No. It's good to criticize this now, before everyone starts doing it. I really don't want ad banners in the sky twenty years from now.

I cannot wait for the day when everyone has equal access to launching their disco balls into space. I have one in my basement just taking up space, it should be taking up space .

That pun is out of this world!

My astronomer friend says this isn’t really different from any other satellite with reflective shielding.

But presumably those other satellites are at least serving a useful purpose.

I think it's an interesting project. That's enough for me to consider it useful, or at least not worthless.

I’d hardly call space a finite resource.

Access to space might be. https://en.wikipedia.org/wiki/Kessler_syndrome

Kessler syndrome is an issue, but not for this particular object. It will stay in orbit for about 9 months before decaying. Residual objects from a collision would decay even faster.

> The most commonly used orbits for both manned and unmanned space vehicles are low earth orbits, which cover an altitude range low enough for residual air drag to be sufficient to help keep the zone clear.

And I once did the math on how heavy a mylar spherical balloon would need to be to have the apparent size of the Moon from 150 km of altitude and concluded that it could be launched from an Ariane 5 (at about 14000 kg or so).

I'd be a very unpopular person if someone decided to pay for the project.

This is utterly, utterly overblown. The Space Station is thousands of times bigger and throws back a hundred times more light than this will. Every evening, for most of the populated world, dozens of brighter satellites than this go overhead. I just checked the orbits for my evening here - 57 brighter satellites. But what about the flashing? Well, we've got those already too. The old, awesome Iridium satellites have…

Those served an actual purpose though. They weren't just shoved into space just to say, "hey look at what we did". That's the point they're making. Don't pollute space just because you can. EDIT: typos

This also serves a purpose - there had to be a payload to properly test the rocket.

It'll come down in 9 months or so.

Also, from LEO, it's not that visible.

Graffiti artist here. Space junk is a general problem I understand so theres nothing special about this device other than that it doesn't serve as anything but a marketing gimmick/artistic gesture.

Street art / graffiti is done by people who want others to read their names and see their art. It's the ultimate act of hubris to say that others should experience your art unfiltered and without a choice in the matter. You invade public space, upset people's comfort zone, and get them to think. Even if it's just "wow look at all the colors and lines". Just wait till they start projecting ads on the moon then yall will be really pissed off.

Do you want space colonies, commercial stations and activity? Cause I don't think you'll get one without the other.

We can't have space colonies or commercial stations without space advertising?

No, but you can't until someone pays to develop the technology.

One could argue: this one gets press, which gets funding, which is quite important for science.

Great, NIMBYs now want to stop space development. And it's just for 9 months, take a chill pill. Personally I think it's awesome, I'm going to try to track it and show it to my daughter. I hope one day we'll have structures on the moon that are visible to the naked eye! Can you imagine how motivating and achievable that would make space exploration seem to a new generation.

Why don't you track the ISS instead. It is orders of magnitude more interesting than a disco ball.

Imagine explaining this to your daughter :

- Here is the ISS, people live there.

- This is the Hubble space telescope, it makes plenty of nice pictures.

- This is a communication satellite, it for making phone calls from anywhere in the world.

- This... is a giant disco ball, it is made so you can see it.

Putting up what is essentially a space billboard is the kind of space development we can do without. And this is what astronomers are complaining about. It is not for the object itself, it is for the precedent it sets.

Right... how does space advertising relate to that though? Are you saying that's the only viable business model for space travel and colonization?
