As a photo produced by a federal agency, NASA's image is not copyrighted. However, NASA policy outlines "strict laws and regulations", including that "NASA is not approving any merchandising applications involving Non-Fungible Tokens (NFTs), as they are not consistent with the categories of products the agency is approved to merchandise... NASA does not wish for its images to be used in connection with NFTs."
The NFTs don't seem to be exactly flying off the shelves. The collection contains 500 copies, and according to the website, only 55 have been sold in the week following the project's release, garnering Mrs. Trump $4,125.
