Eclipse Eve: Totality Returns to Europe
Astronomy Daily · S05E164 “Eclipse Eve” · Tuesday 11 August 2026. Sources are primary/agency where possible; aggregator dates were checked against originals. In this episode • LEAD — The 12 August total solar eclipse: the only total eclipse of 2026 and the first over mainland Europe since 1999. Totality arcs from Siberia over the North Pole to eastern Greenland, western Iceland, northern Spain and a sliver of Portugal; maximum totality ~2 min 18 s. Partial for much of North America near sunset; not visible from Australia. ESA livestreams from the Javalambre Observatory, Spain. • MIDDLE 1 — A state CASC Long March 7A exploded ~85 seconds after lifting off from Wenchang on 10 August, a total loss (payload reported as the Zhongxing-4B communications satellite). Separately, Landspace’s private Zhuque-3 was on the same-night manifest from Jiuquan for its second propulsive landing-legs recovery attempt — outcome unconfirmed at recording. China’s first orbital-booster landing (net-capture, Long March 10B) already succeeded on 10 July. • MIDDLE 2 — The Perseids peak overnight 12–13 August under a New Moon — the darkest conditions in roughly two decades. Parent comet 109P/Swift-Tuttle. Realistic ~30–50 meteors/hr from dark sites (nominal ~100), with a slim chance of a dust-trail boost; the next confidently forecast outburst is 2028. • MIDDLE 3 — Japan’s H3 launched Michibiki No. 7 (QZS-7) from Tanegashima, bringing the Quasi-Zenith Satellite System up to the strength Japan needs to run it as a standalone service — a regional navigation layer that keeps a satellite near the zenith over Japan/Asia-Pacific, reinforcing GPS and building navigation resilience. The satellite also hosts a US Space Force space-surveillance sensor (SACHI). • CLOSER — Both-hemispheres skywatch: eclipse viewing times (totality window ~16:58–18:34 UT, greatest ~17:46 UT) and the ISO 12312-2 eye-safety rule; Perseid how-to for the North (best 2 a.m.–dawn); and Southern-Hemisphere content — pre-dawn planets, evening Venus, Comet 10P/Tempel 2. Eye safety • A partial eclipse is never safe to view with the naked eye. Use ISO 12312-2 certified eclipse glasses/viewers, or indirect projection (pinhole). Direct viewing is only safe during true totality, and only inside the path (Greenland, Iceland, Spain).

00:00:00.560 --> 00:00:02.800
Anna: Good day and welcome to Astronomy
1
00:00:02.800 --> 00:00:04.320
AstroDailyPod. I'm Anna.
2
00:00:04.400 --> 00:00:07.040
Avery: And I'm Avery. And if you only listen to us
3
00:00:07.040 --> 00:00:08.760
once this year, make it the next
4
00:00:08.760 --> 00:00:11.480
Anna: two days, because tomorrow, the 12th of
5
00:00:11.480 --> 00:00:14.080
August, the moon does something it hasn't
6
00:00:14.080 --> 00:00:16.000
done over mainland Europe since
7
00:00:16.079 --> 00:00:18.320
1999. It slides
8
00:00:18.400 --> 00:00:21.320
completely in front of the sun, the one and
9
00:00:21.320 --> 00:00:23.520
only total solar eclipse of
10
00:00:23.520 --> 00:00:24.560
2026.
11
00:00:24.960 --> 00:00:27.640
Avery: And then, once the sun goes down, the same
12
00:00:27.640 --> 00:00:29.520
new Moon that made that eclipse possible
13
00:00:29.760 --> 00:00:32.500
steps out of the way entirely. Hands us the
14
00:00:32.500 --> 00:00:35.060
darkest Perseid meteor peak in about 20
15
00:00:35.060 --> 00:00:35.420
years.
16
00:00:35.980 --> 00:00:38.540
Anna: One new moon, two headline events
17
00:00:38.620 --> 00:00:41.540
roughly 24 hours apart. We'll set the
18
00:00:41.540 --> 00:00:44.020
whole thing up for you. Northern and southern
19
00:00:44.020 --> 00:00:45.860
skies both, Plus a
20
00:00:45.860 --> 00:00:48.110
Avery: rough morning for one Chinese rocket, a, uh,
21
00:00:48.179 --> 00:00:50.140
quieter question mark hanging over another,
22
00:00:50.380 --> 00:00:52.820
and Japan quietly finishing off its own
23
00:00:52.820 --> 00:00:54.940
answer to gps. Let's get into it.
24
00:00:55.260 --> 00:00:57.980
Anna: So let's talk about tomorrow properly,
25
00:00:58.220 --> 00:01:00.970
because this is a genuinely rare one. Uh, a
26
00:01:00.970 --> 00:01:03.650
total solar eclipse happens somewhere on
27
00:01:03.650 --> 00:01:06.650
Earth roughly 18 months or so. But the
28
00:01:06.650 --> 00:01:09.530
last time totality touched down anywhere on
29
00:01:09.530 --> 00:01:12.410
the planet was April 2024 over
30
00:01:12.410 --> 00:01:15.130
North America. That's more than two years
31
00:01:15.130 --> 00:01:17.650
ago. Tomorrow ends that drought,
32
00:01:18.050 --> 00:01:20.610
and the geography of this one is strange and
33
00:01:20.610 --> 00:01:23.370
beautiful. Most total eclipses
34
00:01:23.370 --> 00:01:26.330
race roughly west to east across the middle
35
00:01:26.330 --> 00:01:29.330
of the globe. This one goes over the top of
36
00:01:29.330 --> 00:01:32.210
the world. The Moon's shadow first touches
37
00:01:32.210 --> 00:01:34.970
down in the far north of Siberia, then
38
00:01:35.050 --> 00:01:37.850
arcs up and over the North Pole, drops
39
00:01:37.850 --> 00:01:40.730
down onto eastern Greenland, crosses the west
40
00:01:40.730 --> 00:01:43.369
coast of Iceland, including Reykjavik,
41
00:01:43.530 --> 00:01:46.530
and finishes across northern Spain and just
42
00:01:46.530 --> 00:01:49.210
clips the northwestern corner of Portugal.
43
00:01:49.530 --> 00:01:52.330
Totality itself is brief. At most
44
00:01:52.330 --> 00:01:55.250
about 2 minutes and 18 seconds right on
45
00:01:55.250 --> 00:01:57.790
the centre line. Blink and you miss it by
46
00:01:57.790 --> 00:02:00.630
eclipse standards. But the setting more than
47
00:02:00.630 --> 00:02:03.430
makes up for it, because in Spain, the sun
48
00:02:03.430 --> 00:02:06.150
is hanging low in the west, close to the
49
00:02:06.150 --> 00:02:09.030
horizon. In the last light before sunset,
50
00:02:09.350 --> 00:02:12.309
imagine the sun's corona flaring out over
51
00:02:12.309 --> 00:02:15.190
a Spanish skyline at dusk. That's
52
00:02:15.190 --> 00:02:17.390
the image people have been planning trips
53
00:02:17.390 --> 00:02:20.310
around for years now before anyone
54
00:02:20.310 --> 00:02:22.430
in the Southern Hemisphere gets their hopes
55
00:02:22.430 --> 00:02:24.950
up. Let me be straight with you, because we
56
00:02:24.950 --> 00:02:27.670
always are on this show. This eclipse is a
57
00:02:27.670 --> 00:02:30.070
Northern Hemisphere event full stop.
58
00:02:30.390 --> 00:02:32.790
Totality is only over Greenland,
59
00:02:32.870 --> 00:02:35.630
Iceland, northern Spain and that little bit
60
00:02:35.630 --> 00:02:38.590
of Portugal. A much wider slice of the world
61
00:02:38.590 --> 00:02:40.830
gets a partial eclipse. Parts of North
62
00:02:40.830 --> 00:02:43.670
America, especially eastern Canada and
63
00:02:43.670 --> 00:02:46.190
the northeastern United States, will see the
64
00:02:46.190 --> 00:02:49.190
sun take a bite low in the sky near sunset.
65
00:02:49.350 --> 00:02:52.190
But here in Australia, we see nothing at
66
00:02:52.190 --> 00:02:54.950
all. So southern listeners, stay with us.
67
00:02:55.110 --> 00:02:57.550
Your night is coming later in the show, and
68
00:02:57.550 --> 00:02:58.470
it's a good one.
69
00:02:58.790 --> 00:03:01.670
Here's the scale that gets me though, add up
70
00:03:01.670 --> 00:03:04.470
everyone who falls under at least a partial
71
00:03:04.470 --> 00:03:07.270
shadow tomorrow across Europe, North Africa,
72
00:03:07.510 --> 00:03:10.230
northern Asia and much of North America.
73
00:03:10.310 --> 00:03:12.390
And you're talking on the order of, um, a
74
00:03:12.390 --> 00:03:15.110
billion people who can in principle
75
00:03:15.350 --> 00:03:18.310
look up and see the moon and sun overlap.
76
00:03:18.830 --> 00:03:21.710
One event, a billion potential witnesses.
77
00:03:21.950 --> 00:03:24.670
And it's not just a spectacle, it's a working
78
00:03:24.670 --> 00:03:27.350
day for scientists. Those couple of minutes
79
00:03:27.350 --> 00:03:30.070
of totality are one of the only times we can
80
00:03:30.070 --> 00:03:32.990
study the sun's corona, that faint outer
81
00:03:32.990 --> 00:03:35.230
atmosphere directly from the ground.
82
00:03:35.710 --> 00:03:38.310
Space agencies and observatories along the
83
00:03:38.310 --> 00:03:40.950
track are gearing up. The European Space
84
00:03:40.950 --> 00:03:43.470
Agency, for instance, is running a live
85
00:03:43.470 --> 00:03:46.030
broadcast from the Havalambra Observatory in
86
00:03:46.030 --> 00:03:48.820
Spain, stitching together telescope feeds and
87
00:03:48.820 --> 00:03:51.260
drone footage so that even if you're nowhere
88
00:03:51.260 --> 00:03:54.060
near the path, you can watch totality as it
89
00:03:54.060 --> 00:03:56.740
happens. The ever reality is the
90
00:03:56.740 --> 00:03:59.100
weather, of course. It always is with
91
00:03:59.100 --> 00:04:02.020
eclipses. Greenland is remote and cold,
92
00:04:02.100 --> 00:04:04.660
but the air coming off the ice sheet actually
93
00:04:04.660 --> 00:04:07.540
tends to clear the skies, so the odds there
94
00:04:07.540 --> 00:04:10.540
aren't bad. Iceland is Iceland. It
95
00:04:10.540 --> 00:04:12.900
could be crystal clear or socked in with
96
00:04:12.900 --> 00:04:15.320
cloud, sometimes within the same hour.
97
00:04:15.640 --> 00:04:18.320
And Spain has the best of both worlds for
98
00:04:18.320 --> 00:04:21.320
most travellers. Reliable late summer skies
99
00:04:21.480 --> 00:04:24.360
and the roads, airports and towns to actually
100
00:04:24.440 --> 00:04:27.440
get people into the path. That's why the bulk
101
00:04:27.440 --> 00:04:30.000
of eclipse chasers are converging on Spain
102
00:04:30.000 --> 00:04:32.960
and Iceland tonight, watching forecasts
103
00:04:32.960 --> 00:04:35.680
like hawks. We'll give you the exact viewing
104
00:04:35.680 --> 00:04:38.440
times for the path and for North America, um,
105
00:04:38.440 --> 00:04:41.170
in the sky watch at the end. For now, the
106
00:04:41.170 --> 00:04:44.010
headline is simply, After 27
107
00:04:44.010 --> 00:04:46.850
years, totality is coming home to Europe.
108
00:04:47.170 --> 00:04:49.250
And whatever the sky is doing where you are
109
00:04:49.250 --> 00:04:52.130
tomorrow. It is worth a look, it really
110
00:04:52.130 --> 00:04:52.450
is.
111
00:04:52.930 --> 00:04:55.410
Avery: And from something rising to something that
112
00:04:55.410 --> 00:04:56.530
came down the hard way.
113
00:04:57.010 --> 00:04:59.650
So yesterday was by any measure an
114
00:04:59.650 --> 00:05:02.530
extraordinary day for launches. Four flights
115
00:05:02.530 --> 00:05:05.490
across three countries inside about 12 hours.
116
00:05:06.210 --> 00:05:08.450
And China opened it with a hard one to watch
117
00:05:08.930 --> 00:05:11.810
along March 7 a. That's a state rocket
118
00:05:11.810 --> 00:05:14.130
from the big state contractor cask,
119
00:05:14.370 --> 00:05:16.690
lifted off from the Wenchang launch site on
120
00:05:16.690 --> 00:05:19.690
the island of Hainan. And about 85 seconds
121
00:05:19.690 --> 00:05:22.009
into the flight, still climbing, still on
122
00:05:22.009 --> 00:05:24.690
that first main burn, it exploded.
123
00:05:24.930 --> 00:05:27.890
A large fireball, a cloud of debris, and
124
00:05:27.890 --> 00:05:30.650
effectively a total loss of the vehicle and
125
00:05:30.650 --> 00:05:33.610
its payload. The payload was reported to be
126
00:05:33.610 --> 00:05:36.450
a communications satellite, Zhongsheng 4B,
127
00:05:36.770 --> 00:05:39.410
heading for a high orbit China. Space
128
00:05:39.490 --> 00:05:41.410
authorities hadn't put out a detailed
129
00:05:41.410 --> 00:05:43.610
statement as of our recording, so we're
130
00:05:43.610 --> 00:05:46.050
holding the payload detail lightly. But the
131
00:05:46.050 --> 00:05:48.930
outcome itself isn't in doubt. The rocket was
132
00:05:48.930 --> 00:05:51.930
lost. There's a bit of history here too. This
133
00:05:51.930 --> 00:05:54.770
was the 18th flight of the long March 7th A
134
00:05:55.010 --> 00:05:57.610
and awkwardly, the very first one back in
135
00:05:57.610 --> 00:05:59.890
2020 also ended in failure.
136
00:06:00.500 --> 00:06:02.660
So this is a rocket that's flown a lot and
137
00:06:02.660 --> 00:06:05.620
mostly, well, having a very public bad day.
138
00:06:06.180 --> 00:06:08.980
The bigger question is knock on effects. The
139
00:06:08.980 --> 00:06:11.580
long March 7 family is the workhorse that
140
00:06:11.580 --> 00:06:13.980
carries cargo up to China's Tiangong Space
141
00:06:13.980 --> 00:06:16.180
Station. So depending on what the
142
00:06:16.180 --> 00:06:19.060
investigation finds, some upcoming missions
143
00:06:19.060 --> 00:06:21.460
could slip while engineers work out what went
144
00:06:21.460 --> 00:06:24.420
wrong. Now, here's where I want to be careful
145
00:06:24.420 --> 00:06:26.920
because these storeys get tangled. That
146
00:06:26.920 --> 00:06:29.320
failure is one rocket. There was a second
147
00:06:29.560 --> 00:06:31.600
completely separate Chinese launch on the
148
00:06:31.600 --> 00:06:33.720
manifest for the same night, and it's a
149
00:06:33.720 --> 00:06:35.800
storey. We've been following the private
150
00:06:35.800 --> 00:06:38.280
company Landspace and its Zhu K3.
151
00:06:38.840 --> 00:06:41.000
Different company, different launch site.
152
00:06:41.000 --> 00:06:43.760
Jioquan, well over 2000 kilometres from
153
00:06:43.760 --> 00:06:46.280
Wenchang and a very different goal.
154
00:06:46.600 --> 00:06:49.560
Zhu K3 is a reusable stainless steel
155
00:06:49.560 --> 00:06:52.520
methane fueled rocket and last night's flight
156
00:06:52.520 --> 00:06:54.720
was its second attempt to fly to orbit and
157
00:06:54.720 --> 00:06:56.680
then bring its first stage back for a
158
00:06:56.680 --> 00:06:59.620
propulsive landing. Legs touchsc. The Falcon
159
00:06:59.620 --> 00:07:01.980
9 trick. And I want to keep our facts
160
00:07:01.980 --> 00:07:03.700
straight from last week. This would be
161
00:07:03.700 --> 00:07:05.820
China's fourth orbital class recovery
162
00:07:05.820 --> 00:07:08.780
attempt, not its first. China already landed
163
00:07:08.780 --> 00:07:11.180
an orbital booster back in July when a long
164
00:07:11.180 --> 00:07:13.980
3-10-B was caught in a net. What makes
165
00:07:13.980 --> 00:07:16.900
ZK3 different is the method, legs
166
00:07:16.900 --> 00:07:19.180
and engine thrust setting down on a pad
167
00:07:19.180 --> 00:07:21.340
rather than being caught. That's the
168
00:07:21.340 --> 00:07:24.180
milestone Landspace is chasing as we record.
169
00:07:24.420 --> 00:07:27.300
We don't have a confirmed result on that z k3
170
00:07:27.300 --> 00:07:30.140
attempt. And honestly, that's worth a word.
171
00:07:30.220 --> 00:07:33.020
Landspace has form for going quiet. Its
172
00:07:33.020 --> 00:07:35.420
debut flight last year was scrubbed and then
173
00:07:35.420 --> 00:07:38.100
postponed for days with barely a word before
174
00:07:38.100 --> 00:07:41.020
it eventually flew. So the silence tonight
175
00:07:41.020 --> 00:07:43.100
could mean the outcome just hasn't reached
176
00:07:43.100 --> 00:07:45.660
English language press yet. Or it could mean
177
00:07:45.660 --> 00:07:47.900
the flight quietly slipped. We're not going
178
00:07:47.900 --> 00:07:50.060
to guess. When it's confirmed, we'll bring it
179
00:07:50.060 --> 00:07:50.860
to you properly.
180
00:07:51.020 --> 00:07:53.860
Anna: A, uh, rocket lost and another we're still
181
00:07:53.860 --> 00:07:54.540
waiting on.
182
00:07:55.030 --> 00:07:57.630
Meanwhile, the sky above all of it is about
183
00:07:57.630 --> 00:08:00.550
to put on a free show. The Perseids.
184
00:08:01.030 --> 00:08:03.710
Now everyone knows the Perseids. They're the
185
00:08:03.710 --> 00:08:06.390
reliable old friend of the northern summer.
186
00:08:06.470 --> 00:08:09.230
The shower people actually plan barbecues
187
00:08:09.230 --> 00:08:11.310
and camping trips around. But
188
00:08:11.310 --> 00:08:14.150
2026 is special. And I want to
189
00:08:14.150 --> 00:08:16.790
explain why. Because it's a lovely bit of
190
00:08:16.790 --> 00:08:19.590
cosmic coincidence. The peak lands
191
00:08:19.590 --> 00:08:22.310
overnight on the 12th into the 13th,
192
00:08:22.780 --> 00:08:25.660
the same date as the eclipse. And that is
193
00:08:25.660 --> 00:08:28.220
not an accident. A, uh, total solar
194
00:08:28.220 --> 00:08:31.180
eclipse can only happen at New Moon when
195
00:08:31.180 --> 00:08:34.060
The Moon is between us and the Sun. And
196
00:08:34.060 --> 00:08:36.540
this year that new moon falls almost
197
00:08:36.700 --> 00:08:39.700
exactly on the Perseid peak. So
198
00:08:39.700 --> 00:08:42.380
the very thing that darkens the sun by day
199
00:08:42.700 --> 00:08:45.580
leaves the night sky completely moonless.
200
00:08:45.900 --> 00:08:48.540
No moonlight washing out the faint meteors.
201
00:08:49.040 --> 00:08:51.640
It's the best set of conditions the Perseids
202
00:08:51.640 --> 00:08:54.080
have had in roughly two decades.
203
00:08:54.480 --> 00:08:57.240
The meteors themselves are debris from a
204
00:08:57.240 --> 00:08:59.680
comet. Comet 109P,
205
00:08:59.840 --> 00:09:02.200
Swift Tuttle, a big one on a
206
00:09:02.200 --> 00:09:05.080
133 year orbit. Every
207
00:09:05.080 --> 00:09:07.600
August, the Earth ploughs through the trail
208
00:09:07.600 --> 00:09:10.480
of dust it's left behind. And those specks
209
00:09:10.480 --> 00:09:13.280
hit our atmosphere and burn up as shooting
210
00:09:13.280 --> 00:09:16.160
stars. When Swift Tuttle itself last
211
00:09:16.160 --> 00:09:18.520
swung through the inner solar system in the
212
00:09:18.520 --> 00:09:20.980
early 1990s, the Perseids
213
00:09:21.060 --> 00:09:23.980
briefly went berserk. Hundreds of meteors
214
00:09:23.980 --> 00:09:26.860
an hour. The comet's long gone back out
215
00:09:26.860 --> 00:09:29.780
now, so we won't see that this year, in
216
00:09:29.780 --> 00:09:32.580
fact, and I'll be honest, because a moon this
217
00:09:32.580 --> 00:09:35.140
sky can raise expectations. The
218
00:09:35.140 --> 00:09:37.660
forecasters are being measured about the raw
219
00:09:37.660 --> 00:09:40.660
numbers this year. The textbook figure is up
220
00:09:40.660 --> 00:09:43.140
to about a hundred meteors an hour under
221
00:09:43.140 --> 00:09:45.500
perfect conditions. But the meteor
222
00:09:45.500 --> 00:09:48.020
specialists are quietly expecting something
223
00:09:48.020 --> 00:09:50.420
more like 30 to 50 an hour from a
224
00:09:50.420 --> 00:09:52.640
genuinely dark site this time around.
225
00:09:53.280 --> 00:09:55.760
Activity dips a little this year before
226
00:09:55.840 --> 00:09:58.680
picking back up in 2027. There
227
00:09:58.680 --> 00:10:01.280
is one tantalising wildcard, though.
228
00:10:01.600 --> 00:10:04.520
Models suggest the Earth might just clip a
229
00:10:04.520 --> 00:10:07.120
couple of older, narrow dust trails around
230
00:10:07.120 --> 00:10:10.000
the peak one laid down almost a thousand
231
00:10:10.160 --> 00:10:13.160
years ago. If that happens, you could get a
232
00:10:13.160 --> 00:10:15.880
short burst of extra meteors. It's not
233
00:10:15.880 --> 00:10:18.400
guaranteed. The timing has hours of
234
00:10:18.400 --> 00:10:21.280
uncertainty and even the models don't promise
235
00:10:21.280 --> 00:10:24.060
a storm. But it's the kind of maydy that
236
00:10:24.060 --> 00:10:27.060
gets meteor watchers out of bed. The next
237
00:10:27.220 --> 00:10:29.580
genuine outburst that forecasters are
238
00:10:29.580 --> 00:10:32.500
confident about isn't until 2028,
239
00:10:32.660 --> 00:10:35.620
and that one will favour North America. So
240
00:10:35.620 --> 00:10:38.620
the storey of these Perseids isn't really a
241
00:10:38.620 --> 00:10:41.180
hundred an hour. It's the darkest
242
00:10:41.180 --> 00:10:44.060
skies in 20 years. A rare same
243
00:10:44.060 --> 00:10:46.860
day pairing with a total eclipse and a
244
00:10:46.860 --> 00:10:49.490
small chance of a bonus. We'll tell you
245
00:10:49.490 --> 00:10:52.330
exactly when and where to look at the end.
246
00:10:52.570 --> 00:10:55.370
Avery: Love it. And from ancient comet dust to some
247
00:10:55.370 --> 00:10:58.130
very modern hardware. Staying with that busy
248
00:10:58.130 --> 00:11:00.090
launch day, because not all of it was
249
00:11:00.090 --> 00:11:00.810
fireballs.
250
00:11:00.970 --> 00:11:03.970
Over In Japan, an H3 rocket lifted off
251
00:11:03.970 --> 00:11:06.410
from the Tanegashima Space Centre carrying a
252
00:11:06.410 --> 00:11:09.210
hefty navigation satellite. And with it,
253
00:11:09.210 --> 00:11:12.210
Japan took a quietly strategic step. The
254
00:11:12.210 --> 00:11:14.810
satellite is called Michibiki no. 7.
255
00:11:14.890 --> 00:11:17.570
Michibiki, meaning guiding or showing the
256
00:11:17.570 --> 00:11:20.090
way. And it brings Japan's quasi
257
00:11:20.090 --> 00:11:22.810
Zenith satellite system up to full strength.
258
00:11:23.130 --> 00:11:25.130
That's a bit of a mouthful. So here's the
259
00:11:25.130 --> 00:11:27.770
idea. Most of us rely on America's
260
00:11:27.770 --> 00:11:30.490
gps. It's brilliant. But in a place like
261
00:11:30.490 --> 00:11:33.090
Japan, narrow streets, high rise
262
00:11:33.090 --> 00:11:35.610
canyons, steep mountains, GPS
263
00:11:35.690 --> 00:11:38.330
signals can get blocked or bounce around and
264
00:11:38.330 --> 00:11:40.890
throw your position off. Japan's fix is
265
00:11:40.890 --> 00:11:43.810
clever. These quasi zenith satellites fly
266
00:11:43.810 --> 00:11:45.860
in looping orbits that, that keep at least
267
00:11:45.860 --> 00:11:48.860
one of them almost directly overhead, near
268
00:11:48.860 --> 00:11:51.780
the zenith over Japan and the wider Asia
269
00:11:51.780 --> 00:11:54.260
Pacific at all times. A signal coming
270
00:11:54.260 --> 00:11:56.860
straight down is much harder to block than
271
00:11:56.860 --> 00:11:59.700
one coming in low across a skyline. So
272
00:11:59.700 --> 00:12:02.700
Michibiki sharpens and reinforces GPS from
273
00:12:02.700 --> 00:12:05.100
directly above, getting positioning down to
274
00:12:05.100 --> 00:12:07.660
remarkable precision. With this launch,
275
00:12:07.660 --> 00:12:09.980
Japan has the satellites it needs to run that
276
00:12:09.980 --> 00:12:12.300
system as a full standalone service.
277
00:12:12.870 --> 00:12:15.550
And the strategic point is resilience. Japan
278
00:12:15.550 --> 00:12:18.030
now has its own regional backbone that keeps
279
00:12:18.030 --> 00:12:20.670
working even if it can't lean entirely on
280
00:12:20.670 --> 00:12:22.950
someone else's system. In a world where
281
00:12:22.950 --> 00:12:25.510
navigation underpins everything from farming
282
00:12:25.510 --> 00:12:28.070
to shipping to your phone maps, quietly
283
00:12:28.070 --> 00:12:30.950
owning your own overhead layer is a big deal.
284
00:12:31.590 --> 00:12:33.670
And there's a neat little footnote. This
285
00:12:33.670 --> 00:12:36.150
satellite is also carrying a hosted American
286
00:12:36.230 --> 00:12:38.990
payload, a space surveillance camera built
287
00:12:38.990 --> 00:12:41.470
for the US Space force. So, ah, a Japanese
288
00:12:41.470 --> 00:12:44.230
navigation satellite is quietly doubling as a
289
00:12:44.230 --> 00:12:47.070
US space watching sensor. Which tells you how
290
00:12:47.070 --> 00:12:49.310
closely the two allies now work together up
291
00:12:49.310 --> 00:12:52.110
there. Not a fireball, but arguably the most
292
00:12:52.110 --> 00:12:54.230
consequential thing that flew all day.
293
00:12:54.550 --> 00:12:57.390
Anna: From satellites that tell us exactly where we
294
00:12:57.390 --> 00:13:00.310
are to the oldest navigation tool there
295
00:13:00.310 --> 00:13:02.070
is the sky itself.
296
00:13:02.870 --> 00:13:05.510
Let's get you outside. This is the practical
297
00:13:05.510 --> 00:13:07.790
bit and we're doing both hemispheres as
298
00:13:07.790 --> 00:13:10.410
always. Northern friends, you've got the
299
00:13:10.410 --> 00:13:13.010
doubleheader. Southern friends, hang on. Your
300
00:13:13.010 --> 00:13:15.250
turn is coming and it's all yours.
301
00:13:15.890 --> 00:13:18.730
First, the eclipse, the timings. The
302
00:13:18.730 --> 00:13:21.050
moon's shadow sweeps through in the late
303
00:13:21.050 --> 00:13:24.010
afternoon and evening European time in
304
00:13:24.010 --> 00:13:26.930
rough universal time. Totality begins up
305
00:13:26.930 --> 00:13:29.754
in the high Arctic a little before 17
306
00:13:29.866 --> 00:13:32.690
UT, reaches greatest eclipse around
307
00:13:32.770 --> 00:13:35.690
1746 UT and finishes
308
00:13:35.690 --> 00:13:37.970
over Spain and Portugal by about
309
00:13:38.050 --> 00:13:40.890
1834 UT. On the ground,
310
00:13:41.130 --> 00:13:43.890
that means Iceland sees totality in the late
311
00:13:43.890 --> 00:13:46.490
afternoon. Spain sees it in the early
312
00:13:46.490 --> 00:13:48.890
evening with the sun low and close to
313
00:13:48.890 --> 00:13:51.370
setting. North America, you're getting a
314
00:13:51.370 --> 00:13:54.290
partial, not totality, and it's uh, a low
315
00:13:54.290 --> 00:13:56.890
in the sky, near sunset affair for
316
00:13:56.890 --> 00:13:59.770
eastern Canada and the northeastern United
317
00:13:59.850 --> 00:14:02.570
States. The further northeast you are,
318
00:14:02.730 --> 00:14:05.490
the more of a bite you'll see further
319
00:14:05.490 --> 00:14:08.400
west. And it fades out. And now the rule
320
00:14:08.400 --> 00:14:11.080
we never, ever trim. A, uh, partial
321
00:14:11.080 --> 00:14:13.960
eclipse is not safe to look at with the naked
322
00:14:13.960 --> 00:14:16.800
eye, not for a Second, you must
323
00:14:16.800 --> 00:14:19.760
use certified eclipse glasses or viewers
324
00:14:19.840 --> 00:14:21.440
that meet the ISO
325
00:14:21.440 --> 00:14:24.160
123122
326
00:14:24.320 --> 00:14:27.040
safety standard or watch by indirect
327
00:14:27.040 --> 00:14:29.440
projection like a simple pinhole.
328
00:14:29.760 --> 00:14:32.400
Ordinary sunglasses, smoked glass,
329
00:14:32.560 --> 00:14:35.200
phone cameras, none of that protects your
330
00:14:35.200 --> 00:14:38.150
eyes. The only moment it is ever safe
331
00:14:38.150 --> 00:14:41.110
to look directly is during total totality
332
00:14:41.110 --> 00:14:43.750
itself. And that only happens inside
333
00:14:43.830 --> 00:14:46.150
that narrow path in Greenland,
334
00:14:46.310 --> 00:14:49.190
Iceland and Spain. Everywhere else
335
00:14:49.190 --> 00:14:52.069
glass is on the whole time. Please
336
00:14:52.070 --> 00:14:54.790
look after your eyes then after
337
00:14:54.790 --> 00:14:57.310
dark. The Perseids for the Northern
338
00:14:57.310 --> 00:15:00.150
hemisphere the peak is overnight on the 12th
339
00:15:00.150 --> 00:15:02.950
into the 13th and with no moon at all,
340
00:15:03.190 --> 00:15:05.820
conditions are as good as they get. Best
341
00:15:05.820 --> 00:15:08.660
viewing is after midnight from roughly 2am
342
00:15:08.740 --> 00:15:11.540
until dawn when the shower's radiant climbs
343
00:15:11.540 --> 00:15:14.420
high. Get somewhere dark, lie back,
344
00:15:14.420 --> 00:15:17.060
give your eyes 20 minutes to adjust and
345
00:15:17.140 --> 00:15:19.940
don't stare at your phone. Realistically
346
00:15:20.020 --> 00:15:22.740
30 to 50 an hour from a dark sight.
347
00:15:22.900 --> 00:15:25.700
More if that dust trail wildcard comes off
348
00:15:26.180 --> 00:15:29.180
now. Southern hemisphere, this is yours. Two
349
00:15:29.180 --> 00:15:31.980
bits of bad news then the good stuff. You
350
00:15:31.980 --> 00:15:34.820
can't see tomorrow's eclipse and the Perseids
351
00:15:34.820 --> 00:15:37.600
barely clear the horizon for us because their
352
00:15:37.600 --> 00:15:40.480
radiant sits low in the north. So don't
353
00:15:40.480 --> 00:15:43.120
stay up chasing them from Sydney. Instead
354
00:15:43.440 --> 00:15:46.400
look before dawn. The pre dawn eastern
355
00:15:46.400 --> 00:15:49.320
sky right now has a lovely lineup of planets
356
00:15:49.320 --> 00:15:52.160
strung along it. A genuine naked eye treat.
357
00:15:52.400 --> 00:15:55.160
No equipment needed and much better placed
358
00:15:55.160 --> 00:15:57.840
for us than for the north in M the evening.
359
00:15:57.840 --> 00:16:00.440
Brilliant. Venus is your beacon, low in the
360
00:16:00.440 --> 00:16:02.880
west after sunset. And for anyone with
361
00:16:02.880 --> 00:16:05.640
binoculars, Comet 10P Tempel
362
00:16:05.640 --> 00:16:08.560
2 is still tracking across southern skies.
363
00:16:09.010 --> 00:16:11.690
A soft little smudge that rewards a dark
364
00:16:11.690 --> 00:16:14.610
sky and a bit of patience. That's a
365
00:16:14.610 --> 00:16:17.290
southern hemisphere favoured comet, so make
366
00:16:17.290 --> 00:16:17.970
the most of it.
367
00:16:18.530 --> 00:16:20.690
Avery: So wherever you are on the planet there is
368
00:16:20.690 --> 00:16:23.010
something up there for you over the next 48
369
00:16:23.010 --> 00:16:25.570
hours. Northern skies get the once in a
370
00:16:25.570 --> 00:16:28.370
generation eclipse than the meteors. Southern
371
00:16:28.370 --> 00:16:31.170
skies get the planets Venus and the comet.
372
00:16:31.410 --> 00:16:33.970
Anna: If tomorrow sparks something for you, come
373
00:16:33.970 --> 00:16:36.570
and share it. TheNewAstronomyDaily
374
00:16:36.730 --> 00:16:39.570
IO has our full back catalogue, a
375
00:16:39.570 --> 00:16:41.610
news feed we keep fresh through the day,
376
00:16:41.850 --> 00:16:44.650
listener reviews and a contact form. So if
377
00:16:44.650 --> 00:16:47.170
you catch the eclipse or a great Perseid,
378
00:16:47.170 --> 00:16:48.610
tell us and sign
379
00:16:48.610 --> 00:16:50.090

Anna: socials astrodaily Pod that's
384
00:16:57.530 --> 00:16:59.970
Astronomy AstroDailyPod for Tuesday. Whatever
385
00:16:59.970 --> 00:17:02.590
your sky's doing M tomorrow. Glasses on for
386
00:17:02.590 --> 00:17:05.550
the sun, eyes up for the meteors from
387
00:17:05.550 --> 00:17:06.310
Anna and me.
388
00:17:06.310 --> 00:17:07.310
Avery: Thanks for listening.
389
00:17:07.550 --> 00:17:08.430
Anna: Clear skies.
390
00:17:22.650 --> 00:17:22.930
Mhm.
391
00:17:28.270 --> 00:17:28.910
Avery: We're told.
0
00:00:00.560 --> 00:00:02.800
Anna: Good day and welcome to Astronomy
1
00:00:02.800 --> 00:00:04.320
AstroDailyPod. I'm Anna.
2
00:00:04.400 --> 00:00:07.040
Avery: And I'm Avery. And if you only listen to us
3
00:00:07.040 --> 00:00:08.760
once this year, make it the next
4
00:00:08.760 --> 00:00:11.480
Anna: two days, because tomorrow, the 12th of
5
00:00:11.480 --> 00:00:14.080
August, the moon does something it hasn't
6
00:00:14.080 --> 00:00:16.000
done over mainland Europe since
7
00:00:16.079 --> 00:00:18.320
1999. It slides
8
00:00:18.400 --> 00:00:21.320
completely in front of the sun, the one and
9
00:00:21.320 --> 00:00:23.520
only total solar eclipse of
10
00:00:23.520 --> 00:00:24.560
2026.
11
00:00:24.960 --> 00:00:27.640
Avery: And then, once the sun goes down, the same
12
00:00:27.640 --> 00:00:29.520
new Moon that made that eclipse possible
13
00:00:29.760 --> 00:00:32.500
steps out of the way entirely. Hands us the
14
00:00:32.500 --> 00:00:35.060
darkest Perseid meteor peak in about 20
15
00:00:35.060 --> 00:00:35.420
years.
16
00:00:35.980 --> 00:00:38.540
Anna: One new moon, two headline events
17
00:00:38.620 --> 00:00:41.540
roughly 24 hours apart. We'll set the
18
00:00:41.540 --> 00:00:44.020
whole thing up for you. Northern and southern
19
00:00:44.020 --> 00:00:45.860
skies both, Plus a
20
00:00:45.860 --> 00:00:48.110
Avery: rough morning for one Chinese rocket, a, uh,
21
00:00:48.179 --> 00:00:50.140
quieter question mark hanging over another,
22
00:00:50.380 --> 00:00:52.820
and Japan quietly finishing off its own
23
00:00:52.820 --> 00:00:54.940
answer to gps. Let's get into it.
24
00:00:55.260 --> 00:00:57.980
Anna: So let's talk about tomorrow properly,
25
00:00:58.220 --> 00:01:00.970
because this is a genuinely rare one. Uh, a
26
00:01:00.970 --> 00:01:03.650
total solar eclipse happens somewhere on
27
00:01:03.650 --> 00:01:06.650
Earth roughly 18 months or so. But the
28
00:01:06.650 --> 00:01:09.530
last time totality touched down anywhere on
29
00:01:09.530 --> 00:01:12.410
the planet was April 2024 over
30
00:01:12.410 --> 00:01:15.130
North America. That's more than two years
31
00:01:15.130 --> 00:01:17.650
ago. Tomorrow ends that drought,
32
00:01:18.050 --> 00:01:20.610
and the geography of this one is strange and
33
00:01:20.610 --> 00:01:23.370
beautiful. Most total eclipses
34
00:01:23.370 --> 00:01:26.330
race roughly west to east across the middle
35
00:01:26.330 --> 00:01:29.330
of the globe. This one goes over the top of
36
00:01:29.330 --> 00:01:32.210
the world. The Moon's shadow first touches
37
00:01:32.210 --> 00:01:34.970
down in the far north of Siberia, then
38
00:01:35.050 --> 00:01:37.850
arcs up and over the North Pole, drops
39
00:01:37.850 --> 00:01:40.730
down onto eastern Greenland, crosses the west
40
00:01:40.730 --> 00:01:43.369
coast of Iceland, including Reykjavik,
41
00:01:43.530 --> 00:01:46.530
and finishes across northern Spain and just
42
00:01:46.530 --> 00:01:49.210
clips the northwestern corner of Portugal.
43
00:01:49.530 --> 00:01:52.330
Totality itself is brief. At most
44
00:01:52.330 --> 00:01:55.250
about 2 minutes and 18 seconds right on
45
00:01:55.250 --> 00:01:57.790
the centre line. Blink and you miss it by
46
00:01:57.790 --> 00:02:00.630
eclipse standards. But the setting more than
47
00:02:00.630 --> 00:02:03.430
makes up for it, because in Spain, the sun
48
00:02:03.430 --> 00:02:06.150
is hanging low in the west, close to the
49
00:02:06.150 --> 00:02:09.030
horizon. In the last light before sunset,
50
00:02:09.350 --> 00:02:12.309
imagine the sun's corona flaring out over
51
00:02:12.309 --> 00:02:15.190
a Spanish skyline at dusk. That's
52
00:02:15.190 --> 00:02:17.390
the image people have been planning trips
53
00:02:17.390 --> 00:02:20.310
around for years now before anyone
54
00:02:20.310 --> 00:02:22.430
in the Southern Hemisphere gets their hopes
55
00:02:22.430 --> 00:02:24.950
up. Let me be straight with you, because we
56
00:02:24.950 --> 00:02:27.670
always are on this show. This eclipse is a
57
00:02:27.670 --> 00:02:30.070
Northern Hemisphere event full stop.
58
00:02:30.390 --> 00:02:32.790
Totality is only over Greenland,
59
00:02:32.870 --> 00:02:35.630
Iceland, northern Spain and that little bit
60
00:02:35.630 --> 00:02:38.590
of Portugal. A much wider slice of the world
61
00:02:38.590 --> 00:02:40.830
gets a partial eclipse. Parts of North
62
00:02:40.830 --> 00:02:43.670
America, especially eastern Canada and
63
00:02:43.670 --> 00:02:46.190
the northeastern United States, will see the
64
00:02:46.190 --> 00:02:49.190
sun take a bite low in the sky near sunset.
65
00:02:49.350 --> 00:02:52.190
But here in Australia, we see nothing at
66
00:02:52.190 --> 00:02:54.950
all. So southern listeners, stay with us.
67
00:02:55.110 --> 00:02:57.550
Your night is coming later in the show, and
68
00:02:57.550 --> 00:02:58.470
it's a good one.
69
00:02:58.790 --> 00:03:01.670
Here's the scale that gets me though, add up
70
00:03:01.670 --> 00:03:04.470
everyone who falls under at least a partial
71
00:03:04.470 --> 00:03:07.270
shadow tomorrow across Europe, North Africa,
72
00:03:07.510 --> 00:03:10.230
northern Asia and much of North America.
73
00:03:10.310 --> 00:03:12.390
And you're talking on the order of, um, a
74
00:03:12.390 --> 00:03:15.110
billion people who can in principle
75
00:03:15.350 --> 00:03:18.310
look up and see the moon and sun overlap.
76
00:03:18.830 --> 00:03:21.710
One event, a billion potential witnesses.
77
00:03:21.950 --> 00:03:24.670
And it's not just a spectacle, it's a working
78
00:03:24.670 --> 00:03:27.350
day for scientists. Those couple of minutes
79
00:03:27.350 --> 00:03:30.070
of totality are one of the only times we can
80
00:03:30.070 --> 00:03:32.990
study the sun's corona, that faint outer
81
00:03:32.990 --> 00:03:35.230
atmosphere directly from the ground.
82
00:03:35.710 --> 00:03:38.310
Space agencies and observatories along the
83
00:03:38.310 --> 00:03:40.950
track are gearing up. The European Space
84
00:03:40.950 --> 00:03:43.470
Agency, for instance, is running a live
85
00:03:43.470 --> 00:03:46.030
broadcast from the Havalambra Observatory in
86
00:03:46.030 --> 00:03:48.820
Spain, stitching together telescope feeds and
87
00:03:48.820 --> 00:03:51.260
drone footage so that even if you're nowhere
88
00:03:51.260 --> 00:03:54.060
near the path, you can watch totality as it
89
00:03:54.060 --> 00:03:56.740
happens. The ever reality is the
90
00:03:56.740 --> 00:03:59.100
weather, of course. It always is with
91
00:03:59.100 --> 00:04:02.020
eclipses. Greenland is remote and cold,
92
00:04:02.100 --> 00:04:04.660
but the air coming off the ice sheet actually
93
00:04:04.660 --> 00:04:07.540
tends to clear the skies, so the odds there
94
00:04:07.540 --> 00:04:10.540
aren't bad. Iceland is Iceland. It
95
00:04:10.540 --> 00:04:12.900
could be crystal clear or socked in with
96
00:04:12.900 --> 00:04:15.320
cloud, sometimes within the same hour.
97
00:04:15.640 --> 00:04:18.320
And Spain has the best of both worlds for
98
00:04:18.320 --> 00:04:21.320
most travellers. Reliable late summer skies
99
00:04:21.480 --> 00:04:24.360
and the roads, airports and towns to actually
100
00:04:24.440 --> 00:04:27.440
get people into the path. That's why the bulk
101
00:04:27.440 --> 00:04:30.000
of eclipse chasers are converging on Spain
102
00:04:30.000 --> 00:04:32.960
and Iceland tonight, watching forecasts
103
00:04:32.960 --> 00:04:35.680
like hawks. We'll give you the exact viewing
104
00:04:35.680 --> 00:04:38.440
times for the path and for North America, um,
105
00:04:38.440 --> 00:04:41.170
in the sky watch at the end. For now, the
106
00:04:41.170 --> 00:04:44.010
headline is simply, After 27
107
00:04:44.010 --> 00:04:46.850
years, totality is coming home to Europe.
108
00:04:47.170 --> 00:04:49.250
And whatever the sky is doing where you are
109
00:04:49.250 --> 00:04:52.130
tomorrow. It is worth a look, it really
110
00:04:52.130 --> 00:04:52.450
is.
111
00:04:52.930 --> 00:04:55.410
Avery: And from something rising to something that
112
00:04:55.410 --> 00:04:56.530
came down the hard way.
113
00:04:57.010 --> 00:04:59.650
So yesterday was by any measure an
114
00:04:59.650 --> 00:05:02.530
extraordinary day for launches. Four flights
115
00:05:02.530 --> 00:05:05.490
across three countries inside about 12 hours.
116
00:05:06.210 --> 00:05:08.450
And China opened it with a hard one to watch
117
00:05:08.930 --> 00:05:11.810
along March 7 a. That's a state rocket
118
00:05:11.810 --> 00:05:14.130
from the big state contractor cask,
119
00:05:14.370 --> 00:05:16.690
lifted off from the Wenchang launch site on
120
00:05:16.690 --> 00:05:19.690
the island of Hainan. And about 85 seconds
121
00:05:19.690 --> 00:05:22.009
into the flight, still climbing, still on
122
00:05:22.009 --> 00:05:24.690
that first main burn, it exploded.
123
00:05:24.930 --> 00:05:27.890
A large fireball, a cloud of debris, and
124
00:05:27.890 --> 00:05:30.650
effectively a total loss of the vehicle and
125
00:05:30.650 --> 00:05:33.610
its payload. The payload was reported to be
126
00:05:33.610 --> 00:05:36.450
a communications satellite, Zhongsheng 4B,
127
00:05:36.770 --> 00:05:39.410
heading for a high orbit China. Space
128
00:05:39.490 --> 00:05:41.410
authorities hadn't put out a detailed
129
00:05:41.410 --> 00:05:43.610
statement as of our recording, so we're
130
00:05:43.610 --> 00:05:46.050
holding the payload detail lightly. But the
131
00:05:46.050 --> 00:05:48.930
outcome itself isn't in doubt. The rocket was
132
00:05:48.930 --> 00:05:51.930
lost. There's a bit of history here too. This
133
00:05:51.930 --> 00:05:54.770
was the 18th flight of the long March 7th A
134
00:05:55.010 --> 00:05:57.610
and awkwardly, the very first one back in
135
00:05:57.610 --> 00:05:59.890
2020 also ended in failure.
136
00:06:00.500 --> 00:06:02.660
So this is a rocket that's flown a lot and
137
00:06:02.660 --> 00:06:05.620
mostly, well, having a very public bad day.
138
00:06:06.180 --> 00:06:08.980
The bigger question is knock on effects. The
139
00:06:08.980 --> 00:06:11.580
long March 7 family is the workhorse that
140
00:06:11.580 --> 00:06:13.980
carries cargo up to China's Tiangong Space
141
00:06:13.980 --> 00:06:16.180
Station. So depending on what the
142
00:06:16.180 --> 00:06:19.060
investigation finds, some upcoming missions
143
00:06:19.060 --> 00:06:21.460
could slip while engineers work out what went
144
00:06:21.460 --> 00:06:24.420
wrong. Now, here's where I want to be careful
145
00:06:24.420 --> 00:06:26.920
because these storeys get tangled. That
146
00:06:26.920 --> 00:06:29.320
failure is one rocket. There was a second
147
00:06:29.560 --> 00:06:31.600
completely separate Chinese launch on the
148
00:06:31.600 --> 00:06:33.720
manifest for the same night, and it's a
149
00:06:33.720 --> 00:06:35.800
storey. We've been following the private
150
00:06:35.800 --> 00:06:38.280
company Landspace and its Zhu K3.
151
00:06:38.840 --> 00:06:41.000
Different company, different launch site.
152
00:06:41.000 --> 00:06:43.760
Jioquan, well over 2000 kilometres from
153
00:06:43.760 --> 00:06:46.280
Wenchang and a very different goal.
154
00:06:46.600 --> 00:06:49.560
Zhu K3 is a reusable stainless steel
155
00:06:49.560 --> 00:06:52.520
methane fueled rocket and last night's flight
156
00:06:52.520 --> 00:06:54.720
was its second attempt to fly to orbit and
157
00:06:54.720 --> 00:06:56.680
then bring its first stage back for a
158
00:06:56.680 --> 00:06:59.620
propulsive landing. Legs touchsc. The Falcon
159
00:06:59.620 --> 00:07:01.980
9 trick. And I want to keep our facts
160
00:07:01.980 --> 00:07:03.700
straight from last week. This would be
161
00:07:03.700 --> 00:07:05.820
China's fourth orbital class recovery
162
00:07:05.820 --> 00:07:08.780
attempt, not its first. China already landed
163
00:07:08.780 --> 00:07:11.180
an orbital booster back in July when a long
164
00:07:11.180 --> 00:07:13.980
3-10-B was caught in a net. What makes
165
00:07:13.980 --> 00:07:16.900
ZK3 different is the method, legs
166
00:07:16.900 --> 00:07:19.180
and engine thrust setting down on a pad
167
00:07:19.180 --> 00:07:21.340
rather than being caught. That's the
168
00:07:21.340 --> 00:07:24.180
milestone Landspace is chasing as we record.
169
00:07:24.420 --> 00:07:27.300
We don't have a confirmed result on that z k3
170
00:07:27.300 --> 00:07:30.140
attempt. And honestly, that's worth a word.
171
00:07:30.220 --> 00:07:33.020
Landspace has form for going quiet. Its
172
00:07:33.020 --> 00:07:35.420
debut flight last year was scrubbed and then
173
00:07:35.420 --> 00:07:38.100
postponed for days with barely a word before
174
00:07:38.100 --> 00:07:41.020
it eventually flew. So the silence tonight
175
00:07:41.020 --> 00:07:43.100
could mean the outcome just hasn't reached
176
00:07:43.100 --> 00:07:45.660
English language press yet. Or it could mean
177
00:07:45.660 --> 00:07:47.900
the flight quietly slipped. We're not going
178
00:07:47.900 --> 00:07:50.060
to guess. When it's confirmed, we'll bring it
179
00:07:50.060 --> 00:07:50.860
to you properly.
180
00:07:51.020 --> 00:07:53.860
Anna: A, uh, rocket lost and another we're still
181
00:07:53.860 --> 00:07:54.540
waiting on.
182
00:07:55.030 --> 00:07:57.630
Meanwhile, the sky above all of it is about
183
00:07:57.630 --> 00:08:00.550
to put on a free show. The Perseids.
184
00:08:01.030 --> 00:08:03.710
Now everyone knows the Perseids. They're the
185
00:08:03.710 --> 00:08:06.390
reliable old friend of the northern summer.
186
00:08:06.470 --> 00:08:09.230
The shower people actually plan barbecues
187
00:08:09.230 --> 00:08:11.310
and camping trips around. But
188
00:08:11.310 --> 00:08:14.150
2026 is special. And I want to
189
00:08:14.150 --> 00:08:16.790
explain why. Because it's a lovely bit of
190
00:08:16.790 --> 00:08:19.590
cosmic coincidence. The peak lands
191
00:08:19.590 --> 00:08:22.310
overnight on the 12th into the 13th,
192
00:08:22.780 --> 00:08:25.660
the same date as the eclipse. And that is
193
00:08:25.660 --> 00:08:28.220
not an accident. A, uh, total solar
194
00:08:28.220 --> 00:08:31.180
eclipse can only happen at New Moon when
195
00:08:31.180 --> 00:08:34.060
The Moon is between us and the Sun. And
196
00:08:34.060 --> 00:08:36.540
this year that new moon falls almost
197
00:08:36.700 --> 00:08:39.700
exactly on the Perseid peak. So
198
00:08:39.700 --> 00:08:42.380
the very thing that darkens the sun by day
199
00:08:42.700 --> 00:08:45.580
leaves the night sky completely moonless.
200
00:08:45.900 --> 00:08:48.540
No moonlight washing out the faint meteors.
201
00:08:49.040 --> 00:08:51.640
It's the best set of conditions the Perseids
202
00:08:51.640 --> 00:08:54.080
have had in roughly two decades.
203
00:08:54.480 --> 00:08:57.240
The meteors themselves are debris from a
204
00:08:57.240 --> 00:08:59.680
comet. Comet 109P,
205
00:08:59.840 --> 00:09:02.200
Swift Tuttle, a big one on a
206
00:09:02.200 --> 00:09:05.080
133 year orbit. Every
207
00:09:05.080 --> 00:09:07.600
August, the Earth ploughs through the trail
208
00:09:07.600 --> 00:09:10.480
of dust it's left behind. And those specks
209
00:09:10.480 --> 00:09:13.280
hit our atmosphere and burn up as shooting
210
00:09:13.280 --> 00:09:16.160
stars. When Swift Tuttle itself last
211
00:09:16.160 --> 00:09:18.520
swung through the inner solar system in the
212
00:09:18.520 --> 00:09:20.980
early 1990s, the Perseids
213
00:09:21.060 --> 00:09:23.980
briefly went berserk. Hundreds of meteors
214
00:09:23.980 --> 00:09:26.860
an hour. The comet's long gone back out
215
00:09:26.860 --> 00:09:29.780
now, so we won't see that this year, in
216
00:09:29.780 --> 00:09:32.580
fact, and I'll be honest, because a moon this
217
00:09:32.580 --> 00:09:35.140
sky can raise expectations. The
218
00:09:35.140 --> 00:09:37.660
forecasters are being measured about the raw
219
00:09:37.660 --> 00:09:40.660
numbers this year. The textbook figure is up
220
00:09:40.660 --> 00:09:43.140
to about a hundred meteors an hour under
221
00:09:43.140 --> 00:09:45.500
perfect conditions. But the meteor
222
00:09:45.500 --> 00:09:48.020
specialists are quietly expecting something
223
00:09:48.020 --> 00:09:50.420
more like 30 to 50 an hour from a
224
00:09:50.420 --> 00:09:52.640
genuinely dark site this time around.
225
00:09:53.280 --> 00:09:55.760
Activity dips a little this year before
226
00:09:55.840 --> 00:09:58.680
picking back up in 2027. There
227
00:09:58.680 --> 00:10:01.280
is one tantalising wildcard, though.
228
00:10:01.600 --> 00:10:04.520
Models suggest the Earth might just clip a
229
00:10:04.520 --> 00:10:07.120
couple of older, narrow dust trails around
230
00:10:07.120 --> 00:10:10.000
the peak one laid down almost a thousand
231
00:10:10.160 --> 00:10:13.160
years ago. If that happens, you could get a
232
00:10:13.160 --> 00:10:15.880
short burst of extra meteors. It's not
233
00:10:15.880 --> 00:10:18.400
guaranteed. The timing has hours of
234
00:10:18.400 --> 00:10:21.280
uncertainty and even the models don't promise
235
00:10:21.280 --> 00:10:24.060
a storm. But it's the kind of maydy that
236
00:10:24.060 --> 00:10:27.060
gets meteor watchers out of bed. The next
237
00:10:27.220 --> 00:10:29.580
genuine outburst that forecasters are
238
00:10:29.580 --> 00:10:32.500
confident about isn't until 2028,
239
00:10:32.660 --> 00:10:35.620
and that one will favour North America. So
240
00:10:35.620 --> 00:10:38.620
the storey of these Perseids isn't really a
241
00:10:38.620 --> 00:10:41.180
hundred an hour. It's the darkest
242
00:10:41.180 --> 00:10:44.060
skies in 20 years. A rare same
243
00:10:44.060 --> 00:10:46.860
day pairing with a total eclipse and a
244
00:10:46.860 --> 00:10:49.490
small chance of a bonus. We'll tell you
245
00:10:49.490 --> 00:10:52.330
exactly when and where to look at the end.
246
00:10:52.570 --> 00:10:55.370
Avery: Love it. And from ancient comet dust to some
247
00:10:55.370 --> 00:10:58.130
very modern hardware. Staying with that busy
248
00:10:58.130 --> 00:11:00.090
launch day, because not all of it was
249
00:11:00.090 --> 00:11:00.810
fireballs.
250
00:11:00.970 --> 00:11:03.970
Over In Japan, an H3 rocket lifted off
251
00:11:03.970 --> 00:11:06.410
from the Tanegashima Space Centre carrying a
252
00:11:06.410 --> 00:11:09.210
hefty navigation satellite. And with it,
253
00:11:09.210 --> 00:11:12.210
Japan took a quietly strategic step. The
254
00:11:12.210 --> 00:11:14.810
satellite is called Michibiki no. 7.
255
00:11:14.890 --> 00:11:17.570
Michibiki, meaning guiding or showing the
256
00:11:17.570 --> 00:11:20.090
way. And it brings Japan's quasi
257
00:11:20.090 --> 00:11:22.810
Zenith satellite system up to full strength.
258
00:11:23.130 --> 00:11:25.130
That's a bit of a mouthful. So here's the
259
00:11:25.130 --> 00:11:27.770
idea. Most of us rely on America's
260
00:11:27.770 --> 00:11:30.490
gps. It's brilliant. But in a place like
261
00:11:30.490 --> 00:11:33.090
Japan, narrow streets, high rise
262
00:11:33.090 --> 00:11:35.610
canyons, steep mountains, GPS
263
00:11:35.690 --> 00:11:38.330
signals can get blocked or bounce around and
264
00:11:38.330 --> 00:11:40.890
throw your position off. Japan's fix is
265
00:11:40.890 --> 00:11:43.810
clever. These quasi zenith satellites fly
266
00:11:43.810 --> 00:11:45.860
in looping orbits that, that keep at least
267
00:11:45.860 --> 00:11:48.860
one of them almost directly overhead, near
268
00:11:48.860 --> 00:11:51.780
the zenith over Japan and the wider Asia
269
00:11:51.780 --> 00:11:54.260
Pacific at all times. A signal coming
270
00:11:54.260 --> 00:11:56.860
straight down is much harder to block than
271
00:11:56.860 --> 00:11:59.700
one coming in low across a skyline. So
272
00:11:59.700 --> 00:12:02.700
Michibiki sharpens and reinforces GPS from
273
00:12:02.700 --> 00:12:05.100
directly above, getting positioning down to
274
00:12:05.100 --> 00:12:07.660
remarkable precision. With this launch,
275
00:12:07.660 --> 00:12:09.980
Japan has the satellites it needs to run that
276
00:12:09.980 --> 00:12:12.300
system as a full standalone service.
277
00:12:12.870 --> 00:12:15.550
And the strategic point is resilience. Japan
278
00:12:15.550 --> 00:12:18.030
now has its own regional backbone that keeps
279
00:12:18.030 --> 00:12:20.670
working even if it can't lean entirely on
280
00:12:20.670 --> 00:12:22.950
someone else's system. In a world where
281
00:12:22.950 --> 00:12:25.510
navigation underpins everything from farming
282
00:12:25.510 --> 00:12:28.070
to shipping to your phone maps, quietly
283
00:12:28.070 --> 00:12:30.950
owning your own overhead layer is a big deal.
284
00:12:31.590 --> 00:12:33.670
And there's a neat little footnote. This
285
00:12:33.670 --> 00:12:36.150
satellite is also carrying a hosted American
286
00:12:36.230 --> 00:12:38.990
payload, a space surveillance camera built
287
00:12:38.990 --> 00:12:41.470
for the US Space force. So, ah, a Japanese
288
00:12:41.470 --> 00:12:44.230
navigation satellite is quietly doubling as a
289
00:12:44.230 --> 00:12:47.070
US space watching sensor. Which tells you how
290
00:12:47.070 --> 00:12:49.310
closely the two allies now work together up
291
00:12:49.310 --> 00:12:52.110
there. Not a fireball, but arguably the most
292
00:12:52.110 --> 00:12:54.230
consequential thing that flew all day.
293
00:12:54.550 --> 00:12:57.390
Anna: From satellites that tell us exactly where we
294
00:12:57.390 --> 00:13:00.310
are to the oldest navigation tool there
295
00:13:00.310 --> 00:13:02.070
is the sky itself.
296
00:13:02.870 --> 00:13:05.510
Let's get you outside. This is the practical
297
00:13:05.510 --> 00:13:07.790
bit and we're doing both hemispheres as
298
00:13:07.790 --> 00:13:10.410
always. Northern friends, you've got the
299
00:13:10.410 --> 00:13:13.010
doubleheader. Southern friends, hang on. Your
300
00:13:13.010 --> 00:13:15.250
turn is coming and it's all yours.
301
00:13:15.890 --> 00:13:18.730
First, the eclipse, the timings. The
302
00:13:18.730 --> 00:13:21.050
moon's shadow sweeps through in the late
303
00:13:21.050 --> 00:13:24.010
afternoon and evening European time in
304
00:13:24.010 --> 00:13:26.930
rough universal time. Totality begins up
305
00:13:26.930 --> 00:13:29.754
in the high Arctic a little before 17
306
00:13:29.866 --> 00:13:32.690
UT, reaches greatest eclipse around
307
00:13:32.770 --> 00:13:35.690
1746 UT and finishes
308
00:13:35.690 --> 00:13:37.970
over Spain and Portugal by about
309
00:13:38.050 --> 00:13:40.890
1834 UT. On the ground,
310
00:13:41.130 --> 00:13:43.890
that means Iceland sees totality in the late
311
00:13:43.890 --> 00:13:46.490
afternoon. Spain sees it in the early
312
00:13:46.490 --> 00:13:48.890
evening with the sun low and close to
313
00:13:48.890 --> 00:13:51.370
setting. North America, you're getting a
314
00:13:51.370 --> 00:13:54.290
partial, not totality, and it's uh, a low
315
00:13:54.290 --> 00:13:56.890
in the sky, near sunset affair for
316
00:13:56.890 --> 00:13:59.770
eastern Canada and the northeastern United
317
00:13:59.850 --> 00:14:02.570
States. The further northeast you are,
318
00:14:02.730 --> 00:14:05.490
the more of a bite you'll see further
319
00:14:05.490 --> 00:14:08.400
west. And it fades out. And now the rule
320
00:14:08.400 --> 00:14:11.080
we never, ever trim. A, uh, partial
321
00:14:11.080 --> 00:14:13.960
eclipse is not safe to look at with the naked
322
00:14:13.960 --> 00:14:16.800
eye, not for a Second, you must
323
00:14:16.800 --> 00:14:19.760
use certified eclipse glasses or viewers
324
00:14:19.840 --> 00:14:21.440
that meet the ISO
325
00:14:21.440 --> 00:14:24.160
123122
326
00:14:24.320 --> 00:14:27.040
safety standard or watch by indirect
327
00:14:27.040 --> 00:14:29.440
projection like a simple pinhole.
328
00:14:29.760 --> 00:14:32.400
Ordinary sunglasses, smoked glass,
329
00:14:32.560 --> 00:14:35.200
phone cameras, none of that protects your
330
00:14:35.200 --> 00:14:38.150
eyes. The only moment it is ever safe
331
00:14:38.150 --> 00:14:41.110
to look directly is during total totality
332
00:14:41.110 --> 00:14:43.750
itself. And that only happens inside
333
00:14:43.830 --> 00:14:46.150
that narrow path in Greenland,
334
00:14:46.310 --> 00:14:49.190
Iceland and Spain. Everywhere else
335
00:14:49.190 --> 00:14:52.069
glass is on the whole time. Please
336
00:14:52.070 --> 00:14:54.790
look after your eyes then after
337
00:14:54.790 --> 00:14:57.310
dark. The Perseids for the Northern
338
00:14:57.310 --> 00:15:00.150
hemisphere the peak is overnight on the 12th
339
00:15:00.150 --> 00:15:02.950
into the 13th and with no moon at all,
340
00:15:03.190 --> 00:15:05.820
conditions are as good as they get. Best
341
00:15:05.820 --> 00:15:08.660
viewing is after midnight from roughly 2am
342
00:15:08.740 --> 00:15:11.540
until dawn when the shower's radiant climbs
343
00:15:11.540 --> 00:15:14.420
high. Get somewhere dark, lie back,
344
00:15:14.420 --> 00:15:17.060
give your eyes 20 minutes to adjust and
345
00:15:17.140 --> 00:15:19.940
don't stare at your phone. Realistically
346
00:15:20.020 --> 00:15:22.740
30 to 50 an hour from a dark sight.
347
00:15:22.900 --> 00:15:25.700
More if that dust trail wildcard comes off
348
00:15:26.180 --> 00:15:29.180
now. Southern hemisphere, this is yours. Two
349
00:15:29.180 --> 00:15:31.980
bits of bad news then the good stuff. You
350
00:15:31.980 --> 00:15:34.820
can't see tomorrow's eclipse and the Perseids
351
00:15:34.820 --> 00:15:37.600
barely clear the horizon for us because their
352
00:15:37.600 --> 00:15:40.480
radiant sits low in the north. So don't
353
00:15:40.480 --> 00:15:43.120
stay up chasing them from Sydney. Instead
354
00:15:43.440 --> 00:15:46.400
look before dawn. The pre dawn eastern
355
00:15:46.400 --> 00:15:49.320
sky right now has a lovely lineup of planets
356
00:15:49.320 --> 00:15:52.160
strung along it. A genuine naked eye treat.
357
00:15:52.400 --> 00:15:55.160
No equipment needed and much better placed
358
00:15:55.160 --> 00:15:57.840
for us than for the north in M the evening.
359
00:15:57.840 --> 00:16:00.440
Brilliant. Venus is your beacon, low in the
360
00:16:00.440 --> 00:16:02.880
west after sunset. And for anyone with
361
00:16:02.880 --> 00:16:05.640
binoculars, Comet 10P Tempel
362
00:16:05.640 --> 00:16:08.560
2 is still tracking across southern skies.
363
00:16:09.010 --> 00:16:11.690
A soft little smudge that rewards a dark
364
00:16:11.690 --> 00:16:14.610
sky and a bit of patience. That's a
365
00:16:14.610 --> 00:16:17.290
southern hemisphere favoured comet, so make
366
00:16:17.290 --> 00:16:17.970
the most of it.
367
00:16:18.530 --> 00:16:20.690
Avery: So wherever you are on the planet there is
368
00:16:20.690 --> 00:16:23.010
something up there for you over the next 48
369
00:16:23.010 --> 00:16:25.570
hours. Northern skies get the once in a
370
00:16:25.570 --> 00:16:28.370
generation eclipse than the meteors. Southern
371
00:16:28.370 --> 00:16:31.170
skies get the planets Venus and the comet.
372
00:16:31.410 --> 00:16:33.970
Anna: If tomorrow sparks something for you, come
373
00:16:33.970 --> 00:16:36.570

Anna and me.
388
00:17:06.310 --> 00:17:07.310

Mhm.
391

Avery: We're told.
