Main factors: - Safety. You want rockets to safely travel over unpopulated areas - for both accident scenarios and so that intermediary booster stages can just fall - Speed boost from Earth’s rotation. The closer to the equator the better.

Nice call, Joao. But I think the second factor regardless the rotation orientation, right?

They would have to make a left-handed rocket as well, made with left-handed screwdrivers.

Having a launch site back home in Portugal would be awesome, but if Earth rotated clockwise it would probably mess the Gulf Stream and we would end up with a climate similar to New York...

There is a spaceport coming to Azores, will also work if Earth decides to spontaneously flip rotation axis

If the earth moved the other way then France nor the USA would be where they are.

Israel is the only country that launches the "wrong" way already due to their conflict with neighboring countries.

@Luismirubin qué dices? -
Si la tierra rotara en sentido horario (visto desde el polo norte), convendría tener los launch sites en las costas oeste, por seguridad de Downrange. No concuerdo en la segunda afirmación. Para órbitas GEO facilita que el launch site esté lo más próximo a la línea del ecuador.
