Large Magellanic Cloud
The Milky Way's largest satellite galaxy — a stellar nursery, supernova laboratory, and window into the early universe, visible to the naked eye from the Southern Hemisphere.
Heater units (RHUs)
Passive plutonium-238 heat sources — no moving parts, no wiring, just continuous warmth for spacecraft surviving the deep cold of space.
Enceladus
Saturn's icy moon with a global saltwater ocean, erupting geysers, and some of the Solar System's best odds for harbouring life.
Pollux
