SpaceX sends Falcon 9’s West Coast drone ship to the Panama Canal in surprise move
In a surprise turn of events, SpaceX has decided to send Just Read The Instructions (JRTI) – one of the company’s two autonomous spaceport drone ships (ASDS) – from Port of Los Angeles to either the Gulf or East Coast.
The likely destination: either Port Canaveral, Florida or Port of Brownsville, Texas. This move comes as the company enters a major lull in launch activities from its West Coast SLC-4 pad, situated in California’s Vandenberg Air Force Base (VAFB). Lacking manifested launches, SpaceX has gone as far as redistributing almost all of its VAFB-based launch team and laying off those that could not move to Texas or Florida. As early as the first half of 2020, this major move east could easily culminate in the end of all West Coast SpaceX fleet activity, aside from a rare fairing retrieval or two.
On June 12th, SpaceX successfully launched what is expected to be its last West Coast mission for at least 6-9 months, while drone ship JRTI was most recently used to recover a VAFB-launched Falcon 9 booster during the January 11th launch of Iridium NEXT-8. Unexpectedly, it appears that Falcon 9 B1049.2’s landing aboard JRTI will be the drone ship’s last West Coast recovery for quite some time.

On August 1st, the approximately 300 foot by 170 foot converted barge departed its well-worn Port of Los Angeles berth behind tugboat “Alice C”. In fact, the drone ship’s departure went unknown for a solid 12-24 hours before a member of the unofficial SpaceX subreddit (/r/SpaceX) discovered paperwork filed with the Panama Canal Authority for an August 15th passage.
Back in January 2019, SpaceX fairing recovery vessel Mr. Steven (now GO Ms. Tree) – in a bit of what now is obvious foreshadowing – began a very similar ~5000 mi (8000 km) journey, traveling from Port of LA to Port Canaveral via the Panama Canal. Mr. Steven, however, is a far faster ship and sustained a solid 15-20 knots (17-22 mph) over the entire voyage, while drone ship JRTI – towed the entire way – will have to suffice with an average speed less than half that.
Where to?
Assuming a day-long canal passage, JRTI’s journey to Port Canaveral or Brownsville would take no less than three weeks (~22 days) from start to finish, indicating a likely arrival at the unknown final destination in the third week of August. The two probable destinations, Texas and Florida, would both arguably make sense.
In Florida, SpaceX drone ship Of Course I Still Love You (OCISLY) is now tasked with handling the vast majority of SpaceX’s non-LZ booster recoveries, including Falcon Heavy center cores. In February 2018, CEO Elon Musk noted that a third drone ship (aside from JRTI & OCISLY) was “under construction” with the intention of allowing SpaceX to conduct Falcon Heavy launches where the center core is expended and both side boosters land at sea.
Perhaps SpaceX analyzed its fairly short West Coast manifest and decided that it would be even faster (and cheaper) to simply send JRTI East. Falcon Heavy’s next (public) launch is scheduled no earlier than late 2020, ruling out that as a primary motivation, but SpaceX is also about to begin operational Starlink launches that will demand an unprecedented cadence. Starlink’s cadence requirements could be so high that a second dedicated drone ship is necessary to prevent SpaceX’s internal manifest from delaying and generally disrupting its customers’ launches, thus explaining JRTI’s move.

At the same time, the spectacular pace of SpaceX’s orbital Starship prototype construction could very well demand the use of a large ocean-based landing platform in the near-term, at least according to Elon Musk’s recent comments on the subject of the first Starship test flights. Per Musk, either or both of SpaceX’s two Starship Mk1 (technically Mk1 & Mk2) prototypes could be ready for their first significant flights as early as September 2019, initially targeting altitudes of at least 20 km (12 mi).

Somewhat coincidentally, Starship’s tripod fin-legs – circa. a September 2018 design update – would actually almost fit inside the span of a Falcon 9 booster’s deployed landing legs (~18m diameter). This is to say that SpaceX’s two drone ships may already be large enough (give or take) to support Starship and Super Heavy booster landings. Given that the SpaceX plans to eventually put one or both of the in-work orbital Starship prototypes through an increasingly intensive series of high-speed, high-altitude (but still suborbital) tests before the first orbital flights, a drone ship may be necessary for the same reasons that not all Falcon 9 boosters can conveniently return to land during recovery.
Regardless of the ultimate purpose of drone ship JRTI’s move, it is undoubtedly a sign that things are about to get even more interesting and exciting in the world of SpaceX.

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.
