- Anagalactic — Located, occurring, or extending beyond the limits of our galaxy (the Milky Way); situated in extragalactic space. In a cosmic structural sense, the term applies to celestial objects, radiations, or astronomical phenomena (such as nebulae, galaxy clusters, or cosmic rays) that originate or evolve outside the stellar system to which Earth belongs.
- Spacecraft — A spacecraft, cosmic vessel, or complex flight craft structurally designed and equipped to navigate in extra-atmospheric space, transport human crews or scientific payloads, and perform interplanetary or interstellar exploration missions. A spacecraft integrates advanced propulsion, regenerative life support systems, thermal and radiation shielding, and automated guidance equipment necessary for survival and operation in the vacuum of space.
