Quoted By:
The public was told that modifications were made to the space suits by the time of the later Apollo missions.
In the july 1971 issue of national geographic, in an article entitled “the climb up cone crater” Alice J. Hall stated quote, “Apollo 15's lunar module will be able to
stay on the moon 67 hours twice as long as Antare’s did. Improved suits will allow greater mobility as the space men go about their chores”.
Now you can compare the sizes of the Apollo 11 suits with the Apollo 16 suits
and see that the later suits were less bulky in appearance therefore astronauts in the apollo 16 mission should not have had any trouble on the moon if one's sixth gravity conditions existed.
Hills should have been climbed with leaping bounds and great distances should have been covered in short time periods by the astronauts with their
combined total body weight equipment and suit weight should have weighed no more than 62 pounds
It should have been as if they had been able to recapture of their youth, but that's not what we saw.
Before the ill-fated Apollo 13 mission which never made a lunar landing, astronauts including Hayes, practiced a traverse in Verde valley within Prescott national forest Arizona.
This was to give them the experience they would need to reach a cone crater on a ridge about 400 feet higher than the proposed landing site elevation.
Practices in arizona would be totally useless if one-sixth gravity were to be encountered on the moon.
