I understood that ISS window always faces the Earth. Wouldn't it happen if ISS was hypothetically fired in one piece around the Earth (window pointing to Earth at the start) without any further intervention (propulsion, gyro ...) ?

    $\begingroup$ I think you are asking "Would the ISS maintain a nadir-facing cupola attitude if attitude control systems were turned off?" Is that another way to express your question? $\endgroup$

    $\begingroup$ I edited my question with picture and with deepest excuse for my bad drawing. So would it be object's trajectory or window would always point toward the Earth. $\endgroup$

    $\begingroup$ Does this answer your question? Why does the ISS points always the same side towards the Earth? $\endgroup$

    $\begingroup$ @uhoh It's unclear to me the level of detail that is being asked for, hence I just wrote a comment. Feel free to write an answer, as the level of detail approaches the "quadrupole moment" regime, I bow out. $\endgroup$ Dec 16 '19 at 13:22

    $\begingroup$ @uhoh there are some old ones here athena.ecs.csus.edu/~grandajj/ME296M/space.pdf The "latest" starts on pdf page 325. $\endgroup$ Dec 16 '19 at 17:20
