Are most Earth polar satellites launched to the South or to the North? And why?

Almost all satellites in LEO have been launched to the east, to take advantage of the Earth's surface rotational speed of about 5% of required orbital speed (Israel being a small exception for ...

Optimal turning from equatorial to polar orbit

Yeah, I know, "launch into target orbit". But let's assume we need to perform the maneuver. A satellite in LEO equatorial orbit would need excessive amounts of delta-V to enter polar orbit. The ...
