When Neil Armstrong became the first man to walk on the moon, he captured the attention and admiration of millions of people around the world. Neil Armstrong, Edwin "Buzz" Aldrin, and Michael Collins were in orbit around the Moon, the only natural satellite of the Earth.
49 years ago, on July 20 1969, Neil Armstrong took one small step on the moon.
As the United States inches closer to the 50th anniversary of the first moon landing, NASA's effort to resume space exploration and settle on the uninhabited planet may actually become a reality, according to an Apollo 17 astronaut.
Also on sale are the sterling silver Apollo 11 medallions - and a rare gold one - struck by the Robbins Company of Attleboro, Massachusetts, and paid for by the astronauts themselves.
Especially valuable lot will be a gold coin from the collection of astronaut.
Among the more personal items to be auctioned are a Purdue University centennial flag from Armstrong's alma mater that traveled on Apollo 11 and his Boy Scout cap. "There will be items that make you think, items that make you laugh and items that make you scratch your head", the astronaut's son Mark Armstrong said.
"I think the addition that the museum is putting in place will give them a chance to reach out to more kids, and bring them in, and really teach them about science and technology, engineering and math", Armstrong said.
"He did save all the items, so he obviously felt they were worth saving", he pointed out.
"There will be flown items, autographed items and items of historical significance", his son Mark said.
Dallas-based Heritage Auctions will handle the auctions.
The two have collaborated with a firm to document the artifacts' authenticity and provenance.
Bids can be taken online, by phone or in person.
