Attn: 'über' space geeks...live play-by-play of a Mars probe entering orbit

Oh...so did your buddy come up with the catalyst heaters or did he come up with a solution to their portential problem (i.e. burning up)?

So the hydrazine...is it something that reacts with something else (with the aid of the catalyst) to produce combustion products that jet out the nozzle or is it just heated so that it will vaporize and thus jet out the nozzle?
