    "long_description": "Relativity is building humanity’s multiplanetary future. We invented a new approach to design, build, and fly our own rockets, starting with Terran 1 – the world’s first entirely 3D printed rocket, and Terran R, our next generation medium-heavy lift reusable launch vehicle.\r\n \r\nAs a vertically integrated technology platform, Relativity is at the forefront of an inevitable shift toward software-defined manufacturing. By fusing 3D printing, artificial intelligence, and autonomous robotics, we are pioneering the factory of the future. Disrupting 60 years of aerospace, Relativity offers a radically simplified supply chain, building a rocket with fewer parts and faster iteration.\r\n \r\nWe believe in a future where interplanetary life fundamentally expands the possibilities for human experience. Our long-term vision is to upgrade humanity’s industrial base on Earth and on Mars.",

        "body": "### **TL;DR**\n\n[Elodin](https://www.elodin.systems) helps aerospace engineers rapidly design, test, and simulate control systems. For example, an engineer could use our Python physics toolkit, which automatically optimizes physics computations for GPU computing, to test a new satellite control system in minutes instead of hours.\n\n---\n\nHello everyone! We’re [Dan](https://linkedin.com/in/x46085), [Sascha](https://linkedin.com/in/sascha-wise), [Andrei](https://linkedin.com/in/andrei-khvalko), [Tom](https://linkedin.com/in/tomgurka), and [Akhil](https://www.linkedin.com/in/akhil-velagapudi/) from [Elodin](https://bookface.ycombinator.com/company/29381). \n\nDrawing experience from roles at AstroForge, Google, Salesforce, Spatial, and several startups. We discovered that the rapid iteration in cloud software was missing in the field of aerospace, so we were compelled to make the development experience better.\n\n---\n\n### **Problem**\n\nIf you want to build an autonomous drone today, you've only got a few options when it comes to testing.\n\n* You can write your control system, flash it to your flight computer, launch the drone, and watch it crash over and over again. \n* You can agonize over setting up a complex simulation using MATLAB, Gazebo, or something homegrown.\n\nThose choices are time-consuming, complex, and costly.\n\nNow, imagine you are building a satellite or an eVTOL aircraft; you have no choice but to set up a complicated simulation.\n\n---\n\n### **Solution**\n\nHow does Elodin prevent this complexity?\\\n**We don’t; we just do it for you.**\n\n![uploaded image](/media/?type=post&id=77547&key=user_uploads/1618322/9f285018-486c-4602-adb3-43297bf75961)\n\nCongrats! You can now simulate your drone's control system easily, but that's not enough. What if a massive windstorm comes around? What if the neighborhood dog decides to take a bite out of one of the propellers? You need to test your control system for any situation you can imagine.\n\n**Enter** - [Monte Carlo Testing](https://aws.amazon.com/what-is/monte-carlo-simulation/#:\\~:text=The%20Monte%20Carlo%20simulation%20is,on%20a%20choice%20of%20action.)\n\nMonte Carlo testing is when you run a simulation multiple times with randomized initial conditions. For example, you could run your simulation with randomized wind speeds.\n\nElodin makes running Monte Carlo simulations seamless, through our cloud platform. We let you run 100,000s of simultaneous simulations right from the comfort of your laptop. \n\nOur dream is that you run a full Monte Carlo test of your control system every time you push code to GitHub. Historically, this would be very costly and difficult to achieve.\n\n---\n\n### **What Elodin is**\n\n🐍 **Python physics library** - A toolkit for building custom physics engines using the GPU, imagine Tensorflow, but for Physics\n\n🎲 **Monte Carlo Cloud Runner** - A cloud runner that enables you to run your simulation in a scalable Monte Carlo fashion\n\n🌎 **3D Viewer** -  A live-reloading 3d viewer to share, inspect, and analyze your simulations\n\n![uploaded image](/media/?type=post&id=77547&key=user_uploads/1618322/d2e5c348-a7f8-47c4-8522-1025a8d966dc)\n\n**Try out our Alpha!** We have an early alpha sandbox prototype that showcases the real-time editing experience of Elodin but does not include our customizable physics engine or Monte Carlo support.\n\n![uploaded image](/media/?type=post&id=77547&key=user_uploads/1618322/effd2707-d83b-4dc4-9c1f-deea7f65fb74)\n\n---\n\n### **Our Asks**\n\n**Reach Out:** If you work with drones, satellites, or anything else with a control system, [schedule a call with our CEO, Dan](https://calendly.com/dan-elodin/30min), to discover how Elodin can streamline your design and testing processes\n\n**Share Your Insights:** We value your perspective! If you have any feedback or suggestions, we'd love to hear from you. Your insights are crucial to shaping the future of Elodin.\n\n**Connect Us:** Even if Elodin is not the perfect fit for your needs, you may know someone who could benefit from our platform. If you have connections in aerospace or related industries, we'd greatly appreciate sharing our website/demo with them or even better a direct introduction to [founders@elodin.systems](mailto:founders@elodin.systems)",

        "tagline": "Introducing New Space Defense Capabilities for America's Golden Dome",
        "body": "# **Introduction**\n\nHi YC,\\\n\\\nWe are [Tobias ](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. Our system provided repeatable behavior, could adapt to different missile speeds, and destroyed a total of 3 missiles. Checkout he video above for the entire story and insights into our system.

We are receiving letters of support for an Air Force $3MM Space Based Interceptor SBIR grant and are receiving inbound requests for additional use cases of our technology (Ground to Air, Space to Ground).\\\n\\\nWe have also engaged with five satellite bus and sounding rocket providers to integrate our Space Based Interceptors for our Series A demo milestone.\\\n\\\nIf Space Defense Technology resonates with you, please reach out: [founders@wardstone.space](mailto:founders@wardstone.space).\n\n![uploaded image](/media/?type=post&id=95440&key=user_uploads/2077453/129abf15-7925-4374-9279-d48e58da1fa2)\n\n---",
