Now, though, they have deteriorated even more thanks to the Moon’s lack of atmosphere to absorb sunlight.
Paul Spudis, who sadly passed away in August 2018, enjoyed a lifetime of work at the space agency.
He said in 2011: “Over the course of the Apollo programme, our astronauts deployed six American flags on the moon.
“For 40-odd years, the flags have been exposed to the full fury of the moon’s environment – alternating 14 days of searing sunlight and 100C heat with 14 days of numbing-cold -150C complete darkness.
“But even more damaging is the intense ultraviolet (UV) radiation from the pure unfiltered sunlight on the cloth from which the Apollo flags were made.
