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.
- Falcon Heavy’s side boosters seconds away from near-simultaneous landings at Landing Zones 1 and 2. (SpaceX)
- We’re not here just yet, but SpaceX is pushing hard to build BFR and get humanity to Mars as quickly as practicable. (SpaceX)
- 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 Cybercab and Robotaxi’s real advantage won’t be the ride service
For a century, the car has asked the same thing of its owner, which is basically to pay attention. Even the best ride-hailing app like Uber or Lyft only moved the problem into someone else’s hands. You stopped driving, but you still sat in a stranger’s car, while half listening, and wondering whether to take a phone call in the car without being rude. The Cybercab has no wheel, no pedals and no driver. With Grok @bot now live inside it, it becomes something else entirely, and I think that matters more than the fleet count that everyone is tracking.
Grok @bot is an agent, not a voice assistant. A rider signs in once, and from then on can say what they need and watch it happen. Order dinner from a favorite restaurant. Fill the grocery cart. Move money, answer email, adjust a calendar, push a work project forward. Tesla engineer Yun-Ta Tsai confirmed it is enabled across every Cybercab and the rest of the Model Y fleet, and Tesla’s own pitch is that Full Self-Driving handles the commute while Grok handles the errands.
Think about what that does to a thirty minute ride. Uber sells you a trip, while Waymo sells you the same trip in a more private setting. Tesla is selling the thirty minutes themselves, returned to you with an assistant attached. Errands that used to eat a Saturday get done between pickup and drop off. The ride stops being dead time between two places and becomes a place of its own.
Tesla integrates Grok Bot into its vehicles for the ultimate personal assistant
Best of all, your Bots follow you into any Cybercab, and presumably your own Tesla, then logs you out automatically when you step out. Anyone can bolt a chatbot onto a screen, but much harder to own the vehicle, the autonomy stack and the assistant at once. It also quietly ties SpaceX’s Super Intelligence business to Tesla’s fleet, after Tesla converted its xAI stake into SpaceX equity. The relationship between those two companies is getting harder to describe as separate.
This is also where the hard questions start, because an agent that can spend your money in a vehicle other people also ride in needs some answers. How does it handle a voice it shouldn’t trust? What gets recorded, who can see it, and for how long? What happens when a rider leaves halfway through a task?
If Tesla gets those answers right, the scoreboard changes. We have been counting Cybercabs and wait times. The more telling number may be what riders accomplish per trip. That is data almost no one else will ever have, and it is the real reason to watch Grok @bot.

Why Elon Musk’s target date for buying an Optimus robot is harder than it sounds
Musk says China’s magnet export ban cost Optimus months, and robot hands remain shockingly hard.
Elon Musk says China’s export curbs on magnets used in electric motors set back Tesla’s Optimus program by two to three months, and that the robot’s hands remain the hardest part of the project. He made the comments Saturday during a live interview with Tesla Owners Silicon Valley at the X Takeover event at Giga Texas, in front of roughly 2,000 attendees. The Optimus discussion begins around the 49 minute mark of the stream.
On the hands, Musk was blunt and noted that a general purpose humanoid needs fine motor skills that are “incredibly difficult to get right. Shockingly difficult,” he said in the interview. He pointed to a problem he says no one has demonstrated yet: “One of the hardest things also generally is to do precision and force at the same time,” such as driving a small self tapping screw into wood. Touch sensors add another layer, since it is “actually kind of hard to get touch sensors that elastically deform and can handle high cycle life and it won’t just break after a few thousand cycles.”
He also took aim at rival robot videos. “Any complicated looking robot demo, it’s a canned demo. It’s not real,” Musk said, adding that real AI means showing a robot something it has never seen and watching it still cope, the way FSD handles a city it has never driven.
Musk expects the Optimus ramp to be slower than a new vehicle production ramp. “The initial part of that S curve of production ramp is going to be very slow at the beginning,” Musk said, partly because “unlike cars, there’s no pre existing supply chain for robot stuff.” That echoes his July reply on X that Optimus production “will be extremely slow at first, as everything is new.”
The magnet disclosure puts a number on a problem Musk first raised in 2025. He said China “prevented the export of magnets for use in electric motors” and that it “set back the Optimus program by like two or three months.” Then he added: “We had robots with no arms.” Tesla’s fix is to bring the supply chain home. “You’ve got to be able to make all the parts domestically,” he said. Teslarati reported in April 2025 that Musk tied the issue to permanent magnets in the arm actuators, where motors have to be as small as possible.
Tesla Optimus V3 hand and arm details revealed in new patents
Production is moving regardless, with a reported internal goal of more than 1,000 a week by the end of 2026. Teslarati recently covered how Tesla is certifying supply partners in China for Optimus parts, while the company’s hand design has been the subject of new patent filings.
Musk has said he wants Optimus available to the public by late 2027, though Tesla has not confirmed that date or published updated production figures.

Elon Musk drops a Thanksgiving hint about Starship’s biggest test yet
Elon Musk says Starship Flight 15 will try to catch the ship itself, a first.
Elon Musk says SpaceX’s next Starship flight will try something nobody has done before, by catching the ship itself. Speaking to roughly 2,000 people at the X Takeover event at Giga Texas on Saturday, Musk said Flight 15 is about four to six weeks away and “probably launches a little bit before Thanksgiving, is my guess.”
That is a slip from earlier reporting, which had pointed to a launch as early as October 19. Musk explained why the date keeps moving. “We’re making a bunch of improvements to the rocket between every flight,” he said, adding that there are often hundreds, sometimes thousands, of small changes. This time the list is short, “but some of them take a fair bit of work and we’ve got to go inside the tank to make some of these changes.”
“We’re going to try to catch the ship, which is a super big deal,” Musk said. “If we do so, that’ll be the first time that there’s been full recovery of an orbital class rocket.” SpaceX has already caught the Super Heavy booster with the tower’s mechanical arms, and has talked about catching the ship since late 2025, but the upper stage has never been caught.
Musk also laid out what comes after. “The next big milestone would be to refly both the booster and the ship,” he said, describing a Flight 16 where “all parts of an orbital rocket are reflown.”
The reason SpaceX wants this comes down to cost and cadence. Every Starship ship so far has ended its flight in the ocean, and SpaceX expects most of those water landings to end in fireballs. A ship that returns to Starbase intact can be inspected and flown again. SpaceX’s IPO filing, says Starship V3 is designed to deliver 100 metric tons to orbit in a fully reusable configuration, that SpaceX aims to cut the cost to reach orbit by 99% or more versus the historical average, and that tower catches should allow “multiple launches per day.”
The payoff goes beyond cheaper launches. The next generation Starlink V3 satellites are too large for Falcon 9 and can only fly on Starship, which can carry up to 60 per flight. Flight 14 on September 28 deployed the first 26 of them after Starship reached orbit despite an early engine shutdown, as Teslarati reported. Musk blamed engine computer software, and said the heat shield “was extremely robust,” which he claimed in August had solved Starship’s biggest challenge.
NASA’s Moon plans depend on the same capability. NASA’s inspector general has described a lander mission that needs a propellant depot in low Earth orbit and more than 10 tanker flights, with SpaceX targeting one tanker launch every six days. That schedule only works if ships and boosters come back fast and fly again. Also, ship to ship propellant transfer has not been attempted yet.
One interesting hurdle yet to be explored is bringing the ship back to the launch site, with reentry over land, which will undoubtedly come with a lot of aviation safety reviews.
