The Navajo Nation had previously expressed concern about human remains being sent to the Moon in 1998 after the NASA Lunar Prospector mission.
Buu Nygren, president of the Navajo Nation, requested that NASA delay the launch because memorial payloads on Peregrine are viewed by the Navajo Nation as desecration and he cited an agreement after the 1998 Lunar Prospector mission that carried Eugene Shoemaker’s ashes.
