Mars: September 2013


The quest for evidence of life on Mars could be more difficult than scientists previously thought. A scientific paper published today details the investigation of a chemical in the Martian soil that interferes with the techniques used by the Curiosity rover to test for traces of life. The chemical causes the evidence to burn away during the tests.

An instrument similar to those used on Earth by art detectives and to sense explosives at airports will be taken into space for the first time by ExoMars, the European Space Agency's mission to Mars in 2018. This Raman spectrometer will help space scientists to hunt for traces of Martian life.
