Is there a room without gravity?

The truth is that even spaceships tend to lose altitude (like the satellites) after a while and track corrections must be made

In order to stay in orbit and not fall into Earth.

Even the moon is not really fixed orbit, but it is moving away from us about 2.5 cm every year (if I remember correctly)

I'm not sure if this is the distance, but in general you're right. In a few tens of thousands of years we will not have a moon, the day will be 6 hours and all the time there will be very strong winds, creatures will come with shields and it is doubtful we will be (I estimate that we will be because until then the technology we will be able to change the weather completely, Yes we can create an artificial moon :P).

Loss of height is not just about gravitation. Most satellites (up to a few thousand kilometers) lose speed and height due to friction with the atmosphere, and there are other external influences such as micrometeorors and solar wind.

There is no connection between moon distancing and changes in the orbit of satellites. The Moon is moving away because of an angular momentum change between the two bodies, which is due to the slowing down of Earth's rotation, mainly due to the tide.

Low Earth orbit (LEO) satellites are still in the atmosphere, so drag-and-run satellites (MEO) and geostationary orbit (GEO) satellites are not in a place to be dragged, but due to gravity anomalies are attracted to certain places, East / west or north / south, and this requires route corrections.

I talked about such reactions, not about the quote of Newton's laws ...

With all due respect to high school physics (and some university) I have, it is clear that the man knows what he is talking about.

A degree in physics is very suitable for space, missiles and aeronautics. Although I do not know if it requires a master's degree or you can enter these fields with a bachelor's degree only. The classic title for the field is aeronautical engineering or mechanical engineering in aeronautics, which is about the same.

As for this issue, I happen to know the field and am very interested in it. I study mechanical engineering and my direction, hopefully, is Or renewable energy. In the meantime, big dreams :)

It's such a pleasure that we will not be here to watch it :o
