Our fascination with space exploration has only increased since the space program slowed to a halt. To coincide with the 48th anniversary of the Apollo 11 landing, this collection of artifacts will be available for auction. Items include flown mission artifacts, items from astronauts and cosmonauts personal collections, and beautiful space photography. One of the highlights of the lot is the lunar sample return bag containing remnants of lunar dust used by Neil Armstrong on the Apollo 11 mission that was mistakenly discarded before turning up in a private collection two years ago. The auction starts this week and is the first space exploration lot from Sotheby's since the successful Russian Space History sales in the 1990s.
