Apollo 11 lunar module landing sequence
Apollo 11 lunar module landing sequence is a document which provided Neil Armstrong, Michael Collins and Buzz Aldrin with step by step instructions as they guided the Eagle landing craft onto the lunar surface in July 1969 during the Apollo 11 mission. The document lists events and entry commands that enabled the Lunar Module Eagle to travel from lunar orbit and touch down on the Moon’s surface.
The first sheets, PGNS-43/44 show the P63 Braking Phase Program which started the craft’s descent to the moon. The PGNS-43 page shows the configurations for the flight computer for the P63 operations. The final steps of the P63 program are listed on the PGNS-44 sheet.
The page PGNS-45 details the Approach Phase Program. The sheets PGNS-46 and PGNS-47 document the P66 or Landing Phase Program which took place about 500 feet above the surface of the moon.
Page PGNS-48 detailed abort procedures, which were not needed during the mission.
The Apollo 11 Lunar Module landing sequence was sold by Bonhams in July 2009 for $152,000. The document came with a typed letter signed by Buzz Aldrin. The letter explains the documents and discusses what the astronauts were doing at the times that certain notes were made. Each page of the document was signed by Buzz Aldrin, which may have significantly contributed to the value of the item.
