A bag Neil Armstrong used to collect the first ever samples of the moon, which was once almost thrown out with the trash, sold at an auction in New York on Thursday for 1.8 million US dollars, Sotheby's said. The outer decontamination bag, which was flown to the moon on Apollo 11 and still carries traces of moon dust and small rocks, was sold on the 48th anniversary of the first moon landing in 1969.
