The Space Research Vessel Marina(外宇宙調査船 マリーナGaiuchū Chōsa-sen Marīna) (named only in the first Metroid manga) was a Galactic Federation spacecraft that investigated Planet SR-388 and departed with the earliest Metroid specimens since the creatures were introduced to that location. It is stated in various texts that it was heading to both Galactic Federation Headquarters and Earth, implying that the former is located at the latter. This craft was raided and destroyed by Space Pirates for the Metroid specimens before it could reach it's destination, and the Pirates brought the creatures to Zebes, Tallon IV, Aether, and other worlds to be tested and multiplied.
