Alan Shepard (November 18, 1923 – July 21, 1998) was an American astronaut, naval aviator, test pilot, and businessman. In 1961 he became the second person and the first American to travel into space, and in 1971 he walked on the Moon (pictured). Shepard saw action with the surface navy during World War II. He became a naval aviator in 1947, and a test pilot in 1951. He was one of NASA's original Mercury Seven astronauts in 1959, and in May 1961 he made his first spaceflight: Mercury-Redstone 3, the first crewed Project Mercury flight. In 1971, he commanded the Apollo 14 mission, piloting the Apollo Lunar Module Antares. He became the fifth and the oldest person to walk on the Moon, and the only one of the Mercury Seven astronauts to do so. He was promoted to rear admiral in 1971, and was the first astronaut to reach that rank. He was Chief of the Astronaut Office from November 1963 to July 1969, and from June 1971 to April 1974. He retired from NASA and the United States Navy in July 1974. (Full article...)

Sphalerite is a sulfide mineral with the chemical formula (Zn,Fe)S. It is found in a variety of deposit types, and is found in association with galena, chalcopyrite, pyrite (and other sulfides), calcite, dolomite, quartz, rhodochrosite, and fluorite. Sphalerite is an important ore of zinc, with around 95 percent of all primary zinc extracted from its ore. Due to its variable trace-element content, sphalerite is also an important source of several other metals such as cadmium, gallium, germanium and indium. The zinc in sphalerite is also used to produce brass. This sample was extracted in Creede, Colorado, and features black tetrahedral crystals of sphalerite up to 8 mm (0.31 in) in size, with minor chalcopyrite and calcite, in a 4.5 cm × 3.0 cm × 2.0 cm (1.77 in × 1.18 in × 0.79 in) matrix. This photograph was focus-stacked from 125 separate images. Photograph credit: Ivar Leidus
