SpaceX Texas test HQ fires up a dozen Falcon, Starship rocket engines in six hours
Though it often falls under the radar relative to SpaceX’s high-profile Boca Chica Starship hub, another even more important Texas outpost appears to be busier than ever testing the rocket engines and boosters instrumental to all SpaceX operations.
Famous for occasionally supporting half a dozen or more rocket tests on busy days, SpaceX’s McGregor, Texas facilities showed off exactly that kind of rapid-fire activity on Friday, March 19th, flexing the sheer variety and volume of rocket hardware liable to pass through its gates.
Located on the grounds of a former US military explosives factory, SpaceX’s McGregor, Texas rocket development and test facilities have been testing Falcon, Dragon, and Starship parts and supporting each program’s development for a decade and a half. After being fabricated and assembled in Hawthorne, California, virtually every single active propulsive component SpaceX has ever flown has spent some amount of time in McGregor.
For boosters, every cold gas maneuvering thruster is qualified in Texas before being sent back to Hawthorne for final installation. Each stage’s nine Merlin 1D engines are individually tested in McGregor, shipped back to Hawthorne, installed on a booster, shipped back to McGregor, and static fired as an integrated first stage before SpaceX deems a Falcon 9 or Falcon Heavy core ready for flight. The exact same process (separate engines and thruster qualification followed by integrated vehicle testing) is performed with Falcon upper stages and their Merlin Vacuum engines, as well as all Dragon spacecraft and their Draco (and SuperDraco) thrusters. The same is true for the two Raptor engine variants and cold-gas thrusters that power Starship.
On March 19th, nearly all of those different engines and vehicles – and the separate stands used to test each of them – came together for an exceptionally busy day at McGregor. According to local resident Reagan (@bluemoondance74), who lives within earshot of SpaceX’s extraordinarily busy rocket testing HQ, at least five unique tests were performed in just six hours – all but one of which was squeezed into the last ~125 minutes.
Around 2:40 pm, an unknown test – possibly a Merlin Vacuum (MVac) or Merlin 1D (M1D) engine – kicked off the salvo. Four hours later, SpaceX completed arguably the most significant test of the day, firing up the first Falcon Heavy center core to head to McGregor in almost 24 months. Assuming that static fire was a success, the booster will be inspected, have its tanks cleaned, and be shipped to Florida to complete the first stage of SpaceX’s fourth Falcon Heavy rocket for a launch as early as July.
An hour and a half after the Falcon Heavy center core’s static fire, SpaceX fired up a Raptor engine (either a sea level or vacuum variant), followed by another likely M1D or MVac test just minutes later. Finally, at 8:52 pm, SpaceX ignited a second Raptor engine at an entirely separate vertical test stand (known as the tripod stand) recently modified to support testing Starship engines in a more flight-like configuration. Altogether, assuming no repeated tests, SpaceX effectively tested a booster and 13 (9+4) rocket engines in a little over six hours.
More likely than not, one or both of those Raptors will soon find themselves on a Starship or Super Heavy prototype in Boca Chica. The M1D and/or MVac engines will assuredly find a place on a future Falcon booster or upper stage. The Falcon Heavy center core (B1065 or B1066) is scheduled to launch as early as July 2021 and will be the first of its kind to fly in an intentionally expendable configuration. Another Falcon Heavy center core – possibly B1067 – will likely also find itself in McGregor within the next few months for the rocket’s fifth launch, scheduled no earlier than (NET) October 2021.
All told, SpaceX’s McGregor rocket testing HQ is about as busy as – if not busier than – it’s ever been as the company works towards an unprecedentedly ambitious 48-launch 2021 manifest, builds and flies at least four Dragon spacecraft, and pursues an even more ambitious effort to begin orbital Starship launches this summer. Quieted away in rural Texas, McGregor may largely go unnoticed but its infrastructure remains as integral as ever for virtually every single SpaceX project – past, present, and future.

Earnings call updates
The following are live updates from Tesla’s Q3 2025 earnings call. I will be updating this article in real time, so please keep refreshing the page to view the latest updates on this story.
16:25 CT – Good day to everyone, and welcome to another Tesla earnings call live blog. The Q3 2025 Update Letter seemed to be on the quieter side, but it’s hard not to be impressed with Tesla’s $4 billion free cash flow, an all-time high.
Now we just have to see how the earnings call will go.
16:30 CT – Looks like the earnings call’s livestream is up. It hasn’t started yet, but the music’s on. Here’s the livestream:
16:33 CT – One of the most fun things about Tesla earnings call coverages is that you don’t really know what type of Elon Musk you’re gonna get. The questions from investors and analysts are always fun too.
16:35 CT – And here we go. Travis Axelrod takes the floor and introduces Tesla’s executives.
16:36 CT – Elon’s opening remarks begin. He says Tesla is at a critical point because real-world AI is imminent. He states that he believes Tesla has the highest intelligence density. “It’s gonna be like a shockwave,” Elon said, highlighting that there are millions of cars out there that could become full self-driving with a simple software update.
16:38 CT – With Tesla achieving clarity on Unsupervised FSD, Musk stated that he feels “confident in expanding Tesla’s production.” He also noted that Tesla Energy is rising quickly, especially with products like the Powerwall and the Megapack. “We see the potential there for Tesla battery packs to improve the energy output per year of any given grid, the US or otherwise.”
16:40 CT – Elon also reiterated his prediction that Tesla Optimus could be the largest product in the world. A good reason for this is the fact that Tesla has scale, Musk stated. Musk also stated that it’s easy for users in the United States to test out FSD V14 for themselves. He also mentioned that Tesla is currently hard at work with Megapack 4.
“We look forward to unveiling Optimus V3 in Q1. I think it will be quite remarkable,” Musk said, adding that V3 will almost seem like a person in a robot suit.
16:45 CT – Musk summed up his opening remarks with a comment on Tesla’s updated mission.
“In conclusion, we’re excited about the updated mission of Tesla, which is sustainable abundance. We’re going beyond sustainable energy. We believe that with Optimus and self-driving, we can actually create a world where there is no poverty, where everyone has access to the finest medical care.
“Optimus will be an incredible surgeon. Imagine if everyone had access to an incredible surgeon. I think we’re headed to sustainable abundance, and I’m excited to work with the Tesla team to make that happen,” Musk said, summing up.
16:48 CT – Tesla CFO Vaibhav Taneja discussed the company’s rollout of its expanded Model Y lineup such as the Model Y L, as well as the advantages of the Robotaxi network. He also confirmed that Tesla is looking to secure approvals for FSD tests in several areas across the globe.
He also discussed Tesla’s regulatory credits. “”While regulatory credits declined sequentially, we entered into new contracts and delivered on previous contracts,” he said.
16:54 CT – Investor questions are asked about demand for Megapack and Powerwall. Tesla noted that Tesla is seeing a lot of interest and demand for Megapack and its related products. There is also a surge in demand for residential batteries.
Looks like the Tesla Solar Roof is coming alive as well.
16:59 CT – A question about the challenges of Optimus’ rollout was asked. Elon Musk noted that bringing Optimus to market would not be a walk in the park. It will be a very difficult endeavor. “It’s an incredibly difficult thing,” Musk said, adding that the hands of Optimus are very difficult to design and produce due to its complexity.
Tesla is really putting a ton of work on Optimus’ hands, likely because the robot will need to be very dexterous to be useful in both residential and industrial applications. He noted that for Optimus to be successful, Tesla must really be vertically integrated.
Elon also mentioned that Optimus is one of the reasons behind his goals with his 2025 compensation plan. He needs control of Tesla if the company is building a literal robot army.
17:05 CT – A question about Tesla’s chip deal with Samsung. Elon noted that he has nothing but good things to say about Samsung. He then clarified that Tesla will be focusing both TSMC and Samsung on AI5.
“The AI5 chip design by Tesla is an amazing design. I have spent every weekend for the last few months with the chip design team working with AI5,” Musk said. “By some metrics, the AI5 chip will be 40x better than the AI4 chip.” This is because the hardware is designed for Tesla’s software stack.
There is also a lot of efficiencies and deletions that have been implemented on AI5. “This is a beautiful chip,” Musk said, reiterating that both Samsung and TSMC will be producing AI5. Tesla wants an oversupply of AI5 chips. If there’s an oversupply, Musk said that the chips could just be used for training in Tesla’s data center.
17:09 CT – A question was asked about Tesla abandoning HW3 was asked. The CFO stated that Tesla is not abandoning HW3. “We will definitely take care of you guys,” he said, adding that he himself is driving a HW3 car. Tesla executives also noted that the company is developing a V14 “Lite” for HW3 cars.
17:13 CT – A question about the Tesla Semi’s autonomy was asked. Tesla noted that things are progressing with the Semi program. Analyst questions now begin. First up is Wolfe Research, which asked about Elon’s comment about Tesla now focusing on volume with FSD now developed.
Elon Musk responded that Tesla’s capacity today is not at 3 million cars yet, but Tesla can probably achieve that level in 24 months or less. “We’re gonna expand production as fast as we can, and as fast as our suppliers can keep up with it,” he said.
He added that the Cybercab will be a big project since it’s a your de force of engineering optimization due to its driverless nature. He also stated that Cybercab production will start in Q2 2026.
17:21 CT – Barclays asked about markets that are outside of Tesla’s core competencies. Elon noted that Tesla had zero core competency when it started. He highlighted that Tesla today is still a bunch of startups that are working together. He did also state that “Optimus at scale is an infinite money glitch” since it could 5X a person’s productivity.
17:27 CT – Lightshed asks about the Robotaxi program and the removal of safety drivers in Austin by year end. Musk noted that Tesla will be very cautious with FSD’s rollout. He noted that Tesla will be paranoid about safety. He noted that Tesla typically rolls out its FSD updates with safety at the forefront, so first builds of a major release tend to be safe but not as smooth.
“This car will feel like a living creature,” Musk reiterated, adding that Teslas will eventually be able to find parking spots on their own intelligently.
17:34 CT – Oppenheimer asked about the timeline of Optimus production. Musk noted that the hardware design of Optimus will not be frozen even after the humanoid robot starts its production. “We’ll have a production-intent prototype ready to show in Q1,” Musk said, adding that hopefully, Optimus will enter production late next year.
17:37 CT – Questions for this earnings call are done, and in closing, the CFO urged shareholders to vote on the Board’s recommendations. Tesla’s future depends on it.
17:41 CT – And that wraps up Tesla’s third quarter 2025 earnings call! Thank you so much for following along as we covered this event. Until the next time!

Tesla’s new Safety Report shows Autopilot is nine times safer than humans
Tesla released its Vehicle Safety Report for Q3 2025, and it showed that one crash was recorded every 6.36 million miles drive in which drivers were using Autopilot technology.

Tesla’s new Safety Report for Q3 shows Autopilot technology contributed to accident frequency that was nine times lower than the national average.
Tesla released its Vehicle Safety Report for Q3 2025, and it showed that one crash was recorded every 6.36 million miles drive in which drivers were using Autopilot technology.
This is a stark contrast from the most recent data made available by the National Highway Traffic Safety Administration (NHTSA) and Federal Highway Administration (FHWA), which shows there is an automobile crash approximately every 702,000 miles.
Autopilot & FSD Supervised safety data
In Q3 2025, we recorded 1 crash for every 6.36 million miles driven in which drivers were using Autopilot technology

The figure for Q3 2025 is slightly lower than the one that Tesla released in Q3 2024, which eclipsed 7 million miles between accidents for drivers using Autopilot technology.
Over the past seven quarters, Q1 has been Tesla’s strongest showing with the Vehicle Safety Report, with Q4 being the weakest. This is usually attributed to weather and driving conditions deteriorating toward the end of the year.
Q1 2024 was Tesla’s best performance so far, with one crash every 7.63 million miles.
Autopilot and Full Self-Driving have been a major focus of Tesla over the past few years, and recent versions have improved on what has already proven to be an extremely safe way to travel, as long as it is used correctly.
Tesla’s Full Self-Driving (Supervised) suite is a suitable way to allow the vehicle to navigate through any traffic setting and has been widely effective for day-to-day travel. With the data Tesla gets from its use across its vehicle fleet, it gets more refined and more accurate with every passing mile.
The company has teased the potential for completely unsupervised Full Self-Driving releases in the future, but Tesla has to solve autonomy before it can offer anything like that to the public.
