About

Hi, I'm Manuel

In 2020 I set out to learn everything I needed to build a spaceworthy CubeSat that could actually be launched and do something useful in orbit – without any technical training.

In 2024 I started my YouTube channel to document my progress and share what I learn with other space enthusiasts.

In 2025, the first suborbital flight test took place. Development kits based on the lessons learned during that flight are planned for Q4 2026.
