Scientific paper

An evaluation is conducted of the use of novel, metallized-propellant propulsion systems to reduce launch masses for manned Mars missions on the basis of density and I(sp) enhancements. The use of metallized propellants leads to a 3.3 percent LEO mass saving which represents 38,000 kg less than O2/H2 propulsion. Attention is given to the possibility of using space-storable propellants for the Mars excursion vehicle, as an alternative to the storing of cryogenic H2 on Mars, albeit at the cost of lower I(sp).
