Māori complain because Starlink satellites disturb their rituals and may make celestial navigation of canoes harder

February 10, 2025 • 9:30 am

Well, I’ll treat you to one more item about indigenous knowledge in New Zealand, this time when it clashes with modern science! It turns out that the Māori are beefing about there being too many satellites in the sky, and beefing for two reasons. First, this raises the possibility that the night sky might be changed, making it lighter, and that might make celestial navigation more difficult. Not that the Māori rely on that any more (actually, their Polynesian and SE Asian ancestors developed it), but their historical practice from hundreds of years ago might be made more difficult.

Second, the satellites are somehow said to interfere with a Māori ritual in which the steam from cooked food is allowed to float up toward the stars. (The ritual arose to give thanks for a good harvest.)  It is not clear to me how satellites would interfere with that, so you’ll have to ask the Māori.

Click below to read the excerpt from Stuff, a New Zealand news site:

Here’s the beefing about the ceremony (I’ve added translations):

A Māori scientist has warned our skies could become clogged with up to 100,000 satellites in the next five years – threatening thousands of years of Māori knowledge in the process.

The pollution could get so bad that stars seen by Māori ancestors would no longer be visible to the naked eye.

Elon Musk’s Starlink satellites have already interfered with a tuku wairua [food/steam] ceremony during Matariki, when whānau [members of a family group] who have died are released to the stars; while satellite proliferation threatens traditional waka hourua navigation [celestial navigation using double-hulled canoes].

Scientist, and Indigenous astronomy expert Te Kahuratai Moko-Painting is part of Sustainable Space – a group seeking to save Earth’s lower orbit, under 2000km, from uncontrolled development.

Moko-Painting often shows up in similar items, for he’s quite a vociferous activist.

Moko-Painting said about 15,000 satellites have been sent into space since the 1950s – about 7000 of those are still functional, and about 10,000 are still in space.

“Between 2022 when these estimates were made, and 2030, it’s estimated that we’ll have between 60,000 to 100,000 satellites in orbit.”

He said the about-3000 Starlink satellites in orbit were “already causing issues”.

. . . He got involved in the issue after the first Matariki public holiday in 2022, when he joined his wife’s whānau at Waahi Pā in Huntly for the hautapu (feeding the stars with an offering of kai [food].

“And just as we were doing our tuku wairua, just as we were sending on those who had passed on from that year, we had 21 Starlink satellites cutting through, right past the path of Matariki [the Pleiades star cluster.”

Apparently people thought that this was the stars’ response to the ceremony, and was propitious, but Moko-Painting—who admits that Starlink is important in communicating with rural communities—still has a beef:

“And those who knew would just say ‘no, that’s actually this man who loves the technology for launching satellites but makes them far too bright’ … and he does them in this line in an eye-catching kind of way, and that’s completely unregulated.”

I doubt that people will stop launching satellites because it somehow interferes with this ceremony. But wait! There’s more! As I said, there’s a possibility that too many satellites may interfere with celestial navigation, which only a few Māori still practice. But this is only a hypothesis, and hasn’t been shown, mainly because only a few stalwarts still use celestial navigation, and only as a way to keep alive that ancestral skill:

Even in the middle of the Pacific Ocean on a waka hourua, double-hulled waka used for voyaging, the night sky is 10% brighter than it used to be, Moko-Painting said. “So one could argue that 10% of what our tūpuna could see with their eyes while navigating is no longer visible to us.”

Master navigator Jack Thatcher has travelled tens of thousands of kilometres on waka hourua, as a guiding light that keeps his crews alive.

The Pacific covers a third of the planet. Thatcher’s journeys – using only stars, ocean swells and birds as guides – include a 3200km trip from Aotearoa to Rarotonga, which is only 67km wide.

. . . Having 100,000 satellites in orbit might be good for “pinpoint accuracy” all around the world, but those who rely on the stars for guidance won’t know which is a satellite and which isn’t.

“They’ll obliterate most of the patterns that we all depend on to help us find our way.”

He said the satellites were already being discussed in the voyaging community. Light pollution wasn’t the only problem – “eventually they’ll be rubbish”, Thatcher said.

“We’re entering that zone of global extinction, because we’ve polluted our planet, now we want to pollute our heavens.”

While the technology might be used instead to navigate the oceans, “that’s not the point”, he said.

“Indigenous knowledge is something that is a self-determination thing.”

It’s not clear to me, though, that if the night sky is 10% brighter than before, this would somehow efface or even impede celestial navigation. They give no evidence, but some want to kvetch about it anyway, because it apparently erases the achievements of the Māori’s ancestors (not the Māori themselves):

Māori know who they are because of their ancestors’ achievements. “And now you’re going to take that all away from us.”

The first waka [canoe] in this country used navigation knowledge that ancestors accrued over millennia, Thatcher said – travelling from Southeast Asia to Aotearoa almost 6000 years later.

Essentially, he said, if you can no longer navigate the oceans through the stars “it becomes book knowledge only”.

“Indigenous identity helps people to be who they are and enables them to be proud of who they are, because of their ancestral knowledge that they still hold on to.”

The whole idea of keeping indigenous knowledge alive was that “we’re not dependent on any technology”.

So Moko-Painting has joined a group of scientists calling for holding back on launching satellites.  The article ends abruptly:

SpaceX, which operates Starlink, did not reply to queries at time of publication.

The problem with all this is that these two problems haven’t been demonstrated. The navigation impediment is a theoretical possibility and won’t be known until people like Thatcher try it.  Since they can still do it successfully, even with all those satellites up there, I think this is not a serious concern. As for the satellites interfering with the smoke rising to the stars, that is pure superstition and doesn’t command concern from any rational person.

Livestream from Earth: video from the International Space Station

February 2, 2025 • 1:05 pm

Here’s a livestream video you may want to check in on from time to time. As Space.com describes, it’s from the ISS:

Cameras are officially rolling! Or, in this case, streaming.

SpaceTV-1, a set of Ultra High Definition 4k cameras from space streaming company Sen, was delivered to the International Space Station (ISS) last year, and is now broadcasting live views of Earth and space for all the world to see.

The London-based company is pursuing a mission to provide anyone and everyone with easy access to an experience usually reserved for astronauts — the overview effect. A phenomenon coined for the awe of seeing our planet from space and the effect it has on a person’s perception of humanity, Apollo 14‘s lunar module pilot NASA astronaut Ed Mitchell described the overview effect as, “an instant global consciousness,” accompanied with “an intense dissatisfaction with the state of the world and a compulsion to do something about it,” and Sen wants that for everybody.

. . . The SpaceTV-1 camera suite was delivered to the ISS in March, 2024, aboard a SpaceX Dragon spacecraft on the CRS-30 cargo mission last year. SpaceTV-1 was attached to the Bartolomeo platform on the European Space Agency’s (ESA) Columbus module. The package includes three cameras, providing three unique views of space around the ISS and Earth below.

A wide angle lens captures the long curve of Earth’s horizon, with the occasional piece of the space station moving in and out of frame. A tighter view focuses directly on Earth, showing a stretch about 150 miles x 110 miles (240 kilometers x 180 kilometers). The third camera looks at the space station’s forward docking port, connected the the Harmony module.

It’s very easy to get mesmerized by the video, but you can always keep it in the background of your computer screen (there are some replays as there is signal loss when the ISS is on the other side of Earth from the receiver, but there are also helpful descriptions at the bottom of the screen. It is a YouTube video.

Sunrise is very soon!

Today we have some photographs by Lou Jost of the recent Aurora Borealis that was visible from the U.S.  Lou’s notes are indented, and you can enlarge the photos by clicking on them.

Although Lou works in Ecuador as a biologist, he was visiting the U.S. and saw this as lagniappe:

The earth has just moved through one of the strongest solar storms of the last century, and on Oct 10 this produced one of the most spectacular displays of aurora borealis ever seen in the midwest US. There were  even reports of aurora borealis as far south as Mexico and Puerto Rico!

I was visiting my brother that night in southern Wisconsin near the Illinois border. He saw the NASA aurora forecast and we decided to head out to a dark spot to see what we could see. We had heard that mostly it would be invisible to the naked eye and we would need to use a telephone camera to see the colors. But even while we were driving the car to our dark spot, we began to see faint moving bands of light in the sky,

When we got to the dark spot we were astonished to see deep red lights mixed with pale teal green stripes. I thought the aurora was always just green but I now know that especially powerful solar storms make reds and purples and blues too. We saw all those colors, pulsing and re-grouping into stripes and swirls. I had never seen aurora borealis in my whole life, so I was deeply surprised by this display. It was captured by many observers around the country but I think what we saw in Wisconsin was as stunning and colorful as anywhere.

The attached photos are unedited straight-off-the-telephone handheld shots taken by Paul Jost and Ayesha Abbassi; the hooded head in one of the photos is me. The bright light on the lower left corner of one shot is the half-moon, blurred by camera movement.  I am sure this would have been visible from dark areas outside of Chicago, and maybe even from the Chicago lakeshore looking out at the darker skies above Lake Michigan. The aurora changes very quickly and it is necessary to watch the aurora forecast, which is based on actual solar activity measurements made from a space satellite, and it has a 35 minute lead time.

There are many good websites that discuss the complex causes of the aurora. I learned that the red we saw was very unusual and probably caused by oxygen excitation hundreds of kilometers above the earth, while greens are caused  by a different oxygen energy level emission lower in the atmosphere.

If you have good wildlife photos, don’t forget to send them in!  Thanks.

Today’s theme is astronomical phenomena, and we have two contributors. Both contributors’ words are indented, and you can enlarge the photos by clicking on them.

First, Bryan Lepore sends two photos and a video.

I submit two photos of the geomagnetic storm on Friday, 10 May, 2024 as viewed from latitude ~42 N ~71 W (Massachusetts), at about 10 PM.

Bryan adds this figure, which comes from a tweet by AuroraAlerts:

One more item occurred to me that should fit with the aurora photos : a map from Aurora Alerts on 10 May :

… you can see it goes down to New England. So I saw that indoors, and immediately stepped outside. Readers can scroll through Aurora Alerts to see the info, and I recommend subscribing.  I think there is supposed to be more solar activity than usual in the next so many months – some cyclic activity of many years length (I’d need a refresher).

Bryan also made a short video for YouTube showing the International Space Station flying by during the aurora:

Our second contributor is Rik Gern, who sent photos taken the day of the eclipse:

Here is a small batch that represents all the remaining pictures I currently have processed and ready to go. They are of varying quality, but there is a theme running thru them; they were all taken in my yard in Austin, TX on April 6th, the day of the full eclipse.

Where I live the totality lasted for about 90 seconds and I didn’t bother to try to photograph the eclipse itself because a lot of people who know a lot more about photography than I do were setting up to take and share some nice pictures of the corona and other great effects. Instead, because I was fascinated by the rapidly changing light, I took pictures of plant life around the yard as the early afternoon light got steadily darker and everything started to look like evening time, but without the long shadows. It was subtly disorienting.

The first picture is of one of my favorite volunteer plants, the false dayflower (Tinantia anomala).  I love the “face” in the flower! This species initially made an appearance in the yard about ten years ago and at first there weren’t many, but when I discovered what a good looking plant it is I let it grow pretty much wherever it made an appearance and now it dominates the back end by the compost pile.

This next plant, common hedge parsley, aka spreading hedge parsley or tall sock-destroyer (Trills arvensis), wasn’t fully in bloom at the time. Even when it does bloom the flowers are very tiny and easy to overlook. The leaves remind me of carrot tops, though I don’t know if they’re related.

The tufted yellow woodsorrell (Oxalis priceae) was growing at the base of a cactus plant. For the longest time I confused woodsorrel with clover and they do look similar, but their flowers are different and unlike clover, woodsorrel in not a nitrogen-fixing plant and livestock shouldn’t graze on it. Both are bee friendly though. You can learn more about the similarities and differences here.

It was too early in the year to observe flowers on this spineless prickly pear cactus (Opuntia ellisiana), but the new pads that appear every year are intriguing in their own right.This picture was taken just a few seconds before the eclipse reached totality.

Despite a light cloud cover at the time, the total eclipse was dramatic and picturesque, and I can understand why people travel a great distance to observe the phenomenon. The eclipse’s totality inspired the hours of photoshop processing that transformed the cactus picture into this personification of nature.

Today’s photos come from reader Bill Dickens, whose notes and IDs are indented. You can enlarge the photos by clicking on them, and don’t miss the eclipse photo at the bottom.

I’ve been camping at Flamingo, Florida in the Everglades National Park. April is a good time of year to visit with warm temperatures and before the rains arrive and turn much of the coastal prairie into mud. (The mosquitoes though are a constant.)

Here are some wildlife shots taken along the Coastal Prairie Trail – a 13-mile round-trip along a historical trail once used by local cottonpickers and fishermen. It’s now a part of the Everglades National Park. The trail winds through an open prairie of succulents and buttonwoods both leaved and dead, presumably from constant inundation by flooding.

It was the dragonflies that are the real star at this time of year. Swarms of them.

Plus a bonus shot taken of the eclipse. I drove from my home in Florida to the Texas Hill Country to view it from Tow, Texas. The weather was cloudy most of the morning leading up to the eclipse. Then the cirrus clouds were headed one way, lower-level clouds the other and five minutes before the eclipse it cleared and stayed clear.

The Wildflowers were out in the Hill Country and this makes it a pretty time of year to visit.

Coastal Prairie Trail:

Pileated Woodpeckers (Dryocopus pileatus) – there are actually two in the frame:

Osprey (Pandion haliaetus),:

Osprey with Fish tail:

Halloween Pennant Dragonfly (Celithemis eponina):

Blue Bonnets, the official flower of the Lone Star State, at Lake Buchanan in Tow, Texas  (there are 5 different species of Blue Bonnet. I’m not going to guess):

Loudest sounds ever

April 16, 2024 • 1:00 pm

Here’s a fun video with a range of sounds from an alligator to the loudest sound we know of, which you’ll have to watch to find out—and you’ll want to. (I have heard a white bellbird, and it was LOUD!)

There’s a wallet commercial from 3:00 to 4:00, so you can skip that minute.

I cannot vouch for any of the information given!

Reader Don McCrady sent some lovely photos of the eclipse (I thought readers would send ’em in en masse, but it didn’t happen). Don’t captions are indented, and you can enlarge the photos by clicking on them.

I thought you might like to show your readers some photos from this past Total Eclipse.

I flew down to a spot near Lampasas, Texas. Unfortunately, we had some issues with the clouds, but we did have sporadic clearing that allowed me to get some fairly good shots.

Here’s a shot from the partial phase as the moon encroaches the sun, here about to cover up the huge sunspot numbered 3628. This sunspot was easily visible to the naked eye through our eclipse glasses. (Even the Trumpanzees I was with were smart enough to wear them when looking at the eclipse.)

In this shot, the totality is just beginning and we can see Bailey’s Beads. These are the last vestiges of the sun as they become eclipsed behind the mountains and valleys of the moon’s surface, and are one of the most beautiful phenomenon to photograph during the eclipse.

Finally we have a shot near the end of totality showing the huge solar prominences, again visible to the naked eye.

These images were shot using a Canon EOS R5, a Canon RF100-500mm extended all the way to 500mm at f/8. Partial phases were shot through a mylar solar filter, and the totality was shot with no filter.

And from Susan Harrison:
