Mars life search gets boost as rover test distinguishes mirrored biosignature molecules

Billions of years ago, environmental conditions on Mars were significantly more hospitable than they are today. Our neighboring planet was likely warm, humid and surrounded by a dense atmosphere. Whether simple microorganisms could have evolved at that time remains an open question.

Billions of years ago, environmental conditions on Mars were significantly more hospitable than they are today. Our neighbouring planet was likely warm, humid, and surrounded by a dense atmosphere. Whether simple microorganisms could have evolved at that time, remains an open question. NASA rovers have found organic molecules in Martian rock, but none of them […] The post Mars Mission: A Stress Test For The Search For Life appeared first on Astr…

ExoMars: A Stress Test for the Search for Life

Starting in 2030, ESA’s rover Rosalind Franklin will search for traces of life on Mars. The MPS is contributing a scientific instrument to the mission. The instrument determines, among other things, a crucial property of organic molecules: their chirality. This reveals whether the molecules were ever part of a living organism. In preparation, researchers have successfully used this principle for the first time to analyse two particularly relevant chemical compounds in meteorite samples. The measurements also reveal evidence that meteorites “collect” remnants of fossil fuels as they plunge through the Earth’s atmosphere.
