Whoa so many mind blowing facts. Does the orbit change or does the lens rotate? If one knos the rotation degree can the total number of satellites it would take to cover the entire earth be calculated?
It's highly unlikely that a satellite-based telescope would rotate/turn the lens. Turn it relative to what? It's in 0g, there's no part that's held in place by friction to the ground. Any rotating joint would make the two sides move in opposite directions. And if you think about that, let one side be much smaller, and allow rotating by multiple turns instead of just 0-360 or such, you might just invent the gyroscope.
They turn the whole satellite with gyroscopes (flywheels) and/or propellant.
