1
00:00:15,482 --> 00:00:16,082
Here.

2
00:00:16,082 --> 00:00:18,952
The engineers are constantly transmitting
and receiving signals

3
00:00:19,452 --> 00:00:22,022
through the Deep Space Network
or the DSN as we call it.

4
00:00:22,922 --> 00:00:25,058
The DSN is the primary way

5
00:00:25,392 --> 00:00:28,561
we send signals from here

6
00:00:28,561 --> 00:00:31,598
all the way to here.

7
00:00:31,598 --> 00:00:33,600
Over the next several minutes

8
00:00:33,600 --> 00:00:36,302
in this specially imagined spacecraft,

9
00:00:36,302 --> 00:00:39,339
we'll be going on a journey
to some of our most important missions

10
00:00:39,739 --> 00:00:43,576
and recent discoveries in the exciting
search for life in the universe.

11
00:00:44,544 --> 00:00:48,181
Each of us has looked up in the night
sky and wondered, Are we alone?

12
00:00:49,082 --> 00:00:51,317
Or just one of those points of light
harbor life?

13
00:00:52,185 --> 00:00:55,655
Now, for the first time,
JPL is tantalizingly close

14
00:00:55,989 --> 00:00:58,825
to answering that question.

15
00:00:59,025 --> 00:01:01,428
Let's look at one of the closest points
of light in the night sky.

16
00:01:02,128 --> 00:01:03,630
The planet Mars

17
00:01:04,764 --> 00:01:05,865
associate with life.

18
00:01:07,667 --> 00:01:10,437
We learned two key lessons from Curiosity.

19
00:01:11,971 --> 00:01:13,473
The first is that where you

20
00:01:13,473 --> 00:01:16,810
land and explore are critical.

21
00:01:16,810 --> 00:01:19,579
You have to go to the places that preserve

22
00:01:19,712 --> 00:01:22,415
remnants of those ancient days.

23
00:01:22,682 --> 00:01:25,552
Three and a half billion years ago,
when Mars was habitable.

24
00:01:26,986 --> 00:01:29,956
Secondly, we will always be limited

25
00:01:30,123 --> 00:01:33,593
in the amount of scientific equipment
we can take to the surface of Mars.

26
00:01:34,561 --> 00:01:36,696
Especially when it comes to looking for

27
00:01:36,696 --> 00:01:38,731
things as subtle as signs of ancient life.

28
00:01:40,533 --> 00:01:44,137
Saturn's moon Enceladus
actually has active geysers,

29
00:01:45,038 --> 00:01:47,640
and they've been photographed
by the Cassini spacecraft

30
00:01:47,974 --> 00:01:50,076
during its decade long mission at Saturn.

31
00:01:51,845 --> 00:01:54,180
That same tidal force that heats up

32
00:01:54,180 --> 00:01:57,750
the ice also cracks it allowing it to form

33
00:01:58,017 --> 00:02:00,587
These geyser like sprays

34
00:02:07,260 --> 00:02:10,130
JPL and NASA are actively working on missions

35
00:02:10,597 --> 00:02:14,934
to fly directly through the geysers,
analyzing the water droplets.
