NASA explores. From its earliest days of sounding rockets and balloon-borne instruments, to Apollo and Hubble and missions to Mars. This mission of exploration has also always focused on our own corner of the universe, Earth - the home frontier. Earth is still the only planet we've ever been to, as this video explains.
