Title: Has NASA found the food source for early life on Mars?
Post by: chris on 10/06/2018 14:05:10

NASA announced this week that their Curiosity Rover, which has been trundling around on the surface of Mars for about 6 years, has uncovered the best evidence yet of a home for early Martian life.

What does everyone think?

The methane levels on Mars (~0.5 ppb) are only a thousandth of those on stone-age Earth.
Not necessarily proof of life: could be abiotic

Thanks; but I thought that greater excitement - at least at this stage - was around the molecules that were there in what would have been this lake bed sediment. There were various organics and sulphur compounds, which would have made for fine Martian food, albeit for bacteria-sized aliens...
