I believe that content produced by NASA is largely available in the public domain, although there are restrictions concerning the use of images featuring staff members and the NASA emblem. This means there should be no geographical limitations on their distribution, which would likely apply to this service as well. I remember joking with my friends in Japan about the contrast with JAXA, who conspicuously mark their 'Earthrise' footage from the Moon with "(C)JAXA/NHK," while NASA's equivalent content is freely shared with the global community.
