There is only one creature known to man which can survive the ravages of deep space.
It is the water bear - officially known as the tardigrade - and despite being a fraction of a millimetre in length and mostly consigned to a lazy life exploring pond moss, it is almost indestructible.
You can freeze it at close to absolute zero - at minus 273C - or heat it to above 151C.
Or you could keep it without water for a decade, subject it to almost any kind of pressure, or send it into the radiation-filled vacuum of space where it can survive beyond ten days without any damage.
It is just one of the micro-sized and extraordinary bugs living in our back gardens - or even in our own bodies.
