Sometime in the 1970s, the US astronaut gave the vial of moon dust along with a handwritten note to Murray’s little girl when she was 10.
Cicco has now sued NASA because the space agency has “a history of seizing suspected lunar material from private citizens”, her attorney was quoted as saying.
The vial of dust that Cicco has, was analysed by scientists who said it was “likely” a sample of the lunar surface.
Cicco’s lawsuit cited another case where NASA seized lunar mementoes from an elderly California woman which was gifted to her by her late husband and an Apollo programme engineer.
Reacting to the lawsuit, a NASA spokesperson said it would be “inappropriate” for the space agency to comment.
When Armstrong stepped onto the lunar surface, he said: “That’s one small step for man, one giant leap for mankind.”
