No. None are space junk and none were made nonfunctional by the storm. 1. The storm caused the atmosphere to expand 2. which increases drag on satellites. 3.

No. None are space junk and none were made nonfunctional by the storm. 1. The storm caused the atmosphere to expand 2. which increases drag on satellites. 3. The satellites were in safe mode because of the storm, so… 4. some satellites fell out of orbit because they couldn’t produce enough thrust to recover after the storm No satellite was ever even at risk of becoming space junk. This is pretty read TFA stuff.

Is there any way they are being held accountable/is there open data to support assertions of the article in question?

  This is also fairly well-known physics. We know what the atmosphere is like at those altitudes and we know what a starlink satellite looks like. Anything that sits around there is going to fall out of orbit pretty fast unless it has active thrust. Several governments have space-object tracking systems that work on stuff far smaller than starlink satellites - the US, the EU, Russia, probably China. I doubt that’s open enough for you, though. Frankly it doesn’t seem to me like there much to hold spacex accountable for. They’re out ~$35mm, but it’s harmless to the rest of us.

I doubt that’s open enough for you, though. I think it’s entirely reasonable to ask for data to back up SpaceX’s assertions and to feel concerned about it not being furnished. This is how proper science and engineering works. We don’t merely take press releases at face value.

  The orbital data of all satellites is publicly available. It is calculated by the US space force (formerly US air force) spacetrack https://en.wikipedia.org/wiki/United_States_Space_Surveillance_Network https://en.wikipedia.org/wiki/United_States_Space_Surveillan... . You can get the data via several public websites. Here for example are the current orbital elements of all starlink sats in JSON format: https://celestrak.com/NORAD/elements/gp.php?GROUP=starlink&FORMAT=json https://celestrak.com/NORAD/elements/gp.php?GROUP=starlink&F... This is raw data. If you want somebody that processes this data into easily digestable graphs, that also exists.

Propagation libraries for most major language exist. Here is a display of all active sats, using wasm and rust that I did as a toy: https://rklaehn.ddns.net/allsats/ https://rklaehn.ddns.net/allsats/
