Meteorites show modern Mars’ subsurface has ingredients to support life

Chemistry required to support microbial life, similar to what exists deep underground in the darkest places on Earth, is also occurring in the subsurface of Mars. That is the conclusion of new research led by scientists at Brown University and the University of Toronto, which examined the chemical composition of Martian meteorites that landed on Earth and also analysed data from Nasa’s Curiosity rover, as well as other orbiting spacecraft.
