SpaceX to shift Falcon 9’s next West Coast launch to Florida, the first of its kind in decades
According to NASASpaceflight spaceflight reporter Michael Baylor and an Argentinian government website, SpaceX appears to have decided to move its next West Coast launch from California to Florida, signifying the first East Coast polar launch in half a century could be just four months away.
Initially expected to launch out of SpaceX’s Vandenberg Air Force Base (VAFB) SLC-4E pad on a Falcon 9 rocket, the Argentinian space agency’s (CONAE) SAOCOM-1B Earth observation satellite was scheduled to lift off no earlier than February 2020. That launch window remains the same but Florida’s Cape Canaveral Air Force Station (CCAFS) has somehow arranged approval to reopen the United States’ Eastern polar launch corridor. The story behind the corridor’s closure is a bizarre one.
Having earned itself a bit of notoriety and fame over the years, the story of the closure of the Eastern polar launch corridor is simple on the outset. In November 1960, a Thor Able-Star rocket lifted off from Cape Canaveral for what was hoped to be a routine military launch. This particular mission carried GRAB II, a covert signals intelligence spacecraft designed to spy on radio communications around the globe.
Long story short: that Thor rocket suffered a failure that caused the booster to prematurely shut down and divert from its planned trajectory, forcing the range safety officer to manually trigger the rocket’s self-destruct mechanisms. Broken apart by explosives, one unlucky cow – standing in a Cuban field some 400 miles (650 km) downrange – was struck by rocket debris, killing the farm animal. Indeed, this might initially seem like an absurd reason to entirely end the practice of polar orbital launches from Cape Canaveral, but Cold War tensions were extremely high and President Fidel Castro leaped on the opportunity to hound the US.

An article published in a 2008 issue of the US Naval History Magazine covers this minor debacle in greater detail, shedding some much-needed light on why things played out how they did.
“In what somewhat inaccurately became known as “the herd shot around the world,” some of the falling rocket debris apparently splattered on a Cuban farm and killed a cow. “This is a Yankee provocation,” accused Revolucion, an official Cuban publication, insisting that the rocket was deliberately exploded over the country. Government radio stations cited the incident as further proof that the United States was trying to destroy the regime of Cuban President Fidel Castro. One cow was even paraded in front of the U.S. Embassy in Havana wearing a placard reading “Eisenhower, you murdered one of my sisters.”
Castro filed a complaint at the United Nations, and Washington sheepishly conceded the possibility that “fragments from the rocket booster” could have landed in Cuba. CIA Director George Tenet later quipped somewhat tastelessly that it was “the first, and last, time that a satellite had been used in the production of ground beef.” Further launches overflying Cuba were postponed, and improvements were made to the Cape Canaveral range-safety system. In any case, it was a dejected NRL group that returned to Washington.”
Naval History Magazine – April 2008
That overflight postponement was never withdrawn and VAFB – located on the coast of California – has supported all US polar launch** activity since late-1960. Public word of the possible reopening of the Eastern polar launch corridor came 57 years later when Wayne Monteith, commander of the 45th Space Wing, revealed that he had tasked analysts to determine whether the corridor could be reopened in light of wildfire troubles that closed VAFB’s Western Range in 2016. They concluded that there were no obvious technical showstoppers.
**There is a report that a Thor Delta C rocket performed two sun synchronous orbit (SSO; ‘nearly polar’) launches in the mid-1960s, overflying Cuba in the process, but it’s unclear if the trajectory used was the same as those used before Thor’s 1960 GRAB II failure.
A reporter who was present at the press conference said that SpaceX’s SAOCOM 1B launch hadn’t officially been put on on the Eastern Range’s planning schedule, indicating that some work remains before it can truly be said that the Eastern polar launch corridor has been reopened. Nevertheless, Douglas Schiess, the current commander of the 45th Space Wing, was obviously confident that those final steps are more technicalities than potential showstoppers and that 21st-century Eastern polar launches are now a question of “when”, not “if”.
In Monteith’s 2017 statement, it was stated that there is one major condition on the reopening: all launch vehicles intending to fly it must feature autonomous flight termination systems (AFTS). This is due to the risk that the rocket’s plume might prevent the reliable reception of radio telemetry at Florida-based tracking stations. SpaceX is currently the only launch provider in the world to have implemented AFTS and is thus the only provider currently capable of launching polar missions from Florida.

Time will tell just how extensive Florida’s polar launch capabilities are and how dramatically the new capability will impact Vandenberg’s commercial launch ecosystem. Speaking in 2017, Monteith was fairly blunt in his assessment that California was not only tepid on the subject of expanding VAFB’s commercial launch manifest, but was actively hostile at points. His point: if Vandenberg isn’t going to put effort into stimulating a commercial polar launch ecosystem, Cape Canaveral might as well try.
VAFB is currently in the throes of a four-month launch lull previously expected to last until SpaceX’s Feb. 2020 SAOCOM 1B launch. Depending on how things play out for startup Firefly Aerospace and how readily CCAFS can take to its new polar launch role, Vandenberg’s lull could easily stretch into the second half of 2020, perhaps more than a year between launches.

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.
