a dog there s a little brain and i say yes our brain is a little bigger but first earthlike are things we can t understand and our own brains may be one of those things it cannot be understood by human beings. the presence of downloading the contents of our brains onto a machine will remain science fiction for a long time to come still fervent research is being conducted into the field new technologies continue to be developed that help advance brain research and more and more robots are built that are modeled on humans. no one can predict today where scientific progress will lead to more. who can say how human machines will be in fifty or one hundred years all. to wash the stench humans will become vika machines we may not be aware of it but when our day in the foundation for a new era an era in which slowly but surely the boundaries will blow up between
mars is the most earthlike of any of the planets in our solar system, that s why we choose to explore it. reporter: just getting that mobile lab to mars was an unprecedented fete of engineering, 34 million miles away. the real discovery is history of life. rock analysis shows 2 billion years ago there were stream beds with running water and environment that could support microbes. it added up to understanding this environment as being chemically one that was favorable for life, not in a harsh way, a benign environment much like earth. reporter: the rover sent back more than 35,000 images of mars, giving a window to millions of online viewers and making a steady trek at a clip of about 100 yards a day. nasa will send another spacecraft to mars in november
