Deadline for comments on a million SpaceX "AI data centers" and a company that wants to deliver "sunlight as a service."

[the_turtle@mastodon.sdf.org]

@sundogplanets even more comments than Janet Jackson's tit?

[argv_minus_one@mastodon.sdf.org]

@sundogplanets

What is SpaceX even actually trying to do? Because putting AI data centers in space obviously isn't it.

Space is a vacuum. There's no heat-absorbing medium (air, water, etc) to use for cooling. Put a data center's worth of AI computers into a large space station, and the whole thing will burn itself to a crisp in short order.

Spacecraft use slow, simple computers for a reason. Several, actually, but one of them is that they don't use much power and don't make much heat.

@sundogplanets

Another of the aforementioned reasons is that there's a lot of bit-flipping cosmic rays out there. Your fancy NVIDIA AI chip isn't gonna work too well with no atmosphere protecting its delicate nanoscopic circuitry from all those high-energy particles.

Tl;dr: physics says no.

So either SpaceX somehow aren't aware of all this, or they've got something else in mind for all those space stations.

@argv_minus_one @sundogplanets they’re using the announcement to raise money/keep ahead of the joneses in the ai space

He’s already backtracked on mars…

@sundogplanets Sunlight as a̶ ̶s̶e̶r̶v̶i̶c̶e̶ environmental menace.

@sundogplanets another Elon scam to grab billionaires from our government. The US is so stupid

[smashedratonpress@mastodon.sdf.org]

@sundogplanets Thanks for providing templates and detailed instructions. Worked great, thanks. I filed comments on both of this insane proposals.

[lcruggeri@mastodon.uno]

@sundogplanets I envise a dystopian final, destroy the day while giving solar light only to those who pay. Night or day, just pay

The others will be at dusk or with no light 24h/24

[argv_minus_one@mastodon.sdf.org]

@glasspusher

Aw, c'mon, where's the villainy in that? You can't put a bunch of space stations into orbit without hiding giant lasers in them or something.

@sundogplanets @artfulrobot Science fiction is writing itself...

[w6kme@mastodon.radio]

@sundogplanets Just a reminder to all my Amateur Radio friends...

The bar for making comments has been set unfairly high, since it requires a CORES account. But we all have this account already, since it's a requirement for a ham radio license. So we are in a far better position than most of the public to comment.

It's up to us to comment for the millions of people denied the opportunity. Don't pass this chance up!

@lispi314@udongein.xyz pretty sure the heat from conversion losses on the satellite destroy that idea too. even a 15% loss is disastrous for that much power in a vacuum.

@sundogplanets You may consider signing the #A4E statement on Proposed Large Satellite Constellations: https://docs.google.com/forms/d/e/1FAIpQLSdnBbw-dATjyHVovhoDTtl_VYKWZTs7T8ZbF9sC7oRdDILrEw/viewform

I helped write and edit comments that were submitted by multiple organizations that I'm a member of about SpaceX's fucking stupid awful million sat filing, but I haven't submitted my own yet. After a week of emotionally grueling (but incredibly important) work supporting a good friend, battling the FCC submission process doesn't sound so bad anymore!

[gwozniak@discuss.systems]

@sundogplanets For what it's worth, I've submitted mine.

I don't have anything of substance to add except "this sucks", basically, but I'm sending the comment anyway.

[legit_spaghetti@mastodo.neoliber.al]

@sundogplanets Can we somehow rope your goats into leaving their comments as well? I get the sense they'd have much more reasonable and nuanced thoughts than the average SpaceX supporter.

[sundogplanets@mastodon.social]

Ok well another Starlink just reentered over Canada. So yeah. Definitely writing this now.

Time to live-toot an FCC submission while completely exhausted, but also watching a pleasant anime with friends and family!

[sundogplanets@mastodon.social]

Step 1: make a pdf. I think I'm going to mash together these two articles that I co-authored in the last couple weeks about very stupid things happening in orbit with huge consequences.

Too many satellites? Earth’s orbit is on track for a catastrophe – but we can stop it

Cultural, spiritual, and most environmental impacts aren’t taken into account when launching thousands of satellites.

The Conversation (theconversation.com)

A new space race could turn our atmosphere into a ‘crematorium for satellites’

Planned ‘megaconstellations’ of satellites could cause unforeseen harm to the ozone layer and climate systems. Global regulation is needed before it’s too late.

Unfortunately this'll require a bit of work because the different ways of doing citations. Or maybe I'll just leave the links in? I am pretty far beyond caring about formatting.

[randulo@mastodon.social]

@sundogplanets years ago, I read a SF story about the population permanently stressed because at night the saw the ICBM constantly moving like fireflies.

[sundogplanets@mastodon.social]

Ok that took a little longer than I thought. Do I want it to be on letterhead? Will my university be annoyed? I *am* writing as part of my job as a researcher who requires access to dark skies, but I am not writing on behalf of my university. Will go with blank background for this one.

Now working my way through the instructions here: https://aas.org/posts/advocacy/2026/02/how-submit-comments-satellite-applications-fcc

I already have a Cores account, signed in and clicking on things...
