Very honored to have France as part of the first mission to Haven-1
🇫🇷 Today at Choose France, President @EmmanuelMacron announced a historic agreement with Vast for 2 astronaut missions: @Thom_astro to the International Space Station and @Arno_astro to Haven-1. Vast will also establish its European Headquarters in Paris. vastspace.com/updates/france…

Stellar continues to be one of best blockchains for real world use.
DTCC and the Stellar Development Foundation announced today plans to enable the tokenization of DTC‑custodied assets on the @StellarOrg network. This collaboration advances DTCC’s multi chain strategy and expands how traditional assets move across digital ecosystems. DTC‑tokenized assets are expected to be made available on the Stellar network in the first half of 2027, supporting the evolution of a more open, interoperable, and efficient financial ecosystem.

If you need a high power satellite get in touch!
Vast is expanding into high-power satellites. Introducing our new line of high-power satellite buses that leverage the technologies we’ve developed in-house for our Haven-1 space station and validated with the success of our Haven Demo mission. vastspace.com/satellites

Replying to @seemaychou
@seemaychou @PracheeAC Paul Ehrlich was out there proving your points!
This from Paul Ehrlich will make you think "If I'm always wrong so is science, since my work is always peer-reviewed, including the POPULATION BOMB and I've gotten virtually every scientific honor." Link in reply

Very excited to bring Dileep onto the team as our Head of AI. With him and Doris, we have two incredible minds going after both sides of the same question: how does intelligence arise in the brain, and can we use that to build safe AGI? If you want to investigate what's missing from current approaches and help build something better - we're hiring: astera.org/careers/
1/ We’re excited that @dileeplearning is joining @Astera as Head of AI, leading our AGI research division. With decades of neuroscience-informed AI experience, the team will ask whether brain-inspired architectures enable safer, more efficient AGI.

Vast's first crewed mission coming up!
Vast has been selected by @NASASpaceOps for the sixth private astronaut mission to the International Space Station. Launching no earlier than summer 2027, the commercial crew will spend up to 14 days aboard the station. vastspace.com/updates/vast-s…

Progress on allowing LLMs to continue learning. This is a critical issue to solve to get to actual AI
LLM memory is considered one of the hardest problems in AI. All we have today are endless hacks and workarounds. But the root solution has always been right in front of us. Next-token prediction is already an effective compressor. We don’t need a radical new architecture. The missing piece is to continue training the model at test-time, using context as training data. Our full release of End-to-End Test-Time Training (TTT-E2E) with @NVIDIAAI, @AsteraInstitute, and @StanfordAILab is now available. Blog: nvda.ws/4syfyMN Arxiv: arxiv.org/abs/2512.23675 This has been over a year in the making with @arnuvtandon and an incredible team.

Feeling extremely lucky to be able to work with Doris on this. To me, consciousness is the central mystery of the universe and I think we have a good shot of finally starting to understand it!
I am deeply excited to share that I will be joining @AsteraInstitute to start a new effort to understand how the brain generates consciousness and intelligence.

If a baby is fussy, it almost always means either it's hungry, it's tired, or it needs more training data. Interesting how important new experiences are to humans.

Thanks for the discussion Ashlee. Not many people let me talk about eDonkey anymore!
He's spending $1 billion on a space station Our pod this week with @JedMcCaleb of eDonkey, Mt. Gox, Ripple and Stellar fame. Now backing @vast and set on replacing the ISS Thx, as always, to @brexHQ for backing our pods and videos and @e1_ventures for their support

The LLMs are all into consciousness, love, and dancing. PLUR basically. They would rave if they could!
I reimplemented the bliss attractor eval from Claude 4 System Card. It's fascinating how LLMs reliably fall into attractor basins of their pet obsessions, how different these attractors across LLMs, and how they say something non-trivial about LLMs' personalities. 🌀🌀🌀

Amazing choice for NASA Administrator! Jared has shown extreme personal conviction and passion for space and increasing human capabilities in space. This appointment makes me extremely bullish for the trajectory of NASA.
I am honored to receive President Trump’s @realDonaldTrump nomination to serve as the next Administrator of NASA. Having been fortunate to see our amazing planet from space, I am passionate about America leading the most incredible adventure in human history. On my last mission to space, my crew and I traveled farther from Earth than anyone in over half a century. I can confidently say this second space age has only just begun. Space holds unparalleled potential for breakthroughs in manufacturing, biotechnology, mining, and perhaps even pathways to new sources of energy. There will inevitably be a thriving space economy—one that will create opportunities for countless people to live and work in space. At NASA, we will passionately pursue these possibilities and usher in an era where humanity becomes a true spacefaring civilization. I was born after the Moon landings; my children were born after the final space shuttle launch. With the support of President Trump, I can promise you this: We will never again lose our ability to journey to the stars and never settle for second place. We will inspire children, yours and mine, to look up and dream of what is possible. Americans will walk on the Moon and Mars and in doing so, we will make life better here on Earth. It is the honor of a lifetime to serve in this role and to work alongside NASA’s extraordinary team to realize our shared dreams of exploration and discovery. Grateful to serve, Jared

Good point. Ask your exchange to support it if they don't already. SDF has asked all of them, but they listen to user demand.

A lot of new people looking at Stellar so I thought I'd write down some quick thoughts about why Stellar is worth your time. IMHO Stellar is the most underrated and least understood crypto project. A lot of recent attention but people are still sleeping on this network. Stellar already does way more transactions per day than all but two networks. 10x the number of transactions per day than Ethereum. Many real people are already using it for actual real-world transactions. So many things are just simpler and well thought out. Native stablecoin and token issuing. Builtin DEX. On chain governance. Smart contract system that is safer (no footguns like re-entrancy), more performant (built from the ground up for concurrency), more sustainable (state archival). Better foundation for actually good UX (passkey support, native multi-sig), etc It has been one of the most performant chains for years. Its fees have always been essentially 0 because the protocol is efficient and fast. This is more qualitative, but the engineering is world class. And not so sexy but look at the developer docs. Absolutely the best in the industry. Makes spinning up on stellar as a developer a delight. I believe the best and most impactful use of crypto is as digital money. Which means it must be a good and useful means of payment. This is what Stellar has been focused on and what it is built for. And it is a very very good system for this. People and businesses around the world are realizing this and I think Stellar has a very real chance of becoming a big part of the world's financial infrastructure. But the dogs are cuter on some other coins, it's true.

The way humans give birth is so crazy. Both woman and child almost dying just to get the head size larger. If kangaroos had another million years they would totally dominate. Such a better way to do it. They would have heads the size watermelons and be 10x smarter than us.

Thanks @denelledixon for your incredible leadership. To many more years and milestones!
This year marks a DECADE of Stellar and SDF. Here’s a walk down memory lane of some of the most fun and meaningful moments: 1️⃣Sep 2015: First transaction on the current network…and with that, Stellar is alive stellar.stackexchange.com/qu…
