12、,and flash floods rushed over the land.And Mars continues to throw out new enticements with each landing or orbital pass made by spacecrafts.Background Information Volcano on MarsAmong our discoveries about Mars,one stands out above all others:the possible presence of liquid water on Mars,either in
13、its ancient past or preserved in the subsurface today.Water is key because almost everywhere we find water on Earth,we find life.If Mars once had liquid water,or still does today,its compelling to ask whether any microscopic life forms could have developed on its surface.Is there any evidence of lif
