MRO has shifted from the cruise phase to Approach phase. Apparently, the trajectory is so good that TCM-3 was cancelled. This is good news for the prospects for a long life for MRO supporting future missions. TCM-4 is on Feb 28, and MOI on March 10. Only 5 weeks away!

Propellent: It is monopropellent. ONLY one : HYDRAZINE. It is a fuel. It does not need oxygen as an oxidizer to ignite. What is the catalyst material that causes the hydrazine to be fueled. Electrical ignition? Hydrazine explodes on contact with many common metal oxides. Found this: "Most hydrazine thrusters use a catalyst bed made from iridium impregnated alumina (Al2O3) pellets 1.5 to 3 mm in diameter." |
