Nautilus (Verne) from seawater) is the craft's primary power source for propulsion and other services. "Nautilus" is double-hulled, and is further separated into water-tight compartments. Its top speed is . Its displacement is submerged. In Captain Nemo's own words: "Nautilus" uses floodable tanks in order to adjust buoyancy and so control its depth. The pumps that evacuate these tanks of water are so powerful that they produce large jets of water when the vessel emerges rapidly from the surface of the water. This leads many early observers of "Nautilus" to believe that the vessel is some species of whale, or perhaps a

Because of this, the crew used it as sleeping quarters, and also as a place to perform personal hygiene activities. Yi So-yeon also used it as laboratory space where she performed nanotechnology experiments. On 5 September 2008, "Jules Verne" undocked and manoeuvred to an orbital position 5 km below the ISS. It remained in that orbit until the night of 29 September. At 10:00:27
