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.

- 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.

Elon Musk’s xAI bets $20B on Mississippi with 2GW AI data center project
The project is expected to create hundreds of permanent jobs, dramatically expand xAI’s computing capacity, and further cement the Mid-South as a growing hub for AI infrastructure.
Elon Musk’s xAI plans to pour more than $20 billion into a massive new data center campus in Southaven, Mississippi, marking the largest single economic development project in the state’s history.
The project is expected to create hundreds of permanent jobs, dramatically expand xAI’s computing capacity, and further cement the Mid-South as a growing hub for AI infrastructure.
xAI goes MACROHARDRR in Mississippi
xAI has acquired and is retrofitting an existing facility in Southaven to serve as a new data center, which will be known as “MACROHARDRR.” The site sits near a recently acquired power plant and close to one of xAI’s existing data centers in Tennessee, creating a regional cluster designed to support large-scale AI training and inference.
Once completed, the Southaven facility is expected to push the company’s total computing capacity to nearly 2 GW, placing it among the most powerful AI compute installations globally. The data center is scheduled to begin operations in February 2026.
Gov. Tate Reeves shared his optimism about the project in a press release. “This record-shattering $20 billion investment is an amazing start to what is sure to be another incredible year for economic development in Mississippi. Today, Elon Musk is bringing xAI to DeSoto County, a project that will transform the region and bring amazing opportunities to its residents for generations. This is the largest economic development project in Mississippi’s history,” he said.
xAI’s broader AI ambitions
To secure the investment, the Mississippi Development Authority approved xAI for its Data Center Incentive program, which provides sales and use tax exemptions on eligible computing hardware and software. The City of Southaven and DeSoto County are also supporting the project through fee-in-lieu agreements aimed at accelerating development timelines and reducing upfront costs.
Founded in 2023 by Elon Musk, xAI develops advanced artificial intelligence systems focused on large-scale reasoning and generative applications. Its flagship product, Grok, is integrated with the social media platform X, alongside a growing suite of APIs for image generation, voice, and autonomous agents, including offerings tailored for government use.
Elon Musk highlighted xAi’s growth and momentum in a comment about the matter. “xAI is scaling at an immeasurable pace — we are building our third massive data center in the greater Memphis area. MACROHARDRR pushes our Colossus training compute to ~2GW – by far the most powerful AI system on Earth. This is insane execution speed by xAI and the state of Mississippi. We are grateful to Governor Reeves for his support of building xAI at warp speed,” Musk said.
Tesla’s Head of AI, Ashok Elluswamy, says that something that was expected with version 14.3 of the company’s Full Self-Driving platform has already partially shipped with the current build of version 14.2.
Tesla and CEO Elon Musk have teased on several occasions that reasoning will be a big piece of future Full Self-Driving builds, helping bring forth the “sentient” narrative that the company has pushed for these more advanced FSD versions.
Back in October on the Q3 Earnings Call, Musk said:
“With reasoning, it’s literally going to think about which parking spot to pick. It’ll drop you off at the entrance of the store, then go find a parking spot. It’s going to spot empty spots much better than a human. It’s going to use reasoning to solve things.”
Musk said in the same month:
“By v14.3, your car will feel like it is sentient.”
Amazingly, Tesla Full Self-Driving v14.2.2.2, which is the most recent iteration released, is very close to this sentient feeling. However, there are more things that need to be improved, and logic appears to be in the future plans to help with decision-making in general, alongside other refinements and features.
On Thursday evening, Elluswamy revealed that some of the reasoning features have already been rolled out, confirming that it has been added to navigation route changes during construction, as well as with parking options.
He added that “more and more reasoning will ship in Q1.”

More uses of reasoning will be shipped later this quarter, a big tidbit of info as we wait v14.3 https://t.co/jty8llgsKM

Interestingly, parking improvements were hinted at being added in the initial rollout of v14.2 several months ago. These had not rolled out to vehicles quite yet, as they were listed under the future improvements portion of the release notes, but it appears things have already started to make their way to cars in a limited fashion.
Tesla Full Self-Driving v14.2 – Full Review, the Good and the Bad
As reasoning is more involved in more of the Full Self-Driving suite, it is likely we will see cars make better decisions in terms of routing and navigation, which is a big complaint of many owners (including me).
Additionally, the operation as a whole should be smoother and more comfortable to owners, which is hard to believe considering how good it is already. Nevertheless, there are absolutely improvements that need to be made before Tesla can introduce completely unsupervised FSD.

Tesla’s Elon Musk: 10 billion miles needed for safe Unsupervised FSD
As per the CEO, roughly 10 billion miles of training data are required due to reality’s “super long tail of complexity.”
Tesla CEO Elon Musk has provided an updated estimate for the training data needed to achieve truly safe unsupervised Full Self-Driving (FSD).
As per the CEO, roughly 10 billion miles of training data are required due to reality’s “super long tail of complexity.”
10 billion miles of training data
Musk comment came as a reply to Apple and Rivian alum Paul Beisel, who posted an analysis on X about the gap between tech demonstrations and real-world products. In his post, Beisel highlighted Tesla’s data-driven lead in autonomy, and he also argued that it would not be easy for rivals to become a legitimate competitor to FSD quickly.
“The notion that someone can ‘catch up’ to this problem primarily through simulation and limited on-road exposure strikes me as deeply naive. This is not a demo problem. It is a scale, data, and iteration problem— and Tesla is already far, far down that road while others are just getting started,” Beisel wrote.
Musk responded to Beisel’s post, stating that “Roughly 10 billion miles of training data is needed to achieve safe unsupervised self-driving. Reality has a super long tail of complexity.” This is quite interesting considering that in his Master Plan Part Deux, Elon Musk estimated that worldwide regulatory approval for autonomous driving would require around 6 billion miles.
FSD’s total training miles
As 2025 came to a close, Tesla community members observed that FSD was already nearing 7 billion miles driven, with over 2.5 billion miles being from inner city roads. The 7-billion-mile mark was passed just a few days later. This suggests that Tesla is likely the company today with the most training data for its autonomous driving program.
The difficulties of achieving autonomy were referenced by Elon Musk recently, when he commented on Nvidia’s Alpamayo program. As per Musk, “they will find that it’s easy to get to 99% and then super hard to solve the long tail of the distribution.” These sentiments were echoed by Tesla VP for AI software Ashok Elluswamy, who also noted on X that “the long tail is sooo long, that most people can’t grasp it.”
