Asteroid impacts+hydrogen = recipe for Mars life
A new study reveals asteroid impacts on ancient Mars could have produced key ingredients for life if the Martian atmosphere was rich in hydrogen. An early hydrogen-rich atmosphere on Mars could also explain how the planet remained habitable after its … Continue reading

Curiosity detects biologically useful nitrogen at Rocknest, John Klein, and Cumberland sites
A team using the Sample Analysis at Mars (SAM) instrument suite aboard NASA’s Curiosity rover has made the first detection of nitrogen on the surface of Mars from release during heating of Martian sediments. The nitrogen was detected in the … Continue reading

Was nitrogen in the early Mars atmosphere a key to ancient habitability?
Scientists have long suspected that ancient Mars had a thicker atmosphere and temperatures warmer and far more habitable than at present. But modelers have difficulties making the numbers come out right,
