SpaceX has no plans to reuse Crew Dragon spaceships on NASA astronaut launches
According to program manager Kathy Lueders, SpaceX has chosen against reusing its upgraded Crew Dragon spaceships on NASA Commerical Crew Program (CCP) launches, even though NASA itself explicitly provided both CCP providers (Boeing and SpaceX) the option to propose reflights of crew capsules.
In fact, Boeing did just that with their CST-100 Starliner spacecraft, proposing to land Starliners on land (using airbags) and reuse the capsules repeatedly, up to 10 times each. While there is next to no official information on the matter, the question of what SpaceX is planning to do with its flight-proven Crew Dragon spacecraft is well worth puzzling over.

The future of flight-proven Dragon 2s
Speaking at the most recent (August 27) NASA Advisory Council meeting, Lueders specifically stated that SpaceX had proposed “a new vehicle every time for [NASA]”, although NASA specifically provided the option for either new or reflown hardware, similar to Commercial Cargo where SpaceX already routinely reflies both Falcon 9s and Cargo Dragons on official NASA resupply missions.
The fact that SpaceX already routinely reuses Cargo Dragons – and even does so atop flight-proven Falcon 9 rocket boosters – adds additional intrigue to this seemingly odd decision. However, in the context of other near-term plans for other Dragon-related activities, SpaceX’s choice to not (at least in the near-term) refly Crew Dragon capsules for crewed NASA launches makes more than a little sense.

The single most obvious explanation can be found in SpaceX’s next Commercial Resupply Services contract (CRS-2), a similar follow-up to the CRS-1 contract SpaceX is currently launching Cargo Dragons under. Although SpaceX offered its Dragon 1 (already flying) as an option, NASA sided with Dragon 2 thanks to a number of unique and valuable capabilities offered by the upgraded craft. While no official detail has been released by NASA on the gritty specifics of those CRS-2 contracts, an April 2018 report from the Office of the Inspector General (OIG) offers a bit more insight into SpaceX’s plans.
Although the OIG report in question never specifically states it, some of the language used to describe Dragon 2’s cargo configuration does seem to imply that Cargo Dragon 2s will predominately (if not exclusively) be derived as slightly-modified Crew Dragon capsules, seemingly indicating that SpaceX’s CRS-2 missions may only ever launch flight-proven Crew Dragon capsules. Depending on the extent of the disassembly required to remove the components described below, all other “modifications” are essentially one-and-done after the software and additional designs are completed. As such, it should be relatively straightforward to modify the vehicles between Crew and Cargo configurations.

This strategy would make a lot of sense: by using its Commercial Crew contract as a means to fund the construction of brand new Crew Dragon capsules and Falcon 9 rockets and then using those once flight-proven rockets and spacecraft for other NASA cargo launches, general commercial missions, and maybe even low Earth orbit tourism, SpaceX can likely extract as much value and utility as possible from that hardware.
Despite the fact that NASA in this situation would effectively be carrying a significant portion of SpaceX’s non-BFR production-related capital expenditure, the company’s CRS-2 and Commercial Crew contracts place its cargo and crew launch costs far below those of competitors Boeing, Orbital ATK (now Northrop Grumman Innovation Systems), and Sierra Nevada. Overall, SpaceX’s launch costs to NASA range anywhere from 40-75% less than its three competitors’ best offerings, essentially invalidating any nitpicking over slight cost increases from CRS-1 to CRS-2.
Even if SpaceX never ends up reusing Crew Dragons on crewed NASA launches, NASA is still likely to benefit from lower costs derived by the partial modification and reuse of those same capsules and Falcon 9 boosters on CRS-2 cargo resupply missions.

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.
