Here’s an article at the WaPo about it. This isn’t correct, though:
It is always desirable to launch to the east to capitalize on the direction of the Earth’s spin. The Earth travels about 1,000 mph west to east at the equator; you need to reach a speed of 17,000 mph to get to low-Earth orbit, so there’s no point in penalizing yourself 1,000 mph by heading in the wrong direction.
No, not “always.” Only for low-inclination orbits. For very high inclination, or retrograde, it’s actually preferable to launch from a high latitude (ideally, for a retrograde orbit, you’d like to launch from a pole, to eliminate any earth rotation, because it’s rotating in the wrong direction).
