Welcome to the latest edition of DeepSpace! Each week, Teslarati space reporter Eric Ralph hand-crafts this newsletter to give you a breakdown of what’s happening in the space industry and what you need to know.

In this week’s analysis, there is simply too much going on to focus on any single overarching theme. NASA awarded ~$250M to fund three commercial Moon landers, Russia revealed an impossibly ambitious schedule for its conceptual crewed Moon program, and NASA’s Office of the Inspector General (OIG) released a report that did not look kindly on the management of the Europa Clipper spacecraft’s supposed plans for an SLS rocket launch.

While it is increasingly clear that the 2020s are likely to be the most exciting period of spaceflight activity in decades, it remains equally clear that most of the world’s space exploration – despite the incredible results often produced – is poorly and inefficiently managed. Upsets may well be served by commercial hopefuls like SpaceX, Blue Origin, iSpace, and others, but we are likely set to witness another decade or so of wasteful, results-phobic human spaceflight efforts lead on a wild goose chase after NASA’s Moon return ambitions. If it ends up being anything like the SLS rocket and Orion spacecraft it is being artificially locked to, the Moon return may eventually accomplish something approximately half a decade behind schedule after vacuuming up at least $10-20B of federal funding.

At the same time, the robotic exploration expertise of NASA, ESA, Japan (JAXA), China (CNSA), India (ISRO), and Russia (Roscosmos) will be thrown at a bevy of spacecraft and landers with destinations throughout the solar system.

Europa Clipper deserves better ‘sails’

  • As of now, Congress has “mandated” that Europa Clipper and a planned Lander follow-up both launch on NASA’s Space Launch System (SLS) rockets. This was a political ploy by long-time supporter John Culberson (now a former US representative) meant to gain the support of Congressional gatekeepers focused on preserving SLS and Orion-related pork that feeds into their legislative districts or states (Sen. Shelby, Sen. Nelson, and others).
  • Developed by Lockheed Martin with the support of the European Space Agency (ESA), the Orion spacecraft is essentially an overweight, underpowered modern version of NASA’s Apollo Command and Service Module (CSM). Despite its mediocre capabilities, the spacecraft could theoretically be useful for NASA’s crewed exploration ambitions.
    • Sadly, Orion has been almost inextricably linked to NASA’s SLS rocket, built (for the most part) by Boeing and Aerojet Rocketdyne. Originally known as Ares V, the comparatively downsized SLS has always been meant to launch extremely large payloads. In theory, even the early SLS Block 1 (likely the only variant that will ever fly) would be capable of delivering ~25 metric tons to Mars and 6.3 mT directly to Jupiter.
  • That performance would also drastically cut the amount of time it takes Europa Clipper to travel from Earth to Jupiter from 6-7 years to about 3 years.
  • Hilariously, despite both Europa Clipper and SLS having been in development for years and the latter being legally required to launch the former, NASA still hasn’t verified (with certainty) that SLS Block 1 is actually capable of launching EC directly to Jupiter, the only benefit of SLS being the 3 years of time saved by a direct trajectory.
  • Even worse, despite mission delays that pushed Europa Clipper’s launch target from 2022 to 2023, NASA has yet to actually order new SLS boosters beyond the first two, assigned to Orion missions NET 2021 and 2022.
    • As NASA OIG notes, according to past estimates from NASA officials, the agency would need a minimum of 52 months (4.3 years) of lead time for Boeing and Aerojet Rocketdyne to build new SLS boosters. In other words, NASA would have had to order new boosters in September 2018 (8 months ago) for Europa Clipper to have a chance of launching on SLS in 2023.
  • Due to all of this absurd and avoidable uncertainty, large amounts of money and time are being wasted designing Europa Clipper to essentially be launcher-agnostic, able to fly on Falcon Heavy, Delta IV Heavy, or SLS. At this rate, it’s not even clear if a third SLS will be ready to launch Europa Clipper in 2024, barring a miraculously perfect performance during its launch debut (“Artemis-1”, formerly EM-1).

Dispatch from the Moon (bureaucracy)

  • Earlier this week, NASA announced its first truly Moon landing-focused contracts, awarding a total of $253M to OrbitBeyond, Astrobotic, and Intuitive Machines for commercially-developed Moon landers that could be ready for lunar landings as early as September 2020, July 2021, and July 2021, respectively.
    • Astrobotic and Intuitive Machines aim to deliver 90 kg and 100 kg of payload to the Moon’s surface, while OrbitBeyond is targeting ~40 kg despite receiving ~$25M more from NASA. Regardless, it has to be said that ~$250M is extremely cost-effective for the 230 kg (510 lb) worth of payloads it could deliver to the Moon. For comparison, in 2015, NASA purchased a single Delta IV Heavy launch (for its Parker Solar Probe) at a cost of almost $390M
    • Not only does that $250M include launch costs (two or even three of which will likely end up as copassengers on Falcon 9 launches), but it includes delivery to the surface of the Moon.
  • Additionally, an unknown proportion of that funding has clearly been directed towards the development and maturation of unflown and (mostly) unbuilt lunar landers, all of which could potentially offer even more affordable lunar delivery services once development is finished.
  • Finally, Russian space agency Roscosmos apparently has plans (or at least a Powerpoint) to land cosmonauts on the Moon as early as 2030. To accomplish that incredibly ambitious feat, Russia would effectively need to develop three entirely new rockets – two of which are far larger than anything Russia has built since the fall of the USSR – and a brand new crew and deep space-capable spacecraft (Federation).
  • The ambition is undeniably inspiring and could create a truly fascinating race-that-isn’t-really-a-race back to the Moon. However, the reality is that Russia as a country and economy is struggling, and those difficulties are obvious in Roscosmos – woefully underfunded and eternally tossed about as a political puck and source of easy embezzlement.
    • A Soyuz spacecraft launched to the ISS last year was found to have a literal hole in it, the likely result of sloppy manufacturing and nonexistent quality control. A few months later, a Soyuz 1.2 rocket failed mid-flight while launching a trio of astronauts, triggering the first human spaceflight abort/failure in almost two decades.
    • All three astronauts were safely recovered but those two failures alone suggest that Russia has some soul-searching a budget-tweaking to do before it has any chance of successfully (let alone safely) undertaking its ambitious lunar program.

Eric Ralph is Teslarati's senior spaceflight reporter and has been covering the industry in some capacity for almost half a decade, largely spurred in 2016 by a trip to Mexico to watch Elon Musk reveal SpaceX's plans for Mars in person. Aside from spreading interest and excitement about spaceflight far and wide, his primary goal is to cover humanity's ongoing efforts to expand beyond Earth to the Moon, Mars, and elsewhere.

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.
