Celestis Memorial Spaceflights make the dream of spaceflight a reality by launching a symbolic portion of cremated remains into near-space, Earth orbit, to the lunar surface or even beyond. You or your loved one will venture into space as part of a real space mission, riding alongside a commercial or scientific satellite. There isn’t a more compelling memorial service for someone who loves science fiction, marvels at space or simply longs to be at one with the cosmos.
