Golf on the Moon (1971)

posted Friday, 6 February 2015

6 February 1971: Astronaut Alan Shepard uses a 6-iron to hit a golf ball into a lunar crater in a lighthearted moment during the Apollo 14 mission. This was the first real mission devoted to science on the moon. Apollo 11 and 12 were more about getting to the moon and back. Apollo 13 should have been the science mission, but wasn’t as we all know know.

A briefcase sized piece of insulating foam broke off the external fuel tank during launch and struck the leading edge of the left wing at 3000 km/h. Impact damage to the thermal protection system 17 days earlier allowed hot gases to penetrate and destroy the internal wing structure during reentry.
