Re: Isn't it a bit far from the equator?
My (limited) understanding is that changing angle of orbit takes a lot of extra fuel fuel.
If you launch from the equator and want an equatorial orbit, all is fine and you can take advantage of the Earth's rotation. However, for any other orbit, you have to add an angle to transition from LEO to the final orbit and that is really expensive on fuel.
Starting from a latitude closer to the final orbit saves more fuel than you lose in take off...
(There are probably a lot of calculations involved - this is space after all!)
