A review of a study called Viking Labeled Release, which saw two probes land on the Red Planet, has brought exciting claims that soil collected from Mars shows microbial life.
The crafts landed 4,000 miles from each other on Mars in the Seventies, but both yielded similarly shocking results following an analysis of Martian soil.
Once the soil had been returned to Earth, they underwent a series of tests including heating them, nutrient injection and being stored in the dark for two months.
Scientists noted that the samples showed signs of microbial life – and were uncannily similar to the same tests on soils from California, Alaska, and Antarctica.
