foreign

2
00:00:10,730 --> 00:00:08,330
the Curiosity Rover has discovered lots

3
00:00:12,830 --> 00:00:10,740
of evidence of ancient Lakes on Mars but

4
00:00:14,629 --> 00:00:12,840
what we saw in this Panorama surprised

5
00:00:16,910 --> 00:00:14,639
us

6
00:00:17,930 --> 00:00:16,920
curiosity is currently exploring Mount

7
00:00:19,550 --> 00:00:17,940
Sharp

8
00:00:20,750 --> 00:00:19,560
you can see the upper part of the

9
00:00:22,970 --> 00:00:20,760
mountain here

10
00:00:25,310 --> 00:00:22,980
the whole mountain is three miles tall

11
00:00:28,490 --> 00:00:25,320
but we're down in the foothills

12
00:00:30,650 --> 00:00:28,500
in 2022 the Rover started exploring a

13
00:00:32,389 --> 00:00:30,660
unique feature on Mars called the marker

14
00:00:35,270 --> 00:00:32,399
band

15
00:00:36,889 --> 00:00:35,280
it's a dark thin layer of rock that

16
00:00:38,030 --> 00:00:36,899
stands out from the layers above and

17
00:00:40,610 --> 00:00:38,040
below it

18
00:00:43,010 --> 00:00:40,620
we first saw it in Orbiter images years

19
00:00:45,170 --> 00:00:43,020
before we launched

20
00:00:47,750 --> 00:00:45,180
what created this winding layer of hard

21
00:00:49,549 --> 00:00:47,760
rock is a mystery but curiosity can help

22
00:00:52,729 --> 00:00:49,559
us understand what formed the marker

23
00:00:57,110 --> 00:00:54,590
we first discovered that the Rocks

24
00:00:59,029 --> 00:00:57,120
within the marker band are really hard

25
00:01:01,490 --> 00:00:59,039
Curiosity has faced some challenges

26
00:01:02,750 --> 00:01:01,500
drilling into them here's two of our

27
00:01:05,090 --> 00:01:02,760
attempts

28
00:01:06,440 --> 00:01:05,100
but we might find a softer spot on the

29
00:01:07,969 --> 00:01:06,450
road ahead

30
00:01:10,370 --> 00:01:07,979
[Music]

31
00:01:12,469 --> 00:01:10,380
nearby we found an exciting scientific

32
00:01:14,510 --> 00:01:12,479
clue

33
00:01:16,789 --> 00:01:14,520
these rippled textures were created

34
00:01:20,390 --> 00:01:16,799
billions of years ago by waves in a

35
00:01:24,170 --> 00:01:22,429
we've climbed through many Lake deposits

36
00:01:31,070 --> 00:01:24,180
during our mission but have never seen

37
00:01:35,450 --> 00:01:33,289
this was especially surprising since the

38
00:01:37,560 --> 00:01:35,460
area we're in probably formed at a time

39
00:01:39,710 --> 00:01:37,570
when Mars was becoming more dry

40
00:01:43,069 --> 00:01:39,720
[Music]

41
00:01:47,149 --> 00:01:45,350
just above the rippled layer is another

42
00:01:49,069 --> 00:01:47,159
intriguing clue

43
00:01:51,830 --> 00:01:49,079
these rocks have a very repetitive

44
00:01:54,230 --> 00:01:51,840
pattern in their spacing and thickness

45
00:01:56,450 --> 00:01:54,240
we see lots of layers on Mars but

46
00:01:58,850 --> 00:01:56,460
they're rarely this regular we're not

47
00:02:01,429 --> 00:01:58,860
sure what caused this rhythmic pattern

48
00:02:03,289 --> 00:02:01,439
weather or climate Cycles like dust

49
00:02:05,640 --> 00:02:03,299
storms happening at periodic intervals

50
00:02:15,570 --> 00:02:05,650
are possible explanations

51
00:02:16,670 --> 00:02:15,580
[Music]

52
00:02:19,010 --> 00:02:16,680
[Applause]

53
00:02:21,770 --> 00:02:19,020
look at these gorgeous layered Hills and

54
00:02:23,690 --> 00:02:21,780
cliffs that curiosity is headed toward

55
00:02:28,729 --> 00:02:23,700
if this was on Earth we'd probably make

56
00:02:33,410 --> 00:02:30,949
in the distance here we can see debris

57
00:02:35,449 --> 00:02:33,420
in a valley called Gettys Valles

58
00:02:37,790 --> 00:02:35,459
this was washed down here by wet

59
00:02:39,410 --> 00:02:37,800
landslides very late in Mount Sharp's

60
00:02:41,390 --> 00:02:39,420
history

61
00:02:43,430 --> 00:02:41,400
this Landslide debris is probably the

62
00:02:44,809 --> 00:02:43,440
most recent evidence of water that we'll

63
00:02:47,210 --> 00:02:44,819
ever see

64
00:02:49,250 --> 00:02:47,220
it will allow us to study layers higher

65
00:02:54,350 --> 00:02:49,260
up on Mount sharp that we can't reach

66
00:02:58,190 --> 00:02:56,270
Curiosity has driven through some

67
00:03:00,589 --> 00:02:58,200
amazing scenery and we've learned so

68
00:03:03,050 --> 00:03:00,599
much about Mars's ancient climate

69
00:03:04,880 --> 00:03:03,060
but even after 10 years there's so much
