NASA head hints that reusable rocket cos. like SpaceX will enable Moon return
In a series of thoroughly unexpected and impassioned introductory remarks at one of several 2018 Advisory Council meetings, NASA administrator Jim Bridenstine bucked at least two decades of norms by all but explicitly stating that reusable rockets built by innovative private companies like SpaceX and Blue Origin will enable the true future of space exploration.
Incredibly, over the course his fascinating hour-long prelude, Bridenstine effectively mentioned NASA’s own SLS rocket and Orion spacecraft – under development for the last decade at a cost of at least several tens of billions of dollars – a total of one time each. Instead, heavily emphasizing the absolute necessity that NASA’s next major human exploration project be sustainable, the administrator spoke at length about the foundational roles that international and domestic space agencies and private companies will need to take on in order to make NASA’s on-paper return to the Moon both real, successful, and useful.
Aside from his arguably brave (but spot-on) decision to all but ignore Boeing and Northrop Grumman’s SLS rocket and Lockheed Martin’s Orion spacecraft over the course of an hour spent speaking about the future of NASA’s human exploration of the Moon and on spaceflight more generally, Bridenstine had nothing but praise for recent successes in the American aerospace industry.
Most notably, he spoke about his belief – at least partially stemming from an executive order requiring it – that the only way NASA can seriously succeed and continue to lead the world in the task of human space exploration is to put an extreme focus on sustainability. Judging from his comments on the matter, the new NASA/Federal buzzword of choice is just a different way to describe hardware reusability, although it certainly leaves wiggle room for more than simply avoiding expendable rocket hardware.
“It’s on me to figure out how to [return to the Moon] sustainably. … And this time, when we go, we’re gonna go to stay. So how do we do go sustainably? Well, [we take] advantage of capabilities that didn’t exist in this country even five or ten years ago. We have commercial companies that can do things that weren’t possible even just a few years ago … to help develop this sustainable [Moon exploration] architecture.” – NASA Administrator Jim Bridenstine, 08/29/2018
While it might not look like much (aside from a “no duh” statement) to anyone unfamiliar with the trials and tribulations of NASA bureaucracy and politicking, this quote – directed at an audience of senior NASA scientists and managers and independent experts – is absolutely extraordinary in the context of NASA’s history and the formulaic eggshells NASA administrators have traditionally been forced to walk on when discussing American rocketry.
Not only is SLS/Orion utterly and conspicuously absent in a response to the “how” of starting a new wave of lunar exploration, but Bridenstine also almost explicitly names Blue Origin and SpaceX as torchbearers of the sort of exceptional technological innovation that might revolutionize humanity’s relationship with space. By referring specifically to “commercial companies that can do things that weren’t possible even just a few years ago”, the only obvious answers in the context of serious human exploration on and around the Moon are Blue Origin and SpaceX, both of which managed their first commercial rocket landings in late 2015.
Bridenstine went even further still, noting that NASA will need not just reusable rockets for this sustainable lunar exploration, but also reusable orbital tugboats (space tugs) to sustainably ferry both humans and cargo to and from Earth and the Moon and reusable lunar landers capable of many trips back and forth from space stations orbiting the moon. At one point, he even used SpaceX CEO Elon Musk’s (in)famous and well-worn analogy of commercial airlines to emphasize the insanity of not using reusable rockets:
“We have reusable rockets [now]… Imagine if you flew here across the country to [NASA Ames] in a 737 and when the mission was over, you threw the airplane away. How many of you would have flown here?” – NASA Administrator Jim Bridenstine, 08/29/2018
At today's NASA Advisory Council (NAC) meeting, Administrator Jim Bridenstine says the next hop to the moon is going to be sustainable – and will require reusable spaceflight hardware. Uses the same airplane analogy @ElonMusk does when it comes to explaining advantages.

Reusable rockets lead the charge
It may be generous to include Blue Origin side by side with SpaceX, given the fact that its New Shepard rocket is extremely small and very suborbital, but the company does have eyes specifically set lunar landers and outposts (a project called Blue Moon) and is developing a large and reusable orbital-class rocket (New Glenn) set to debut in the early 2020s.

- Blue Origin’s aspirational future, the highly reusable BE-4 powered New Glenn rocket. (Blue Origin)

- Blue Origin’s Blue Moon concept, set to begin experimental lunar landings as early as 2022 or 2023. (Blue Origin)
SpaceX, while focused on Mars colonization, has also expressed a willingness to participate in any sort of lunar exploration that NASA or other international space agencies might have interest in. Currently in the middle of developing its own massive and fully reusable rocket, known as the Big F_____ Rocket (BFR), SpaceX nevertheless already has a flight-tested, highly successfully, and unbeatably cost-effective family of reusable Falcon rockets capable of affordably launching significant mass to the Moon. In fact, both NASA and ESA (European Space Agency) are already seriously considering SpaceX’s Falcon Heavy as the launch vehicle of choice for several critical pieces of a Moon-orbiting space station, expected to launch no earlier than the early to mid-2020s.
Whether or not Bridenstine’s incredible and eloquent statements translate into tangible changes to NASA’s long-term strategy, it’s quite simply refreshing to hear a senior NASA executive – let alone the administrator – speak freely and rationally about the reality of what is needed to enable a truly new era of human spaceflight and exploration.

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.
