<v Speaker 1>of the universe as you drift off into a peaceful

6
00:00:22.480 --> 00:00:29.480
<v Speaker 1>slumber under the night sky. PLATO mission unveiling new worlds

7
00:00:29.519 --> 00:00:37.280
<v Speaker 1>beyond Earth. The PLATO Planetary Transits and Oscillations of Stars

8
00:00:37.799 --> 00:00:42.320
<v Speaker 1>mission is one of the European Space Agencies esa most

9
00:00:42.359 --> 00:00:46.719
<v Speaker 1>ambitious and exciting endeavors in the field of exoplanet research.

10
00:00:48.799 --> 00:00:52.560
<v Speaker 1>Scheduled for launch in twenty twenty six, PLATO aims to

11
00:00:52.600 --> 00:00:55.960
<v Speaker 1>address some of the most profound questions about our universe.

12
00:00:56.439 --> 00:01:00.960
<v Speaker 1>Are there other habitable worlds like Earth? What are the

13
00:01:01.000 --> 00:01:06.239
<v Speaker 1>conditions necessary for life? How common are planets in our

14
00:01:06.280 --> 00:01:12.159
<v Speaker 1>galaxy that could support life. To answer these questions, PLATO

15
00:01:12.239 --> 00:01:15.959
<v Speaker 1>will utilize a suite of twenty six telescopes and cameras

16
00:01:16.000 --> 00:01:19.439
<v Speaker 1>to search for exoplanets and study their host stars with

17
00:01:19.640 --> 00:01:25.680
<v Speaker 1>unprecedented precision. The primary objective of the PLATO mission is

18
00:01:25.719 --> 00:01:30.840
<v Speaker 1>to detect and characterize exoplanets particularly those in the habitable

19
00:01:30.959 --> 00:01:34.359
<v Speaker 1>zone of their parent stars, the region around a star

20
00:01:34.439 --> 00:01:38.079
<v Speaker 1>where conditions could be suitable for liquid water to exist

21
00:01:38.159 --> 00:01:44.359
<v Speaker 1>on a planet's surface. Unlike many previous missions, PLATO is

22
00:01:44.400 --> 00:01:48.000
<v Speaker 1>designed to find Earth sized and super Earth sized planets

23
00:01:48.159 --> 00:01:53.920
<v Speaker 1>orbiting some like stars. These planets are of particular interest

24
00:01:54.079 --> 00:01:57.120
<v Speaker 1>because they are the most likely candidates to host life

25
00:01:57.120 --> 00:02:02.319
<v Speaker 1>as we know. It will also focus on bright stars,

26
00:02:02.719 --> 00:02:07.000
<v Speaker 1>which allows for follow up observations with ground based telescopes

27
00:02:07.040 --> 00:02:13.319
<v Speaker 1>to confirm and further study the discovered exoplanets. One of

28
00:02:13.360 --> 00:02:17.000
<v Speaker 1>the key techniques PLATO will use to find exoplanets is

29
00:02:17.039 --> 00:02:22.800
<v Speaker 1>the transit method. This method involves monitoring the brightness of

30
00:02:22.879 --> 00:02:26.879
<v Speaker 1>stars over time and looking for periodic dimming that occurs

31
00:02:26.919 --> 00:02:30.879
<v Speaker 1>when a planet passes or transits in front of its

32
00:02:30.879 --> 00:02:35.639
<v Speaker 1>host star. By measuring the amount of dimming and the

33
00:02:35.719 --> 00:02:39.759
<v Speaker 1>duration of the transit, scientists can determine the size of

34
00:02:39.800 --> 00:02:45.120
<v Speaker 1>the planet and its orbital period. But transit method is

35
00:02:45.199 --> 00:02:49.039
<v Speaker 1>particularly powerful because it not only reveals the presence of

36
00:02:49.080 --> 00:02:53.319
<v Speaker 1>a planet, but also provides information about its size and orbit,

37
00:02:53.680 --> 00:02:59.719
<v Speaker 1>which are crucial for assessing its potential habitability. Plato's array

38
00:02:59.759 --> 00:03:02.599
<v Speaker 1>of time telescopes will allow it to monitor a large

39
00:03:02.719 --> 00:03:08.800
<v Speaker 1>number of stars, simultaneously increasing the chances of detecting transiting planets.

40
00:03:10.719 --> 00:03:14.960
<v Speaker 1>The mission will target relatively bright stars, making it easier

41
00:03:15.000 --> 00:03:20.680
<v Speaker 1>to perform follow up observations from the ground. This multi

42
00:03:20.719 --> 00:03:25.000
<v Speaker 1>telescope approach is innovative and enhances the mission's ability to

43
00:03:25.080 --> 00:03:29.120
<v Speaker 1>detect smaller Earth sized planets that are more challenging to

44
00:03:29.199 --> 00:03:35.000
<v Speaker 1>find than larger gas giants. Each of Plato's telescopes will

45
00:03:35.039 --> 00:03:38.800
<v Speaker 1>observe the same field of view, combining their light gathering

46
00:03:38.879 --> 00:03:42.080
<v Speaker 1>power to achieve the high precision needed to detect the

47
00:03:42.199 --> 00:03:48.240
<v Speaker 1>tiny dimming caused by Earth sized planets. In addition to

48
00:03:48.319 --> 00:03:52.960
<v Speaker 1>finding exoplanets, Plato will also study the host stars themselves

49
00:03:53.039 --> 00:04:01.360
<v Speaker 1>through a technique known as asteroseismology. Asteroseismology involves measuring oscillations

50
00:04:01.560 --> 00:04:07.479
<v Speaker 1>or starquakes on the surface of stars. These oscillations cause

51
00:04:07.599 --> 00:04:11.039
<v Speaker 1>variations in the star's brightness that can be detected by

52
00:04:11.039 --> 00:04:18.600
<v Speaker 1>Plato's sensitive instruments. By analyzing these variations, scientists can gain

53
00:04:18.720 --> 00:04:25.079
<v Speaker 1>detailed information about the star's internal structure, composition, and evolutionary state.

54
00:04:27.000 --> 00:04:30.600
<v Speaker 1>This information is crucial for understanding the properties of the

55
00:04:30.639 --> 00:04:35.759
<v Speaker 1>exoplanets orbiting these stars because of planet's characteristics are closely

56
00:04:35.839 --> 00:04:40.519
<v Speaker 1>linked to those of its host star. The combination of

57
00:04:40.600 --> 00:04:45.720
<v Speaker 1>exoplanet detection and astero seismology makes PLATO a powerful tool

58
00:04:45.879 --> 00:04:52.560
<v Speaker 1>for studying planetary systems in great detail. By characterizing both

59
00:04:52.600 --> 00:04:56.199
<v Speaker 1>the planets and their host stars, PLATO will provide a

60
00:04:56.279 --> 00:05:00.639
<v Speaker 1>comprehensive picture of these systems, helping to identify those that

61
00:05:00.680 --> 00:05:06.519
<v Speaker 1>are most similar to our own Solar system. This, in turn,

62
00:05:07.000 --> 00:05:10.680
<v Speaker 1>will inform our understanding of how common Earth like planets

63
00:05:10.720 --> 00:05:13.720
<v Speaker 1>are in the galaxy and the likelihood of finding other

64
00:05:13.800 --> 00:05:20.759
<v Speaker 1>habitable worlds. Plato's mission design includes a planned operational lifetime

65
00:05:20.839 --> 00:05:24.839
<v Speaker 1>of at least four years, with the possibility of extensions

66
00:05:24.879 --> 00:05:28.199
<v Speaker 1>depending on its success and the health of the spacecraft.

67
00:05:30.160 --> 00:05:33.800
<v Speaker 1>During this time, PLATO will serve a two main regions

68
00:05:33.800 --> 00:05:37.040
<v Speaker 1>of the sky, a long duration field and a step

69
00:05:37.079 --> 00:05:43.160
<v Speaker 1>aanstair field. The long duration field will be observed continuously

70
00:05:43.319 --> 00:05:47.360
<v Speaker 1>for two to three years, allowing PLATO to detect planets

71
00:05:47.399 --> 00:05:51.639
<v Speaker 1>with longer orbital periods, including those in the habitable zone

72
00:05:51.680 --> 00:05:57.480
<v Speaker 1>of some like stars. The stepananstair field will involve shorter

73
00:05:57.600 --> 00:06:01.800
<v Speaker 1>observations of different regions of the sky, providing a broader

74
00:06:01.879 --> 00:06:06.199
<v Speaker 1>survey of stellar populations and increasing the overall number of

75
00:06:06.279 --> 00:06:12.959
<v Speaker 1>stars observed. One of the significant advantages of Plato's approach

76
00:06:13.160 --> 00:06:16.279
<v Speaker 1>is its ability to detect and study planets in a

77
00:06:16.360 --> 00:06:22.519
<v Speaker 1>variety of stellar environments. By observing different regions of the sky,

78
00:06:23.040 --> 00:06:27.560
<v Speaker 1>Plato will sample stars with a wide range of ages, compositions,

79
00:06:27.959 --> 00:06:34.519
<v Speaker 1>and masses. This diversity will help scientists understand how planetary

80
00:06:34.639 --> 00:06:38.399
<v Speaker 1>systems form and evolve over time, and how different stellar

81
00:06:38.519 --> 00:06:43.000
<v Speaker 1>environments influence the likelihood of planet formation and the potential

82
00:06:43.079 --> 00:06:48.680
<v Speaker 1>for habitability. Plato's data will be invaluable for follow up

83
00:06:48.720 --> 00:06:55.319
<v Speaker 1>studies with other space based and ground based observatories. For instance,

84
00:06:55.800 --> 00:06:59.920
<v Speaker 1>once a planet candidate is identified by Plato, its hosts

85
00:07:00.399 --> 00:07:04.160
<v Speaker 1>can be observed with radial velocity instruments to confirm the

86
00:07:04.199 --> 00:07:10.240
<v Speaker 1>planet's existence and measure its mass. The combination of transit

87
00:07:10.360 --> 00:07:14.079
<v Speaker 1>and radial velocity data will provide a complete picture of

88
00:07:14.120 --> 00:07:19.759
<v Speaker 1>the planet size, mass, and density, allowing scientists to infer

89
00:07:19.800 --> 00:07:26.959
<v Speaker 1>its composition and internal structure. This detailed characterization is essential

90
00:07:27.040 --> 00:07:34.279
<v Speaker 1>for assessing the planet's potential habitability. Moreover, Plato's discoveries will

91
00:07:34.319 --> 00:07:39.360
<v Speaker 1>be prime targets for future missions designed to study exoplanet atmospheres,

92
00:07:39.879 --> 00:07:44.800
<v Speaker 1>such as the James Web Space Telescope JWST and the

93
00:07:44.879 --> 00:07:52.639
<v Speaker 1>Atmospheric Remote Sensing Infrared Exoplanet Large Survey AERIAL. By analyzing

94
00:07:52.680 --> 00:07:56.560
<v Speaker 1>the light that passes through a planet's atmosphere during a transit,

95
00:07:56.959 --> 00:08:00.720
<v Speaker 1>these telescopes can identify the chemical compoty position of the

96
00:08:00.800 --> 00:08:06.160
<v Speaker 1>atmosphere and search for signs of habitability or even biosignatures

97
00:08:06.160 --> 00:08:12.279
<v Speaker 1>indicators of life. Plato's role in identifying the best targets

98
00:08:12.279 --> 00:08:16.000
<v Speaker 1>for these follow up observations will be critical for advancing

99
00:08:16.040 --> 00:08:22.319
<v Speaker 1>our search for life beyond Earth. The PLATO mission represents

100
00:08:22.360 --> 00:08:25.519
<v Speaker 1>a significant leap forward in our ability to find and

101
00:08:25.639 --> 00:08:32.600
<v Speaker 1>study exoplanets. Its innovative design and advanced technology will enable

102
00:08:32.639 --> 00:08:36.639
<v Speaker 1>it to detect smaller planets and characterize their host stars

103
00:08:36.720 --> 00:08:42.799
<v Speaker 1>with unprecedented precision. The missions focus on bright stars and

104
00:08:42.879 --> 00:08:47.000
<v Speaker 1>earthlike planets makes it particularly exciting for the search for

105
00:08:47.120 --> 00:08:53.879
<v Speaker 1>habitable worlds. By expanding our knowledge of exoplanets and their environments,

106
00:08:54.279 --> 00:08:58.159
<v Speaker 1>PLATO will help answer fundamental questions about the prevalence of

107
00:08:58.240 --> 00:09:02.000
<v Speaker 1>habitable planets in our galley and the potential for life

108
00:09:02.039 --> 00:09:07.639
<v Speaker 1>elsewhere in the universe. The scientific community and the general

109
00:09:07.720 --> 00:09:13.399
<v Speaker 1>public eagerly anticipate the launch of the PLATO mission. Its

110
00:09:13.480 --> 00:09:17.720
<v Speaker 1>discoveries have the potential to transform our understanding of planetary

111
00:09:17.799 --> 00:09:24.279
<v Speaker 1>systems and the conditions necessary for life. The mission's contributions

112
00:09:24.320 --> 00:09:28.600
<v Speaker 1>to exoplanet science will be profound, laying the groundwork for

113
00:09:28.679 --> 00:09:32.679
<v Speaker 1>future explorations and potentially leading to one of the most

114
00:09:32.720 --> 00:09:37.799
<v Speaker 1>significant discoveries in human history, the detection of life beyond Earth.

115
00:09:39.720 --> 00:09:44.559
<v Speaker 1>In conclusion, the platomission embodies the spirit of exploration and

116
00:09:44.639 --> 00:09:48.759
<v Speaker 1>discovery that drives humanity's quest to understand our place in

117
00:09:48.840 --> 00:09:55.000
<v Speaker 1>the universe. Through its innovative approach to exoplanet detection and

118
00:09:55.080 --> 00:10:00.840
<v Speaker 1>stellar characterization, PLATO will provide unprecedented insights into the diversity

119
00:10:00.960 --> 00:10:06.759
<v Speaker 1>and properties of planetary systems. The missions focus on Earth

120
00:10:06.960 --> 00:10:11.519
<v Speaker 1>like planets and habitable zones is particularly compelling as it

121
00:10:11.600 --> 00:10:16.440
<v Speaker 1>brings us closer to finding other worlds that could support life.

122
00:10:17.240 --> 00:10:20.440
<v Speaker 1>As we look to the future, the data and discoveries

123
00:10:20.440 --> 00:10:24.240
<v Speaker 1>from PLATO will guide our efforts in exploring the cosmos

124
00:10:24.279 --> 00:11:44.120
<v Speaker 1>and searching for signs of life beyond our planets. Before
