アポロ司令・機械船
As the Moon had no atmosphere that would allow a flag to fly on a traditional flagstaff, NASA had originally planned only to imprint a flag on the lower section of the Apollo Lunar Module, which would be left behind on the Moon as the astronauts returned to the Apollo Command/Service Module to journey back to Earth. Kinzler suggested the Lunar Flag Assembly (LFA), a telescoping pole with a horizontal crossbar that would fit inside a hemmed pocket at the top of the flag, making it visible, as if extended in a strong wind. (He credited the idea to having seen his mother hang curtains in a similar fashion during his childhood.)
