  • The author shares their first blog post about a failed two-stage model rocket launch named Venessa.
  • The rocket lifted only a few meters before flopping over, leading to laughter and learning.
  • The goal was to design a rocket that could separate mid-flight, not to achieve high performance.
  • Venessa was built as a learning prototype with simplicity and intentional mistakes in mind.
  • Propulsion used metal casings and KNDX fuel for reliability, moving away from PVC.
  • The structure was made from repurposed paper and 3D-printed parts for cost and learning efficiency.
  • Avionics focused on active stage separation using real-time sensor data and redundant flight computers.
  • Recovery involved a spring-loaded parachute ejection system for the second stage only.
  • The first stage was allowed to fall ballistically without a recovery system.
