Speaking on September 28th, SpaceX CEO Elon Musk sketched out a fairly detailed picture of Starship’s path to orbit, from the first flight of the first full-scale prototype to the spacecraft’s inaugural orbital launch atop a Super Heavy booster.

Incredibly, Musk was persistent with claims that he has challenged SpaceX’s Starship teams to conduct the next-generation rocket’s first orbital launch within six months, drawing a line in the sand around April 1st, 2020 (?). How, then, does the SpaceX CEO foresee the next year or so playing out?

A whole lotta ‘Ships

As is the company’s signature, Musk confirmed that the Starship development program will continue to be highly distributed, hardware-rich, and focused on an iterative and continuous process of learning by doing. Starhopper is perhaps the best emblem of this methodology, defying almost every conceivable aerospace industry norm to successfully build and repeatedly fly what was essentially a rocket built outside by water tower welders.

Starhopper may have scarcely been meant to fly at all, serving almost entirely as a proof of concept and learning experience, but Musk strongly suggested that future Starship prototypes will replicate its highly iterative, learning-on-the-job approach to development. In short, much like SpaceX has nearly completed Starship Mk1 (and Mk2) from scratch in less than six months, SpaceX’s development strategy involves building a lot of Starship prototypes as quickly as possible.

Specifically, Elon Musk stated – in his opinion – that SpaceX will likely attempt its first orbital Starship-Super Heavy launch immediately after Starship Mk1’s first flight attempt, a suborbital launch to ~20 km (12.5 mi). Assuming that test – far more critical than any of Starhopper’s travails – is successful, the very next Starship flight could be an orbital launch attempt.

First and foremost, Musk was pretty clear that the rough schedule he laid out was a “stream of consciousness”. Indeed, the eccentric CEO contradicted (or updated) himself over the course of answering the same question, stating that “[SpaceX] would fly to orbit with [Starship] Mk3” before saying that that it would actually be “Mk4 or Mk5”. Musk is still undoubtedly set on announcing gobsmackingly ambitious schedules for his projects, but it’s worth noting just how serious he seemed while discussing Starship’s development timeline.

He noted that SpaceX will likely “have [Starship] Mk2 built within a couple of months – or less”, referring to the second prototype currently in the late stages of integration at the company’s similar Cocoa, FL facilities. Additionally, Musk indicated that Starship Mk3 – yet to begin construction in Boca Chica – could be finished as few three months from now (around the start of 2020), with Starship Mk4 – to be built in Florida – could be just one to two months behind (NET Feb/March 2020). Correcting his previous statement, whether intentional or not, Musk also added that SpaceX’s first orbital Starship launch attempt would likely involve either the Mk4 or Mk5 prototype and occur “less than six months from now”.

As a slight consolation to the eyewateringly ambitious timeline he laid out, Musk qualified his “six months to orbit” target by acknowledging that it would only be achievable “provided the rate of design and manufacturing improvement continues to be exponential”. If that remains the case, as he believes it has been over the last six or so months, then SpaceX could be ready for the first orbital Starship launch attempt as few as 6-9 months from now – sometime in the first half of 2020.

A lot will undoubtedly have to go very right for that to remain anywhere within the realm of plausibility. This includes the rapid maturation of Starship’s Raptor engine and vacuum-optimized variant, the successful completion of Starship Mk1’s 20km flight test, the assembly and static fire of the first Super Heavy booster(s), the construction of brand new orbital launch facilities, and the FAA’s approval of all aforementioned flight operations.

Needless to say, the odds are heavily stacked against Musk’s goal of reaching orbit within six months. There is undoubtedly a chance that SpaceX can pull it off, even if success would essentially involve constructing a bridge while driving off a cliff. However, the most important thing to note is that even if Elon Musk is a factor of 1.5, 2, 3, or even 4 times off and Starship reaches orbit for the first time 12 or 18 or 24 months from now, it will still have been an incredibly brisk period of development for a rocket as large, high-performance, and ambitious as Starship/Super Heavy.

It should also be made clear that, while it’s utterly beyond the present capabilities of NASA and other space agencies/companies of the 21st century, Saturn V went from paper to its first orbital launch in just five years. Depending on how one perceives Starship development, it could be said that SpaceX began development – particularly marked by Raptor engine prototype testing – as early as 2016. Suffice it to say that it’s far from impossible that Starship’s first orbital launch will happen next year, even if the challenges SpaceX faces are immense.

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

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.
