Japan's LED-stacked cubesat will burn Morse code into the heavens - definitely a "brave new world" in ways to increase light pollution. APers beware!

I think this Cubesat isn't going to bother us for long, objects like them tend to fall out of orbit quite rapidly at the altitudes where it is orbiting the Earth. It'll burn up completely when it does re-enter.

So there IS a good ending to the story.

Yes, a fiery end befitting a great many things that are undesirable to say the least. I doubt all those LED's will do is anything more than make this object easy to see with the unaided eye anyway.

You could always try to track it with green lazers.

I'm more concerned about what some marketing scumbag might do with this technology.

The Goodwill Blimp gone high tech????? That's what I'm afraid of. That, or they;ll start listening to that plan of a string of sattelites to help focus the suns energy to the dark side of the planet....

shoot them down for crying out loud ... I am almost serious ... for cryin' out loud, is there no escaping the stupidity of mankind ... now, even when you figure you'll pick up and move to some inaccessible place on earth, away from the city lights, they will light up the night skies from above ... and this from some Japanes "Professor"
%$&#@&% ... himiherrgotsakramentnochamoi ... I'm a Professor and PhD, but I think they should strip this idiot of all his accademic honors ...

I think a more likely and worrisome future is billboards or some other type of advertising in low earth orbit. The marketing folks seem to know no limits to placing ads everywhere there can.

"The marketing folks seem to know no limits to placing ads everywhere there can."

and the beancounter folks are finding ways to break everything down to a monetary value so they can come up with ways to charge you for stuff that used to be free/included in the cost....

I dunno, I think it's a pretty cool idea. Plus satellite passes only last 9 minutes. Plus, this sat would make a really sweet widefield shot if you caught it with a fisheye and had the Milky Way as a backdrop. I call dibs on this idea!

In the movie Bedazzled (with Peter Cook and Dudley Moore), the devil complains about his lapse in creativity: "There was a time when I used to get lots of ideas... I thought up the Seven Deadly Sins in one afternoon. The only thing I've come up with recently is advertising."

A CudeSat is 10x10x10cm in size.

There are already satellites that are way brighter than this tiny thing will ever be.

Personally, I'd just like to get a glimpse of it. But as others have stated, I hope it isn't a sign of bigger, more intrusive things to come...

I don't see the issue of lp. Some leads would doubtfully be any brighter than Venus.

All dashes in fixed intervals is not morse code. It's just a visual beacon. Still, I really don't like that they would do this as it really is nothing more than an annoyance for Astro Photographers and could indicate to people that perhaps space is best used for a digital bilboard of humongous size.
