Speleology Speleology Speleology is the scientific study of caves and other karst features, their make-up, structure, physical properties, history, life forms, and the processes by which they form (speleogenesis) and change over time (speleomorphology). The term "speleology" is also sometimes applied to the recreational activity of exploring caves, but this is more properly known as "caving" or "potholing", or (not usually by participants) by the uncommon American term "spelunking". Speleology and caving are often connected, as the physical skills required for "in situ" study are the same. Speleology is a cross-disciplinary field that combines the knowledge of chemistry, biology, geology, physics,
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.
