According to a new NASA laboratory experiment, rovers may have to dig about 6.6 feet (two meters) or more under the Martian surface to find signs of ancient life because ionizing radiation from space degrades small molecules ...

(Phys.org) —A new study in the Netherlands has found a deep-sea microbe living in high-temperature hydro-thermal vents can thrive on chlorate and perchlorate anions. Perchlorate, an ingredient in rocket fuel and fireworks, ...
(PhysOrg.com) -- In 1976 the NASA Viking landers took samples of soil on Mars and tested them for signs of organic carbon. A reinterpretation of the results now suggests the samples did contain organic compounds, but the ...
(PhysOrg.com) -- Experiments prompted by a 2008 surprise from NASA's Phoenix Mars Lander suggest that soil examined by NASA's Viking Mars landers in 1976 may have contained carbon-based chemical building blocks of life.

Perchlorates are the salts derived from perchloric acid (HClO4). They occur both naturally and through manufacturing. They have been used as a medicine for more than 50 years to treat thyroid gland disorders. They are used extensively within the pyrotechnics industry, and ammonium perchlorate is also a component of solid rocket fuel. Lithium perchlorate, which decomposes exothermically to give oxygen, is used in oxygen "candles" on spacecraft, submarines and in other esoteric situations where a reliable backup or supplementary oxygen supply is needed. Most perchlorate salts are soluble in water.
