I wonder if the lower gravity completely compensates for the reduced thrust due to the thin atmosphere...

I am, somehow, less interested in the weight and convolutions of Einstein’s brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops. - Stephen J. Gould
