There is nothing in the article you linked that explains why "low temperatures and the complex, ever-changing dynamics of sea ice" used to make the region "virtually inaccessible to satellites" but now no longer does.
Further, I did a search using "challenges of satellites in the Southern Ocean" and found no info, rather than plenty of info.
edit: I eventually found the following link which does seem to discuss some challenges, but does not indicate that they have been solved. It certainly does not support the claim that the region is "inaccessible to satellites".
I did something similar, but I mapped it (on hold) to cmd + control + option + shift so it effectively becomes a new modifier key that I use to define shortcuts that will never clash with any existing shortcuts. I use it to launch / switch to specific apps, move windows, etc.
If the Notion timeline view had more granularity (hours and not just days), it would become a great tool to plan novel scenes! (I’m using Aeon Timeline for now, but it’s clunky and doesn’t get any updates. I’d switch to Notion in a heartbeat!)
An explanation from one of the sides. There are many things in that text that could be discussed. For example, the "attacks against the education system and linguistic rights". I dare you to explain that in detail.
If you want to understand the challenges of satellites in the Southern Ocean, there's plenty of info about it online.

(I am also non an expert, and I also didn't understand it at first. That's to be expected. The real world is complex and hard to understand.)
