SpaceX's new Starship test stand to make life a little easier for Raptor engine engineers

SpaceX recently debuted a new rocket engine test stand at its Central Texas development facilities and one specific aspect of the so-called ‘tripod stand’ could make life a lot easier for Starship’s Raptor engine engineers.

The success of SpaceX’s extremely ambitious Starship spacecraft and Super Heavy boosters hinges heavily on the prior success of a next-generation rocket engine the company is developing itself. Known as Raptor, the engine is likely one of the most complex ever developed, owing to its use of a combustion cycle that’s as challenging and unforgiving as it is efficient. That efficiency is the draw.

The decision to base the Starship launch system around methane and oxygen propellant – relatively dense, safe to handle, and easy to generate on Mars – means that it can never be as efficient as a rocket based on hydrogen and oxygen, the pinnacle of chemical combustion-based propulsion. For a methalox rocket as nominally reusable as Starship, going to extremes to eke even a smidge of extra efficiency out of its Raptor engines is a reasonable – if not necessary – decision. However, that pursuit of efficiency carries many hurdles with it, some of which can even be exacerbated by the equipment used to test those engines on the ground.

Raptor is less than unique in this particular case but SpaceX’s engine development and testing has matured to the point that the stands it’s relied on for static fires have become a detriment to the engine’s progress. Specifically, aside from Starhopper, all previous Raptor static fires have been performed with engines installed horizontally in test bays located at SpaceX’s McGregor, Texas development facilities. While in flight, Raptor engines will theoretically never experience wear and tear similar to the unique conditions imposed by horizontal testing – engine burns will almost invariably exert forces along a vertical (up and down) axis.

To almost anyone else, even other engine development companies, this might seem like an insignificant difference. Built around the full-flow staged combustion (FFSC) cycle and meant to be unprecedentedly reusable and reliable, the Raptor engine is not quite as forgiving. Since the engine’s inaugural full-scale static fire test just one year ago, SpaceX CEO Elon Musk has noted several times that Raptor could benefit from new vertical test stands.

Speaking in October 2019, Musk stated that a new vertical test stand would “hopefully allow simplification of Raptor design, as pump shaft wear & drainage is better in vertical config.” More generally, testing Raptor engines vertically would also be “more representative of flight [conditions]”, allowing SpaceX to live up to its proven “test as you fly” philosophy.

Indeed, aside from Starhopper’s two successful test flights and a handful of static fires, Raptor has performed barely any vertical testing despite more than 3200 seconds of static fires completed with 18 full-scale engine prototypes in the last 12 months alone. Including subscale engines tested from 2016 through 2018, SpaceX’s Raptor engine has likely completed some 5000 seconds (>80 minutes) of test fires over the course of three and a half years of development.

Aside from allowing SpaceX engineers to potentially simplify the Raptor engine design and test the Starship engines in conditions much closer to what they will experience in flight, the addition of a new dedicated test stand – on top of two existing horizontal bays – should allow even more testing to be done in a given time-frame. The more testing that can be done, the more engines SpaceX can quickly qualify for flight, and given that every Starship/Super Heavy pair could require up to 43 new Raptor engines, SpaceX will need all the testing capacity it can get.

SpaceX achieved its 100th Starlink mission of the year on Friday, October 31, marking another milestone for 2025. 

A Falcon 9 rocket carrying 28 Starlink broadband satellites successfully lifted off from Vandenberg Space Force Base in California at 4:41 p.m. ET, carrying another 28 Starlink satellites to Low Earth Orbit (LEO).

Falcon 9 booster’s 29th flight

Roughly 8.5 minutes after liftoff, the Falcon 9’s first stage touched down on the drone ship Of Course I Still Love You in the Pacific Ocean. This marked the booster’s 29th flight, which is approaching SpaceX’s reuse record of 31 missions.

This latest mission adds to SpaceX’s impressive 138 Falcon 9 launches in 2025, 99 of which were dedicated to Starlink, according to Space.com. The company’s focus on reusing boosters has enabled this breakneck pace, with multiple launches each week supporting both Starlink’s expansion and external customers.

Starlink’s network continues massive global expansion

Starlink remains the largest active satellite constellation in history, with more than 10,000 satellites launched, nearly 8,800 of which are currently active. SpaceX recently achieved Starlink’s 10,000-satellite milestone. With 100 Starlink missions completed for 2025, space enthusiasts have noted that SpaceX has successfully launched 2,554 Starlink satellites so far this year.

Tesla shares updated timeframe for Cybertruck FSD V14 release

The Cybertruck was expected to receive FSD V14 before the end of the month, but Tesla was not able to meet the target.

Tesla’s Full Self-Driving (FSD) V14 update for the Cybertruck could arrive this weekend, as per recent comments from Director of Autopilot Software and VP of AI Ashok Elluswamy. 

The Cybertruck was expected to receive FSD V14 before the end of the month, but Tesla was not able to meet the target.

Cybertruck FSD V14

Considering the extended wait for FSD V14, it was no surprise that several Cybertruck owners were asking for updates about the system’s rollout to the all-electric pickup truck on Friday. These included the official Cybertruck X account, which responded to Elluswamy’s end of month estimate with “I only see trick. Where is my treat.” 

This prompted a response from the AI executive, who replied with, “Sorry, pushing for early access Cyber release over the weekend.” This means that if all goes well, Cybertruck owners would be able to experience FSD V14 very soon. Some, however, are wondering if Tesla would go straight to V14.2 for the Cybertruck’s FSD V14 update, or if the vehicle will receive V14.1 first. 

Tesla pushes to unify FSD experience across its lineup

The upcoming Cybertruck rollout represents the next step in Tesla’s efforts to roll out FSD capabilities across all of its vehicles. FSD V14 is a notable step forward for the company’s AI-driven self driving system, with features like Mad Max mode getting positive reviews from longtime Full Self Driving testers.

For the Cybertruck, the FSD V14 update would mark one of its first major over-the-air upgrades for the vehicle. Likely due to its size, the Cybertruck tends to receive FSD updates later than the S3XY lineup, which is quite surprising considering that the all-electric pickup truck is a premium-priced vehicle that is home to some of Tesla’s most advanced technologies.

Tesla has launched a new service designed to make its Full Self-Driving (FSD) technology familiar to all commuters. 

Dubbed the “Tesla Ride” program, the initiative aims to bring supervised Full Self-Driving demos and Grok AI-guided experiences to consumers in real world trips. 

How Tesla Ride Works

As per the official Tesla Ride website, the session will allow participants to sit in the driver’s seat while a Tesla Advisor rides shotgun as co-pilot. The Tesla Advisor then guides riders through the company’s latest supervised FSD features, comfort settings, and in-car entertainment. Participants would also be able to interact with Grok AI in the vehicles. Grok will be capable of answering questions during the ride, and it will even tell stories along the way.

Tesla noted, however, that Tesla Ride sessions are capped at 45 minutes each, and it requires participants to have a valid driver’s license and insurance. Interested participants are also advised to call beforehand so they can schedule their Tesla Rides.

Marketing push and reach

The Tesla Ride program runs across several markets from October into November, and in some locations into the end of December 2025. Participating states are numerous, from Michigan to Virginia to Illiois, Nevada, and California, among others. A look at the official webpage for Tesla Ride shows that the company is still taking a very cautious approach with the program, with disclaimers clearly stating that FSD Supervised does not make Teslas autonomous just yet.

Tesla’s focus on safety with FSD was highlighted recently by Senior Vice President for Automotive Tom Zhu. “Elon said it in 2021: “For self-driving, even if the road is painted completely wrong and a UFO lands in the middle of the road, the car still cannot crash and still needs to do the right thing. 

“The prime directive for the autopilot system is: Don’t crash. That really overrides everything. No matter what the lines say or how the road is done, the thing that needs to happen is minimizing the probability of impact while getting you to your destination conveniently and comfortably,” the executive stated.
