"It doesn't mean there's no life on Mars, but what it does mean is it's going to be harder to find," said Jacqueline Goordial, the McGill University researcher who led the study, in an interview with Rachelle Solomon on CBC's Breakaway.
Failure to find active microbes in coldest Antarctic soils has implications for search for life on Mars Natural Resource Sciences professor Lyle Whyte and postdoctoral fellow Jackie Goordial talk about their research which suggests that it is unlikely that it is unlikely that there is any microbial life to be found on Mars.

Weather, which changes day-to-day due to constant fluctuations in the atmosphere, and climate, which varies over decades, are familiar. More recently, a third regime, called “macroweather,” has been used to describe the relatively stable regime between weather and climate.
The temperature in the permafrost on Ellesmere Island in the Canadian high Arctic is nearly as cold as that of the surface of Mars. So the recent discovery by a McGill University led team of scientists of a bacterium that is able to thrive at –15ºC, the coldest temperature ever reported for bacterial growth, is exciting. The bacterium offers clues about some of the necessary preconditions for microbial life on both the Saturn moon Enceladus and Mars, where similar briny subzero conditions are thought to exist.
