Rules (2024-08-30)

  1. This is an English-language community. Comments should be in English. Posts can link to non-English news sources when providing a full-text translation in the post description. Automated translations are fine, as long as they don't overly distort the content.
  2. No links to misinformation or commercial advertising. When you post outdated/historic articles, add the year of publication to the post title. Infographics must include a source and a year of creation; if possible, also provide a link to the source.
  3. Be kind to each other, and argue in good faith. Don't post direct insults nor disrespectful and condescending comments. Don't troll nor incite hatred. Don't look for novel argumentation strategies at Wikipedia's List of fallacies.
  4. No bigotry, sexism, racism, antisemitism, islamophobia, dehumanization of minorities, or glorification of National Socialism. We follow German law; don't question the statehood of Israel.
  5. Be the signal, not the noise: Strive to post insightful comments. Add "/s" when you're being sarcastic (and don't use it to break rule no. 3).
  6. If you link to paywalled information, please provide also a link to a freely available archived version. Alternatively, try to find a different source.
  7. Light-hearted content, memes, and posts about your European everyday belong in other communities.
  8. Don't evade bans. If we notice ban evasion, that will result in a permanent ban for all the accounts we can associate with you.
  9. No posts linking to speculative reporting about ongoing events with unclear backgrounds. Please wait at least 12 hours. (E.g., do not post breathless reporting on an ongoing terror attack.)
  10. Always provide context with posts: Don't post uncontextualized images or videos, and don't start discussions without giving some context first.

(This list may get expanded as necessary.)

Posts that link to the following sources will be removed

Unless they're the only sources, please also avoid The Sun, Daily Mail, any "thinktank" type organization, and non-Lemmy social media (incl. Substack). Don't link to Twitter directly, instead use xcancel.com. For Reddit, use old:reddit:com

(Lists may get expanded as necessary.)

Ban lengths, etc.

We will use some leeway to decide whether to remove a comment.

If need be, there are also bans: 3 days for lighter offenses, 7 or 14 days for bigger offenses, and permanent bans for people who don't show any willingness to participate productively. If we think the ban reason is obvious, we may not specifically write to you.

But Luch-1 may no longer be functional. On January 30, Earth telescopes observed what appeared to be a plume of gas coming from the satellite. Shortly after, it appeared to at least partially fragment.

“It looks like it began with something to do with the propulsion,” said Marchand, adding that afterwards there “was certainly a fragmentation” and the satellite was “still tumbling”.

Smells like a shadow space war.

Relevant 39c3 talk (but dealing with civilian sattelites): Don't look up

[–] floofloof@lemmy.ca 63 points 21 hours ago (2 children)

The official expressed concern that sensitive information — notably command data for European satellites — is unencrypted, because many were launched years ago without advanced onboard computers or encryption capabilities.

Maybe those should be replaced?

Uuh yeah i do (because taxes), but its being funneled into the pockets of corrupt politicians, the car industry and AI slop.

[–] pmirallesr@piefed.social 3 points 16 hours ago

Hah. I don't disagree that money is not well used, but trust me, replacing those satellites is no small endeavour on many levels: Industrial capacity, launch capacity, workforce capacity, cost, will...

According to the article the satellites that were shadowed were:

Satellite Launch date
RASCOM-QAF1R August 4, 2010
Eutelsat 3B July 2014
Eutelsat Konnect VHTS September 7, 2022
Astra 4A November 18, 2007
SES-5 July 9, 2012
Eutelsat KA-SAT 9A December 26, 2010
Eutelsat 9B January 30, 2016
Eutelsat 3C February 12, 2009

That wasn't that long ago relative to encryption being done on computers.

I'm a software engineer in space and the things I've heard are astounding. Basically space software as a sector is super backwards and operated under a "We're too far away to be hacked" mentality for way too long. Thankfully, that is changing, and the EU Space Act mandates cybersec in some cases

[–] CanadaPlus@lemmy.sdf.org 1 points 9 hours ago

How quickly could a radio wave get to space? Three minutes? Nah, it's fine. /s

What's it like typing in zero-G? Does the keyboard float away from you?

[–] pmirallesr@piefed.social 3 points 16 hours ago

No, we tape it to the table, duh. But it's annoying when the tape covers the spacebar!

[–] raspberriesareyummy@lemmy.world 2 points 17 hours ago (3 children)

What I observe is not so much a "we're too far away to be hacked" mentality, but rather a lackluster approach to software: "Software is just the cream on top that enables the real power of the hardware. So let's have our hardware engineers do the software as a side exercise. Surely it can't be that hard." Then you get hardware engineers, most of whom are fucking stupid in terms of SW development, writing flight software.

[–] CanadaPlus@lemmy.sdf.org 2 points 9 hours ago

Ah yes, assuming experience in your field basically translates to every other field. A tale as old as time.

[–] theacharnian@lemmy.ca 3 points 16 hours ago (1 children)

My understanding is that in space systems, generally robustness trumps everything else, so old stable versions of everything are preferred. So it's generally a very conservative software stack and process.

[–] pmirallesr@piefed.social 1 points 16 hours ago (1 children)

generally robustness trumps everything else

Theoretically

So it’s generally a very conservative software stack and process.

Yes, but that sort of process promotes non-adoption of techniques and processes that could increase robustness but are shunned due to pessimistic conservativeness

[–] theacharnian@lemmy.ca 1 points 16 hours ago

Oh yes absolutely. I was not trying to justify the design choices, just trying to explain their internal rationale.

[–] pmirallesr@piefed.social 2 points 16 hours ago

Yeah a fair bit of that too!

[–] reabsorbthelight@lemmy.world 12 points 21 hours ago (1 children)

Yeah, wtf is going on. GPG was released in 1999 and encryption existed before that too. https://www.ssldragon.com/blog/history-of-ssl-tls-versions/

How is this unencrypted

[–] tal@lemmy.today 8 points 20 hours ago* (last edited 20 hours ago) (1 children)

There was something of a to-do a couple years ago when some researchers were trying to see how strong encryption satellites were using and whether they could break it and discovered that a number of of satellite operators weren't bothering to encrypt things at all.

EDIT:

This might be more recent than that:

https://www.kratosspace.com/constellations/articles/the-state-of-satellite-encryption

A new study from the University of California San Diego (UCSD) and the University of Maryland has performed the most comprehensive public exploration into geostationary (GEO) satellite security yet, logging large amounts of unencrypted data being broadcast across 411 transponders on 39 GEO satellites, which were intercepted with a simple commercial-off-the-shelf satellite dish costing a few hundred dollars.

[–] reabsorbthelight@lemmy.world 6 points 20 hours ago

Wow. Amazing. I basically encrypt everything by default because I'm so paranoid. Sometimes multiple layers of encryption

That captcha is not letting me through no matter how many times I try.

Hate those multiple choice images, they're terrible captcha, or I'm a bot.

Which country is this available in, so I can use the right VPN.

It’s blocked with a Swiss and German IP.

Works in Finland

They probably saw the illegal tetris shape and had the shut down such transgressions fast. Can't have those fall down from above.

[–] Lysergid@lemmy.ml 1 points 21 hours ago (2 children)

Looks like it’s time to put some guns on satellites

[–] tal@lemmy.today 8 points 21 hours ago* (last edited 20 hours ago) (2 children)

The problem with kinetic kill anti-satellite weapons is that they create debris clouds. Unless the satellite is at a low altitude and about to de-orbit, that's generally bad.

https://en.wikipedia.org/wiki/Kessler_syndrome

https://en.wikipedia.org/wiki/List_of_space_debris_producing_events

Top debris creation events, August 2024

#1: Fengyun-1C 2007 3,549 fragments Intentional collision (ASAT)

EDIT: And apparently that debris cloud from that anti-satellite weapon test is believed to have taken out a Russian satellite:

https://en.wikipedia.org/wiki/2007_Chinese_anti-satellite_missile_test

In early 2013, the Russian concept satellite BLITS collided with what is believed to be a piece of debris from Fengyun-1C, was knocked out of its orbit and soon afterwards data retrieval from the satellite ceased.

[–] Lysergid@lemmy.ml 4 points 20 hours ago* (last edited 20 hours ago)

Kessler is inevitable. Today, no one will cancel satellite launch because others asked them not to. Since humanity is not capable of cooperating we will end up with satellites Cold War. We actually in it already. I’d rather let them learn the hard way and make them all crash, than use it for military advantage. Yeah, some satellites are useful like wildfire monitoring and GNSS, others are either flex or military. Maybe loosing all those useful one will make humanity cooperate and lunch only what really necessary in coordinated and transparent way

[–] bufalo1973@piefed.social 1 points 19 hours ago* (last edited 19 hours ago) (2 children)

Then maybe a rocketthat sticks to the target and pushes it out of orbit. Maybe down to the atmosphere if in LEO or away if geosync.

[–] Skua@kbin.earth 2 points 15 hours ago

No idea if anyone has done anything to make this more than an idea, but if you want to de-orbit someone else's satellite safely you could use a laser broom. Whe you vaporise stuff with a laser, the material that ablates off of the object imparts a bit of thrust to that object. This means that zapping a satellite with a laser can potentially slow it down just like pushing it with a rocket. It also has the benefit of being useable on any other troublesome debris, and it can be reused between jobs (assuming you solved the engineering challenges of Big Space Laser)

[–] theacharnian@lemmy.ca 2 points 16 hours ago

You're describing drone warfare in space. Neat..

[–] RememberTheApollo_@lemmy.world 2 points 16 hours ago

Need them to fire “parachutes” at satellites. The material will change the center of mass making the satellite difficult to control, obscure antenna and solar panels, and increase the small amounts of drag satellites experience causing them to use more fuel trying to correct orientation and de-orbit far sooner. No extra debris in orbit.
