleet over the past months. When the registry first became public in late May 2026, Tesla listed just 42 vehicles on it. Meanwhile, Waymo had several hundred vehicles registered to it.
Tesla CEO Elon Musk shades Waymo: ‘Never really had a chance’
Since then, Tesla has multiplied its authorized Texas fleet more than thirty times, driven by repeated Model Y additions and a steady build of Cybercabs. Waymo has also expanded, but at a slower pace than Tesla.
It is also important to note that registrations are not necessarily equal to operational fleet. The TxDMV list shows the number of vehicles each company is permitted to run, but it does not report how many are actively carrying riders, which cities they serve, or trip volume. Both companies stage vehicles and run mixed fleets that can include units in testing or temporarily offline.
A lead on the registry therefore signals capacity and regulatory positioning more than immediate ride volume.
Tesla has use the growing authorized fleet to expand its unsupervised service beyond the original Austin geofence area, as now it is flowing into cities like San Antonio and Dallas. The company has highlighted plans for a broader Cybercab deployment, eventually into new states and territories.
Waymo is operating across multiple Texas markets and in other areas of the United States.
Right now, the five-vehicle margin is thin and could reverse with the next large registration from either side. For the moment, however, the public Texas record shows Tesla holding the larger authorized Robotaxi fleet in the state.
