Geochemists use platinum, silica, and ceramic crucibles, shown here in a glass container called a desiccator. Silica is used because it is resistant to extremely high temperatures and because it is chemically inert. Silicon, linked up with a pair of oxygen molecules as silicon dioxide, is known as silica.

When you’re planning to explore someplace new, it’s always a good idea to bring a map so you can avoid dangerous terrain. This is true whether you’re heading out for a hike on Earth or you’re landing a rover on Mars!

William T. Pecora, Director of the USGS from 1965 to 1971, is largely responsible for two major contributions to science in the public interest: the creation of a national earthquake research center at the USGS facility in Menlo Park, CA, and the Landsat series of Earth observing satellites.
