NASA returns bag of moon dust to woman after year-long legal battle

CHICAGO, Illinois (WGN) -- After a year long court fight, NASA has returned a bag of moon dust to a woman from the Northwest suburbs.

Back in 2015, Nancy Lee Carlson purchased the bag for $995. She bought it in a mix-up during an online government auction. The bag was used to store moon rocks collected by Apollo 11 astronauts.

Carlson said she has been getting hundreds of email every day from people who want to see the rare treasure.
