Charlie Duke Family Photo
The Charlie Duke family photo, left on the Moon during the Apollo 16 mission, survived the extreme temperatures due to its placement in a protective container and the Moon's lack of atmosphere, which prevents thermal conduction and convection.
What about contact with the dust.
Moon Dust and the Charlie Duke Family Photo
The Charlie Duke family photo was also protected from the abrasive and corrosive lunar dust, which can be harmful to many materials, by being stored in a protective container or pouch. This prevented direct contact with the dust, allowing the photo to remain intact.
