I'm fairly sure that the Pathfinder/MER airbag systems would weigh in at several times the total mass of the entire Beagle 2 package. All up - Beagle 2 was about 60kg. The airbags are several hundred including gas generators I believe.

        Yeah, the failure of MPL could have been avoided if they used an entirely different landing system. - Robert Clark - 5/23/2004 9:12:10 PM
