Mission Requirements
- Extend a 200 g magnetometer at least 1 m from satellite
- Fit inside 10×10×10 cm volume at launch
- Minimize magnetic interference and mechanical complexity
- Focus on simplicity, reliability, and cost
Blue Origin x MIT • Deployable Structures • Structural Analysis
Designed a deployable boom to extend a 200 g magnetometer 1 m from a 10×10×10 cm satellite volume for Blue Origin’s Oasis‑1 concept. The team explored both a passive STEM boom and a carbon‑fiber composite boom.

Used pre‑stressed tape‑measure geometry to deploy without motors. Key advantage: simplicity and gravity‑independent deployment. Key challenge: high pre‑tension and brake control.
Explored carbon fiber laminate boom using Classical Laminate Theory, rule‑of‑mixtures, and FEA. This concept offered higher stiffness potential but increased complexity.
