1
00:00:08,549 --> 00:00:06,309
one of the key discoveries that the

2
00:00:10,950 --> 00:00:08,559
cassini orbiter and the huygens probe

3
00:00:13,350 --> 00:00:10,960
revealed for us was discovering the

4
00:00:16,150 --> 00:00:13,360
liquid lakes on titan

5
00:00:18,870 --> 00:00:16,160
cassini was able to look at the lakes

6
00:00:21,349 --> 00:00:18,880
get a sense of the course composition of

7
00:00:22,870 --> 00:00:21,359
the lakes but nothing about the organic

8
00:00:24,310 --> 00:00:22,880
molecules that are dissolved in the

9
00:00:26,390 --> 00:00:24,320
lakes

10
00:00:28,310 --> 00:00:26,400
the titan saturn system mission is a

11
00:00:29,269 --> 00:00:28,320
three-in-one mission with an orbiter for

12
00:00:30,710 --> 00:00:29,279
titan

13
00:00:32,630 --> 00:00:30,720
a balloon that will float through

14
00:00:34,709 --> 00:00:32,640
titan's atmosphere and a lander that

15
00:00:36,310 --> 00:00:34,719
will splash down on one of the northern

16
00:00:38,150 --> 00:00:36,320
lakes of titan

17
00:00:41,190 --> 00:00:38,160
this mission will actually go into a

18
00:00:42,869 --> 00:00:41,200
lake sample the liquid directly see what

19
00:00:44,630 --> 00:00:42,879
the organic molecules are that are

20
00:00:47,110 --> 00:00:44,640
present

21
00:00:50,549 --> 00:00:47,120
the titan saturn system mission also

22
00:00:52,869 --> 00:00:50,559
will go to enceladus the tinier moon a

23
00:00:55,910 --> 00:00:52,879
thousand times smaller than titan

24
00:00:57,590 --> 00:00:55,920
which has volcanoes geysers essentially

25
00:00:59,910 --> 00:00:57,600
that are spewing material from the

26
00:01:01,830 --> 00:00:59,920
inside of this moon outward and it's a

27
00:01:04,229 --> 00:01:01,840
chance to see whether there might be

28
00:01:05,830 --> 00:01:04,239
molecules that would indicate that life

29
00:01:07,350 --> 00:01:05,840
has actually formed

30
00:01:09,990 --> 00:01:07,360
within the source region of these

31
00:01:11,990 --> 00:01:10,000
geysers these geysers have water ice and

32
00:01:14,230 --> 00:01:12,000
we strongly suspect that there's liquid

33
00:01:15,429 --> 00:01:14,240
water in the region that these geysers

34
00:01:17,350 --> 00:01:15,439
are coming from

35
00:01:18,789 --> 00:01:17,360
we know there are organic molecules

36
00:01:21,510 --> 00:01:18,799
there because they've been measured by

37
00:01:26,550 --> 00:01:23,749
the ability to follow this up quickly is

38
00:01:28,390 --> 00:01:26,560
essential because with cassini huygens

39
00:01:30,710 --> 00:01:28,400
we have now trained a generation of

40
00:01:32,069 --> 00:01:30,720
scientists who are ready to take a new

41
00:01:35,190 --> 00:01:32,079
generation of instruments and

42
00:01:36,789 --> 00:01:35,200
capabilities back to titan and enceladus

43
00:01:39,429 --> 00:01:36,799
and really answer the questions that

44
00:01:42,789 --> 00:01:39,439
cassini-huygens has left for us

45
00:01:44,149 --> 00:01:42,799
and that continuity of knowledge and of

46
00:01:46,469 --> 00:01:44,159
enthusiasm

47
00:01:48,469 --> 00:01:46,479
is essential and very difficult to

48
00:01:51,030 --> 00:01:48,479
maintain in the outer solar system

49
00:01:53,109 --> 00:01:51,040
because trip times are so long

50
00:01:55,670 --> 00:01:53,119
the titan saturn system mission really

51
00:01:57,990 --> 00:01:55,680
is jules verne realized it's a kind of

52
00:01:59,670 --> 00:01:58,000
planetary exploration that we have never

53
00:02:01,910 --> 00:01:59,680
ever done before anywhere else in the

54
00:02:04,550 --> 00:02:01,920
solar system and can only be done on

55
00:02:10,150 --> 00:02:07,590
this mission will touch the human heart

56
00:02:12,790 --> 00:02:10,160
in terms of the way it's exploring this

57
00:02:14,390 --> 00:02:12,800
fascinating world it will be floating on

58
00:02:15,910 --> 00:02:14,400
the surface of a lake

59
00:02:18,309 --> 00:02:15,920
it will be floating through the

60
00:02:20,390 --> 00:02:18,319
atmosphere it will be revealing the

61
00:02:21,670 --> 00:02:20,400
entire surface from orbit at the same

62
00:02:24,309 --> 00:02:21,680
time

63
00:02:27,350 --> 00:02:24,319
as we think of exploration of unveiling
