Speleology to cave science in the world. The growth of speleology is directly linked with that of the sport of caving, both because of the stimulation of public interest and awareness, and the fact that most speleological field-work has been conducted by sport cavers. The creation of an accurate, detailed map is one of the most common technical activities undertaken within a cave. Cave maps, called "surveys", can be used to compare caves to each other by length, depth and volume, may reveal clues on speleogenesis, provide a spatial reference for further scientific study, and assist visitors with route-finding. Caves provide
Exploration of Mercury of Mercury. The "MESSENGER" mission was designed to study the characteristics and environment of Mercury from orbit. Specifically, the scientific objectives of the mission are: This mission to Mercury is to include two satellites: the Mercury Planetary Orbiter (MPO) and Mio (Mercury Magnetospheric Orbiter, MMO). Each orbiter has a distinct purpose: the MPO is to acquire images in several wavelengths to map the surface and exosphere composition of Mercury, and Mio’s is to study the magnetosphere. The European Space Agency and Japan Aerospace Exploration Agency are working in conjunction on "BepiColombo" and will each provide one of the orbiters. The
