I attempted to focus on why it is that the ISS is rotating in a RE model. I am also interested in the NASA conspiracy but maybe that's best done in a thread on that topic. Give me a link and I'll discuss it with you there.
Let me try again and see if I can correct my failure to explain why the ISS rotates. This is just a thought experiment.
Say you take a hunting bow and shoot an arrow into a basketball such that the tail end of the arrow is sticking out of the ball while the tip is lodged inside. Now you hold it so that the arrow is horizontal. You attach a string with glue to the top of the ball and let the whole thing hang motionless from the ceiling. Next you give the end of the arrow a nudge so that the whole thing rotates at say 1 RPM about the string axis. Now the tail feathers were pointing due east when you gave them a nudge. After 15 seconds they are pointing due south. After another 15 seconds they point due west. After the next 15 seconds they point due north. After 1 minute they are back where they started.
The whole time the tail feathers were pointing towards the ball. They rotated about the string axis with one revolution. If a tiny movie camera mounted to the tail end parallel to the string axis were looking up at the ceiling and recorded what it saw for that minute what would you see when you played it back on your monitor? You'd see a movie of a ceiling that spun around the point of attachment of the string to the ceiling.
Does that make sense now? If you can imagine all of this then the basketball is the earth, the tail feathers are the ISS, the ceiling is the star field. The only difference is that the orbital rotation of the ISS is not the same as the earth's rotation rate. The thought experiment would correspond more accurately to something in a geostationary orbit.
yes. I understand the metaphor and also how it equates with ISS and the apparent rotation of the stars in the sky.
Thanks for explaining it like that.
There are several threads about NASA general BS on this forum already.
I'll include a few links here -
