The Navajo Nation, America's largest Indigenous tribe, has raised concerns over the presence of human cremated remains on the lander vehicle, calling the mission a "desecration" of the Moon which holds a sacred place in their culture. On Jan 8, Pittsburgh-based lander is set to hitch a ride on a United Launch Alliance Vulcan Centaur rocket making its maiden voyage under a Nasa commercial partnership. But the boxy robot's manifest also includes payloads from two companies -- Elysium Space and Celestis -- that will contain cremated remains and DNA to stay on the Moon, inside the lander, forever.
