SpaceX has returned one of its reusable Dragon spacecraft to the Port of Los Angeles for the last time, wrapping up almost a decade of West Coast recovery operations as the company prepares to move East.

Marking the fully successful completion of Cargo Dragon’s CRS-20 space station resupply mission for NASA, the spacecraft’s arrival in port aboard recovery vessel NRC Quest is SpaceX’s 21st since December 2010. CRS-20 was the original Cargo Dragon spacecraft’s very last mission, meaning that the historic vehicle will have effectively entered retirement once SpaceX has finished capsule C112’s post-flight processing. More likely than not, it and its siblings may soon find themselves displayed in SpaceX facilities and aerospace museums across the US, a fitting end for an orbital spacecraft that effectively launched SpaceX onto the world’s spaceflight stage.

Cargo Dragon is by no means the last of its kind, however. SpaceX has already launched Crew Dragon – also known as Dragon 2 – on a flawless March 2019 orbital debut. An uncrewed variant of the same upgraded spacecraft will soon replace Cargo Dragon for uncrewed space station resupply missions under a second NASA Commercial Resupply Services contract (CRS2). For a variety of reasons, SpaceX has decided to move all Dragon 2 recovery operations to its Port Canaveral, Florida hub, now also the sole home of Falcon booster drone ship recoveries and payload fairing catch attempts. This means that April 9th’s Cargo Dragon homecoming is the last time a SpaceX spacecraft will return to the West Coast — a bittersweet end of an era.

Upon its safe return to shore, Cargo Dragon C112 is now the third Dragon spacecraft to successfully complete three separate orbital resupply missions, as well as the ninth Dragon reuse overall. While the recovered spacecraft may look like a very well-toasted marshmallow, all that visible wear and tear comes from a single orbital-velocity reentry, as SpaceX extensively refurbishes each Dragon before they are reused.

Before Cargo Dragon C112 lifted off on a Falcon 9 rocket for the third time on March 7th, it looked about as pristine as it did the first time it departed SpaceX’s Hawthorne, California factory in 2016. Aside from a duo of International Space Station badges added to the spacecraft’s exterior, it is functionally and visually identical, although parts of the capsule – like landing parachutes and its ablative heat shield – must be replaced after each mission.

Still, despite having to clean and resurface the spacecraft’s white thermal protection, replace heat shields, fabricate new disposable trunk sections, and much more for every launch, SpaceX CEO Elon Musk has stated that even the first Dragon reuse (likely the most expensive) was at least 50% cheaper than building a new spacecraft. Additionally, SpaceX clearly began to find its stride on Dragon capsule C112’s CRS-20 refurbishment, completing the process with record-breaking speed.

As previously discussed on Teslarati, “measured from splashdown to the capsule’s shipment to the launch pad, SpaceX may have spent less than a year refurbishing Cargo Dragon C112, potentially more than a 50% faster than all prior Dragon refurbishment operations.” Cargo Dragon’s Dragon 2 replacement is expected to be far easier to refurbish, while also potentially allowing for up to five orbital missions per spacecraft, while Dragon 1’s design was capped at three missions.

CRS-21 – SpaceX’s first NASA CRS2 mission and the first planned Cargo Dragon 2 launch – is scheduled for no earlier than (NET) October 2020. Meanwhile, Crew Dragon’s “Demo-2” astronaut debut is set to launch as early as late May. If successful, NASA says Crew Dragon’s first operational astronaut launch could happen as early as a month or two after splashdown (~Q4 2020).

After completing their orbital duties, all of those upgraded Dragon spacecraft are scheduled to reenter and splash down in the Atlantic Ocean, where they will be brought back to Cape Canaveral for processing and refurbishment. In the event that weather in the Atlantic Ocean is unacceptable for recovery operations, SpaceX has developed a backup recovery zone in the Gulf of Mexico. In short, it’s possible that Cargo Dragon’s April 7th Port of Los Angeles return will be the last time ever that the US West Coast supports orbital spacecraft recovery operations.

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.
