Peroxide Cold Gas Thruster

Peroxide cold gas thruster was a proof-of-concept method for achieving hydrogen peroxide decomposition for the hybrid thrusters. A 50% hydrogen peroxide solution was used with solid potassium permanganate, producing gaseous oxygen and steam (2 KMnO₄ (aq) + 3 H₂O₂ (aq) → 3 O₂ (g) + 2 MnO₂ (s) + 2 KOH (aq) + 2 H₂O (l)).

Test firing was successful, with the prototype successfully completing two testing runs with minimal amounts of H₂O₂ leakage.
