1 00:00:05,240 --> 00:00:02,540 the radar that we've been flying around 2 00:00:07,509 --> 00:00:05,250 Saturn and passing by Titan periodically 3 00:00:10,730 --> 00:00:07,519 we've been able to map out the surface 4 00:00:13,310 --> 00:00:10,740 brightness as the radar sees it we see 5 00:00:16,220 --> 00:00:13,320 geologic processes that are very similar 6 00:00:19,730 --> 00:00:16,230 to what we see on the earth this is a 7 00:00:22,849 --> 00:00:19,740 computer generated 3d fly-through of an 8 00:00:25,820 --> 00:00:22,859 area of karst topography on Titan it was 9 00:00:28,250 --> 00:00:25,830 generated by inferring the topography 10 00:00:32,780 --> 00:00:28,260 and then laying a radar image down on 11 00:00:36,260 --> 00:00:32,790 top of the 3d map this area is an area 12 00:00:39,020 --> 00:00:36,270 called sukoon labyrinth on Titan it's an 13 00:00:41,150 --> 00:00:39,030 area of karst topography very similar to 14 00:00:44,600 --> 00:00:41,160 the karst topography we find on earth 15 00:00:49,459 --> 00:00:44,610 especially in places like Jamaica Puerto 16 00:00:52,700 --> 00:00:49,469 Rico or China it's an area where liquid 17 00:00:55,369 --> 00:00:52,710 methane here on Titan is dissolved the 18 00:00:57,650 --> 00:00:55,379 rocks and produced a residual landscape 19 00:01:01,040 --> 00:00:57,660 of just hills and valleys with no river 20 00:01:04,609 --> 00:01:01,050 valleys flowing through the area so it's 21 00:01:06,830 --> 00:01:04,619 yet again another process that we see on 22 00:01:09,020 --> 00:01:06,840 the earth that we find on Titan making
