Exactly- IIRC the problem with martian atmosphere is that its too thick to ignore (hello Mars Climate Orbiter) yet not thick enough for landing havy craft with parashutes or aero surfaces only. See the crazy sky crane system the latest Mars rovers use to work around it.
That they (at least on paper) have a solution for this problem good enough for a 60 metrr craft weighting 100+ tons makes the whole thing even mord remarkable! :)
