This site has its altitude going up very slowly !!?

Yes...it’s in an elliptical orbit, so it’ll gain altitude during half of the orbit.

Eventually, it’ll come into contact with the atmosphere on thew lower side of the orbit. That will slow it down enough that it can’t regain altitude. Then...’dos vedanya’.

[Jack Hydrazine]

That’s because it’s orbit isn’t perfectly circular.
