"The book was flown aboard the Eagle and was located precisely between Commander Armstrong and Lunar Module Pilot Aldrin as they made the historic landing, amidst alarms ringing and with only about 25 seconds of fuel remaining at landing," the news release said. It includes the Eagle's coordinates in the Sea of Tranquility that were written by Aldrin within moments of landing, being the first writing by a human being on another celestial body. Additionally, there are nearly 150 completion checkmarks and other annotations and made in real-time by Aldrin and Armstrong."
