And we wanted to know this both for being able to go somewhere else in the universe -- if we were going to go to Mars, for instance, would we take a biosphere with us, to live in it?
I volíem saber això per ser capaços d'anar a un altre lloc a l'univers, si anem a Mart, per exemple, ens podriem emportar una biosfera amb nosaltres, per poder viure-hi a dins?
