There are many excellent reasons to go to Mars, but for anyone to tell you that Mars will be there to back up humanity is like the captain of the Titanic telling you that the real party is happening later on the lifeboats.
Marsile minekuks on palju häid põhjuseid, aga väita, et Marss on inimkonna varupaik, on sama hea,  kui Titanicu kapten ütleks teile, et päris pidu toimub tegelikult hiljem päästepaatides.
