MARS a day ...............

The red planet , people have long speculated that there is life on Mars because it is like ours in many ways , with polar caps , canyons , volcanoes and lowland plains . But it is also very different - there is no water visible and its atmosphere has virtually no oxygen . We have sent several spacecraft there but have found no sign of life , not even of mirobial life , confirming that there is more to life than time and chance .
