Question

It has been proposed that we could explore Mars using inflated balloons to hover just above the surface. The buoyancy of the atmosphere would keep the balloon aloft. The density of the Martian atmosphere is 0.0154 kg/m3 (although this varies with temperature). Suppose we construct these balloons of a thin but tough plastic having a density such that each square meter has a mass of 4.70 g . We inflate them with a very light gas whose mass we can neglect.

r=0.916 m

msurface= 0.04955 kg

If on Mars these balloons have five times the radius found in part A, how heavy an instrument package could they carry?
