For example:\n\n* ✈️ A recent supertyphoon damaged $200M of Air Force planes in Guam ([JTWC](https://www.metoc.navy.mil/jtwc/products/atcr/2018atcr.pdf)).\n* 🚢 Ocean cargo ships reroute around so many unpredicted cyclones that they lose $60M of voyage time per ship per year.\n\nIt may seem like your weather app has tons of data to prevent this, but weather apps pretend predicted data is real. Those predictions are based on limited, inaccurate measurements from aging government satellites. Other solutions (weather stations, balloons, drones) aren’t scalable.\n\n![uploaded image](/media/?type=post&id=79524&key=user_uploads/349337/5ce389df-7421-4592-aa8c-dc75b9ba0e7b)\n\n### **🌎 🛰️ Solution**\n\nAfter studying with a NASA expert, we invented a modernized radar satellite, called [Veery](https://careweather.com/tech). We can mass produce Veery at low cost and get orders of magnitude more truth data. Veery’s flat form factor gives it way more solar power and lets it sail on top of the atmosphere for a closer view of the surface. Veery will map ocean surface vector winds, soil moisture, and sea ice globally, every hour, with 100 m - 6 km resolution.\n\n![uploaded image](/media/?type=post&id=79524&key=user_uploads/349337/fe836808-1163-4870-b7d1-7849bbbadb47)\n\n### **🚀 Traction**\n\nIn the last four months, we built and launched the smallest radar satellite in history!

For government customers, Sutter can identify dark fast-moving objects between Earth and the Moon which currently evade detection, a critical issue for national defense and a key need of the Space Force. We are already using Sutter in ground-based observatories and will begin commercial sales of Sutter SDA data next month having tracked dozens of faint moving objects in space already.

We developed an aerodynamic technology for any fixed-wing aircraft that makes it possible to carry more payload, over longer distances - perfect for electric aviation to overcome the limitations of today’s batteries. Our first product is a large cargo drone called AURAE. \n\n![uploaded image](/media/?type=post&id=65921&key=user_uploads/881099/5f0e8973-d450-4958-aff1-e4820d36eae7)\n\n\n### **BATTERIES ARE NOT VERY GOOD**\n\nAviation is incredibly hard to decarbonize, and first generation electric aircraft are proving to be heavy, expensive, complicated, and limited in range. That formula has never been successful in the history of aviation. Could we just wait for better batteries? Not great - emissions keep rising, and progress is incremental - a few % improvement each year means a few % more range... What about better motors, or lighter structures? There’s a few % still on the table there too, sure.\n\nBut if you could _double_ the aerodynamic efficiency, you could double the range that’s possible with today’s batteries. \n\nSeaflight uses Aerodynamic Flow Control. It’s tech that suits today’s operations, manufacturing approaches, and form factors, and we’ve de-risked it to the point where it’s ready to fly. \n\n### **CONTROL THE AIR**\n\n**Thanks to over $2m in backing from the National Science Foundation, the US Air Force, and the Australian Government**, we’ve been able to develop and test our Aerodynamic Flow Control - an active system that pulls more air over the wing when we need it (takeoff and landing), but otherwise adds almost no mass or drag to the aircraft (unlike adding extra propulsion). \n\nBecause we triple the lift only when we need it, we can have smaller wings. Smaller wings mean less drag in cruise, which means much less energy used. \n\n**This is key enabling technology to make electric flight viable.** \n\nOur upcoming large scale flight demonstrator will take to the skies over Australia in early 2026, with a production version to follow. \n\nBest of all, this is universal technology. Every plane has wings… Seaflight’s tech can go on every plane. \n\n![uploaded image](/media/?type=post&id=65921&key=user_uploads/881099/4b0649c0-2cb1-47d2-900d-a8b8791842cf)\n\n\n### **HOW DID WE GET HERE**\n\nWill Sutton and Graham Doig founded Seaflight Technologies heading into the S22 batch. We originally worked on ultra-low-altitude “ground effect” flight. After 6 prototypes and a series of world-first flight achievements, we realized the numbers didn’t add up to viable economics. After pivoting to aerodynamic flow control and developing the new IP, including a test campaign at Caltech, it’s time to make the AURAE flight demonstrator a reality and break some world records for electric flight. \n\n### **About the founder :**\n\nGraham Doig has a PhD in aerodynamics and has worked on electric mobility for 19 years, including 2 world land speed records. He led the aero/range team at EV startup Canoo, and was a Lockheed Martin-endowed professor of engineering in a past life, working on projects with the likes of Tesla and NASA. \n\n### **Lastly, Asks 🙏**\n\nDo you know anyone involved in **logistics** that has already been looking at or using drone technology?\n\nDo you know any **wizards in electric or autonomous mobility** who are looking for a bonkers new professional challenge?", "url": "https://www.ycombinator.com/launches/H9F-seaflight-we-make-the-world-s-most-efficient-airplanes", "votes": 39, "created_at": "2022-09-08T07:48:51.950Z" } ] }, { "id": 26880, "name": "Airhart Aeronautics", "slug": "airhart-aeronautics", "former_names": [], "small_logo_thumb_url": "https://bookface-images.s3.amazonaws.com/small_logos/8754b2c358df7ab9263e0a74ddf008cb7c8cee4d.png", "website": "https://www.airhartaero.com/", "all_locations": "Los Angeles, CA, USA", "long_description": "Airhart is making airplanes anyone can fly.

What we’re building behaves like a drone in some ways, and like a satellite in other ways. Much like satellites, we’re able to provide service for long periods of time, but we’re also much closer to users (we fly at around 70,000 ft / 20 km altitude) and able to maneuver or remain over an area of interest. This makes what we’re building really well suited to applications that require continuous coverage or high-resolution/bandwidth data. Applications include:\n\n* Providing cell service or internet coverage\n* Aerial imagery and mapping\n* Meteorology and atmospheric sensing\n* Emergency response\n\n![uploaded image](/media/?type=post&id=68187&key=user_uploads/1045182/893208ea-fa0f-46bc-9dc7-b93042439b94)\n\n### **How it works**\n\nOur aircraft is battery electric and driven by propellers. It has a large wing for high aerodynamic efficiency and to generate the necessary lift required to fly in the thin air of the stratosphere. The wing is covered in solar cells, during the day, these power the aircraft and charge its batteries. Through the night, battery energy is deployed to continue flight. We repeat this process daily, enabling us to fly for many months without needing to land. Ultimately, battery cycle life is what limits our aircraft’s flight endurance - and we can land, carry out simple maintenance tasks and then re-launch to continue flying.\n\n### **Ask**\n\nWe’re hiring and working with customers!

Contact: [bc@stralis.aero](mailto:bc@stralis.aero)\n\n**Problem - Alternatives Compromise on Range or Cost**\n\nAs other modes of transport decarbonise, aviation’s contribution to global emissions will increase. Based on our first hand experience, we believe other sustainable flight alternatives compromise on:\n\n* Battery Electric - limited range & payload\n* Hybrid Electric - expensive to operate, limited emission reduction\n* Sustainable Aviation Fuel (SAF) - expensive & emits other harmful pollutants (NOx, sulphates, particulates)\n\n**Solution - Hydrogen Electric Propulsion**\n\nWe're convinced hydrogen electric is the cheapest way to rapidly decarbonise 50% of commercial flights.\n\n* How it works - Green hydrogen and air are combined in a fuel cell stack to produce electric power, which is used by an electric motor to turn a propeller. The only thing emitted during this process is water.\n* Our proprietary hydrogen electric propulsion system is 35% lighter than the competition, unlocking useful aircraft ranges at low cost.\n* Our first product is a retrofit of an already certified aircraft, allowing us to get to market quicker and cheaper.\n* We plan to deliver 50,000 of our 48 seat SA-1 aircraft by 2050, generating $850B in revenue.\n\n**Our Backstory**\n\nWe met in 2017 at [magniX](https://www.magnix.aero/), leading teams developing electric aircraft propulsion systems for the world’s first battery powered eBeaver and eCaravan flights. The Stralis team has 85 years of aerospace experience, having developed, flight tested and certified aircraft at GoogleX, [Heart Aerospace (YC W19)](https://heartaerospace.com/), [Ampaire](https://www.ampaire.com/), Airbus, Boeing, Bombardier and Gulfstream.

The graphics have room for improvement!_\n\n**Dispatch** is the first satellite OS. It provides a common software infrastructure to allows fleets of dissimilar satellites to work together:\n\n* **Tasking**: Image geographic areas in visible, infrared, or radar.\n* **Radio and Telecom:** Manage in-orbit networks and signals intelligence collection.\n* **Orbital Security**: Monitor and inspect other space assets.\n\nNew or external software modules can also easily be integrated, rather than being rewritten for each individual satellite. \n\nThere are over 65,000 satellites licensed to be launched by 2030.

Unlike any existing engine, it's efficient at every speed. Because it's efficient at every speed, it can be used in new and different ways. It can launch payloads to orbit 3x cheaper than an all rocket system, or enable a passenger aircraft 3x faster than an airliner.\n\n**Jet Aircraft Stopped Improving in the 1970s**\n\nJet aircraft have powered much of the global economy through trade and commerce since the advent of the Jet Age, yet the technology has not changed foundationally in over 40 years. \n\nModern commercial jets are still using (more or less) the same airframes that were originally designed in the 1970s. The first Boeing 737 flew in April 1967 and the first Airbus A300 flew in October 1972. \n\nJet engines – which are limited by a trade-off between speed and efficiency – have similarly only seen incremental improvements. Newer jet engine designs (like the turbofan) are more fuel-efficient, _but slower_ than older ones (like the turbojet).\n\n**The New Jet Age**\n\n![uploaded image](/media/?type=post&id=79893&key=user_uploads/204090/9797c1b0-0c0e-4889-bdfb-87ec2fea2a34)\n\n_Powered flight starts with the engine. To change flight, you must change the engine._ \n\n**Astro Mechanica has invented a new type of jet engine that is efficient at every speed. We call it the Electric Adaptive Engine and it is not only more fuel efficient than modern jet engines, but 3x faster.** We’ve achieved this by using electric motors to drive the compressor, allowing it to spin at variable speeds and \"adapt\" to its airspeed and combustion cycle. \n\nWe built our proof-of-concept engine in just two months — something that would take the typical aerospace company a year to build. We’re now finishing up our first flight engine in just three months using $500k of off-the-shelf hardware. The next step is to build an airframe over the next 6-8 months to use that engine. We’ll then put it all together and demonstrate supersonic flight in 2025.\n\n**Here’s some photos from that first flight engine build**\n\n![uploaded image](/media/?type=post&id=79893&key=user_uploads/204090/a4f4b133-ce06-4e92-ab14-8de091f0dbf8)\n\n![uploaded image](/media/?type=post&id=79893&key=user_uploads/204090/9f0a9532-00a7-463f-acc4-d16f920ecdfe)\n\n![uploaded image](/media/?type=post&id=79893&key=user_uploads/204090/2f542446-5a56-444f-a600-0ab2c87cc82d)\n\n![uploaded image](/media/?type=post&id=79893&key=user_uploads/204090/ab220bf7-1c8d-45f7-853c-68c153b79233)\n\n![uploaded image](/media/?type=post&id=79893&key=user_uploads/204090/ef311d87-b168-466c-8b45-fd5181671fc5)\n\n**Astro Mechanica’s Master Plan**\n\n![uploaded image](/media/?type=post&id=79893&key=user_uploads/204090/a590551c-a496-47fe-bc9b-e4570cce4cf7)\n\n**Phase 1:** De-risk technology for passenger aircraft certification through applications like space launch\n\n**Phase 2:** Establish manufacturing and operational capacity to offer private flights\n\n**Phase 3:** Scale operational capacity and make supersonic flight affordable\n\n**_Why Are We Starting with Launch?_** Because it is cheaper, easier, and a regulatory hack to supersonic passenger travel. \n\n* Less stringent FAA regulations\n* Fastest and highest return on technical investments\n* Quickest iteration loop with off-the-shelf hardware\n* “Tactical Response” capability\n* “Multi-role” aircraft with commercial and military applications\n\n**_What Are the Benefits of Launching at Speed?_** An increase in payload capacity at a lower cost. We can deliver 3.5x more payload capacity by air-launching a rocket at 800 m/s – that also makes it 3.5x cheaper than launching from the ground.\n\n![uploaded image](/media/?type=post&id=79893&key=user_uploads/204090/3a7a2951-ab7f-4e72-8ef6-ee9211db02e6)\n\n**Contact Us**\n\nReach out to [info@astromecha.co](mailto:info@astromecha.co) for more information.

We are [Ashi Dissanayake](https://linkedin.com/in/ashi-dissanayake) and [Reza Fetanat](https://linkedin.com/in/rezafetanat), the team behind [Spaceium](https://spaceium.com/).\n\n![uploaded image](/media/?type=post&id=81561&key=user_uploads/985204/76cbc58c-243e-410f-99ca-5eaa12bdeb79)\n\n**Here's a brief introduction:**\n\n**Ashi** is an Aerospace Engineer specializing in **Orbital Mechanics and rocket propulsion.** Ashi has worked on real-time simulation models for uncrewed return missions to asteroids and on **NASA-related aerodynamics projects**.\n\n**Reza** is also a space enthusiast and a Mechanical Engineer specializing in **Robotics, structures, and Cryogenics**. Reza has worked on revitalizing the **LR-101 engine, which was used on Atlas, Thor, and Delta launch vehicles.**\n\nWe first met while leading the University of Ottawa's rocketry team, where we built high-powered rockets to send scientific payloads to different altitudes. In our spare time, we enjoyed working together to build rockets in the backyard, sometimes leading to interesting experiences with backyard fires. 🔥\n\nThroughout our careers, we've noticed the constraints on space missions due to the lack of ability to refuel or repair spacecraft in orbit. The current solutions are costly, and a centralized location where spacecraft can refuel and repair is a massive necessity. We are on a mission to build the missing piece of space infrastructure that connects the space superhighway, Just like how service stations were built on Earth back in the day!\n\n# **The problem**\n\nAll spacecraft and space missions face a standard set of challenges. Fuel is a limited and difficult resource to transport. In the event of a significant issue, spacecraft cannot be repaired in space. These challenges have significantly hindered efficiency in current space missions and have been a substantial obstacle in humanity's quest to explore space further. \n\nUnlike a road trip where refueling is common and convenient, spacecraft face a unique challenge. Spacecraft cannot refuel along the way. Instead, they must carry all the fuel required for the mission from Earth. **An overwhelming 85% - 95% of the launch weight is fuel on a typical launch vehicle, with 80-90% burned off to reach orbit.** 🚀\n\nAs a result, spacecraft that transport loads in space (space tugs) can only perform, **on average, 25% as many missions as they're technically capable of due to the absence of refueling in space.** 🛰️\n\nFurthermore, even if a spacecraft wanted to carry additional fuel, it is not easy. Current spacecraft require cryogenic fuels such as liquid oxygen, methane, and liquid hydrogen, which must be stored and transferred at extremely low temperatures of -285°F. 🥶 Environmental factors in space, such as heat and radiation, increase the temperature of these fuels, causing them to boil off (vaporize).\n\nIn addition, **there is no current solution for spacecraft repair**. This means that today's spacecraft must operate flawlessly to maximize efficiency, which is only sometimes the case. For instance, Eutelsat Communications' satellites experienced power loss mid-mission with no option for repair, resulting in a **$30 million** revenue loss. **With Spaceium's multifunction robotic arm, the communication satellite could have been fixed.** 🛠️\n\n# **Solution**\n\n_Automated servicing stations in space 🌎🚀🛰️_\n\nOur primary solution aims to improve space missions' efficiency by addressing refueling challenges. **The developed cryogenic fuel storage and transfer technology is designed to store fuel without any boil-off for multiple years in space.** As a result, spacecraft can now refuel in space, carry more payload, and travel longer distances.\n\nTwo fundamental principles guide our proprietary Zero Boil Off (ZBO) technology. \n\n* Firstly, we prevent heat from entering the system through a unique tank design, insulation, and coating system. \n* Secondly, our innovative multistage closed-loop cooling system evenly removes the heat from the cryogenic fuel and transfers it to radiators, ensuring zero boil-off.\n\n \n\nOur cryogenic storage system is not only efficient but also highly scalable. Our current cooling system is **65% more efficient** than any other cooling system, and our scalable storage system can store up to 30 metric tons of fuel, making it adaptable to a wide range of space missions and requirements.\n\nAfter successfully addressing the challenge of transporting large amounts of space fuel, we turned our attention to developing technology for delivering this fuel to spacecraft in space. This is achieved through the use of a **multifunction robotic arm**. This advanced arm can securely dock with incoming spacecraft and initiate the fuel transfer. **The fluid system built within the arm allows the transfer of different fuel types through the robotic arm**. The built-in thermal system ensures that fuel is transferred to the customer's spacecraft at the correct temperature without any boil-off issues associated with cryogenic fuels in space.\n\nAdditionally, the same robotic arm is versatile enough to handle non-cryogenic fuels as well, providing a comprehensive solution for refueling spacecraft in space.\n\nIn addition to safe and efficient fuel transfer, the robotic arm is equipped with an interchangeable end effector designed for in-space repairs. In-space repairs are achieved through a fully automated robotic arm that can retrieve tools from a stored \"toolbox\" within the system. This innovative feature ensures that even in the event of a significant issue, spacecraft can be repaired in space, minimizing the risk of mission failure and maximizing mission efficiency.\n\nOur vision is to transform the space industry. Starting in Low Earth Orbit (LEO), our servicing infrastructure will progressively expand to encompass Geostationary Earth Orbit (GEO), the moon, and eventually Mars. We are on a mission to empower space missions to go further, explore more, and achieve what was once deemed impossible.\n\n**Who can benefit from our service stations in space** \n\n* **Launch vehicles** \n* **Orbital transfer vehicles** \n* **Space tugs** \n* **Moon landers** \n* **Satellites**\n\n# **Ask**\n\n* **Feedback, comments, or questions.** Reach out to us to learn how we can help with your missions.\n* **Warm Intros.** If you know or work with any launch providers, space companies, or satellite providers who could benefit from our service, please introduce us to them. 🛰 \n* **Follow.** Follow us on [LinkedIn](https://www.linkedin.com/company/spaceium-inc), [X](https://x.com/SpaceiumInc).

We are going to deliver the capabilities that the DoD wants in a form factor that’s 10x smaller and 10x cheaper.\n\nOur missiles will be compatible with existing launch platforms, deliver smaller payloads at high subsonic speeds, and take out ships hundreds of miles away. We’re focusing on ground and ship-launched variants to start but will expand into air-launched versions, as well as versions with extended ranges and different payloads.\n\n**Why we’re doing this**\n\nA war with China in the Taiwan Strait would look nothing like what we've seen in Ukraine or the Middle East. Wargames within DoD and military experts are in agreement that the most useful weapons in such a conflict would be long range anti-ship weapons or cruise missiles.\n\nThe United States is not adequately prepared. In a potential conflict, our stockpiles will run out in weeks, and we currently don’t have the industrial capacity to build at a rate that could win a war, much less deter China. Higher-ups in DoD are waking up to the problem, and generals such as Major General Cameron Holt and officials such as Chairman of the House Select Committee on China Mike Gallagher have echoed this sentiment.\n\nRecent conflicts in the Middle East and Ukraine have shown that our weapons are too large, too expensive for the wars of today. Existing anti-ship cruise missiles are low-volume, multi-million dollar, 3,000 lb behemoths meant to take out large cruisers and destroyers.\n\nBut Chinese shipbuilding capability is far superior to ours, and we can’t make enough anti-ship missiles to counter. In addition, huge missiles aren’t needed to take out the smaller corvettes and frigates that make up the People’s Liberation Army Navy. And $3M missiles make even less sense to take out swarms of $200k small, unmanned surface vessels.\n\nThe DoD needs smaller, less expensive cruise missiles, and lots of them! But no one has delivered on that promise yet.\n\n**How we know how to do this**\n\nBoth of us have worked at multiple defense and munitions startups. [Devan](https://www.linkedin.com/in/devanplantamura) is an Army Psychological Operations and Navy combat veteran and has deep experience in operations and business development at well-funded defense startups. [Alex](https://www.linkedin.com/in/alextseng1/) was the first engineering hire at an earlier missile startup, built autonomous systems at Rivian and Stanford, and worked on turbojets at CSULB.\n\n**Where we’re at now**\n\nWe spent the summer building multiple prototypes and flight-testing them in the Mojave. In 11 weeks, we went from starting the company to flight testing with our own design. We are on track to deliver early working missile systems to our first customers by mid-2025.\n\nWe believe our vision for anti-ship cruise missiles can help fill the munitions gap that the US faces. At Ares, we would never wish for a war to occur. But by helping to rebuild our defense industrial base, we can make sure the United States is prepared to stop a conflict and save countless lives.\n\n**Our Ask**\n\nWe are looking for extremely talented aerospace engineers to help bring our prototypes to fruition. If you know any aerodynamics, propulsion, or GNC engineers who are interested in building something incredibly cool and want to make a positive difference in geopolitics, please send them our way!\n\n![uploaded image](/media/?type=post&id=83257&key=user_uploads/1087615/44076741-cbe9-4762-af9b-84e96db0c32e)\n\n", "url": "https://www.ycombinator.com/launches/Ler-ares-industries-building-low-cost-cruise-missiles", "votes": 75, "created_at": "2024-08-20T23:21:53.587Z" } ] }, { "id": 29808, "name": "Starcloud", "slug": "starcloud", "former_names": [ "Lumen Orbit, Inc.", "Lumen Orbit", "Star Cloud" ], "small_logo_thumb_url": "https://bookface-images.s3.amazonaws.com/small_logos/e9c9b9996bb500ee171134f1e1a0a83f5d48bec3.png", "website": "https://www.starcloud.com/", "all_locations": "Seattle, WA, USA", "long_description": "Starcloud is building data centers in space, initially to provide GPU compute to other satellites, and later to address the rapidly growing demand for energy caused by the deployment of AI.

When handed stacks of government requirements, program managers are expected to figure it out - with no guidance. Currently, they:\n\n   ❌ Waste hours searching for the correct document version (often government counterparts don’t know)\n\n   ❌ Sort through thousands of pages to find relevant information or requirements\n\n   ❌ Avoid the headache by offloading to busy engineering teams\n\n   ❌ Cross their fingers that they didn’t miss any requirements that will hurt the team in the future\n\n**The Solution**\n\nConsus transforms document compliance from a burden to a competitive advantage:\n\n   ✅ Instant access to verified, active documents\n\n   ✅ Automatic alerts for document updates affecting your projects\n\n   ✅ AI-powered insights that surface relevant requirements in minutes\n\n   ✅ One-click requirement extraction \n\nWe work directly with government organizations to identify active document revisions.

General (Ret.) John Shaw, US Space Force_\n\nIn October 2021, China’s Shijan-21 was launched into Geosynchronous Transfer Orbit (GTO), where it docked with a navigation satellite, moved the asset beyond the typical graveyard orbit, and returned to Geosynchronous Earth Orbit (GEO). This capability far exceeds what the American space market has been able to achieve, and large providers are far behind schedule.\n\n**_Access to Space_**\n\nRecently, a mission was performed by the government to test how long it would take to put an emergency military asset into orbit. The acceleration effort led to the launch of a vehicle in 5 months. While this was faster than previous efforts, a lot can happen in 5 months, especially during times of unrest. The US Space Force needs a high-thrust, high-efficiency vehicle to perform dynamic space operations in hours to be able to protect our critical satellite infrastructure.\n\n**_In-Space Propulsion_**\n\nCurrent in-space propulsion systems rely on one of the following, both of which have significant downsides:\n\n* Storable propellants\n* Electric propulsion\n\nStorable propellants can only provide a few pounds of thrust (\\~3.75 lbf) and modest efficiency at 250 sec to 320 sec of specific impulse (Isp). Although the engines are simple and reliable, the performance is not adequate for responsive maneuvers. Meanwhile, electric propulsion boasts extremely high Isp (1300 sec), but the thrust is extremely low, coming in at less than 0.007 lbf.\n\n### **The Solution**\n\nTaking advantage of the decreasing costs of launch services and chemical propulsion development over the last 15+ years, Orbital Operations is building a high-thrust, reusable space vehicle that will be stationed in orbit to perform rapid dynamic space operations for the military, executing and finalizing orbital maneuvers in hours vs months. There are 3 key pieces of development:\n\n* The Cryo-Cooler\n* The Rocket Engine\n* The Vehicle\n\n**_The Cryo-Cooler (BOREAS)_**\n\nThe first milestone to unlock dynamic space operations is to develop a functioning cryogenic cooling system capable of storing high-efficiency propellants for an indefinite amount of time while in space. With a letter of support from NASA, we have access to the 15+ years of research and development they have put together on cryogenic fluid management and have the capabilities to commercialize the technology. Using a Reverse Brayton Cycle (RBC), turbomachinery, and advanced manufacturing techniques, we can develop a commercially viable 20 Kelvin cryocooler.\n\n![uploaded image](/media/?type=post&id=87855&key=user_uploads/2288560/eeb9f9e4-d674-458e-804a-f09ea4b7d42b)\n\n\n\n**_Rocket Engine_**\n\nOrbital Operations will develop an in-house chemical propulsion engine capable of >5000 lbs of thrust and a targeted Isp no less than 450 sec.

Zero-G manufacturing is currently at a turning point, transitioning from research to producing materials for use on Earth. The current space infrastructure cannot provide consistent access & return for zero-g manufacturing, and that is where we come in.\n\n**Why produce anything in space at all?**\n\nThe absence of gravity in space means that there is no sedimentation or convection. In turn, that means during the formation of materials, you are able to make them more homogenous on an atomic level. This has huge implications for pharmaceuticals, semiconductors, and biologics. You are able to create materials in space that cannot be produced on Earth.\\\n\\\nIn short, the material production has to be so precise that gravity is too much of a disturbing force and needs to be removed.\n\n\\\n**What are we building right now?**\\\nRight now we are working on our first full-scale re-entry mission, the ENOS mission, which will be launching on a Falcon 9 in a launch window starting in March '26. We will be hosting a pharmaceutical R&D payload on-orbit and fully re-enter and recover the satellite.\\\n\\\nCheck out the following video for more info about ENOS!\\\n\n\n**The Team**\n\nWill and I met at Georgia Tech while we were both pursuing our PhD’s in Aerospace Engineering.

Launching more often and from any rocket.\n\n### **TL;DR:**\n\nModern lunar landers are not designed for the realities of today's launch market, leading to infrequent and expensive flights. Instinct is building a lunar lander that can launch from anywhere, increasing flight cadence and decreasing cost.\n\n\n\n### **The Problem:**\n\nDemand for the Moon is increasing, and modern landers rely on dedicated launches to the Moon that cost upwards of $100M and only fly once or twice a year. This means payload costs of $1.2M/kg and very limited availability of payload slots. Most potential lunar payloads are either stuck on Earth or never leave the concept stage.\n\n### **Our Solution:**\n\nInstinct's lunar lander is small enough to launch as a rideshare to Low Earth Orbit, enabling low-cost, high-cadence missions. From LEO, our lander makes its way to the Moon without the need for refueling or multiple stages, delivering 20kg of payload to the Moon at a cost per kg of less than half that of current providers.\n\n![uploaded image](/media/?type=post&id=103381&key=user_uploads/1741395/a31b9757-ea96-4f67-8e24-a31ef7bf474b)\n\n\nAt its core, our lunar lander relies on custom propulsion and visual navigation systems, which enable our unique architecture and most importantly are designed to keep vehicle mass as low as possible. This reduces launch cost and maximizes performance.\n\n![uploaded image](/media/?type=post&id=103381&key=user_uploads/1741395/6887996a-f7fc-4d07-a5ae-68e548ba6acf)\n\n### **Who We Are:**\n\nOur team brings years of experience working on space missions including NASA's IMAP, ESA's Solar Orbiter, and PhiSat-2.\n\nWe are super passionate about space exploration, and have also experienced firsthand the pains involved in developing lunar missions nowadays.

Our core product automates lengthy, complex, and regulated quality documentation in aerospace manufacturing.\n\n**How We Started**\n\nNick and Matt co-founded their last startup (InspectAR) with Mehul's brother before being acquired by Cadence ($CDNS). I (Mehul) spent the last decade in my family business, where we built PCBs for every advanced system on Earth: rockets, satellites, aircraft, fighter jets, and more. We noticed despite building for innovation, manufacturing operations were antiquated and bogged down with manual processes.\n\nFirst Article Inspection Reports (AS9102s) were creating a bottleneck in quality. Parts would be built and ready to ship, just waiting on paperwork. Our facilities were doing 15 reports a day, 8 hours per report. The worst part? Even if the part was built exactly to spec — if a single typo was found by the customer, the report would get rejected and payment delayed until the report was fixed.\n\n**What We Built**\n\nOur core product automates first article inspection reporting for regulated manufacturing. Quality teams can balloon drawings and automate inspection report generation in minutes, instead of days.\n\n**Our Vision**\n\nToday, over 70 facilities across the US generate almost 1000 reports a month on our platform. This is just the beginning. We'll continue to build for quality, and upstream towards operations, engineering, and sales to empower manufacturers with AI.

But lack of large dishes is not the only thing broken about space communications, so are the design tools. \n\nIndustry standard spreadsheets are painful to build and maintain and error prone, but they can at least get you started. That said, they completely break down once you need to predict how your spacecraft will perform in real world dynamic environments, analyzing multiple variations of a system, or sharing and keeping the design updated across teams.\n\n![uploaded image](/media/?type=post&id=96236&key=user_uploads/222992/5bdf36f9-9f71-4796-9f12-ecbeba37d8c4)\n\nEvery space company eventually starts to build internal tooling to parse 3D antenna patterns and scripts to evaluate link performance over given flight trajectories. This is usually unplanned work done by RF engineers that takes months to get even a rudimentary implementation up and running. This software is very bespoke and often brittle, and makes the tight timelines of early stage companies even tighter.\n\nAcross the industry this work gets duplicated over, and over, and over. \n\n**Enter Cascade Designer**. The pipeline is already built. Start by designing your system in a graphical interface, get your link margin with a single button click. \n\n![uploaded image](/media/?type=post&id=96236&key=user_uploads/222992/7e4a5642-dc70-4093-a7d5-5a2b1802cda3)\n\nNext, analyze entire trajectories with a single API call. \n\n![uploaded image](/media/?type=post&id=96236&key=user_uploads/222992/980c9907-784c-4861-8758-b6341afd2721)\n\nDesigns can be shared with anyone on your team through our interface\n\n![uploaded image](/media/?type=post&id=96236&key=user_uploads/222992/bec0b967-999c-4089-849f-d0c547431498)\n\nWe built this out because the customers of the best ground network need the best design tools, but we didn’t just build this for our ground station customers.

Companies with missions going to the Moon and beyond have to deal with a patchwork of individual dish operators for every mission, each with bespoke hardware, specs, and interfaces. Furthermore, many of these commercial providers are not able to handle the demand and [operational failures also can lead to loss of mission](https://www.astroforge.com/updates-collection/odint-mission-debrief).\n\n![uploaded image](/media/?type=post&id=90423&key=user_uploads/222992/c6aa8968-e567-42e5-8866-866414630f22)\n\n**Comms system design is fraught with peril**\n\nThe spacecraft comms system design is tightly coupled to the available ground network. Engineers spend hundreds of hours poring over datasheets, on the phone with vendors and suppliers, and endless email threads, only to put all this data into a giant spreadsheet to make sense of it. Every iteration requires not only painful attention to detail, but also in-depth esoteric knowledge of how radio frequency systems and channel coding schemes work in order to accurately predict in-flight performance. Simple misunderstandings can lead to catastrophic errors in design and configuration.\n\n![uploaded image](/media/?type=post&id=90423&key=user_uploads/222992/1623d16f-4789-4793-892f-2c7adffc84a7)\n\n**End-to-end comms system validation often doesn’t happen**\n\nFully integrated testing between the spacecraft and ground terminal is typically cost prohibitive. Instead, engineers compare spec sheets and email configurations to the ground operators, and hope it works in flight (spoiler alert: it often doesn’t). It is routine for spacecraft to fly having never done an end-to-end test of their system with ground terminal representative hardware. The whole process is subject to human error from end to end. \n\n**This approach to space communications does not scale**\n\nCommercial space ventures beyond low earth orbit have already pushed existing infrastructure to its breaking point, and demand for deep space comms support is expected to grow exponentially over the next decade. We will not have a spacefaring future for humanity until communications for spacecraft become as easy as signing up for cable internet. \n\n**We are redefining the process, starting with spacecraft design**\n\nBetter comms starts at the beginning, in the early trade study and design phase. We are replacing industry-standard spreadsheets with a modern software tool that lets you see how your system will perform with our ground network in real time.\n\n![uploaded image](/media/?type=post&id=90423&key=user_uploads/222992/4873c5a0-9288-48fe-8d2e-a3a32f3fcad0)\n\n**Test as you fly, fly as you test**\n\nYou don’t rise to the level of your expectations, you fall to the level of your testing. We ship you a “ground station in a box,” identical to hardware we’ve installed at the ground stations you will be using, and provide you with a test plan that you can use to test your entire system end to end, with both the space vehicle and the ground terminal in the loop. \n\n**Launch with confidence**\n\nFly and operate your spacecraft. Use our API to schedule passes on our network, track your spacecraft, stream data, monitor the ground site, and access recordings.\n\n![uploaded image](/media/?type=post&id=90423&key=user_uploads/222992/2b01ca98-b6d7-4f8b-9af5-5b93b0613ef0)\n\n**We are rolling out our preliminary network rapidly**\n\nWe start by partnering with owners of dishes that are currently unused for any other telemetry applications. This allows us to build out the product and acquire customers with a minimal amount of capital. As we build out the network, we will further expand our network by strategically building our own ground stations in key locations. Our first downlink only ground stations are expected to come online in 2025, with more to follow in 2026.\n\n**We are passionate about your mission success**\n\n[Jacob](https://bookface.ycombinator.com/company/30556) and [Arlen](https://bookface.ycombinator.com/user/2222230) have solved many of these exact problems at company level scales in previous roles.

With backgrounds at Tesla and SpaceX, we’re building a platform that finally treats drawings like code—automatically validating every dimension, tolerance, and GD&T symbol against standards so noncompliance is caught instantly.\n\nhttps://youtu.be/SYzqZ4XWmCA\n\n![uploaded image](/media/?type=post&id=93123&key=user_uploads/2642473/a6d6c66e-7e58-4405-b4e2-48c30b354495)\n\n# **The Problem & Why We Built F4**\n\nDrawing literacy is one of the weakest skills across hardware teams. Yet drawings are made every day.\n\nThese aren’t just illustrations—they’re effectively business contracts between designers and manufacturers, defining what’s acceptable in production. Drawings carry the bulk of design intent—fit, form, function, and fabrication—and act as the important source of truth across production, quality, and supply chain.\n\nGD&T standards from ASME and ISO exist to formalize this communication. But they’re dense and confusing. Across major revision years, there are thousands of pages of definitions, edge cases, and revision quirks. Designers are expected to know it all, leads are expected to catch every mistake, and suppliers are expected to interpret drawings flawlessly. One mistake means scrap, delays, or worse.\n\n# **Our Solution**\n\nWhy is something so critical still so manual? Why can’t drawings be validated and interpreted more quickly and robustly —like code? Why can’t hardware dev be more like software dev?\n\nWe’re changing exactly that!\n\nF4 treats drawings like code—they either execute or fail immediately. Our platform checks every dimension, tolerance, and GD&T symbol against standards in real-time, ensuring full compliance before a drawing ever reaches the floor. No more total reliance on manual redlining and reviews.\n\n![uploaded image](/media/?type=post&id=93123&key=user_uploads/2642473/1aa5904c-3086-4722-8838-ffda9c0d7a85)\n\nF4 ensures engineers never release noncompliant drawings—and suppliers never misinterpret them. F4 helps industrial teams eliminate costly scrap, rework, and miscommunication at the root.\n\n# **How It Works**\n\n1. Upload a drawing (dxf…and very soon pdf)\n2. Select GD&T standard of choice (ASME Y14.5 - 1994, 2009, & 2018)\n3. Get instant compliance score graded against a desired GD&T standard using **deterministic logic**\n4. Get recommendation to correct any asset (FCF, FOS, datum, basic, modifier, and/or dimension) of the drawing that is noncompliant with references to ground-truth sources\n5. With a compliant drawing - get standard definition, inspection plan, and tolerance analysis interpretations on any drawing asset of interest\n\n![uploaded image](/media/?type=post&id=93123&key=user_uploads/2642473/accc67da-db20-423d-84b0-7ec4904ad800)\n\n## **Hardware Platform Built by Hardware Engineers!**\n\nI worked at Tesla as a Mechanical Design Engineer and took 6 parts from clean sheet design to production for the CyberCab and SEMI drive system programs. I was also the lead engineer for Tesla’s global drive unit heat exchanger program with +3 million unit annual production volume.\n\nAidan worked at SpaceX as an Avionics Test Engineer, where he designed and owned testing hardware (PCB boards and testing apparatus) for the Raptor 3 Engine - the most advanced rocket engine in the world. \n\nIn college, we led The University of Alabama’s Rocket Team where we achieved the university’s first-ever liquid rocket engine hotfire!

](https://www.linkedin.com/in/tobifischer/)and [Sebastian](https://www.linkedin.com/in/sebafischer/). Cofounders (and brothers!) of [Wardstone](https://www.wardstone.space/).\\\n\\\n**TL;DR:** Wardstone builds satellites for missile defense. We are pursuing an emerging \\~$40B/year space defense market as part of America’s Golden Dome initiative. Tobias studied Mechanical Engineering at Cornell and worked at Astranis. Sebastian studied Aerospace Engineering at MIT and worked at NASA, Lockheed Martin, Amazon, and Cruise. We built and demoed a live ground-based missile intercept during YC.\n\n# **Launch Video**\n\nCheckout the automated missile defense system we built during YC:\n\nhttps://youtu.be/jXABTM9GZ6s\n\n# **About Wardstone**\n\nWardstone builds space-based interceptors: satellites with interceptors designed to kinetically destroy missiles. New space threats, specifically hypersonic missiles, are emerging as existential threats to the United States. Our current missile defense systems were not designed for this new offensive technology. The United States’ Congress has allocated \\~$25B towards developing new on-orbit hypersonic missile defensive missile capabilities over the next 3 years. Follow on build out of this on-orbit defensive layer coined the _Golden Dome_ has been estimated by congress to cost up to $831B over the next 20 years.\\\n\\\nAt Wardstone, we believe that we can build defensive missile capabilities for a fraction of the cost of the offensive hypersonic weapons themselves, and orders of magnitude cheaper than the defensive concepts being proposed/explored by the major defense primes. We will do this with our first product, Hailstorm, that deploys high speed clouds of buckshot to kinetically destroy hypersonic missiles.\n\nOur integrated interceptor-satellite constellation provides global intercept capabilities from space for various missile types beyond hypersonics. \\\n\\\nThe success of Wardstone and the full deployment of the Golden Dome will place the United States in an incredibly strong geopolitical position.\n\nThe full Wardstone constellation with the space based intercept capability in action will look like this:\n\n![uploaded image](/media/?type=post&id=95440&key=user_uploads/2077453/f2a877a7-c23c-438d-8714-5a854930bba2)\n\n# **Our Progress During YC**\n\nDuring YC we had 2 main objectives: 1) build our first missile intercept demo and 2) establish relationships with our main customer: the US Space Force.\\\n\\\n**The Intercept Demo**\\\nWe built a fully automated missile tracking and intercept system that uses infrared computer vision for predicting the future missile position and a high pressure air cannon to deploy an interceptor to destroy a 150+ mph missile.

Microgravity unlocks better pharmaceuticals, purer semiconductors, and flawless optical fibers. The bottleneck was never the science, it was the labor to do it.\n\n\n\n**Advantage of Microgravity**\n\nMicrogravity changes what's physically possible. Proteins crystallize with fewer defects, critical for drug development. Semiconductors and optical fibers form without the flaws that gravity creates. Pharma and tech companies are already investing in orbital research.\n\n**The Problem**\n\nBut astronaut time is expensive, and there's not nearly enough of it. On ISS, NASA estimates crew time at $130K per hour. On commercial stations, it's more than three times that. Crews have to sleep, rotate home, and pick and choose which experiments to run. Most of the work that could happen in space simply doesn't.\n\n**The Solution**\n\nWe're building robotic systems that handle laboratory work: pipetting, sample prep, plate handling, reagent mixing, with the precision and autonomy to operate without crew. The goal is simple: make microgravity research and manufacturing scalable, not bottlenecked by how many people you can put in orbit.\n\nOur team comes from SpaceX, Caltech, and Carnegie Mellon. We've spent our careers on robotics, spacecraft systems, and the intersection of both. We started General Astronautics because the limiting factor in space was never the science, it is the capacity to do it at scale.\n\n**The Ask**\n\nIf you have connections to pharma or biotech companies interested in space-based research, whether protein crystallization, biologics, cell culture, or silicon manufacturing, we'd love an intro.\n\nConnect with us: [founders@generalastro.com](mailto:bram@generalastro.com)\n\nX: \n\nLinkedIn: ", "url": "https://www.ycombinator.com/launches/PY8-general-astronautics-robots-for-space", "votes": 15, "created_at": "2026-02-26T19:57:51.987Z" } ] }, { "id": 31142, "name": "Beyond Reach Labs", "slug": "beyond-reach-labs", "former_names": [], "small_logo_thumb_url": "https://bookface-images.s3.amazonaws.com/small_logos/68e78dbe382d51a7e7c3d02cc8ca43db9513c3d4.png", "website": "https://www.beyondreachlabs.com", "all_locations": "New York City, NY, USA", "long_description": "At Beyond Reach Labs we are building solar panels for Space that grow from the size of a dining table to a football field in orbit.\r\n\r\nMitch and Pele met 13 years ago as freshmen at UPenn studying mechanical engineering.

Space unlocks an entirely new class of products impossible to create on Earth but the infrastructure to manufacture at scale in space and return the products to Earth doesn't exist yet.\n\nWe're Payton and Andrew. We spent 4 years together at Astranis building geostationary communications satellites. We know how to build hardware that survives the extreme environments of space. Now we're building the vehicles to bring it back.\n\n**We just got back from the Mojave Desert** where we tested our first full-scale reentry heat shield, designed to protect a spacecraft returning from orbit at Mach 20+. We built it in an apartment for **100x cheaper than competitors**, held it behind a rocket engine to simulate atmospheric reentry and it worked as designed! \n\n**The Problem: Getting things back from space is harder and more expensive than sending them up.**\n\nCheaper launch costs and new heavy launchers like Starship and New Glenn are driving a boom in space manufacturing. Pharmaceutical, semiconductor, and biotech companies are racing to produce in microgravity. But return is the bottleneck:\n\n\\- NASA pays **2x more** to bring cargo down from the ISS than to send it up\n\n\\- Human-rated vehicles add massive overhead costing **over $100,000/hr** for astronaut time\n\n\\- Return slots from the ISS are limited to a handful of Dragon missions per year, on\n\n  NASA's schedule, not yours\n\n\\- The ISS is aging infrastructure with an uncertain future and no clear successor\n\nAccess to orbit is cheaper than ever. Return is the unsolved problem. That's where we come in.\n\n**What We're Building:**\n\n**Phase 1: Reentry Vehicles (mid-2027 first flight)**\n\nRefurbishable, autonomous reentry vehicles designed for mass manufacturing. Customers manufacture products inside while in orbit. We return them to Earth, swap the heat shield, and fly again. No astronauts, no ISS, no 6-month wait. Dedicated missions on your schedule.\n\n![uploaded image](/media/?type=post&id=99179&key=user_uploads/564908/60dbaefc-95c5-4f64-8d26-0dbffe3404d1)\n\n**Phase 2: Uncrewed Space Stations**\n\nTo scale space manufacturing, you need permanent infrastructure in orbit. Serviced by our reentry vehicles. We're building high-power uncrewed space stations designed from day one for lights-out manufacturing unburdened by human life support, serving as a shared utility grid so payloads can leverage massive power without carrying the mass and complexity of their own high power bus.\n\n![uploaded image](/media/?type=post&id=99179&key=user_uploads/564908/4911d2cd-a89b-496d-b8f3-3c89d3763f3d)\n\nThe ISS proved that manufacturing in microgravity works. But it was built for humans, and everything that rides on it reflects that in their cost, schedule, and complexity. The next generation of space infrastructure doesn't need to. Advancements in autonomy let us build cargo-only vehicles from the ground up: cheaper, faster, and scalable. The space economy needs its own industrial layer and we’re here to build it.\n\n**We'd love to hear from you!** If you're building something that needs microgravity, dealt with reentry or thermal protection systems, or if you just have strong opinions about how space logistics should work - let's talk.

In 2022, Starlink access was suddenly cut to stop a Ukrainian counteroffensive. As a result, nations have realized that a foreign superpower owning your satellites makes you ultimately dependent on their continued permission to access it.\n\nIn Europe, telecoms are warning about the danger of relying on foreign-owned AI and satellite infrastructure:\n\n![uploaded image](/media/?type=post&id=109889&key=user_uploads/689300/9dc3272a-bf85-4710-ad4d-e4592100ca1e)\n\nIn Indonesia, telecoms are lobbying for a Starlink ban:\n\n![uploaded image](/media/?type=post&id=109889&key=user_uploads/689300/5596ba12-4d01-4acd-b11c-8b1e777bb663)\n\nIn India, Starlink rollout has been delayed due to security concerns:\n\n![uploaded image](/media/?type=post&id=109889&key=user_uploads/689300/e4e7cd9a-e67d-42f8-bd8a-c1a78a0f4034)\n\nAnd even nations like Canada are moving off of dependence on American space infrastructure:\n\n![uploaded image](/media/?type=post&id=109889&key=user_uploads/689300/b73fbed9-3742-4105-8a86-de42843dbd1b)\n\nBut even if they don’t trust Starlink, that doesn’t mean they necessarily trust constellations like Qianfan or Guowang that are owned and operated by Chinese state enterprises.\n\nHowever, other alternatives outside of the U.S. and China face years of delay or need millions of dollars just to build a single satellite, which leaves hundreds of millions people still without reliable connectivity. \n\n### **🛰️ Our Solution**\n\nExosat fixes this problem by building thousands of satellites at a tenth of the usual cost.\n\nWe focus entirely on civil and commercial customers outside of the United States or China and fly our satellites in lower orbits versus incumbents like AST and Iridium, enabling us to take advantage of better link budgets, faster latency, and a milder radiation environment.\n\nThese factors let us use global manufacturing hubs or local partners to build our satellites using automotive-grade parts and **zero** ITAR/EAR-controlled supply chains, enabling us to seamlessly launch from other nations to bypass capacity bottlenecks and access equatorial orbits.\n\nAs a result, we can deploy a communications satellite with a 3-5 year lifespan for **\\~$300k instead of $5M** and in days instead of months, enabling us to manufacture and deploy a mega-constellation at near cost-parity to Starlink.\n\n**Our thesis is simple: we’re building a satellite at <10% of the cost to dominate 80% of the market instead of going after everyone.**\n\n### **👋 About Us**\n\nI’m a second-time space founder who previously built Aethero, a company developing satellite edge computers. We scaled to millions of dollars in revenue from defense primes like Blue Origin and Booz Allen Hamilton, won multiple SBIR awards, launched two satellites to orbit, and did radiation research on GPUs with the Aerospace Corporation and AFRL.\n\nI started Exosat and moved to Singapore because I think a future where SpaceX and China monopolize the space economy is a bleak one. I’m willing to go for broke, and put down the deposit for our first launch slot next year with my own money.\n\n### **📈 What have we done?**\n\nSince starting out this summer, we’ve:\n\n* **Booked our first launch** for next April, with early pilots underway to start initial commercial service for satellite IoT no later than the end of 2028.\n* **Added $400M+ in LOIs** from early customers across Southeast Asia, the Middle East, and Central Asia to either lease future network capacity from our dedicated constellation or build and launch their own sovereign networks with our satellites.\n* **Published ITU filings to build an 11,000 satellite constellation** to build the biggest satellite network outside of the United States and China.\n\n![uploaded image](/media/?type=post&id=109889&key=user_uploads/689300/2420ddf1-1da9-4f74-b6ef-15dd51f24eb2)\n\n### **🙏 Our Ask**\n\nIf any of these describe you or your organization, we'd love to talk:\n\n* Network operators interested in space-based capacity\n* National space agencies interested in sovereign space capabilities\n* Industrial users in maritime, energy, mining, logistics, who rely on satellites for tasks such as AIS or remote connectivity\n* OEMs producing satellite-connected devices and gateways\n\n👉 Reach us at [info@exosat.com](mailto:info@exosat.com)\n\n**Fun fact:** We’re the first YC space company to be based in Asia.", "url": "https://www.ycombinator.com/launches/SaP-exosat-building-a-sovereign-starlink", "votes": 29, "created_at": "2026-08-10T20:30:00.246Z" } ] }, { "id": 33111, "name": "Skymerse", "slug": "skymerse", "former_names": [], "small_logo_thumb_url": "https://bookface-images.s3.amazonaws.com/small_logos/dcac201e21fa70f9b3a8a1b827c8fd7759c25920.png", "website": "https://skymerse.com", "all_locations": "San Francisco, CA, USA", "long_description": "Skymerse is building one AI system for airline flight operations: from planning and monitoring in the operations center to real-time support in the cockpit.

I’m a licensed flight dispatcher and have spent 10 years working across flight operations, aviation data, and software.\n\nWe’re building one AI system to automate flight operations - from planning and monitoring in the operations center to real-time support in the cockpit.\n\nOur goal is full automation of the work behind every flight.\n\n\n\n## The problem\n\nAirlines have spent decades digitizing flight operations. The information moved from paper to screens. The work of understanding it did not. A flight exists across many systems. Each system may be good at its own job, but the complete operational picture exists between them.\n\nPilots and operations teams still have to build that picture themselves. They search, compare, and interpret information to plan, monitor, and adapt every flight from schedule to landing.\n\nWhen something changes, they do it again. When responsibility moves from the operations center to the crew, much of the context has to be passed on or rebuilt.\n\nToday, people are the integration layer.\n\n## What Skymerse does\n\nSkymerse builds a live operational model of every flight. When an airline’s schedule flows in, it assembles the operational context for each flight and keeps it current as conditions change.\n\nThat model is the foundation for automation. Skymerse does not stop at displaying information or sending an alert. It understands what a change means for the flight, updates the operation, and carries the required work forward automatically.\n\nSkymerse plans, monitors, and adapts flights from the operations center to the cockpit. Instead of rebuilding context across tools and handoffs, Skymerse manages each flight as one continuous process, from schedule to landing.\n\n## Why I started Skymerse\n\nSkymerse started with [Notamify.com](http://Notamify.com). I built Notamify because I was amazed by how much information pilots and ops teams have to process before every flight - and how much of that work was still done by hand.\n\n![uploaded image](/media/?type=post&id=111421&key=user_uploads/1472269/7e9fe835-e22f-4cb1-92dc-ac0f99a0cce2)\n\nNotamify interprets every single NOTAM into operational impact. It reduces the briefing time from 2 hours to 2 minutes per flight. It now serves airline customers and thousands of pilots and aviation professionals.\n\nAs we built it, the larger problem became clear. Making one source easier interpreted is valuable, but people still have to connect it with the rest of the operation. They still have to work out what it means for their flight and what to do next.\n\nSkymerse is that next step: from helping people understand one part of a flight to automating flight operations e2e.\n\n## Automate your flight operations\n\nWe are onboarding airlines that want to automate their flight operations. If you lead flight operations, dispatch, or an OCC, we want to show you Skymerse on your flights.\n\n[Book a demo](http://skymerse.com/demo) or email [hello@skymerse.com](mailto:hello@skymerse.com).", "url": "https://www.ycombinator.com/launches/Sz7-skymerse-autopilot-for-flight-operations", "votes": 30, "created_at": "2026-08-20T23:00:00.215Z" } ] }, { "id": 33312, "name": "Ethos Space Resources", "slug": "ethos-space-resources", "former_names": [], "small_logo_thumb_url": "https://bookface-images.s3.amazonaws.com/small_logos/26c677c7621160c55e8011d6851971173fe4f8e9.png", "website": "https://ethos-space.com", "all_locations": "Los Angeles, CA, USA", "long_description": "Ethos makes silicon on the Moon to power terawatt scale data centers.
