Before a rocket even lights its engines, it’s already moving at about 900 mph, because the Earth is spinning. At the equator the ground moves at over 1,000 mph; at Florida’s launch pads it’s about 900, heading east. Staying in orbit takes around 17,500 mph sideways, so rockets launch east and keep that head start for free. That’s why America’s biggest pads sit on Florida’s east coast, where rockets climb out over the ocean, and why Europe launches from French Guiana, almost on the equator. Israel launches west, over the Mediterranean, and gives the boost up.
