It wouldn't be right, the first night on Mars, to make a loud noise, to introduce a strange, silly bright thing like a stove. It would be a kind of imported blasphemy. There'd be time for that later; time to throw condensed-milk cans in the proud Martian canals; time for copies of the New York Times to blow and caper and rustle across the lone gray Martian sea bottoms; time for banana peels and picnic papers in the fluted, delicate ruins of the old Martian valley towns. Plenty of time for that.
