By studying streams on the UK coast, experts have calculated how much organic matter we might find on Mars, and where to look.
Dorset is home to highly acidic sulphur streams that host bacteria that thrive in extreme conditions. One such environment, in St Oswald’s Bay, mimics the conditions on Mars billions of years ago.
Now, scientists from Imperial College London have found ancient traces of fatty acids - key building blocks of biological cells – in Dorset’s acidic streams.
Because the environment is so similar to that of Mars during its middle-ages, the findings hint that life might once have existed on the Red Planet. ...
