working on my passion rocket project. The #Milcomeda 01 Rocket Progress! 🚀 Hey everyone! I have an exciting update to share on my journey into rocketry. A few months ago, I posted about designing and prototyping components for my first rocket project, dubbed "Milcomeda 01." Well, the time has finally come to turn those prototypes into the real deal! This week, I rolled up my sleeves and dove headfirst into the physical construction phase. I've started crafting some parts of the rocket. And the rocket will have a body tube, rocket engine, and nose cone that will form the core of Milcomeda 01. Now, I know some of you might be wondering about advanced features like flight computers, thrust vector control systems, and recovery mechanisms. As much as I'd love to go all-out on the first build, the reality is that budgets are tight for this passion project of mine. So for Milcomeda 01, I'm keeping things relatively simple and focusing on nailing the fundamentals. But don't worry, this is just the start of my rocketry adventures! Once I've conquered this initial milestone, I've got grand plans for Milcomeda 02 and future iterations. We're talking advanced avionics, guidance systems, you name it. You have to walk before you can run into the stratosphere, right? This crazy dream of mine is slow, but I am sure it will become a reality. and I can't wait to share the journey with you all. More updates are on the way as Milcomeda 01 inches closer to its maiden launch. Stay tuned, and get ready for liftoff! #RocketScience #Milcomeda01 Natnael

Stoke Space (YC W21) has successfully completed the first hotfire test for its new full-flow, staged-combustion (FFSC) rocket engine. During the test, the engine successfully ramped to its target starting power level, going from rest to producing the equivalent of 350,000 Hp in less than one second, before holding the power level and shutting down. The engine is designed to produce over 100,000 pounds of thrust at full power. The engine will power the first stage of Nova, the company’s fully reusable medium-lift launch vehicle. Reaching this technical milestone represents a major leap forward for Stoke, as the company is on track to deliver the most robust, fully, and rapidly reusable medium-lift rocket in the world. The technology will enable Stoke’s reusable vehicle to perform missions to and from a wide variety of orbital destinations while still operating with the conservative margins needed for a long service life. Notably, Stoke’s team designed and manufactured this first-stage engine in just 18 months. The achievement follows Stoke’s successful vertical takeoff and vertical landing (VTVL) developmental test flight of its reusable second stage in September 2023. Over the remainder of 2024, Stoke expects to mature its engine and vehicle design while scaling operations for orbital launch. Read more: https://lnkd.in/g9buWvP5

5.000 tons of mass. 120m tall 9m in diameter 33 + 6 rocket engines working with 300bar Big enough to transport up to 100 (!) people When full reusability is achieved the first time, space business cost decreases by 100:1. It’s physics, but for me it feels like alien technology It’s a incredible team performance. Lift off is at 33:50. 😎👍🤸♂️ #inspiration #humanity #perspectives #future https://lnkd.in/eviTWV5f

🚀 Exciting news in the space industry! Perspective Space, a Canadian startup, has emerged from stealth with innovative plans to enhance space weather predictions. This is a game-changer for rocket launch providers, satellite operators, and aviation companies that rely on accurate info about solar flares and geomagnetic storms. 🌌 Currently, these vital predictions are mainly provided by governments using outdated modeling techniques. Perspective Space aims to revolutionize this field with more accurate and advanced models. Stay tuned for more updates as they take space weather forecasting to new heights! #SpaceTech #Innovation #SpaceWeather

This is the story of meeting an engineering legend Dick Rutan whose airplane just landed 🛬. RIP 🙏 Dick, most well known for the first non-stop, unrefueled flight around the world (with Jeana Yeager), pioneering carbon fibers use in aircraft, unique aircraft design including use of the canard and the Stratolaunch (along with Burt Rutan). At the Mojave Air and Space Port April 13, 2019, right after Stratolaunch (worlds largest aircraft) completed the first successful test flight. Sitting in a normally sleepy airport cafe busting with "aviation nerds" who just witnessed such an achievement drinking 2-day old grindy coffee, avgas and dust in the air, I couldn't help but think, when we get to Mars aboard an ultra advanced spaceship, the coffee is going to stink. We got to ask Dick a few questions (paraphrased): - Me "If you had to start now, what would you work on?" - Dick "I have a son studying physics, and there's something wrong with the theory of gravity, I don't like the inconsistencies" - Me "Ok, so trying to redefine the fundamental understanding of physics. If you were to work on something else, what would it be?" - Dick "I also don't like the big bang theory, something doesn't sit right with the measurements and explanation" - Me "Ok, so if you were to start it all over again now, you'd try to redefine a fundamental law of physics, or the origins of the universe" - Dick "Yeah, those are worthwhile projects" Thank you for unbashfully questioning the world and trying to advance our knowledge, understanding, and capabilities. https://lnkd.in/g9CQX2iv

Introducing Leapfrogger: The First Hop Towards Reusability! We are unveiling the design of Leapfrogger, a major milestone in SpanTrik ’s journey toward revolutionizing space access. Leapfrogger is our first Vertical Takeoff and Landing (VTVL) vehicle, designed to develop and demonstrate the capability to launch and land rockets—a critical step in building reusability technology. This is not just another test vehicle; Leapfrogger is the foundation for SpanTrik ’s ambitious vision of developing Raven, our upcoming orbital-class reusable rocket. Through this project, we aim to master the hardware, systems, and prototypes that will eventually power us into orbit. With Leapfrogger, we’re taking our first leap toward making space more accessible, sustainable, and reusable. Follow our journey as we push the boundaries of what’s possible in rocket technology. The sky is no longer the limit—it’s just the beginning. #Spantrik #Leapfrogger #Raven #RocketScience #SpaceInnovation #ReusableRockets #VTVL

QUUB has come such a long way! Look at all the cool things we have done over the years. We have many more memories (and satellites) to make! #RocketScience #SpaceTech #EarthObservation #quubsolutions #quubspace #quub

Ariane 5 Rocket catastrophe with more than 290 Millions Dollars losses, reminds us: Don't just test your software. Test it incredibely well. Nowadays, add the power of AI to support you in finding potential failures. The failure of the Ariane 5 rocket in 1996, which exploded just 37 seconds after launch, highlights the critical importance of thorough software testing. A simple software bug, caused by the incorrect handling of a data conversion error, resulted in the loss of more than $290 million spacecraft. This disaster underscores how small coding issues can lead to catastrophic failures when software isn't rigorously tested. Testing ensures that even minor flaws are detected before they escalate in high-stakes systems like aerospace. The Ariane 5 incident is a stark reminder that testing is not just a phase, but a fundamental safeguard in software development.
