RockeTree
To Be Released!
We’re working diligently to ensure the content and user interface are just right for the best learning experience.
RockeTree - Your Gateway to Aerospace Engineering
At jm_space, we've always been driven by a passion for inspiring the next generation of aerospace engineers and STEM enthusiasts.
Since our founding in 2019, we've shared our journey through model rocketry to ignite curiosity and foster a love for aerospace.
Now, we’re taking our mission to the next level with RockeTree—a unique learning platform designed to make model rocketry and aerospace education more accessible to everyone.
Why RockeTree?
Many of our viewers frequently ask us how they can develop their own model rockets. Until now, finding comprehensive and approachable resources for this has been challenging. RockeTree bridges that gap by providing a structured, user-friendly approach to learning aerospace engineering.
The Tree Structure: Picture a tree with branches representing various aspects of aerospace engineering. Each branch delves into a distinct topic, such as software development, electronics, flight mechanics, aerodynamics, and rocket flight.
Customized Learning Paths: As you progress through a branch, you unlock new topics tailored to your interests. Whether you’re captivated by flight computers or prefer to skip electronics and focus on other areas, RockeTree allows you to chart your own learning journey. The choice is entirely yours!
WebApp
To bring this learning transformation to life, we’ve developed our own WebApp.
Explore the Tree Structure: Within the WebApp, you can navigate through the tree structure, unlocking new topics, advancing in areas of interest, and mastering any skill you choose.
Engaging Learning Materials: Each topic features a blend of videos and text lectures to teach you the essential concepts, paired with interactive activities to reinforce your understanding.
Gamified Experience: To make your learning journey more engaging, you earn experience points by completing activities and progress through levels, from intern to mission control specialist.
Community: RockeTree also emphasizes building a community of like-minded individuals. Join our Discord server to exchange project ideas, troubleshoot challenges, and showcase your results with others.
Content
Creating content to guide you through model rocket development is a significant endeavor. Despite our full-time efforts from June to August 2024, we will only be able to offer a limited portion of the learning platform at launch due to the extensive amount of work involved in content creation.
Initially Available Path: The first available path will be the Electronics Path, where you’ll learn to develop your own flight computer.
Future Expansion: We plan to expand our content over the coming years to include everything from CAD design of rockets to flight computer development, programming, and launch procedures. As you progress and as our user base grows, we’ll continually add new resources to further enhance your aerospace education journey. Stay tuned for ongoing updates and additions!
Electronics Path
The first path available within RockeTree is the Electronics Path.
Here, you'll start with the fundamentals of electronics, including key concepts such as electrons, current, and voltage. You'll then progress through the study of various components and how to arrange them to build circuits for flight computers. By the end of this path, you'll have the knowledge and skills to design and order your own flight computer.
Currently, the Electronics Path includes over 5 hours of video content across 39 videos.
Here’s what the course structure will look like:
