'For aluminum and magnesium fuels, they would be in the form of a powder as their melting temperatures are too high. They could be injected into the combustion chamber with an inert carrier gas. We have built a rocket engine using carbon dioxide and magnesium powder for use on Mars that blows the magnesium powder via nitrogen gas into the engine's combustion chamber. This approach could also be used with magnesium or aluminum powder for a LOX-aluminum or LOX-magnesium rocket engine. An additional option available with aluminum is to suspend the aluminum powder in gelled LOX to form a monopropellant. This option is not available for magnesium as it is shock sensitive in LOX and will detonate.' 'Magnesium has the next highest specific impulse and combines high specific impulse, no toxicity, and good reactivity in carbon dioxide. According to data from the Viking Lander, magnesium oxide has been found to make up between 8.3 and 8.6% of the Martian regolith.' (This one is particulary interesting..)

I suppose the question is, how to get the Mg out of the soil... Bob Shaw -------------------- Remember: Time Flies like the wind - but Fruit Flies like bananas!

I have some ideas...Probably not executable...But what a grand finale that would be for our beloved rover...Or not...I'm working on the idea... -------------------- "Ride, boldly ride," The shade replied, "If you seek for Eldorado!"

One of the requisits to blow up the magnesium material is the fire. However, MER has no a match with her! No magnificent lens with her to concentrate the sun rays into one point!, she has all warm heaters but not enough red hot to ignite a magnesium!!, What else! Rodolfo
