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?
Me tahtsime seda teada juhuks, kui me saaks minna kusagile mujale universumis - kui me tahaksime näiteks minna Marsile, kas me võtaks biosfääri endaga kaasa, et selles elada?
