Вы читали про табличку?



Что меня поразило оказывается для этой таблички специальная крышечка(открывалась только на луне)  для того , чтобы в случае  если бы модуль хряпнулся, среди обломков не валялась бы табличка, что типа мол "тут ступала нога человека  ".
После этого меня не удивляет, что у них шаттл два раза грохнулся и 14 человек трупов.

WE CAME IN PEACE FOR ALL MANKIND
The plaque is made of #304 stainless steel measuring nine by seven and five-eighths inches and one-sixteenth inch thick. It weighs approximately one pound and thirteen and seven-eighths ounces. The finish has the appearance of brushed chrome and the world map, message, and signatures are in black epoxy which fills the etched inscriptions. To fit properly around but not touching the landing gear strut and to allow room for the insulation material which covers much of the lunar module, the plaque was bent around a four-inch radius. Covering the plaque during flight is a thin sheet of stainless steel which was removed by Armstrong during EVA activities on the Moon. The plaque was made at NASA's Manned Spacecraft Center.

This also reduced the amount of equipment that had to carried inside the already crowded vehicle. It was estimated, however, that the LM ladder would be heated to 250 degrees Farenheit by the descent engines as they fired during the descent staging phase of the landing. The ladder would experience temperatures up to 2,000 degrees Farenheit during the 13 seconds of the touchdown phase. Tests run on the flag determined that it would withstand temperatures of only up to 300 degrees Farenheit . These conditions made it necessary to design a protective shroud for the flagassembly.
