What are some of the problems that needed to be overcome in order for nasa to be able to land men on the moon and return them safely?

i am sure that it is true i got this qu before.

the part i "agree with' is " it should not matter what color their skin is or what their cultural beliefs are." but for the main part i agree with it all or if cause now and days there are some people don't get the job cause there skin color and there beliefs and some times they don't even get the same repest as white people. we are all equal.
