SpaceX and NASA accidentally set the stage for a new race to the Moon
Almost entirely driven by chance, SpaceX and NASA may soon find themselves in an unintentional race to return humans to the Moon for the first time in half a century.
Both entities – SpaceX with its next-generation BFR and NASA with its Shuttle-derived SLS – are tentatively targeting 2023 for their similar circumlunar voyages, in which NASA astronauts and private individuals could theoretically travel around the Moon within just months of each other, showcasing two utterly dissimilar approaches to space exploration.
Over the course of no fewer than seven years of development, NASA’s SLS rocket and Orion spacecraft have run into an unrelenting barrage of issues, effectively delaying the system’s launch debut at a rate equivalent to or even faster than the passage of time itself. In other words, every month recently spent working on the vehicle seems to have reliably corresponded with at least an additional month of delays for the launch system.
Why these incessant delays continue to occur is an entire story in itself and demands the acknowledgment of some uncomfortable and inconvenient realities about the state of NASA’s human spaceflight program in the 21st century, but that is a story is for another time.

A different kind of paper rocket
Returning to SLS, a brief overview is in order to properly contextualize what exactly the rocket and spacecraft are and what exactly their development has cost up to now. SLS is comprised of four major hardware segments.
- The Core Stage: A massive liquid hydrogen/liquid oxygen rocket booster, this section is essentially a lengthened version of the retired Space Shuttle’s familiar orange propellant tank, while the stage’s four engines are quite literally taken from stores of mothballed Space Shuttle hardware and will be ingloriously expended after each launch (SLS is 100% expendable).
- Solid Rocket Boosters (SRBs): Minimally modified copies of the SRBs used during the Space Shuttle program, SLS’ SRBs have slightly more solid propellant and have had all hints of reusability removed, whereas Space Shuttle boosters deployed parachutes and were reused after landing in the Atlantic Ocean.
- The Upper Stage (Interim Cryogenic Propulsion System, ICPS): ICPS is a slightly modified version of ULA’s off-the-shelf Delta IV upper stage.
- The Orion spacecraft and European Service Module: Borrowing heavily from the Apollo Command and Service Modules that took humanity to the Moon in the 1960s and 70s, Orion has been in funded development in one form or another for more than 12 years, with just one partial flight-test to call its own. Orion’s development has cost the U.S. approximately $16 billion since 2006, with another $4-6 billion expected between now and 2023, a sum that doesn’t account for the costs of production and operations once development is complete.

For the SLS core stage and SRBs, a generous bottom-rung estimate indicates that $14 billion has been spent on the rocket itself between 2011 and 2018, not including many billions more spent refurbishing and modifying the rocket’s aging Saturn and Shuttle-derived launch infrastructure at Kennedy Space Center. Of the many distressing patterns that appear in the above descriptions of SLS hardware, most notable is a near-obsessive dependence upon “heritage” hardware that has already been designed and tested – in some cases even manufactured.
Despite cobbling together or reusing as many mature components, facilities, and workforces as possible and relying on slightly-modified commercial hardware at every turn, SLS and Orion will somehow end up costing the United States more than $30 billion dollars before it has completed a single full launch; potentially rising beyond $40 billion by the time the system is ready to launch NASA astronauts.
Moonward bound
SLS’ first crewed mission, known as Exploratory Mission-2 (EM-2), brings us to the title – NASA’s mission planning has settled on sending a crew of four astronauts on what is known as a Free Lunar Return trajectory in the Orion spacecraft, essentially a single flyby of the Moon. Official NASA statements appear to be sending mixed messages on the schedule for EM-2’s launch, with September 2018 presentations indicating 2022 while a late-August blog post suggests that the crewed circumlunar mission is targeting launch in 2023.
As it happens, SpaceX announced its own plans for a (private) crewed circumlunar voyage less than two weeks ago. Funded in large part by Japanese billionaire Yasuka Maezawa, SpaceX’s hopes to send 10+ people to the Moon on its next-generation BFR launch vehicle, comprised of a fully-reusable booster and spaceship. Deemed Dear Moon by Maezawa, SpaceX is targeting an extremely ambitious launch deadline sometime in 2023, although CEO Elon Musk frankly noted that hitting that 2023 window would require all aspects of BFR booster and spaceship development to proceed flawlessly over the next several years.
Compared to the 10+ years and $30+ billion of development SLS and Orion will have taken before their first full launch, SpaceX is targeting the first orbital BFR test flights as early as 2020 or 2021, self-admittedly optimistic deadlines that will likely slip. Still, betting against SpaceX completing its first BFR launch sometime in the early to mid-2020s for something approximating Musk’s $2-10 billion development cost seems a risky move in the context of SpaceX’s undeniable track record of proving the old-guard wrong.

It must be noted that the apparent alignment of both SpaceX and NASA’s first crewed circumlunar missions with new rockets and spacecraft is a fluke of chance, and the fact that it may or may not take the shape of a second race to the Moon – pitting two dramatically different ideologies and organizational approaches against each other – is purely coincidental.
However, despite the undeniable fact that NASA and SpaceX are deeply and cooperatively involved through Crew and Cargo Dragon and despite Musk’s genuine affirmations of support and admiration for the space agency, it can be almost guaranteed that the world will look on in the 2020s with the same underlying emotions and motivations that were globally present during the Apollo Program. Rather than a battle of economic and nationalistic ideologies, the New Space Race of the 2020s will pit two (publicly) amicable private and public entities against each other at the same time as they work hand-in-hand to deliver crew and cargo to the International Space Station.

Critically, this new “race” will be fairly illusory. Thanks to the fact that the new goal of human spaceflight appears to be the sustainable exploration of the solar system, there will inherently be no Apollo-style finish line for any one company or country or agency to cross. Rather than the Apollo Program’s shortsighted economic motivations and its consequentially abrupt demise, the end-result of this new age of competition will be the establishment of humanity as a (deep) spacefaring species, be it a temporary burst of effort or a permanent human condition.

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.
