Auction: Apollo 11 lunar landing manual that flew to the moon and back

The Apollo 11 Lunar Module Timeline Book was a key onboard reference for the heroic astronauts who made the first moon landing on July 20, 1969. Fifty years later, it'll go up for auction at Christies this summer as part of their sale "One Giant Leap: Celebrating Space Exploration 50 Years after Apollo 11." It's expected to fetch between $7 and $9 million. And yes, it really should be in the Smithsonian. According to Reuters, it's being sold someone who purchased it from astronaut Buzz Aldrin. From Christies:

Aldrin had written Eagle’s coordinates in the Sea of Tranquility on page 10 of the book — the first writing by a human being on a celestial body other than Earth....

The Timeline Book narrates the entire Eagle voyage from inspection, undocking, lunar surface descent and ascent, to the rendezvous with Michael Collins aboard the Command Module in lunar orbit. The book contains nearly 150 annotations and completion checkmarks made in real-time by Aldrin and Armstrong. Traces of what appears to be lunar dust are on the transfer list pages that detail the movement of lunar rock samples and equipment from Eagle to Columbia.
