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
Scientific information from the Mars Exploration Rover mission the Martian sky. A transit of Mercury from Mars took place on January 12, 2005 from about 14:45 UTC to 23:05 UTC, but camera resolution did not permit seeing Mercury's 6.1" angular diameter. Transits of Deimos across the Sun were seen, but at 2' angular diameter, Deimos is about 20 times larger than Mercury's 6.1" angular diameter. Scientific information from the Mars Exploration Rover mission NASA's 2003 Mars Exploration Rover Mission has amassed an enormous amount of scientific information related to the Martian geology and atmosphere, as well as providing some astronomical observations from Mars.
