No siderite in some ancient soils therefore implied lower levels of carbon dioxide. Ohmoto and his associates, however, looked at four, rather than one, parameters involved in siderite formation.

A NASA rover taking rock samples on Mars has uncovered a plentiful mineral that was invisible to orbiters studying the Red Planet from space. Scientists say the discovery of siderite, a type of ...

The siderite discovery also has significant implications for the search for life. If Mars had warm, wet conditions for a billion years after its formation, this period represents a prime window of ...

A mineral called siderite found abundantly in rock drilled by a NASA rover on the surface of Mars is providing fresh evidence of the planet's warmer and wetter ancient past when it boasted ...

NASA’s Curiosity Mars rover sees its tracks receding into the distance at the 'Ubajara' site. This site is where the rover made the discovery of siderite, a mineral that may help explain the ...

Scientists have pondered why Mars seemed to be missing sufficient carbonates indicative of its warm, wet past. Now, NASA’s Curiosity rover may have just solved the mystery.

WASHINGTON — A mineral called siderite found abundantly in rock drilled by a NASA rover on the surface of Mars is providing fresh evidence of the planet's warmer and wetter ancient past when it ...
