A so-called space bike which once belonged to the first man to walk on the moon Neil Armstrong. It was due to go under the hammer at Sotheby's Space Exploration auction which coincides with the 48th anniversary of the first moon landing. It's an outer decontamination bag so it was used to protect those samples from any contamination from us and planet earth but also to protect the space craft and planet earth from potential contamination from lunar pathogens. Other artifacts and souvenirs also up for auction this framed photo signed by Buzz Aldrin and a flight plan of the Apollo 13 mission. The space bag is set to fetch millions.
