Is there life under the icy crust of Europa........?

The Matrian meteorite showed incontrovertible traces of chemical compounds which only come from LIFE, so I view Mars as either carrying Life, or having carried it. Once established, Life is a tenacious little blighter, it doesn't go down without a fight. Sure it may not be Star-Trek alien races, more like the stubborn little blobls of organic matter that stain rocks in Antartica, taking ten years to reach the size of a shirt-on - though some of them are now dinner-plate sized... We will wait an AWFUL long time to have a conversation with something like that!
