We need to explore as much as
we can. Also, i am quite sure,
that in a few hundred to a
thousand years Earth will be

new place to go...
Exploring the unknown is a
good step for educational

exploring other planets is
educational
i do not know anything about

its good,i think..
Such missions are necessary
to look for life in Mars
