Hi there, thank you for joining us yet
0:02
again on another episode of Space Nuts. My
0:04
name is Andrew Dunphy, your host, and good
0:07
to have your company. I've got
0:09
a couple of things to talk about on today's
0:11
show. Not all good
0:13
news, I'm afraid. One in relation
0:15
to Saturn's moon Titan. They've released
0:18
some new information about
0:20
the potential for life on
0:22
Titan, and that doesn't auger
0:24
well, unfortunately. They've been crunching
0:26
the numbers and looking at
0:29
the elephants, and they've basically
0:31
come up with an elephant in a room that
0:33
they don't like to look off. That
0:36
all makes sense, promise you that. And
0:39
we are also going to the United
0:41
Nations because there's been an agreement to
0:44
talk about something that needs to be talked about
0:46
so that they can talk about it again, and
0:48
then maybe make a decision about talking about whatever
0:50
they're going to talk about at the first meeting
0:52
that they're going to talk about. That'll
0:55
make sense as well. That's
0:58
all coming up on this episode of Space
1:01
Nuts. 15 seconds, guidance is internal. 10,
1:07
9, ignition sequence start. Space Nuts. 5, 4, 3,
1:09
2, 1. 1, 2, 3, 4, 5, 5, 4,
1:11
3, 2, 1. Space Nuts. Astronauts report it feels
1:14
good. And
1:18
joining me to unravel quite literally all
1:21
of that is Professor Fred Watson, astronomer
1:23
at large. Fred. Hello,
1:26
Andrew. How are you doing? I'm confused.
1:28
Well, join the club. Yes.
1:33
No, I'm all right. I'm all right.
1:35
Are you okay? Yeah, I'm much
1:38
better than I have been. Thank you. Now that
1:40
the antibiotics have got rid of the, it's
1:43
technically called rickettsia, but it's
1:45
usually also known as spotted
1:47
fever. That describes it perfectly.
1:49
And it was caused by a tick bite.
1:51
Yeah. So, yeah. It's
1:54
been a long haul, really, hasn't it? It
1:56
has, yeah. It's been about three weeks. I'm
1:58
seeing it. Nasty,
2:01
nasty. Let
2:03
us get stuck into the
2:05
news of this episode and
2:07
our first story concerns
2:10
Titan. Now Titan held a lot
2:12
of promise in terms of potential
2:15
life because we
2:17
know that it's got all those
2:20
elements for creating life plus probably
2:23
a subterranean ocean
2:27
or a sub ice ocean
2:29
that could mean that
2:32
the mix is right to create potentially
2:34
life and of course there's a big mission
2:37
going there in the not
2:39
too distant future and the
2:43
people who published this study were actually a
2:45
little bit worried that what they discovered might
2:47
put a torpedo in the mission but
2:50
it's probably going to do the opposite for
2:52
other reasons but let's sort of just get
2:55
down to Tintax. Titan
2:58
probably looked like one of
3:00
the best prospects for life
3:02
beyond Earth and now they're
3:04
starting to suggest that's probably
3:06
not true. What's happened? Yes,
3:09
so and I think this kind
3:13
of slightly depressing bit of this is that
3:16
it may well be that what has
3:19
been evaluated for Titan will apply to
3:21
the other ice moons like Europa and
3:23
Enceladus and now Mimas which we talked
3:25
about a couple of weeks ago. Yes.
3:28
All have sub ice oceans so
3:32
this is a study by
3:34
an astrologist Catherine Niesch and
3:37
what she's shown is
3:40
that the sub ice
3:42
ocean on Titan, so remember the model
3:45
of Titan it's a rocky world, it's
3:47
a big world, it's bigger than Mercury
3:50
which has an ocean overlaying the rock
3:53
and ice on the surface of that
3:55
and on the surface of the ice
3:57
there are other liquids which are liquid.
4:00
hydrocarbons. That's
4:02
another story which we might touch on in
4:05
a minute as well. But what Catherine has
4:08
done is looked
4:10
at how material
4:12
from the surface of Titan,
4:14
which is known to be
4:16
rich in hydrocarbons, how
4:19
that might filter down to
4:22
the subsurface ocean. And
4:25
basically the outcome is that
4:27
it is very very slow
4:29
indeed and you know not
4:31
something that might make for
4:34
a prebiotic
4:39
mix in the oceans of
4:41
Titan, the sub ice ocean. I'm
4:43
putting that succinctly. But basically the
4:45
story is this, excuse
4:48
me, and I
4:50
should say this study is published in the journal
4:52
Astrobiology. It's all about how
4:55
you know this transfer from the surface
4:58
which is going to be organic rich down to the
5:01
ocean. And so what
5:03
the mowling
5:06
looks at is the fact
5:08
that comets which
5:11
will have impacted Titan like they have
5:13
done the Earth and probably
5:15
more so in the early history of
5:17
Titan, comet hits
5:19
the surface, the
5:22
heat of impact melts the surface.
5:25
So you've got a pool of
5:27
liquid water for a little while
5:29
that's got the surface organics mixed
5:32
with it and what she has
5:34
done then is said
5:36
okay first of
5:38
all how many comets are going to
5:40
strike Titan every year and that
5:44
gives you an idea of the flow
5:46
of water rate carrying these organics from
5:48
the surface to the interior but
5:51
then to work out just
5:53
how they will get down
5:56
through the ice. I mean for there are all
5:58
kinds of unknowns in this I have to say. because
6:01
we don't actually know how thick that ice
6:03
layer is and we don't
6:05
know what the kind of consistency and what's underneath
6:08
it is. It may be a sort of slush
6:11
because we're talking about very low temperatures. But
6:13
that ocean is known to exist because
6:15
of this phenomenon of if you stand
6:17
on tight and your longitude changes and
6:19
that's because the surface is moving with
6:21
respect to the interior
6:23
core. Anyway, what
6:26
they discovered was that
6:29
every year, I think
6:33
it's every year, let
6:35
me just make sure I'm saying the right thing
6:37
here. Yeah, so this is
6:39
every year. Every year you
6:41
would get roughly seven
6:44
and a half tons of
6:46
glycine, which is the simplest of the
6:48
amino acids and is one of the
6:50
constituents of proteins in living organisms. And
6:55
I'll leave you to draw the line with the elephant
6:57
there, but the 7.5 tons of glycine are
7:00
going to filter down to the
7:02
ocean. Now, the ocean
7:06
is, we think, at
7:08
least 12 times the volume of the
7:11
Earth's ocean. So seven
7:13
and a half tons per year into
7:15
that isn't going to cut
7:18
the mustard when it comes to
7:20
forming life. Which is the equivalent
7:22
to the mass of an African
7:24
male elephant. That's where we're drawing
7:26
the analogy. Elephant in the
7:29
room. Yes, that's right. So one elephant's
7:31
worth of glycine per year going into
7:33
an ocean 12 times the volume of
7:35
Earth's oceans. You can see the difficulty
7:38
there. Yeah. Yeah. It's going to be
7:40
very, very dilute indeed. Now,
7:45
that's for a
7:48
world that is rich in
7:50
surface organic, surface chemicals containing
7:52
carbon. Whereas the other icy
7:54
worlds that were just mentioned,
7:56
Europa, Ganymede, Enceladus, They
7:59
Virtually.. No carbon compounds on
8:01
the surface. And so you know
8:03
if if Titans subsurface moon is
8:06
not going to be habitable because
8:08
of this very poor flow of
8:10
good stuff down from the surface,
8:12
that it's going to be worse
8:14
for the other. A You know,
8:17
the other ocean wells, the other
8:19
ice moons off the solar system.
8:22
So. I'd say
8:25
I have destiny set. Summarized it
8:27
very nicely. It's this work shows
8:29
that it is very hard to
8:32
transfer the carbon on Titan surface
8:34
to it subsurface ocean. Basically, it's
8:36
hard to have both the water
8:39
and the carbon needed for life
8:41
in the same place. And so
8:44
that's a as you said, there
8:46
is still much to learn about
8:48
about And Titans The Dragon fly
8:51
missions which will launch a double
8:53
quad. Copter Lander on
8:55
Titan. Twenty Twenty A is not that
8:57
far down the track. I've seen the
9:00
take a few years to get their
9:02
boats are not be exciting when it
9:04
happens to. was still excited about Tyson.
9:06
Ah but ah This kind of is
9:09
a bit of a downer when it
9:11
comes to the some some ocean a
9:13
sump sorry suffice ocean Well and of
9:16
the question for me is. How
9:18
do they know they most likely to
9:21
be right? Because they've had to make
9:23
assumptions, say on several levels in really
9:25
soon as Piper that had to assume
9:27
a certain number of comments, a certain
9:29
amount of the theory of Cat and
9:32
and how do we know that the
9:34
interior of the planet didn't already contain
9:36
all that. Ah,
9:39
exactly that.is a very
9:41
good questions and because
9:43
like all science your
9:46
working on assumptions and
9:48
you know you're you're
9:50
making these assumptions about
9:53
us Watts Ah what
9:55
this constitutes Arts witnesses
9:57
some says always been.
10:00
The best understanding that we have but
10:02
may not be the right answer. And
10:04
that's the beauty of science you know.
10:06
silly might turn up next week this
10:09
is or whether me that we've got
10:11
the com flown from. oh wait a
10:13
minute from we've done the math rock,
10:16
Santa and As.usually the masses been done
10:18
wrong. It's usually it's not one of
10:20
the assumptions might change because of new
10:23
discoveries us who are. So it's It's
10:25
like the old, this particular Astrobiology if
10:27
pulling together strands for many, many different
10:29
fields. Of science and and you're
10:31
making a conclusion on the basis
10:33
of them now you didn't have
10:36
a it. It may assume a
10:38
did mention liquid hydrocarbons some surface.
10:40
So it's a story not what
10:42
my know I know that exists
10:44
but die how Is it relevant
10:46
to this story? Well, my
10:48
take on this is less as a
10:50
mistake because I'm one of the things
10:52
that has excited astrobiologists in the past.
10:54
Certainly in the early days of the
10:57
Cassini Huygens Mission when we landed a
10:59
spacecraft on the surface of Tighten. The.
11:03
The. The fact that so so
11:05
the argument that sir niece and
11:08
her colleagues are making a a
11:10
very much on standard biology as
11:13
we know it's water based life
11:15
with Calvin as a So I
11:17
carbon based life with waters the
11:20
working fluid ah the and that's
11:22
certainly true of all lies that
11:25
we know we do have nothing
11:27
that works differently but that been
11:29
speculation that he could have a
11:32
different basis of lies. ah
11:34
and there was certainly ideas
11:36
put forward the bucket nearly
11:39
two thousand was which suggested
11:41
that maybe they were there
11:43
were organisms again carbon based
11:45
organisms but ones that use
11:48
liquid natural gas is they're
11:50
working fluid the a sane
11:52
and me saying which minds
11:54
breeze hydrogen and heat acetylene
11:56
which is another another carbon
11:59
containing come pound. And
12:01
there was a bit of a little bit
12:03
of a flush of excitement about
12:05
that when Cassini discovered
12:09
that both acetylene and
12:12
hydrogen are both depleted near the surface of
12:14
these hydrocarbon
12:18
lakes. Now, that observation might have gone
12:20
away. It's not something I've heard about
12:22
for a long time. But it does
12:24
mean that we shouldn't limit
12:26
ourselves to looking at life as we
12:29
know it, Jim, because that's
12:31
carbon-based life on a water working fluid.
12:33
There might be
12:39
other possibilities. And Titan might be a
12:41
place where there exists... Yeah, OK. So
12:44
we can't absolutely write it off. But
12:46
the evidence based on certain mathematical
12:49
assumptions does
12:52
sort of tip a bit of
12:54
water on the Titan
12:57
theory. Cold water,
12:59
too. Definitely cold water. I think I've
13:01
got a solution, though. Let's go to
13:03
Titan and build a room. I reckon
13:06
if we go inside that
13:09
room, we will find an elephant. On
13:13
its way down through the ice. Maybe. It's
13:17
got to be a bit of
13:19
a disappointment for people, even though
13:22
they're saying, oh, no, no, this
13:24
new horizon, the Dragonfly, sorry, mission,
13:27
we'll go ahead. We're still excited. There's so many
13:29
more questions to answer. Well, that's right. But it's
13:31
got to be a bit of a gut punch
13:33
to hear this. Yeah,
13:37
yes. It's science. Yeah,
13:39
it's science. We roll with the
13:41
falls. But,
13:47
you know, and once again, Titan is
13:49
of vast interest, not just because of
13:52
the possibility of there being life there. It's
13:54
a huge interest. It's unique.
13:56
It's the only world in the entire universe
13:58
that we know. other than the
14:01
Earth where there are liquid pools of
14:03
liquid and its hydrocarbons are on water,
14:06
which are in equilibrium with the atmosphere. So you've
14:08
got this weather cycle there, you get
14:11
carbon methane and ethane rain.
14:14
There will be, Andrew, get
14:17
this, there will be methane and
14:19
ethane rainbows on Titan, which will
14:21
have a different radius from rainbows
14:23
on Earth because it's water that causes our
14:26
water droplets that cause our rainbows, it'll
14:29
be water, sorry, methane, ethane droplets that
14:31
cause theirs and they've got different refractive indices.
14:33
Stuff like that is going to be fabulous
14:35
for dragonfly. Yeah. Well, how long is that
14:37
going to take to get there though? Yeah,
14:40
that's the problem a long time. Yeah. So
14:43
even though the launch is what, 2028,
14:46
by the time it gets there
14:49
and gets down to business, it'll be much,
14:52
much later. Yeah. I'm not
14:54
sure what the orbital trajectory is. There'll be
14:56
slingshots involved, I'm sure, but I don't know
14:58
what the details are. Anyway,
15:02
yeah, something still to look forward to and
15:05
it's not, you know, it's an
15:07
interesting comment. I see
15:09
it as a comment on
15:12
our journey towards seeking
15:14
life elsewhere in the universe. Indeed.
15:17
Right. If you'd like to read
15:19
that story in full, you can
15:21
find it on the SciTechDaily website.
15:23
This is Space Nuts Andrew Duncly
15:25
here with Professor Fred Watson. Let's
15:29
take a short break from the show
15:32
to tell you about our sponsor NordVPN.
15:34
Now I've talked to you very, very
15:36
regularly about virtual private networks and the
15:38
benefits that you gained, particularly if you're
15:40
using wifi devices
15:43
in a public place to protect
15:45
you from scammers or hackers
15:47
or, you know, just generally protect
15:49
you in an
15:52
overall sense. But another
15:54
thing that I've claimed in the past is
15:57
the speed at which NordVPN
16:00
can operate even when you're
16:02
using a server in another country. So I'm going to
16:04
prove it. Right now I'm going to
16:06
do a speed test on my
16:09
own internet service. I have not got
16:11
NordVPN connected right at this moment so
16:14
I'll pick the server. Let me
16:16
just change it to the one
16:18
I use regularly. Okay so I'm
16:20
going from my server to another
16:22
server, no VPN, speed test
16:25
and we'll do a check
16:27
on how fast my internet
16:29
service is. Okay so there
16:31
it's pushing up just over
16:34
a hundred megabits per second
16:36
download as it is. Alright
16:38
just peaked at 106 actually so I'm
16:41
getting more than I'm paying for through
16:43
my standard service and the
16:46
upload speed is around 40.
16:48
Okay let's
16:50
stop that and now we
16:53
got to do it via NordVPN.
16:55
So I'll open my server and
16:59
I will click the quick connect so
17:01
it'll pick its own server
17:03
to connect through while I'm doing this
17:07
and it only takes a few seconds
17:09
and then we okay we are connected
17:11
so we've connected to Australian
17:13
server number 653. I'll
17:16
have to close the browser and open
17:18
it again so that it gets a
17:20
fresh connection via the VPN and
17:22
then we will do a speed test.
17:25
Alright speed test and
17:28
I'll use exactly the same server so that
17:30
we can compare the numbers. Can
17:32
you remember what I said before? Find
17:36
the optimal server. Alright I'm going to change it to,
17:38
where did it go? There it is that one. So
17:41
once again of course the
17:43
server that I'm going through now is different
17:45
from my regular server because I'm using a
17:48
VPN. So click go let's see
17:50
what the numbers say and
17:53
boom 99 100 yeah so what
18:00
have I lost? There, 102. I've
18:04
lost practically nothing, 103. So around the
18:06
102, 103 megabits per second
18:09
download. So I'm still getting more
18:11
than I'm paying for and the upload is continuing
18:14
to hang around the 36, 37
18:17
megabits per second. That's with the
18:19
VPN connected. So
18:21
that's NordVPN. It offers high
18:24
speed access
18:26
to their service. You don't lose
18:28
anything in the translation, maybe one
18:30
or two megabits per second. Sometimes
18:32
it's even faster than your regular
18:34
connection. It is a great service.
18:37
It's well worth getting, not only for your peace
18:39
of mind, but also for your continuity of service.
18:42
And I stand by it. I've been using
18:44
it for a very long time, very happy
18:46
with it and all those other services that
18:48
go with it that I find really valuable.
18:50
So where do you get it? All right,
18:53
nordvpn.com/space nuts.
18:56
That's nordvpn.com/space
18:59

19:23
back to the show. The
19:28
second half of our program,
19:30
Fred, is dedicated to bureaucracy.
19:34
Not entirely. I'm probably being a bit too tough,
19:36
but it's finally come to pass that the United
19:38
Nations has
19:41
put on an agenda for a meeting later this year
19:43
that they will be looking into the issue of
19:47
concentrations of satellites or satellite constellations or
19:49
whatever you want to call them. Because
19:53
as we speak, there are over a hundred satellites in
19:55
the world. eight
20:00
thousand satellites in orbit around Earth and
20:02
there are plans to send up many,
20:04
many, many more. Even Rwanda wants to
20:07
get in on this. They announced
20:09
a few years ago now that they would put
20:11
300,000 satellites in orbit. SpaceX wants to put 60,000
20:14
up there and there are so many others
20:20
that want to add to that number
20:23
and it's starting, well it's beyond becoming
20:25
a concern for those who
20:27
use telescope,
20:29
visual telescopes and radio telescopes
20:31
because you want to
20:34
keep the skies dark and quiet and having
20:36
hundreds of thousands of satellites orbiting
20:39
the planet or instant geostationary orbit
20:41
probably would make that difficult. It's
20:45
a challenge. So this story goes
20:47
back really to 2029. Sorry,
20:49
doesn't go back to 2029. See
20:53
I'm still not quite well enough. I felt
20:56
very old there for a moment. Yes, past
20:58
that. It goes back to 2019, in fact May 2019, when
21:03
the first tranche of Starlink
21:05
satellites were launched and astronomers were
21:07
taken by surprise and when
21:09
they realized that SpaceX
21:11
had approval for another 12,000 of them,
21:13
they started to get upset.
21:18
So that's the backstory. Now this is
21:20
a story that I've been very closely
21:22
involved with Andrew because he's part of
21:24
my job to help
21:26
to counter this issue and since that
21:28
time there's been
21:32
a lot has happened,
21:34
astronomers grumbled like man to start
21:37
with but they have since
21:39
then had many many conferences, done
21:41
a lot of work on actually
21:44
evaluating the risk to astronomical observation and
21:47
you're quite right it's both optical
21:50
telescopes and radio telescopes which
21:52
were affected by this. So
21:57
all of that has led A
22:00
couple of years ago to the formation by
22:03
the International Astronomical Union, which is the sort
22:05
of governing body of astronomy, something
22:08
that is called the Centre for the
22:11
Protection of the Dark and Quiet Sky
22:13
from the Effect of Satellite Constellations, usually
22:16
abbreviated to the CPS. It's
22:18
a lot easier to say.
22:20
Yes, of course. In
22:22
fact, it's a lot of colleagues and
22:24
friends of mine who are involved with that. So
22:27
that's one
22:30
level. And that organisation, the
22:32
CPS, one of its, it
22:34
does many things. It works out
22:37
how you can remediate observations that have
22:39
been affected by satellite transmissions, whether
22:41
they're radio or satellite reflections in
22:44
the case of optical
22:46
telescopes. They've done a
22:48
huge amount of work on that. There is
22:50
also a strong
22:52
part of the organisation which
22:54
is about the aging with
22:56
the space industry, which in
23:00
the bottom line is one of the most
23:02
important ones because the space industry is
23:04
the key to this. And in
23:07
particular, the biggest, basically
23:10
the person or the organisation with
23:12
the most investment
23:15
in this so far is SpaceX
23:17
with Starlink. And
23:20
I'm very glad to say that
23:22
SpaceX has been one of the
23:24
foremost, if not the foremost company
23:26
to engage with astronomers and look
23:28
at the problems and how you
23:30
fix them. And indeed,
23:33
there are some really good people
23:35
working within the Starlink organisation who
23:37
are actually also members of the CPS,
23:40
the IAU Centre. So there's a
23:42
lot of, there's a good news
23:44
aspect to this story. The less
23:47
good news aspect was something
23:50
I was closely involved with this time
23:52
last year. I just,
23:54
in fact, I was just returning from
23:58
a couple of weeks in Vienna. where
24:01
the Science and
24:03
Technical Subcommittee of
24:06
the United Nations Committee
24:08
on the Peaceful Uses of Outer Space
24:10
had just finished its annual two week
24:12
meeting. And during that meeting
24:14
we were very kind
24:18
of urgently trying to get this
24:20
issue of the
24:22
deleterious effects of satellite constellations
24:24
on astronomy onto
24:26
the agenda, the permanent agenda of COPWOS,
24:29
the Committee on the Peaceful Uses of
24:31
Outer Space. That
24:33
proved difficult because everything
24:38
in the UN works by consensus,
24:40
it's not a vote, everybody has
24:42
to agree and there were certain
24:44
nations which would not agree to
24:47
this agenda item. Was
24:51
the United States one of them? The
24:54
United States was not one of them, no,
24:56
it was other countries who
24:59
were constantly in the news because
25:02
of wars and things of that sort. So
25:05
it was all about, you
25:08
know, it was all about trying
25:11
to push this through. We were very disappointed at
25:13
the end of that couple of weeks that
25:16
we didn't make it through with the agenda
25:18
item. There was a full meeting of the
25:20
Committee on the Peaceful Uses of Outer Space
25:22
rather than their Scientific and Technical Subcommittee which
25:25
is what I was involved
25:27
with. That full committee met
25:29
in June and the hope was that they
25:31
would push it forward there too. That
25:34
didn't happen either because of another
25:36
country that objected and
25:39
in fact that's where it stood. And you might
25:41
remember that in October I was at a meeting
25:43
in La Palma in the Canary Islands which was
25:46
actually an International Astronomical Union meeting where we
25:48
discussed this again and there were glimmers of
25:51
hope there that we could see a way
25:53
forward to take
25:56
This issue onto the agenda
25:58
of the UN. And
26:00
okay so in the meeting this
26:02
just gone which I wasn't arts
26:04
and in fact it was in
26:07
personally meeting so it couldn't even
26:09
that login online. But my colleagues
26:11
from the Smiles Twenty Space Agency
26:13
with that's fantastic people who are
26:15
right across this issue and in
26:17
the end it was agreed. So
26:19
the results A very nice International
26:22
Astronomical Union press release which is
26:24
headed as you said, United Nations
26:26
agreed to address the impact of
26:28
satellite constellations on astronomy. And
26:30
so the agenda items
26:33
which will. Come up
26:35
now for the next five years
26:37
and that is pretty amazing for
26:39
you and issues. Has the title
26:41
dark and Quiet Skies Astronomy and
26:43
large Constellations addressing emerging issues and
26:45
challenges and I hope that I
26:47
might be involved with that were
26:49
down the track and will show
26:52
with us going to happen, but
26:54
it certainly very close to my
26:56
heart to be able to do
26:58
that so that's a step forward
27:00
Now as you have kind of
27:02
indicated at the start of this.
27:04
Segment. Of
27:06
the wheels of the You
27:09
and turned very slowly indeed.
27:11
And this is an issue
27:13
on which essentially nimbleness is
27:15
really the watchword began. You
27:17
know, the industry's moving ahead
27:19
so quickly. But
27:21
I do believe that what the
27:23
the you and agreement now will
27:26
do is it just adds that
27:28
little bit more gravitas to what
27:30
we're already doing a in the
27:32
and based on the world. Engaging
27:35
with a space industry, it's looking
27:37
at how how things can be
27:39
improved and how we can. health.
27:43
Effects of these Mexicans license Because
27:45
the bottom line is the make
27:47
constellations are actually doing good things.
27:49
You know there are providing internet
27:51
services where they would never been there
27:53
before and with centers on posts
27:55
with the wars that are going
27:57
on at the moment. How those
27:59
services. The invaluable am.
28:02
Very. The industry itself i
28:04
should just start is a postscript
28:06
to this is concerned about the
28:09
crowding a space because you know
28:11
this Kessler syndrome homes to all
28:13
one big car collision and you've
28:16
suddenly gotten so much down in
28:18
space becomes unusable Exactly Yeah, I'm
28:20
I have a Devil's Advocate question
28:23
a cabbie you and now agreed
28:25
to put this on the agenda
28:27
and discuss it and. Look
28:30
at the problem. Over
28:32
the next five years how much power as
28:34
they got to actually deal with it when
28:36
the time comes while the time has come.
28:38
But how much power like up. So.
28:42
That they do have power in the sense
28:44
that. It
28:47
may well be that another
28:49
body that sort of sits
28:51
under the you end up
28:53
which is International Telecommunications Union
28:55
and thus somebody that actually
28:57
allocates frequencies and basically says
29:00
yes, he can launch his
29:02
spacecraft and that is. There
29:05
is sinking which I think is shared
29:07
across the board that that. You
29:10
know them, their mandate needs to be
29:13
tightened up that the I to you
29:15
need some revisions in the way deals
29:17
with the with requests for or be
29:19
moon is an orbital slots. And
29:22
and that can be done that?
29:24
That's something that will probably be
29:27
encouraged by. It's the fact that
29:29
the says this an agenda item
29:31
is gonna head means nothing. If
29:34
I may just segue from the
29:36
andrew to another story, that kind
29:38
of. Highlights of really
29:40
what we took him out.
29:42
and that is the announcement
29:44
again from Spacex that they
29:47
are going to D orbits
29:49
a hundred of it's older
29:51
Starlink satellites in order to
29:53
so the clear the air
29:55
a bit it it's tubes
29:57
to to basically it's. Get
30:01
rid of over a threat for
30:03
collisions because I think these are
30:05
the older. I think this is
30:07
among the first group of the
30:09
stalling satellite they want to call
30:11
Diversion One satellite. Yes, And so
30:13
for the next few weeks ago,
30:16
the Duvet hundred of them. Now,
30:18
exactly as you said, Starlink already
30:20
has more than five thousand diseases
30:22
in orbit, but that the later
30:24
versions are actually I think more
30:26
sophisticated in their collision avoidance capabilities
30:28
and things of that. Sort of
30:31
so that you know a Spacex
30:33
announced in a in a in
30:35
the next a tweet mix Mcclain
30:37
metaphors that's A that did This
30:39
is the right thing to do
30:41
to keep sets by safe unsustainable,
30:43
which is really what it's all
30:45
about and or have say and
30:47
of said this already. But as
30:49
your Spacex as they're stalling, translations
30:51
are certainly the biggest offenders in
30:53
terms of numbers, but they are
30:55
also the ones that have come
30:58
closest to the party by. It's
31:00
things. Like the visor Sat switch
31:02
were aiming to stuck in the
31:04
satellites we now have reflective coating.
31:06
Some the satellites that can deflect
31:08
beats the being so served from.
31:11
Of light from the some rather than
31:13
those being spanked scattered down to earth
31:15
where the become visible in twilight that
31:17
you been them straight out into space
31:19
where and make the satellites invisible it
31:21
reduces and brightness and are also. Engaging
31:24
in some quite stringent mitigation properties in
31:27
regard to radio astronomy as well as
31:29
so in that regard. This that you
31:31
know is it is a good news
31:33
story is it's is. it is one
31:36
that still a difficulty seems to me
31:38
will never be the same again with
31:40
all this satellite. Constellation Interference were learning
31:42
how to deal with it and and
31:44
and I think forging very good relationships
31:47
with the Space industry. How the space
31:49
industries listening to this got a subset
31:51
to be a winner and spent on
31:53
let's hope the You In works faster
31:55
than than Arrows in traffic authorities here
31:57
in New South Wales who have just
31:59
agree that we should register horse drawn
32:01
vehicles. A
32:04
T S good. How about open
32:06
sell some spots Mans? A Yeah
32:08
it is interesting news and you
32:10
can not find it more at
32:13
the International Astronomical union.org website out
32:15
