SpaceX begins Starship launch mount installation at historic Pad 39A in Florida
At the same time as SpaceX’s Boca Chica, Texas team is working around the clock to prepare Starship Mk1 for several major tests, the company is building a second dedicated Starship launch complex at Pad 39A and as of November 4th, that construction effort has reached a symbolic milestone.
According to photos taken by local resident and famed rocket and ship photographer Julia Bergeron on a bus tour of Kennedy Space Center (KSC), SpaceX has officially begun to install a large steel structure at Launch Complex 39A, a pad the company has leased from NASA since 2014. Known as a launch mount, the massive structure will one day support SpaceX’s first East Coast Starship and Super Heavy static fires and test flights.

At SpaceX’s Boca Chica, Texas Starship facilities, the company has already made a huge amount of progress fabricating and outfitting a brand new launch mount that will soon support Starship Mk1’s first propellant loading, static fire, and flight tests. The spartan steel structure looks different from anything SpaceX has built in the past for Falcon 9 and is equally unrecognizable alongside the renders of a finished-product launch pad included in an updated Starship launch video.
What is undeniable, nevertheless, is the speed with which technicians have taken the Texas launch mount from a group of unconnected, partially-finished parts to a nearly complete structure with the business half of Starship Mk1 installed on top. SpaceX workers have built the mount, completed a large amount of plumbing to connect it to nearby liquid oxygen, methane, nitrogen, and helium reserves, and installed Starship on the mount in less than two months. The final integration of different prefabricated pieces began barely a month before Starship was moved to the pad, as pictured below.


Two pads, two approaches
Although Boca Chica’s launch mount is quite large, based on Julia’s photos of Pad 39A, Florida’s nascent launch mount is going to be significantly bigger. The section that SpaceX began installing in the first days of November appears already be much taller than the mount in Texas, and it also looks more like a rectangular corner than anything resembling part of Boca Chica’s hexagonal structure.
At the same time, the apparent rectangular corner being worked on in Florida would be a much better fit for the partially-enclosed launch mount structure shown in SpaceX’s official 2019 Starship launch video.

This is all to say that it looks like SpaceX is taking significantly different approaches with its two prospective Starship launch sites, which should come as no surprise in the context of the Starship program. SpaceX is already competitively building multiple Starship prototypes at two separate facilities in Boca Chica, Texas and Cocoa, Florida, a competition that has already produced visible differences between Mk1 and Mk2 prototypes. There’s a good chance that SpaceX intends to preserve that competitive atmosphere with Starship’s launch facilities, not just the rocket itself.
Additionally, it’s clear that Texas and Florida currently serve very different roles in the actual testing of Starship prototypes. Boca Chica has been active in that regard for more than half a year, ranging from the first Starhopper static fire in April to Starhopper’s 150-meter test flight in August. Florida has been almost entirely focused on iterating the build process itself and has already prefabricated nearly two dozen single-weld steel rings that will soon become Starship Mk4.
A step further, SpaceX CEO Elon Musk has made it clear that he is pushing for Starship’s first orbital launch to occur in the first half of 2020, an incredibly ambitious target given that the first Super Heavy booster prototype has yet to begin fabrication or assembly of any kind. Regardless, with that ambitious target in mind, SpaceX still needs to try to build a launch facility capable of standing up to a vehicle more powerful than Saturn V unfathomably quickly.
Head in the clouds
More likely than not, SpaceX’s Pad 39A Starship facilities will (attempt to) be that launch facility. An August 2019 environmental impact statement revealed that SpaceX would avoid Pad 39A’s massive flame trench and instead build a separate water-cooled thrust diverter, a technology SpaceX is extremely familiar with.
The diverter will likely have to be larger than anything SpaceX has ever attempted to build and will take a significant amount of time and money to fabricate, but the approach could potentially allow SpaceX to build Super Heavy-rated launch facilities from scratch in just 6-12 months. Put simply, however, SpaceX is not going to want to build a Starship-sized thrust diverter and launch mount in Florida if it will almost immediately have to build a second, larger replacement big enough for orbital launch attempts with Super Heavy.

All things considered, it’s thus reasonably likely that SpaceX’s first draft of Florida Starship launch facilities will immediately jump to something sized for Super Heavy static fires and launches, even if that means it will take much longer to complete. If the pace of launch pad development in Boca Chica is anything to go by, it’s entirely possible that SpaceX will go from breaking ground at Pad 39A (mid-September 2019) to a more or less complete Starship-Super Heavy launch mount in roughly half a year.
Even if it takes more than a year to build, SpaceX could still be ready to attempt Starship’s first orbital launch well before the end of 2020.

Tesla shows what Roadster drivers will see on screen before thruster activation
Tesla’s Roadster video reveals a fighter jet inspired cockpit with a 5,500 PSI thruster gauge.
Tesla has given future owners their clearest look yet at the cockpit of its next generation Roadster. In a 34 second video posted to X on Friday afternoon, the company walked through the car’s touchscreen with a caption: “Inspired by fighter jet cockpits, Roadster’s interface was designed around the pilot.”
The clip opens on a black screen with red graphics and a 3D wireframe of the car, which sits beside the Roadster’s squared off yoke. Tapping parts of the model brings up controls for the rear wing, including low drag and high downforce positions, along with a charging page with a charge limit bar and a small music player. A row of tabs along the bottom reads Home, Vehicle, Listen, Climate and Navigate.
Most of the video is spent in Track Mode. The dashboard shows a live circuit map, a list of session lap times, brake and motor temperatures, and pressure and temperature readouts for each tire. A setup page lets the driver pick Auto, Low Drag, High Downforce or Custom aero modes, adjust aero balance and brake balance, and switch stability and traction control off. Along the bottom, a status bar reads “Thruster · 5,500 PSI” next to a “Boost Ready” indicator.
That gauge ties the software to the hardware Tesla showed off near Waco, Texas on October 15. The Thrust and Rocket versions use cold gas thrusters fed by carbon overwrapped pressure vessels, and Tesla lists 0 to 60 mph times of under 0.9 seconds and under 0.59 seconds for them, as Teslarati detailed in its breakdown of the three Roadster configurations. The base Performance car relies on a fan and ground sealing system for grip, and the aero settings on screen match the active wings and suction setup covered in our look at how the Roadster generates downforce.
The Roadster layout is a departure from the rest of Tesla’s lineup. Instead of a map centered screen, the Roadster puts the car itself at the center of the home page, and Tesla’s Roadster page lists two smaller forward displays alongside the main touchscreen. Tesla has not said whether any of the Track Mode telemetry will make its way to the Model 3 Performance or other vehicles.
The interface could still change before deliveries. Elon Musk said at the event that Roadster production will begin in 2028, and Tesla says the flagship Rocket version is not approved for public road use. Reservations are open with a $50,000 payment, while Thrust is listed as a limited release and Rocket is invite only.
Those who want to see the car in person will get their first chance this weekend. The Roadster goes on display in the lobby of the Petersen Automotive Museum in Los Angeles from October 24 to 27, according to Sawyer Merritt, the first time the public will be able to view it up close.

Tesla reveals Optimus Academy, where robots teach themselves
Tesla has begun building production quality Optimus robots in Fremont and revealed its training plan.
Tesla has started building Optimus on the high volume line it set up inside its Fremont factory, and the company says the robots coming off it are the first that meet the bar for a real product. “The bots coming off this line are the first production-quality bots that we have manufactured,” Tesla wrote in its third quarter shareholder letter, adding that it has “proven that the current manufacturing process for Optimus is suitable for a commercial product.”
The line sits in space that built the Model S and Model X until this spring. Tesla cleared the old vehicle line in 46 days, as Teslarati reported in July, to make room for robot production sized for one million units a year. On Wednesday’s earnings call, Elon Musk said most of the equipment for that capacity is already in Fremont, with output set to climb toward roughly 20,000 robots a week as the line ramps.
Musk described the ramp as a classic S curve. “The growth of Optimus is an S curve, but the initial curve is a shallow slope,” he said. The team is now refining the robot’s AI, electromechanical design, reliability and service life, and Musk expects that work to be finished by the end of next year, when Tesla plans to start delivering Optimus to outside companies for dangerous, repetitive and around the clock jobs.
The most interesting part of the call was how Tesla plans to teach the robots. Its cars send real driving data back to the AI team from millions of vehicles, but Optimus has no fleet like that yet. “A big difference with Optimus versus the cars is we don’t have this vast fleet of cars from which we can gather training data,” Musk said. Tesla’s answer is an Optimus Academy, where 10,000 to 20,000 robots will practice a wide range of tasks and feed what they learn into the next version of the model. Every unit off the Fremont line becomes a source of that training data.
Smarter hardware is on the way too. Tesla plans to put its AI5 chip into Optimus next year, and Musk said a new Optimus video should arrive within one or two months showing the robot completing tasks driven by AI rather than preprogrammed motions. He took aim at rival humanoid demos that only run scripted routines, saying those would not hold up in the real world.
The supply chain is lining up behind the program. In September, Tesla certified Tuopu, Joyson and Sanhua as mass production partners for Optimus components. A far larger Optimus factory is also rising at Giga Texas, where drone footage from Joe Tegtmeyer showed the steel frame nearing completion, and Musk has pegged that plant’s long term target at 10 million robots a year.
Tesla executives also said Optimus production costs are trending toward the expected manufacturing cost of Cybercab, a sign the robot is being engineered for volume from the start. The hands remain the toughest piece of the design, a point Musk also made at the X Takeover event earlier this month, as Teslarati covered at the time, and that is where much of the current engineering effort is focused.

The Starship moon landing number NASA and Elon Musk can’t agree on
Musk disputes NASA estimate of 22 Starship launches for Moon landing, predicting 6 to 8.
Elon Musk is disputing a new NASA safety panel estimate of how many Starship launches it will take to put astronauts on the Moon, saying the real number will be less than half the panel’s figure.
On Thursday, NASA’s Aerospace Safety Advisory Panel held its quarterly public meeting. Panel member Charlie Precourt, a former NASA astronaut, flagged the fueling process for SpaceX’s lunar lander as a major risk for Artemis IV, the mission planned to land a crew on the Moon in 2028. “We need to keep our eyes on numerous required fuelings for the lander,” Precourt said, according to Ars Technica. “I think the last estimate is around 22 flights.”
Ars Technica’s Eric Berger posted the comment on X, and Musk replied. “That’s way too high,” Musk wrote. “Actual number will be more like 6 to 8.”
The disagreement comes down to a basic problem with sending a ship as large as Starship to the Moon. Starship burns nearly all of its propellant just reaching Earth orbit, so it cannot continue on to the Moon without stopping for a refill. SpaceX’s answer is a gas station in space. First, a Starship that works as a storage tank, called a depot, is launched into orbit. Then a series of tanker Starships launch one at a time, dock with the depot and pump their leftover propellant into it. Once the depot is full, the lunar lander version of Starship launches, docks, fills up and heads for the Moon.
Every tanker trip is its own full rocket launch, which is why the count matters. More launches mean more time, more cost and more chances for something to go wrong before astronauts ever leave Earth. Berger estimated that even if SpaceX reaches twice weekly Starship launches by the end of 2027, filling a depot at the panel’s number would still take roughly three months.
How many tankers are needed depends mostly on how much propellant each one can carry to orbit and how much is lost along the way. Starship’s fuel and oxygen are stored at extremely cold temperatures, and some of it slowly boils off while waiting in orbit. More is lost in each transfer. NASA appears to be working from what Starship can lift today, while Musk’s range assumes a more capable rocket.
Musk has pushed back on higher counts before. In 2021, after a government document suggested 16 launches, he called that “extremely unlikely” and said eight tankers would be the most required.
Much of the answer depends on hardware SpaceX has not finished flying. As Teslarati noted earlier this year, the company plans to carry out the refueling process with its upgraded V3 Starship, and Precourt described Artemis IV as carrying “a large number of firsts.” He also praised NASA Administrator Jared Isaacman’s team for working to clear obstacles for both SpaceX and Blue Origin, whose Blue Moon lander does not rely on orbital refueling for its first mission.
