Mars rover aims to grab a piece of history

[Idris_A]

Its get that we will be able to uncover the history of mars with these samples however it will take too much time for it to arrive back to earth, climate change might already made earth into a desert where everything is dead and we wasted our efforts in doing this, we should focus on either moving from earth quickly or stop climate change.

True but what if uncover information that could change our perspective of the universe as we know it.
