The mass of the Mars is about 0.11 the mass of the earth, its radius is 0.53 that of the earth, and the acceleration due to gravity at the earth's surface is 9.80 {\rm m}/{\rm s}^{2}.

g = ľ/r^2 gravity on the surface of Mars
ľ = the gravitational constant of Mars
= GM where G = the universal gravitational constant and M = the planet mass
r = the radius of Mars = .53(6378)1000
= 3,380,340m

G = 6.67259x10^-11
M = .11(5.97424x10^24) = 6.571664x10^23

Therefore, the Martian surface gravity = ~3.83m/sec^2.
