NASA Flight Director Gene Kranz was on duty when Apollo 11's lunar module landed on the moon and still makes public appearances at the age of 84. Armstrong also unveiled a plaque on the leg of the Lunar Module which read, "Here men from the planet Earth first set foot upon the Moon, July 1969 A.D. We came in peace for all mankind".
AM 760's Mark Larson chatted with Colonel Buzz Aldrin to reflect on such a monumental observance, and details on the possibility of the astronauts not coming home.
Items to be auctioned include artifacts and keepsakes that range from the cap that Armstrong wore as a Boy Scout to materials from the 1903 Wright Flyer, the world's first powered airplane that the astronaut brought with him to the moon in July 1969.
Other items that the astronaut took with him to the moon include a USA flag, the largest size typically flown during Apollo missions, a United Nations flag, various state flags, and some Robbins Medallions.
And now, in a series of auctions starting November 1 and 2, his collection will be offered for sale.
