Thank you for the Info. I changed the Category from "Internet and Funk" to "Radio, Broadcast, Wireless and Internet".
I mean Satellites and Rover for that like Starlink or TV Satellites.
"Funk" is the German word for Radio/Wireless. I am not sure, why I used it for the Forum-Category Name. Maybe it was to late 
the ISS is old but the end is not near.
The first Modules was bring 1998 into Space. That means, some Modules are over 20-25 years old. You need to understand: 20-25 Years old electric and life support Devices.
Originally, operation of the ISS was planned until 2020 at the latest.
The first plan was to bring back the Modules, with the Space Shuttle to Earth. But this was canceled because the Space Shuttle was stopped.
The next plan was to let the individual modules fall to the ground and let them burn up in the air. I am not 100% sure if this was canceled too. Maybe not for all Modules?
Russia want to use his own Modules for his new Space Station, they are building.
NASA ordered the Company Axiom Space for continued operation of the space station as a commercial product. So the era is not end 
And we are building a new space station with the Artemis Program but this time around the orbit of the moon -> Lunar Gateway
No, we do not have any fact-checked Information about the history of Mars, because we was not there and no one created any books 
On Earth, we drill holes and analyze the individual layers of rock, to find out, what was happening on the layer and in this year. We mostly do that in Antarctica
The Mars Rover "Perseverance " will drill the holes: https://en.wikipedia.org/wiki/Mars_2020
With Mars Sample Return Mission we want bring back the Martian rock to Earth.
At the Moment, we can only thing about what happend.
I do not know any good English Documentation about the Mars but "Terra X" here in Germany is very good.
