﻿1
00:00:11.136 --> 00:00:11.886
So this weekend,

2
00:00:11.886 --> 00:00:15.348
the moon is going to give us an incredible
show, a real treat.

3
00:00:15.640 --> 00:00:18.560
All weekend long will be treated
to effectively a full moon.

4
00:00:18.768 --> 00:00:22.147
And it culminates on Sunday night
with this beautiful lunar eclipse.

5
00:00:22.355 --> 00:00:24.607
So starting at about 10 p.m.

6
00:00:24.607 --> 00:00:29.320
Eastern on Sunday night, the moon will
start passing through the Earth's shadow

7
00:00:29.529 --> 00:00:33.116
and right around
midnight will be the peak of this eclipse,

8
00:00:33.116 --> 00:00:36.536
when the moon will turn this
beautiful coppery reddish orange color

9
00:00:36.828 --> 00:00:39.622
and then gradually move
out of the Earth's shadow.

10
00:00:39.622 --> 00:00:43.418
So all night long, late Sunday
night into Monday morning on the East

11
00:00:43.418 --> 00:00:46.838
Coast, we'll be treated
to this beautiful lunar eclipse.

12
00:00:54.804 --> 00:00:57.557
So this weekend we are treated
to a spectacular

13
00:00:57.557 --> 00:01:01.352
sight of a full moon,
culminating in a lunar eclipse.

14
00:01:01.686 --> 00:01:05.440
Now, I would encourage people to go out
any time during the night, Saturday

15
00:01:05.440 --> 00:01:07.108
and Sunday night, even Friday night.

16
00:01:08.068 --> 00:01:12.447
Look up to the sky and you'll
see the beautiful majesty of a full moon.

17
00:01:12.822 --> 00:01:16.034
Now, during the eclipse,
if it's cloudy, if it's.

18
00:01:16.659 --> 00:01:20.163
If it's. If you're surrounded by trees
or tall buildings, you'll want to find

19
00:01:20.163 --> 00:01:23.416
a relatively open space
where you have a good view of the sky.

20
00:01:23.458 --> 00:01:27.295
Now, there's no one critical moment
that you have to be outside to see this.

21
00:01:27.545 --> 00:01:29.422
The eclipse will begin about 10 p.m.

22
00:01:29.422 --> 00:01:33.676
Eastern time on Sunday night,
reaching its peak just around midnight.

23
00:01:33.885 --> 00:01:35.762
And then gradually
the moon will be passing

24
00:01:35.762 --> 00:01:37.889
out of the earth's shadow
over the next few hours.

25
00:01:37.889 --> 00:01:41.726
So find your ideal location,
whether it's in your backyard

26
00:01:41.726 --> 00:01:44.020
or on the top of your building
or in some location,

27
00:01:44.020 --> 00:01:46.064
or have a beautiful, unobstructed
view of the sky.

28
00:01:46.064 --> 00:01:50.110
You want to be clear of bright lights
or tall buildings around you, if you can,

29
00:01:50.860 --> 00:01:53.154
and just relax and enjoy the show.

30
00:02:00.870 --> 00:02:03.790
The moon turns this beautiful red color
during the eclipse

31
00:02:03.790 --> 00:02:07.710
because of this really special connection
between the earth and the moon.

32
00:02:08.336 --> 00:02:10.797
Just the same reason
why when you go out at sunset

33
00:02:10.797 --> 00:02:14.342
or sunrise, the horizon turns
that beautiful red orange color.

34
00:02:14.676 --> 00:02:18.138
Well, now imagine
all of the sunrises and sunsets

35
00:02:18.138 --> 00:02:22.433
from the earth get projected onto
the surface of the moon when it passes in

36
00:02:22.559 --> 00:02:23.643
to the shadow of the earth.

37
00:02:23.643 --> 00:02:27.897
And so during the peak of the eclipse,
which is just to right around midnight

38
00:02:28.439 --> 00:02:31.067
Sunday night, East Coast time,

39
00:02:31.317 --> 00:02:34.195
the moon will turn this
beautiful, coppery brown color.

40
00:02:34.445 --> 00:02:37.615
And again, that's the projection
of all of the sunrises and sunsets

41
00:02:37.615 --> 00:02:39.659
on the earth onto the surface of the moon.

42
00:02:47.959 --> 00:02:50.044
We're preparing for the art of exploration

43
00:02:50.044 --> 00:02:53.506
of the South Pole of the Moon
by doing really two fundamental things.

44
00:02:53.506 --> 00:02:56.634
One is we're analyzing
the data that we've collected

45
00:02:56.634 --> 00:03:00.013
for the moon over the last 13 years,
thanks to the Lunar Reconnaissance

46
00:03:00.013 --> 00:03:03.558
Orbiter, a spacecraft
NASA's sent to the moon in 2009 to do

47
00:03:03.558 --> 00:03:07.812
just this, to help chart the the places
that we want to send astronauts.

48
00:03:07.812 --> 00:03:09.939
We want to send robotic missions to

49
00:03:09.939 --> 00:03:13.401
to look for scientifically interesting
and safe places to explore.

50
00:03:13.651 --> 00:03:14.903
And so, on one hand,

51
00:03:14.903 --> 00:03:18.656
we're studying that data to find
those ideal locations to send crew.

52
00:03:18.907 --> 00:03:22.410
We're also preparing those astronauts,
the Artemis astronauts have been selected

53
00:03:22.785 --> 00:03:27.540
to, you know, begin their education
on geology, on planetary science,

54
00:03:27.540 --> 00:03:30.585
so that when they're on the surface
of the moon, they can make the decisions

55
00:03:30.585 --> 00:03:34.464
of which samples to collect and what to do
while they're exploring the moon.

56
00:03:34.923 --> 00:03:37.967
So we're at this very exciting point
where we have the data,

57
00:03:37.967 --> 00:03:41.971
we have the talent, and it's now a matter
of of letting letting time march on

58
00:03:41.971 --> 00:03:45.683
and prepare for 2025 to send that
first crew to the South Pole of the moon.

59
00:03:54.108 --> 00:03:57.237
The Moon is a wonderful

60
00:03:57.237 --> 00:04:01.532
surface are a quarter of the processes
that occur across the solar system.

61
00:04:01.908 --> 00:04:06.329
When we look at the lunar surface,
we are gazing back to the earliest part

62
00:04:06.329 --> 00:04:09.207
of the history of our solar system, four
and a half billion years.

63
00:04:09.582 --> 00:04:11.876
And so when we look at the craters
that have formed

64
00:04:11.876 --> 00:04:13.711
on the surface of the moon
and we look at the

65
00:04:13.711 --> 00:04:17.548
the volcanic eruptions that have occurred
there, we are peering back in time.

66
00:04:17.840 --> 00:04:20.593
And indeed, when we study any other object
in the solar system,

67
00:04:20.593 --> 00:04:23.846
whether it's Mercury, whether it's Mars,
whether it's Pluto.

68
00:04:24.305 --> 00:04:27.350
Our understanding of the processes,
the changes that have occurred on

69
00:04:27.350 --> 00:04:31.771
those planets are in large part due
to the understanding we have of the moon.

70
00:04:31.980 --> 00:04:33.022
We look at the moon.

71
00:04:33.022 --> 00:04:35.441
We understand the fundamentals
of how planets work

72
00:04:35.692 --> 00:04:39.028
and then apply those rules
to other objects in the solar system.

73
00:04:39.028 --> 00:04:42.282
So the moon is really this incredible
Rosetta Stone for understanding

74
00:04:42.532 --> 00:04:43.700
how planets work.

75
00:04:43.700 --> 00:04:47.495
And so when we look at other objects
around other stars, our understanding

76
00:04:47.495 --> 00:04:49.122
of what we think is happening there

77
00:04:49.122 --> 00:04:51.958
in large part is informed
in our understanding of how the moon

78
00:04:52.208 --> 00:04:54.961
formed and evolved over four
and a half billion years.

79
00:05:03.511 --> 00:05:07.181
To me, the most surprising thing
that we've learned from the LRO spacecraft

80
00:05:07.181 --> 00:05:10.518
in its 13 year mission to the moon
is that we were able to see

81
00:05:10.518 --> 00:05:13.271
the moon change underneath our feet.

82
00:05:13.563 --> 00:05:17.442
We've identified new impact craters
that have formed in the last 13 years.

83
00:05:17.442 --> 00:05:18.693
We're seeing surface changes.

84
00:05:18.693 --> 00:05:21.029
We're seeing the presence
of volatiles, water

85
00:05:21.029 --> 00:05:23.156
at the surface of the moon
and how it moves around

86
00:05:23.364 --> 00:05:26.534
as a function of the time of day
on the surface of the moon.

87
00:05:26.784 --> 00:05:29.579
We've really taken the moon from being
what was once thought to be

88
00:05:29.579 --> 00:05:33.166
a sort of a static, unchanging world
and are now actually able

89
00:05:33.374 --> 00:05:37.086
to measure changes on the lunar surface,
the dynamics of the moon,

90
00:05:37.253 --> 00:05:40.089
and how it evolves,
not over millions or billions of years,

91
00:05:40.089 --> 00:05:43.634
but over the span of a human
lifetime of several years.

92
00:05:43.676 --> 00:05:47.013
And so we've taken the moon
from being this ancient object

93
00:05:47.013 --> 00:05:50.224
and really showing how compelling
and how dynamic it is.

94
00:05:50.475 --> 00:05:54.103
And again, all with the lens of
how do we prepare to send future

95
00:05:54.103 --> 00:05:58.066
explorers, both crew and robotic
explorers, to the surface of the moon,

96
00:05:58.358 --> 00:06:03.071
to take the lessons that we've learned
from orbit and apply them to the surface?

97
00:06:03.321 --> 00:06:07.909
So this next era of lunar exploration
is very exciting, but it's informed

98
00:06:07.909 --> 00:06:10.953
in large part of the discoveries
that we've made over the last 13 years.

99
00:06:19.545 --> 00:06:20.713
We have a number of

100
00:06:20.713 --> 00:06:23.758
important science questions of things
that we want to learn about the moon.

101
00:06:23.758 --> 00:06:27.095
We're still arguing among ourselves,
the scientific community,

102
00:06:27.095 --> 00:06:29.138
about how the moon formed,
how old the moon is.

103
00:06:29.430 --> 00:06:32.392
We think we have a good understanding
of that, in large part

104
00:06:32.392 --> 00:06:34.644
because of the samples
that were brought back by Apollo.

105
00:06:34.811 --> 00:06:35.895
But what Artemis will do in

106
00:06:35.895 --> 00:06:39.524
exploring the South Pole of the moon,
a completely new frontier of the lunar

107
00:06:39.524 --> 00:06:43.027
surface, is inform those models,
those hypotheses

108
00:06:43.027 --> 00:06:46.489
that we have, and ultimately
potentially challenge those hypotheses.

109
00:06:46.489 --> 00:06:49.242
We may find out the moon is older
than we think it is.

110
00:06:49.242 --> 00:06:50.785
The places that we want to go at the South

111
00:06:50.785 --> 00:06:52.787
Pole are going to be
some of the oldest surfaces

112
00:06:52.787 --> 00:06:54.288
that we've ever explored on

113
00:06:54.288 --> 00:06:57.458
any planetary body,
whether it's with humans or with robots.

114
00:06:57.458 --> 00:07:01.212
And so those first explorers
will be peering back in time

115
00:07:01.212 --> 00:07:03.840
to the very earliest history of the moon.

116
00:07:04.215 --> 00:07:07.969
We'd also like to know
what what the volatiles that we've mapped

117
00:07:07.969 --> 00:07:11.055
from orbit, the water that we see
from orbit, what is it like?

118
00:07:11.806 --> 00:07:12.765
How much is there?

119
00:07:12.765 --> 00:07:16.936
And so these very first missions
to the surface of the moon, to the South

120
00:07:16.936 --> 00:07:19.272
Pole are going to really be telling us
something fundamental

121
00:07:19.272 --> 00:07:23.401
about the age of the moon , as well
as how much water might be present there.

122
00:07:23.568 --> 00:07:27.155
And that water becomes a valuable resource
that we could potentially use in

123
00:07:27.155 --> 00:07:31.117
future exploration of the moon to sustain
a long term presence at the moon.

124
00:07:31.117 --> 00:07:34.954
And so the fundamental questions
of how the moon formed its age

125
00:07:35.121 --> 00:07:38.416
and how this precious water
actually got to the surface of the moon,

126
00:07:38.416 --> 00:07:40.126
are some of the key questions
that we'll be asking.

127
00:07:48.342 --> 00:07:50.595
If you're interested in learning more
about this eclipse

128
00:07:50.595 --> 00:07:52.472
and what we have learned
about the moon in general,

129
00:07:52.472 --> 00:07:57.143
I would suggest people go to the website
moon dot nasa.gov and really dive

130
00:07:57.143 --> 00:08:00.855
into everything we've learned, everything
that we are learning about the moon.

131
00:08:01.481 --> 00:08:04.233
To help you understand
how to take pictures of the moon.

132
00:08:04.275 --> 00:08:05.735
We have a number of resources there

133
00:08:05.735 --> 00:08:09.405
for four lunar observers over the weekend
and during the eclipse.

134
00:08:09.447 --> 00:08:13.451
I would encourage people to tune in
to our NASA's broadcast of the Eclipse.

135
00:08:13.784 --> 00:08:17.538
Go to nasa.gov, slash live
and you'll get treated to

136
00:08:17.663 --> 00:08:21.292
a wonderful sharing
of the lunar eclipse around the world.

137
00:08:21.334 --> 00:08:24.253
If it's cloudy where you are,
you can tune in and still enjoy it

138
00:08:24.504 --> 00:08:25.671
from the comfort of your own home.

139
00:08:33.638 --> 00:08:35.306
The Lunar Reconnaissance
Orbiter was launched

140
00:08:35.306 --> 00:08:38.851
in 2009 for what was supposed to be a
1 to 2 year mission.

141
00:08:39.477 --> 00:08:43.523
We recently learned that we've been given
a three year extension to our mission,

142
00:08:43.523 --> 00:08:46.943
which will take our operations out
until 2025, at least.

143
00:08:46.943 --> 00:08:49.820
And so what we've done is
take this 1 to 2 year mission

144
00:08:50.029 --> 00:08:53.115
and turn it into now a decade
plus long mission.

145
00:08:53.407 --> 00:08:56.619
This June, we'll be celebrating 13 years
of orbiting the moon.

146
00:08:56.869 --> 00:08:59.622
And in that time, we've discovered
new impact craters.

147
00:08:59.622 --> 00:09:02.041
We've found that the moon is

148
00:09:03.125 --> 00:09:05.586
changing in ways
that we had never expected before.

149
00:09:05.586 --> 00:09:09.799
We're actually able to see the surface
change very slowly underneath our feet.

150
00:09:10.216 --> 00:09:13.511
We're able to measure the presence
of water on the surface of the moon.

151
00:09:13.511 --> 00:09:16.722
And so over the next several years,
we're going to be looking at the presence,

152
00:09:16.764 --> 00:09:20.184
abundance of water in places
near the south pole of the moon, places

153
00:09:20.184 --> 00:09:23.854
that we hope to explore
with future human and robotic explorers.

154
00:09:24.188 --> 00:09:26.774
We're also looking at the volcanic
and impact history of the moon,

155
00:09:26.774 --> 00:09:30.611
the fundamental geologic evolution
of the object over billions of years.

156
00:09:30.611 --> 00:09:33.948
And so the next three years of LRO
data is going to really

157
00:09:34.740 --> 00:09:37.660
reveal some of the additional mysteries
about the moon and set us up

158
00:09:37.660 --> 00:09:40.746
for the next decade
and beyond of lunar explorations

159
00:09:40.746 --> 00:09:43.833
with both human and robotic explorers
going to the surface of the moon.
