Have you studied the fluid dynamics at school? Inside the ISS, 250 miles above the earth, the Soft Cell experiment shows what happens when one fundamental force disappears: gravity. And when gravity turns off, fluids reveal behaviors we never see on Earth: - Water becomes perfect spheres - No convection — patterns appear with mathematical purity - Mixing slows to near-zero, enabling precision at the atomic scale - Interfaces behave like living sculptures Microgravity becomes the cleanest physics lab in existence. Why it matters (real impact): + 20× more ordered protein crystals → better drug design + 10–100× more uniform materials → higher-performance semiconductors & alloys + More accurate rocket fuel slosh models → safer launches + Improved climate and turbulence simulations + Better life-support and water recovery systems for spaceflight This isn’t sci-fi — it’s industry-changing science happening right now. The Soft Cell proves one thing: ✨ Sometimes nature shows its most elegant physics only when we leave Earth behind. #SpaceTech via @oxford.mathematics #FluidDynamics #Innovation #Physics #ISS #Engineering #AdvancedMaterials #PharmaInnovation #Aerospace #DeepTech #Research #FutureOfScience

Many leaders still think of space as a distant frontier. That mindset is quickly becoming outdated. The commercial space economy is no longer just about rockets and missions. It is becoming a new layer of infrastructure that is already reshaping industries on Earth—from agriculture and telecommunications to logistics, finance, energy, and national security. What changed? Access and economics. Reusable launch systems, private investment, smaller and more powerful sensors, and growing demand for data have transformed space from a government-led effort into a rapidly expanding commercial platform. History shows a clear pattern: when access improves, innovation accelerates. We saw it with computing, the internet, mobile, cloud, and AI. Space is following the same path. The question leaders should be asking is not, “Are we in the space industry?” The real question is: How will space-enabled capabilities change the way value is created in our industry? Organizations that recognize this shift early can form partnerships, experiment with new capabilities, and build advantage while the market is still taking shape. Those who wait until the opportunity is obvious may find themselves competing on someone else’s terms. In my latest article, I explore why the commercial space frontier deserves far more attention in the boardroom and what leaders should be doing now to anticipate the opportunities ahead. #SpaceEconomy #SpaceTech #Innovation #Leadership #FutureOfBusiness #HardTrends #AnticipatoryThinking

🌍 The Next Global Powers Won’t Be Decided on Earth They’ll be the ones building infrastructure in orbit, on the Moon & beyond. Space is no longer just a scientific pursuit, it's a strategic high ground and an economic multiplier. And countries are voting with their wallets. 📊 National Space Budgets 2024 Highlights (approximate): 🔹 USA: $62B+ (NASA + DoD + private subsidies) 🔹 China: $12B – rapidly expanding lunar and military capability 🔹 EU (ESA): $9.3 B – collaborative but fragmented 🔹 Japan: $4.9 B – burgeoning private sector 🔹 India (ISRO): $1.9 B – high ROI, low-cost mission excellence 🔹 UAE, South Korea, Japan, Australia: All investing & expanding Over 100 nations now have active space programs or satellite interests. The pattern is clear: those who invest upstream today will own downstream value tomorrow in communications, climate intelligence, AI in space, defense resilience, lunar logistics, and in-space manufacturing. At the frontier, innovation follows infrastructure and infrastructure follows budget. What do MRI machines, GPS, solar panels, and water purification tech have in common? They all trace their roots to space program investments. 🔹 For every $1 invested in NASA, the U.S. economy gains $7–$14 in return via tech spinoffs, high-skill jobs, and industry stimulation (NASA Tech Transfer Program). 🔹 The global space economy surpassed $546 billion in 2023, and is projected to reach $1 trillion by 2030 (McKinsey & Space Foundation). 🔹 Countries with top space investments (USA, China & EU) lead in AI, quantum computing, aerospace & precision manufacturing proving space tech is a gateway to multi-sector innovation. 🔹 Over 1,600 commercial products have spun off from NASA technologies alone including memory foam, infrared ear thermometers, and fire-resistant materials. 🌐 Nations that dominate space lead in dual-use technologies (military + civilian applications) and benefit from national security, data sovereignty, and exportable tech IP. 💡 Investing in space isn't optional—it's a strategic move to future-proof economies. Let's talk: Which space-originated tech do you think had the biggest impact on Earth? Innovation has gravity & it's orbiting the nations willing to commit. #SpaceEconomy #NationalBudgets #OrbitalInfrastructure #SpaceInnovation #GeoStrategy #AerospaceLeadership #NewSpace #GovernmentInvestments #DeepTech #SpacePolicy #MoonToMars #SpaceDominance

For the first time in over five decades, humans are returning to lunar space. NASA’s Artemis II mission will send four astronauts on a 10-day journey around the Moon. This is not a landing mission, It’s a test flight, a critical step toward sustained human presence beyond Earth. The broader context is important, Moon is no longer just symbolic. It represents: • Access to rare resources • Potential refueling infrastructure for Mars missions • Strategic positioning in space At the same time, China has announced its own plans to land humans on the Moon by 2030. This signals the beginning of a new phase in space exploration, one driven by both science and geopolitics. The next decade in space will likely be defined not just by exploration, but by competition.

At Arlula we saw 2025 reshape Earth Observation. In 2026 I see 3 key trends shaping the industry. 1.) From pixel sales to satellite services Most major EO operators are moving beyond "imagery-as-a-product" toward hardware-led and "Satellite-as-a-Service models". Control, availability, and tasking flexibility now matter as much as resolution. 2) The rise of sovereign EO programs Civil, defence, and intelligence organisations are investing heavily in national EO capability. More than 40 countries have announced plans to build or expand sovereign constellations, driven by resilience, security, and assured access. 3) Virtual constellations became the default model GEOINT strategies are being rewritten around hybrid access with a mix of commercial capacity and sovereign systems, orchestrated together rather than treated as separate pipelines. Taken together, these shifts are changing; - How satellite imagery is generated, - Who controls access, - Who the real buyers are, - And how EO systems need to be architected. Ten years ago, EO was optimised for selling pixels. The next decade will be about operating infrastructure at scale, across constellations, missions, and algorithms. That’s the gap Earth Observation Data Infrastructure (EODI) is starting to fill. #EarthObservation #GEOINT #DualUse #SovereignCapability #EODI

Artemis is not (just) about the Moon. It is about building the operating system for a sustained human presence beyond Earth. For all the attention on launches and landings, the more important shift is structural. The Artemis program marks a transition from singular missions to repeatable capability. Logistics, refuelling, interoperability, and mission cadence are the real milestones. The Moon is the beta test. If this is an operating system, its contours are already visible. Standardised docking interfaces, refuelling protocols, and open communication layers form the APIs of space. Platforms like the Lunar Gateway act as routing nodes, while commercial landers function as modular components. What is being built is not a mission stack, but an extensible architecture. What is emerging is a different execution model. NASA is no longer the sole builder. It is the architect and anchor client. The hardware layer is increasingly driven by firms like SpaceX and Blue Origin, where iteration cycles are faster and capital is deployed with a different risk tolerance. NASA optimises for assurance through redundancy. The private sector optimises for progress through iteration. The result is not a compromise, but a reconfiguration of how national capability is delivered. This model is not without friction. Timelines slip, systems fail testing, and sustainability standards are still being negotiated. Yet even delays are being absorbed into a system designed for iteration rather than perfection. That architectural choice does not just shape how missions are built. It determines who gets to participate, and on what terms. Competing frameworks are now crystallising, including efforts such as the Chinese Lunar Exploration Program. But framing this purely as a race misses the deeper dynamic. Space has always evolved through a mix of competition and cooperation. The International Space Station remains one of the most complex joint engineering projects ever undertaken, even as geopolitical conditions have shifted. Even at moments of terrestrial tension, collaboration had persisted, including Russian launches carrying American astronauts. The real contest is not footprints on regolith. It is whose technical standards, safety norms, and resource frameworks become the default for others to adopt. Because in the end, the advantage will not lie in a single mission, but in the architecture that makes many missions possible. After all in the long arc of spaceflight, leadership won’t be measured by who arrives first, but by whose standards become the foundation for what comes next.

NASA - National Aeronautics and Space Administration NASA has committed $20 billion to build a permanent base on the Moon, with the goal of establishing a sustained human presence by 2033. According to NASA Administrator Jared Isaacman, the project will unfold in phases, beginning with robotic and uncrewed missions through 2029 to scout the lunar surface and test power systems. By 2029 to 2032, semi‑permanent infrastructure such as solar and nuclear power stations, upgraded rovers, and early habitation modules will be assembled. According to ABC News, the program will cost about $20 billion over seven years and accelerates the Artemis schedule, with Artemis IV and V missions slated for 2028 to begin regular astronaut landings. NASA plans to conduct crewed landings every six months, gradually building the base with the help of commercial partners like SpaceX and Blue Origin. The lunar base will feature pressurized rovers, nuclear power systems, and habitats designed for long‑term occupation. Officials emphasized that the goal is no longer just “flags and footprints” but to stay, positioning the Moon as a proving ground for eventual missions to Mars.

Cancer cells proliferate much more quickly in microgravity. Pr. Chunhui Xu from Emory University considered that if cardiac cells respond to microgravity in the same way cancer cells do, space-based research could hold the key to accelerating the development of cell-based regenerative therapies for heart disease. She said that research on the ISS could allow to develop a new strategy to generate cardiac cells more efficiently with improved survival when transplanted into damaged heart tissue. Her project EAGLE (engineering heart aggregates by leveraging microgravity)—launched on Space X Crew-8 mission. When the live cells were returned to Earth, Xu and her team found the cells had survived the trip, showing that functioning heart muscle cells could be generated in space. Microgravity increased gene expression involved in cardiac cell development and proliferation. Xu said: ‘Metabolic pathways that we have seen in the proliferation and survival of cancer cells were also activated in the cardiac cells in space,” Such space-based research could lead to significant advances in the Earth-based production of cardiac cells for regenerative therapies to treat heart disease.

The U.S. military is investing in reusable reentry capsules designed by space startups to return cargo from space and deliver it to precise locations on Earth. These vehicles are seen as key tools for future space operations and logistics, as the Pentagon explores new methods to streamline transportation in space. Startups specializing in reentry vehicle technology, such as Inversion Space and Outpost Space, recently secured more than $100 million in defense and private investments under the Strategic Funding Increase (STRATFI) initiative. This program, aimed at assisting small businesses in transitioning from development to full-scale production, combines up to $15 million in Small Business Innovation Research (SBIR) investment with matching funds from government agencies and private sources, bringing the potential total to $60 million. Some STRATFI contracts exceed the $60 million threshold. Inversion Space, based in California, disclosed that its agreement is valued at $71 million, which will support the development of autonomous reentry vehicles and demonstration missions tailored to military customers. “Autonomous reentry vehicles that can be called to Earth on demand will transform logistics and provide rapid access to even the most remote parts of the globe,” said Justin Fiaschetti, chief executive of Inversion Space. The military’s interest in reentry capsule technology is closely tied to the Air Force’s ambitious Rocket Cargo program, which is investigating how to use space launch vehicles to transport supplies or other cargo across vast distances on Earth. Reusable reentry capsules are a cornerstone of this effort, enabling the delivery of supplies through controlled de-orbiting and descent from space using parachutes or other mechanisms for precise drops. #Cargo #Space #Delivery #STRATFI Illustration of Outpost's Carryall reentry capsule.

Moonshot Space 𝗶𝘀 𝗼𝘂𝘁 𝗼𝗳 𝘀𝘁𝗲𝗮𝗹𝘁𝗵. and I want to use this moment to raise a conversation the space industry keeps avoiding: Since Sputnik, the fundamental principle behind launch hasn’t changed: a payload sitting on top of fuel, that pushes more fuel, that pushes even more fuel. Physics dictate the same ratio everywhere: less than 4% payload, more than 96% fuel and structure. Soyuz, Falcon, Electron, Starship- different designs, same dependency. Brilliant engineering. But it creates one of the strangest supply chains humanity still relies on. And it gets even stranger with pricing: launch is sold universally per kilogram. One kilogram of a human equals one kilogram of bulk materials. For space folks, it seems natural. For outsiders it is absurd. Take a simple example: flying an 80 kg person from Fiji to LAX costs about $1,500. Shipping 80 liters of Fiji Water the same distance costs almost nothing. Same weight. Completely different logistics profile. But in space, we treat them the same. This is why we built Moonshot. We’re developing an electromagnetic launch system for non-sensitive, high-G cargo, creating a dedicated logistics layer for propellants, steel coils, consumables, components, and raw materials. Not to replace rockets, but to complement them. Maersk doesn’t replace DHL; DHL doesn’t compete with Uber. Each serves a different logistics profile. Same here. We’ll be at least an order of magnitude cheaper, because electrons cost less than propellant. We’ll operate at far higher cadence (8 launches per day), limited only by recharge time. The result: a real supply chain for the in-orbit economy. In the coming months, we’ll share more details and images of the systems we’re building, and hopefully announce our first commercial hypersonic-testing contract based on the prototype now under construction. We’re fortunate to be building this in Israel ✡️,  with a team that has already built some of the most advanced operational hypersonic and aerospace systems that works in the upper and outside earth atmosphere. Surrounded by deep expertise in electromagnetics, and complex operational programs. The talent here is a major part of why we can move fast. Rockets will lift the workers and the cranes. EM systems will deliver the materials. Together, we can build orbital infrastructure that finally makes economic sense. If you’re working on the future in-orbit economy and believe space logistics must evolve beyond a single modality — let’s connect.
