because the difference between those two mediums is virtually insignificant when we're talking about a 200 pound human jumping up through air with a bit less oxygen in it. the better question is, why is it that on the 1/6th gravity of the moon they were not able to jump any higher? with 1/6th the gravity a 200lb man would be ~30lb and should be capable of crazy feats impossible here on earth
