Mars is extraordinarily cold and dry, like our most arid deserts. Harsh but possibly not totally lifeless. There is a chance of life there, hidden away perhaps in thin layers of brines just a couple of centimeters below the surface, or as spores within the dust. Our astronauts will be covered in microbes from Earth too and our habitats filled with life. What happens when life mixes together from these two biospheres? This might be their first meeting for billions of years, or the first time ever, as astrobiologists haven't yet ruled out the possibility that Martian life is independently evolved. And if the more optimistic projections of Elon Musk, some NASA enthusiasts, and Bill Nye and others are fulfilled, then this encounter may happen as soon as the 2030s, perhaps sooner. Are we ready for it?
