Absolutely debunked, FAA accepted a report that didn't do proper research and have been called out by SpaceX for it.

[–] [email protected] 57 points 1 year ago (1 children)

Someone downvoted you but you are correct. The report used assumptions based on satellites not even made of the same materials as starlink satellites.

https://arstechnica.com/tech-policy/2023/10/spacex-says-faa-is-wrong-about-starlink-satellite-debris-falling-to-earth/

Among other things, SpaceX said the FAA's debris estimates were based on a 23-year-old study of satellites that were made with different materials than Starlink satellites. SpaceX says its own satellites are designed to burn up completely when they reenter the atmosphere.

The FAA report to Congress did include a caveat that said, "If SpaceX is correct in reporting zero surviving debris, as SpaceX reports in FCC filings, and Starlink is a fully-demisable spacecraft, the rise in reentry risk is minimal over the current risk."

“If SpaceX is ~~correct~~ honest in reporting zero surviving debris, as SpaceX reports in FCC filings, and Starlink is a fully-demisable spacecraft, the rise in reentry risk is minimal over the current risk.”

[–] [email protected] 19 points 1 year ago

Yeah, I was going to say that there is no way that could be correct. There are only like 8000 satellites in orbit. There is no fucking way that small of a number is going to be hurting someone every couple years.

[–] [email protected] 14 points 1 year ago

The people that put sats up have to calculate how every component will burn up in the atmosphere before they even get approval. Simply put, there's basically no chance of anyone dying from these things reentering the atmosphere.

[–] [email protected] 1 points 1 year ago (1 children)

Lol SpaceX. Why would I take them seriously?

[–] [email protected] 12 points 1 year ago (2 children)

Who wouldn't? They are doing some of the most advanced rocket science on the planet. Of course, trusting corporations statements and research is an entire topic of it's own. Taking Elon Musk seriously on the other hand...

[–] [email protected] 2 points 1 year ago (1 children)

Because they are a corporation that is actively littering LEO with hundreds of satellites, and fear economic retribution and/or responsibility as a consequence of this kind of information?

You see how there might be something called "conflict of interest?"

Having a conflict of interest does not mean they aren't competent at what they do - just that they have reason to be biased against information that may result in direct consequence.

[–] [email protected] 0 points 1 year ago (1 children)

While SpaceX does launch and operate thousands of satellites, this also means that they stand to lose the most if LEO becomes cluttered with space junk. If anyone ought to be worried about space junk, it is the launch providers. If space junk becomes a problem, their customer base vanishes.

Ok Thre-ElonMusk-eteers.

You keep gobbling that knob. Maybe daddy will pay attention to you one day

Wow, I've never heard about "GIZCHINA". It definitely isn't gizmodo - right? 🤔 Right!

  • it is a Czech company with entire capital stock consisting of 4USD 😎 (cca 100 CZK)
  • the text is showing hight probability of AI generation. Which adult human being is going to write eg: " In this article, we will discuss the FAA report in detail, including the risks posed by falling satellites, the causes of these risks, and the potential solutions to mitigate them." 🤖
  • it does not say anything else than this - much more likely human written thing here - only the original is only 1/3 as long. That is IMO how come the AI Writing is literraly jumping out on you from the article. 😱

This is my least favourite century yet.

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago)

TBF the original article you linked is in Chinese and does not have ads in the middle of the article, so you should compare their translated lengths.

All in all we need the original FAA report.

Edit: Ars Technica is way more useful as always.

The thumbnail image isn't even a satellite...

The dragon capsule isn't going to suddenly fall out of orbit somewhere unexpected...

The dragon capsule isn't going to suddenly fall out of orbit somewhere unexpected...

It's highly unlikely, but the possibility isn't 0. Like, what if an untracked asteroid hits it out of orbit?

[–] [email protected] 4 points 1 year ago

There are around 50,000 Starlink near misses per year.

[–] [email protected] 3 points 1 year ago

Well, the chance isn't zero, but that example, being knocked out (disabled or destroyed) by an asteroid has never happened to any spacecraft, ever. Statically the chances of that happening are very very close to zero.

Injure? Injure?? If someone gets nothing but a boo boo from a falling fucking satellite then they need to go buy a lottery ticket right away.

[–] [email protected] 14 points 1 year ago

It can hit in someone's vicinity causing them injury. It would rarely be a direct strike.

[–] [email protected] 9 points 1 year ago

Satellites will have thoroughly fragmented by the time they reach the ground, you'd be hit by a piece of a satellite.

Assuming the study being referenced wasn't actually badly flawed, which it appears to be.

[–] [email protected] 7 points 1 year ago

One can get hurt without a direct hit. E.g. when a window bursts from a shockwave and hurts people inside a building.

[–] [email protected] 4 points 1 year ago* (last edited 1 year ago) (2 children)

I recommend you never buy a lottery ticket - because clearly you don't understand how luck works.

If a satellite were to smash through the roof of my office and land harmlessly on the floor, I reckon I'd be quite startled and might bump my knee on the bottom of the desk...

There's definitely a risk of injury, and you're far more likely to be injured than killed.

I'd probably also have to pay a couple hundred thousand dollars to repair my home, since I don't think insurance covers falling satellites and I'm certainly not going to try and sue a company on the other side of the world when they probably didn't do anything against the law anyway. Bruised knee would be the least of my problems.

[–] [email protected] 5 points 1 year ago (1 children)

The lottery chances are independent of the other event I believe so why not go for it

[–] [email protected] 3 points 1 year ago

With my luck, I'd buy the winning lottery ticket and then get hit by a satellite the following day.

[–] [email protected] 3 points 1 year ago (1 children)

Nah, if a satellite crashes through my roof, I'm definitely gonna be a first time lottery ticket buyer that day.

[–] [email protected] 4 points 1 year ago

Why? Wouldn't you have spent all your luck for that day?

[–] [email protected] 21 points 1 year ago* (last edited 1 year ago)

the probability that the satellite debris will not be completely burned during the fall and cause injury or death to people on the ground is 0.6 per year. This means it would happen once every two years

That doesn’t mean it will fucking hit someone. The surface area of the planet is 510e12 m^2. There are about 8B people on the planet. Even if we conservatively assume that everyone is lying flat on their back in the middle of an open field, that’s only about 8B m^2 of vulnerable surface area. At that rate, you’d expect an injury interval of 510e12 / 8e9 / 0.6 = 1 injury every 106 thousand years. Yes there is some correlation of common orbits and human population, so we can be conservative and put it at 50,000 years.

Do we know who this 'someone' is? Sucks to be them.

[–] [email protected] 9 points 1 year ago

This completely ignores the fact that the 2034 Full Self Driving beta release roadmap includes falling satellite avoidance capabilities.

[–] [email protected] 8 points 1 year ago

This article was either written by AI, or a human with an IQ of 50

[–] [email protected] 7 points 1 year ago

So far, no one has ever been killed by a meteorite. There's been a scary injury, some unconfirmed rumors and at least one engine block was cracked in half.

That said, death by thing falling from space is totally how I want to die. Bonus points if I'm totally disintegrated and just MIA. ( Circuitboard. It was man made. Has anyone seen Uriel? ) A falling satellite will be fine.

[–] [email protected] 5 points 1 year ago

Perhaps fetching all of that junk might be a good idea? Perhaps a satellite trash collector satellite.

[–] [email protected] 3 points 1 year ago (1 children)

I’ll just stay inside that day, or better yet go hang out in a tunnel

[–] [email protected] 8 points 1 year ago (1 children)

Wait until you hear about Boring Company 's rogue tunnel diggers...

[–] [email protected] 2 points 1 year ago (1 children)

In 2034 once every two years, a person will end up in a randomly dug tunnel.
