1
00:00:08,270 --> 00:00:06,349
one of the key discoveries think the

2
00:00:10,970 --> 00:00:08,280
Cassini orbiter and the Huygens probe

3
00:00:14,390 --> 00:00:10,980
revealed for us was discovering the

4
00:00:17,210 --> 00:00:14,400
liquid lakes on Titan Cassini was able

5
00:00:20,120 --> 00:00:17,220
to look at the lakes get a sense of the

6
00:00:22,189 --> 00:00:20,130
course composition of the lakes but

7
00:00:24,950 --> 00:00:22,199
nothing about the organic molecules that

8
00:00:26,300 --> 00:00:24,960
are dissolved in the lakes the Titan

9
00:00:28,400 --> 00:00:26,310
Saturn's system mission is a

10
00:00:30,800 --> 00:00:28,410
three-in-one mission with an orbiter for

11
00:00:32,749 --> 00:00:30,810
Titan a balloon that will float through

12
00:00:34,819 --> 00:00:32,759
Titan's atmosphere and a lander that

13
00:00:37,160 --> 00:00:34,829
will splash down on one of the northern

14
00:00:39,440 --> 00:00:37,170
lakes of Titan this mission will

15
00:00:41,900 --> 00:00:39,450
actually go into a lake sample the

16
00:00:45,319 --> 00:00:41,910
liquid directly see what the organic

17
00:00:47,630 --> 00:00:45,329
molecules are that are present the Titan

18
00:00:51,049 --> 00:00:47,640
Saturn's system mission also will go to

19
00:00:53,420 --> 00:00:51,059
Enceladus but tinier moon a thousand

20
00:00:56,360 --> 00:00:53,430
times smaller than Titan which has

21
00:00:58,340 --> 00:00:56,370
volcanoes geysers essentially that are

22
00:01:00,680 --> 00:00:58,350
spewing material from the inside of this

23
00:01:02,869 --> 00:01:00,690
moon outward and it's a chance to see

24
00:01:04,969 --> 00:01:02,879
whether there might be molecules that

25
00:01:07,399 --> 00:01:04,979
would indicate that life has actually

26
00:01:09,890 --> 00:01:07,409
formed within the source region of these

27
00:01:11,840 --> 00:01:09,900
geysers these geysers have water ice and

28
00:01:14,090 --> 00:01:11,850
we strongly suspect that there's liquid

29
00:01:16,130 --> 00:01:14,100
water in the region that these geysers

30
00:01:18,200 --> 00:01:16,140
are coming from we know there are

31
00:01:22,429 --> 00:01:18,210
organic molecules there because they've

32
00:01:24,350 --> 00:01:22,439
been measured by Cassini the ability to

33
00:01:27,170 --> 00:01:24,360
follow this up quickly is essential

34
00:01:29,330 --> 00:01:27,180
because with cassini-huygens we have now

35
00:01:31,460 --> 00:01:29,340
trained a generation of scientists who

36
00:01:33,620 --> 00:01:31,470
are ready to take a new generation of

37
00:01:36,140 --> 00:01:33,630
instruments and capabilities back to

38
00:01:38,030 --> 00:01:36,150
Titan and Enceladus and really answer

39
00:01:41,260 --> 00:01:38,040
the questions that cassini-huygens has

40
00:01:45,289 --> 00:01:41,270
left for us and that continuity of

41
00:01:47,240 --> 00:01:45,299
knowledge and of enthusiasm is essential

42
00:01:49,429 --> 00:01:47,250
and very difficult to maintain in the

43
00:01:52,460 --> 00:01:49,439
outer solar system because trip times

44
00:01:54,889 --> 00:01:52,470
are so long the Titan Saturn's system

45
00:01:56,510 --> 00:01:54,899
mission really as Jules Verne realized

46
00:01:58,520 --> 00:01:56,520
it's a kind of planetary exploration

47
00:02:01,010 --> 00:01:58,530
that we have never ever done before

48
00:02:03,800 --> 00:02:01,020
anywhere else in the solar system and

49
00:02:06,840 --> 00:02:03,810
can only be done on Titan

50
00:02:09,889 --> 00:02:06,850
this mission will touch the human heart

51
00:02:12,840 --> 00:02:09,899
in terms of the way is exploring this

52
00:02:15,000 --> 00:02:12,850
fascinating world it will be floating on

53
00:02:17,490 --> 00:02:15,010
the surface of a lake it will be

54
00:02:19,530 --> 00:02:17,500
floating through the atmosphere it will

55
00:02:22,790 --> 00:02:19,540
be revealing the entire surface from

56
00:02:24,900 --> 00:02:22,800
orbit at the same time as we think of

57
00:02:27,780 --> 00:02:24,910
exploration of unveiling a new world
