1
00:00:08,709 --> 00:00:06,760
as we travel farther and deeper into

2
00:00:10,749 --> 00:00:08,719
space communication between the ground

3
00:00:12,940 --> 00:00:10,759
and astronauts will become more and more

4
00:00:15,369 --> 00:00:12,950
complicated how do you feel when you've

5
00:00:16,690 --> 00:00:15,379
had a bad phone connection or can't get

6
00:00:18,460 --> 00:00:16,700
through to someone you're trying to

7
00:00:20,320 --> 00:00:18,470
reach well communication could be

8
00:00:22,480 --> 00:00:20,330
critical in handling medical or other

9
00:00:24,580 --> 00:00:22,490
emergency situations for astronauts

10
00:00:26,440 --> 00:00:24,590
traveling far from Earth a study is

11
00:00:27,970 --> 00:00:26,450
looking at how delays in communication

12
00:00:31,060 --> 00:00:27,980
may affect astronauts on the space

13
00:00:32,950 --> 00:00:31,070
station ISS commentator Lori Meggs at

14
00:00:35,590 --> 00:00:32,960
the NASA's Marshall Space Flight Center

15
00:00:38,830 --> 00:00:35,600
spoke to the PI to learn more about the

16
00:00:42,010 --> 00:00:38,840
comm delay assessment it's an evaluation

17
00:00:44,320 --> 00:00:42,020
of the impact of delays and

18
00:00:47,740 --> 00:00:44,330
communication to and from the

19
00:00:51,850 --> 00:00:47,750
International Space Station on human

20
00:00:53,830 --> 00:00:51,860
behavior performance and well-being so

21
00:00:55,960 --> 00:00:53,840
we're saying that the delays and not

22
00:00:58,540 --> 00:00:55,970
being able to communicate it will affect

23
00:01:01,090 --> 00:00:58,550
the behavior of a scholarship well you

24
00:01:03,190 --> 00:01:01,100
know the expectation is that as humans

25
00:01:06,250 --> 00:01:03,200
travel further and further into space

26
00:01:08,680 --> 00:01:06,260
and eventually to Mars that the length

27
00:01:12,219 --> 00:01:08,690
of time it takes to communicate to and

28
00:01:15,940 --> 00:01:12,229
from a space vehicle will grow larger

29
00:01:20,080 --> 00:01:15,950
and larger and in doing so the types of

30
00:01:24,130 --> 00:01:20,090
communications that are normally between

31
00:01:27,460 --> 00:01:24,140
the ground and the space crews will

32
00:01:30,550 --> 00:01:27,470
become compromised by the fact that it

33
00:01:32,320 --> 00:01:30,560
will take longer to ask a question or to

34
00:01:35,440 --> 00:01:32,330
get an answer to a question and

35
00:01:38,890 --> 00:01:35,450
particularly when performing certain

36
00:01:41,859 --> 00:01:38,900
vital tasks that may have implications

37
00:01:44,200 --> 00:01:41,869
for how successful accrue may be in

38
00:01:47,850 --> 00:01:44,210
performing the task how much autonomy

39
00:01:51,789 --> 00:01:47,860
they will have to exercise in order to

40
00:01:54,520 --> 00:01:51,799
complete assigned tasks and potentially

41
00:01:57,850 --> 00:01:54,530
you know the psychological ramifications

42
00:02:01,179 --> 00:01:57,860
that it may have in terms of levels of

43
00:02:03,550 --> 00:02:01,189
stress levels of uncertainty and so

44
00:02:05,200 --> 00:02:03,560
forth so how do you study that on the

45
00:02:08,559 --> 00:02:05,210
space station well on the space station

46
00:02:11,920 --> 00:02:08,569
we've had astronauts perform certain

47
00:02:12,650 --> 00:02:11,930
tasks that we vary in terms of their

48
00:02:16,360 --> 00:02:12,660
novel

49
00:02:20,360 --> 00:02:16,370
and their criticality or complexity

50
00:02:22,790 --> 00:02:20,370
under conditions of normal degrees of

51
00:02:27,620 --> 00:02:22,800
communication to and from earth and then

52
00:02:30,140 --> 00:02:27,630
a 50-second one-way delay and we monitor

53
00:02:33,890 --> 00:02:30,150
the performance of each task through

54
00:02:37,100 --> 00:02:33,900
audio recordings but we also at the end

55
00:02:40,130 --> 00:02:37,110
of each task ask a both round support

56
00:02:43,220 --> 00:02:40,140
personnel as well as the astronauts to

57
00:02:45,320 --> 00:02:43,230
complete questionnaires that let us know

58
00:02:47,840 --> 00:02:45,330
you know how much difficulty they

59
00:02:51,500 --> 00:02:47,850
experience in communicating to and from

60
00:02:54,770 --> 00:02:51,510
the ground how it impacted their ability

61
00:02:58,880 --> 00:02:54,780
to perform the task how much impact it

62
00:03:02,660 --> 00:02:58,890
had on both their own well-being levels

63
00:03:05,990 --> 00:03:02,670
of stress as well as the morale of the

64
00:03:07,880 --> 00:03:06,000
crew itself from that is are there any

65
00:03:10,430 --> 00:03:07,890
earth applications that this would

66
00:03:13,730 --> 00:03:10,440
relate to well delays in communication

67
00:03:17,170 --> 00:03:13,740
occur for a variety of reasons in all

68
00:03:19,510 --> 00:03:17,180
types of settings so in other remote in

69
00:03:23,390 --> 00:03:19,520
isolated environments on earth

70
00:03:25,790 --> 00:03:23,400
oftentimes even with the advantages of

71
00:03:28,880 --> 00:03:25,800
satellite communications there are

72
00:03:31,400 --> 00:03:28,890
instances when communications can be

73
00:03:33,560 --> 00:03:31,410
delayed for one reason or another you

74
00:03:35,600 --> 00:03:33,570
yourself may experience frustration when

75
00:03:38,620 --> 00:03:35,610
you send out an email and don't receive

76
00:03:42,040 --> 00:03:38,630
an instantaneous answer for example

77
00:03:45,170 --> 00:03:42,050
there are also maybe applications for

78
00:03:47,780 --> 00:03:45,180
individuals who are isolated and

79
00:03:50,110 --> 00:03:47,790
confined for a variety of reasons older

80
00:03:53,720 --> 00:03:50,120
adults who are homebound for instance

81
00:03:56,600 --> 00:03:53,730
who may need information and advice from

82
00:04:00,290 --> 00:03:56,610
health care providers or service

83
00:04:02,390 --> 00:04:00,300
providers and may experience delays in

84
00:04:05,680 --> 00:04:02,400
getting that types of communication

85
00:04:08,690 --> 00:04:05,690
we're really attempting to identify

86
00:04:10,280 --> 00:04:08,700
countermeasures or strategies which will

87
00:04:13,370 --> 00:04:10,290
improve both the quality of

88
00:04:17,930 --> 00:04:13,380
communication and perhaps reduce some of

89
00:04:21,320 --> 00:04:17,940
the the negative potentially negative

90
00:04:23,930 --> 00:04:21,330
aspects of not getting information in a

91
00:04:26,450 --> 00:04:23,940
timely fashion and needing to exercise

92
00:04:29,390 --> 00:04:26,460
more autonomy how do we prepare

93
00:04:32,210 --> 00:04:29,400
individuals or how do we prepare groups

94
00:04:35,660 --> 00:04:32,220
to do that will be one of the most

95
00:04:36,950 --> 00:04:35,670
important implications from the research
