as the speed of sound is relative to the medium it travels in (for example, it is different on the earth at sea level compared to the top of mt. everest), what would it be at 'sea level' on mars? <br /><br />bear in mind, too, that the air on mars is extremely thin, dry and mostly CO2. <br /><br />furthermore, to create aerodynamic lift, any craft with an aerofoil would need to be accelerated to even higher velocities in this thinner, colder, atmospheric condition for it's surface area to be effective. <br /><br />what would then be the bare minimum velocity to generate this aerodynamic effect, ie, lift or negative lift, given 'x' surface area?
