Kairei, the support ship Launcher (a sampling station) Vehicle (a sediment probe) Samplers (a gravity corer or Smith Macintyre type sampler) Except for the sampler and the smaller size of the ROV itself, the system configuration is the same as for Kaikō. The launcher launches and recovers the ROV along with its sampler. Click here to see a photograph of ABISMO and its launcher, as well as RV Kairei, the support ship. The lower part of the launcher is constructed of a stainless steel framework, within which the vehicle is stored. Pressure hulls for electronic devices, a winch, a secondary cable drum and two electric transformers are located in the upper part of the launcher. The samplers include a gravity core sampler and a bottom grab sampler. There is also a docking system and an acoustic positioning system in the lower part of the launcher. The vehicle is hung in the launcher by the docking system. When the system detaches it and the cable drum feeds the secondary cable, the vehicle can dive down, and its position is measured by the acoustic positioning system. The position of the launcher is measured by RV Kairei, the support ship. The launcher also has a high-definition television (HDTV) camera with pan and tilt functions. Initial sea trials of ABISMO were conducted in 2007. The craft successfully reached a planned depth of 9,760-meters, the deepest part of Izu–Ogasawara Trench, where it collected core samples of sediment from the seabed. Plans are underway for a mission to the Challenger Deep. In June 2008, the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) deployed the 4,517-ton Deep Sea Research Vessel Kairei to the area of Guam for cruise KR08-05 Leg 1 and Leg 2. On 1–3 June 2008, during Leg 1, the Japanese robotic deep-sea probe ABISMO (Automatic Bottom Inspection and Sampling Mobile) on dives 11-13 almost reached the bottom about east of the Challenger Deep: "Unfortunately, we were unable to dive to the sea floor because the legacy primary cable of the Kaiko system was a little bit short. The 2-m long gravity core sampler was dropped in free fall, and sediment samples of 1.6m length were obtained. Twelve bottles of water samples were also obtained at various depths..." ABISMO's dive #14 was into the TOTO caldera (12°42.7777 N, 143°32.4055 E), about 60 nmi northeast of the deepest waters of the central basin of the
