Whatever organic chemicals may be produced on Mars or delivered to Mars face several possible modes of being transformed or destroyed. Organic chemicals are molecular building block of life, although they can be made without the presence of life. Whether or not organic chemicals are produced by processes on Mars, some are delivered to the planet aboard meteorites and dust from asteroids and comets.

Mars Has Ways to Make Organics Hard to Find

This illustration portrays some of the reasons why finding organic chemicals on Mars is challenging. Whatever organic chemicals may be produced on Mars or delivered to Mars face several possible modes of being transformed or destroyed.

A careful study of images taken by the NASA rover Curiosity has revealed intriguing similarities between ancient sedimentary rocks on Mars and structures shaped by microbes on Earth. The findings suggest, but do not prove, that life may have existed ear

Data graphed here are examples from the Sample Analysis at Mars (SAM) laboratory's detection of Martian organics in a sample of powder that the drill on NASA's Curiosity Mars rover collected from a rock target called "Cumberland." SAM's analysis of the Cumberland sample yielded the first definitive detection of any Martian organic chemicals in material on the surface of Mars.

Veiny 'Garden City' Site and Surroundings on Mount Sharp, Mars - This March view from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover shows a site with a network of prominent mineral veins below a cap rock ridge on lower Mount Sharp.

NASA's Curiosity Mars rover sees this view to the south at the Kimberley waypoint. Multiple sandstone beds in the foreground display systematic inclination possibly indicating progressive build-out of the sediments toward Mount Sharp.
