SpaceX has transported (half of) its Starship Mk1 prototype to its South Texas launch pad for the first time ever, signifying that the company is about to enter a major new stage of testing.

The move, however, raises the question: why is SpaceX transporting only half of Starship Mk1 to the launch pad?

Following SpaceX CEO Elon Musk’s September 28th presentation on Starship, the spacecraft prototype was partially disassembled, having essentially been mocked up to stand as a backdrop at the event. The impact was fairly minor, taking up no more than a few days of work, but Starship Mk1 remains in two large, separate pieces – a curved nose section and the ship’s cylindrical propellant tank and propulsion section.

A little over a month after Musk’s presentation, SpaceX technicians freed Starship Mk1’s lower tank section from a steel mount and temporarily installed the giant half-spacecraft on framework mounted to a Roll Lift transporter. SpaceX has consistently relied on Roll Lifts for the task of transporting Starship’s massive segments both around and between its Boca Chica, Texas build and launch facilities. This time around, only Starship Mk1’s lower half was loaded onto the transporter before being staged overnight near the main gate of SpaceX’s build site.

Although work continued throughout the night, around dawn on October 30th, transport activity restarted in earnest, with technicians preparing to move Starship. A road closure filed with Cameron County suggested that something would occur on the 30th, with followers speculating that Starship Mk1 would be transported to SpaceX’s South Texas launch pad. As it turned out, that speculation was correct, and (half of) Starship Mk1 was indeed moved to the launch pad and installed atop a new launch mount that was built from scratch in just a few months.

(Half a) Starship on the pad

While it’s undeniably thrilling to see Starship Mk1 head to SpaceX’s Boca Chica launch pad for the first time ever, it remains to be seen why exactly only half of the rocket was transported – no mean feat. Although a great deal of progress has been made over the last month outfitting Starship Mk1 with all the wiring, electronics, plumbing, and other subsystems the prototype will need to function, it’s plainly visible that a significant amount of work remains before Starship will be ready for integrated testing.

Most notably, as pictured above, the launch mount frame is certainly more or less complete, but most of the complex plumbing, wiring, and power equipment it will need to serve its function is not obviously present. There is admittedly a possibility that SpaceX will reuse the ‘quick disconnect’ umbilical ports used by Starhopper on Starship Mk1, but that remains to be seen.

Starship Mk1 itself has a ways to go before it will be ready for integrated testing. Near the orange plastic is what is believed to be a large propellant feed line, needed to fuel Starship. Those lines have yet to be closed off. (NASASpaceflight – bocachicagal)

Additionally, Starship Mk1 also has some level of work left before it will be ready for its first propellant loading test, let alone flight. Aside from a large amount of wiring and avionics that still needs to be partially run, harnessed, and connected, Starship’s main liquid oxygen and methane feedlines – needed to fuel the rocket – are largely complete but still unfinished.

There are at least a few obvious possible explanations for SpaceX moving the Starship Mk1 tank section to the launch pad in its partially-finished state. The easiest explanation is that SpaceX wants to perform leak and pressure tests of Starship’s tanks as early as possible, even if that involves testing the rocket without its nose (the host of Mk1’s batteries, power controllers, COPVs, pressurization tanks, and more). It’s not clear that Starship Mk1 is – at present – capable of performing a wet dress rehearsal (WDR), a common aerospace test where a rocket is fully fueled and counts down to launch without actually igniting.

Starhopper performed several wet dress rehearsal tests before its final 150m flight test in August 2019. (LabPadre, 07/14/19)

Instead, SpaceX could potentially perform a pressure (or at least leak) test with a neutral gas (or perhaps liquid nitrogen) just to verify that Starship Mk1 is structurally sound before kicking off cryogenic propellant loading. Additionally, it’s possible that SpaceX could get around Mk1’s incomplete propellant feed lines by attaching pad umbilicals directly to the ends of the incomplete feed lines.

At the same time, it’s possible that SpaceX has decided to finish assembling Starship at the launch pad itself, hinted at when a local photographer captured a number of Mk1’s control surfaces and aero covers being moved around shortly after Starship was moved to the pad. Time will tell. For the time being, SpaceX has no more road closures scheduled (meaning no nose section transport) until November 7th and 8th, followed by another on the 12th.

Tesla’s flying Roadster just revealed something bigger than the car

Analysts say the Roadster demo puts a Tesla and SpaceX merger back on the table.

The Roadster unveiling near Waco ended Thursday night, and by Friday morning much of the investor reaction had less to do with the car than with who owns the rocket technology inside it.

Wedbush analyst Dan Ives said the event “puts the Tesla/SpaceX relationship on the table in a tangible way,” pointing to the propulsion, pressure vessel and control hardware sitting on a Tesla product. Gene Munster of Deepwater Asset Management called the demo “a ridiculous display of engineering” with “no commercial value” beyond embarrassing traditional automakers, though he said it showed Musk wants the two companies together.

The more specific forecast came a day earlier from Barclays. Analyst Dan Levy told clients a deal could be announced before Tesla’s annual meeting, which must happen by December 6, and that an announcement in late October or early November could make shareholder approval harder. Barclays expects SpaceX to be the buyer in an all stock deal, with Tesla holders receiving SpaceX shares at a premium, based on market values of roughly $2.1 trillion for SpaceX and $1.5 trillion for Tesla. If nothing lands around the meeting, the bank still sees an announcement within 6 to 12 months.

The Roadster demo just added more weight to merger speculations. Tesla’s demo used cold gas thrusters and pressure tanks of the kind SpaceX uses on Falcon 9, and Musk described the car as a collaboration between Tesla and SpaceX engineers, as we mentioned in our breakdown of the three Roadster configurations.


Musk has not publicly addressed a deal since the event, as far as we have seen. His most direct answer remains the one he gave at the All In Summit, when he said that with so much collaboration, “who can imagine what action one might take” without ruling anything out. Ives has held to a 2027 timeline since his March note, and Musk pushed back on the China piece of the speculation when ARK floated a year end announcement in August.

The next test is Tesla’s third quarter earnings call on October 21. However, we recall in July that Musk told analysts, “we can’t talk about combining companies and that kind of thing on an earnings call,” so a clear answer wouldn’t be expected.

How Tesla’s Roadster fan system and thrusters are built to dominate the corners

Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.

Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.

That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.


Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds

The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.


Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”

There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds

Tesla’s Roadster comes in Performance, Thrust and Rocket versions, with a claimed 0-60 under 0.59 seconds.

Tesla finally showed the next generation Roadster on Thursday night, and the demo had more in common with a SpaceX test than a track lap. At an event outside Waco, Texas, near SpaceX’s McGregor site, the car used a mix of fans and cold gas thrusters to drive up a curved ramp until it was upside down, then flew off, flipped and landed on the pavement. “Well, it worked,” Elon Musk said. “Flying cars are real.”

The Roadster also hovered itself over a Cybercab, Cybertruck, Tesla Semi, Model Y and Model 3 while moving, and that Tesla showed it going 0 to 60 mph in one second. Musk said “this will be the actual car that’s on the roads” and that it “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. He called the result a collaboration between Tesla and SpaceX engineers that is “better than any James Bond car,” with Franz von Holzhausen and Lars Moravy on site.

Tesla published new mind-blowing stats for the car that replace the previous targets. The Performance version is road ready and seats two, with active aerodynamics and a multi-mode suction system, and Tesla lists 0 to 60 mph in under 1.6 seconds. The Thrust version is race ready, also seats two, and adds rear-mounted cold gas thrusters for a 0 to 60 time of under 0.9 seconds. The Rocket version is described as air ready, seats one, and uses perimeter-mounted thrusters for forward and upward acceleration plus lateral rotational movement.

Configuration Seats 0 to 60 mph
Performance 2 under 1.6 s
Thrust 2 under 0.9 s
Rocket 1 under 0.59 s

Tesla’s own description: “So…yes, it can fly.” It lists a 0 to 60 time of under 0.59 seconds for Rocket, a top speed of up to more than 230 mph, and range of more than 300 miles. Tesla has not yet given pricing in the information we have seen, but has reopened $50,000 reservations in the newly updated Tesla Roadster configurator. Production is planned for Giga Texas in 2027 or 2028, and Musk has said it would follow the demo by 12 to 18 months.

Tesla’s Roadster page adds more on how the car works. A multi-mode fan and ground sealing system pulls air from under the car, producing enough suction to hold it upside down even when stationary. Active wings, steer-by-wire with a yoke, and a Track Mode that lowers the car round out the driving setup. The cold gas thrusters use all-electric actuators for micro adjustments to stabilize the car in flight. Tesla says it cut weight with magnesium, titanium and carbon fiber, manual controls and a fixed seat position, and the exterior has hidden headlights, a full-length taillight and Ano White paint inspired by aerospace coatings. Inside are an Ultrawhite interior with gray microsuede, a center touchscreen and two smaller forward displays, and gold tinted glass modeled on spacesuit visors. Availability is tiered: Performance is by reservation, Thrust is a limited release, and Rocket is invite only. Tesla notes the car is not approved for public road use, and that Rocket is not available in all regions.

Musk has described the Roadster as “the best of the last of the human-driven cars,” and he has been open that it is a halo product. He said he is “not sure it moves the needle massively from a revenue standpoint,” and has warned that anyone whose top priority is safety should not buy it. Tesla reports third quarter earnings on October 21.
