The planet rotates fastest at its middle, and that eastward spin - a little over 1,670 kilometers per hour at the equator - adds velocity to any launch headed east toward orbit. Engineers have known this for decades; it is the same physics that led the Europeans to build their spaceport in French Guiana and the Americans to favor Cape Canaveral. On the rust-red bluffs above the Atlantic coast of Maranhão, the Brazilian Air Force built Alcântara to claim that same advantage. It is the closest orbital launch site to the equator anywhere on Earth.
