The Aether-class Science Vessel is a modular science, research and exploration vessel used by the UNSC and associated agencies for a variety of purposes. The Aether is, from top to bottom, fully modular, with a vast interior made of several modular lab areas and several modular cargo spaces. This allows the ship interior to be suited to any mission. Externally, it can fit a number of non-standard sensor packages and probe/satellite launching capacities.
