Life On Mars Might Be Revealed Through The Detection Of Vanadium
The key to finding out whether or not life once existed on Mars, or could exist in the future, might come down to microscopic data.
A paper in the journal Astrobiology, says that researchers taking part in the search for life might need to rely on the chemical analysis of rock samples from the planet. This type of analysis could reveal microfossils that show whether or not there was once life on Mars simply through the presence of the element vanadium.
