FAQ
What is a spaceport?
A site built for launching and sometimes landing rockets. It includes pads, fuel storage, tracking radar, and downrange safety zones. Some, like Kennedy Space Center, are vast government complexes, while others, like Mahia in New Zealand, are compact commercial pads.
Why are launch sites often near the equator?
Launching eastward from the equator uses the full rotation speed of Earth, about 1,670 kilometers per hour, as free velocity. Kourou in French Guiana at 5 degrees north is the prime example and can carry up to 3 percent more payload than a launch from Florida.
Which launch site has hosted the most orbital launches?
Plesetsk in Russia has flown more orbital launches than any other site in history, mostly military satellites during the Soviet era. Baikonur in Kazakhstan launched Sputnik and Gagarin, and the Cape Canaveral complex in Florida leads in total tonnage to orbit and launch count today.
Can the public visit spaceports?
Yes. The Kennedy Space Center Visitor Complex is one of the largest museums in Florida. SpaceX runs limited Starbase tours, Kourou opens launch days to the public, and Baikonur can be visited through licensed tour operators with advance permission.
What was the first spaceport?
Peenemunde in Germany tested the V-2 from 1942 and is the origin of modern rocket ranges. White Sands in New Mexico launched the first American captured V-2 flights in 1946, and Baikonur became the first purpose built orbital cosmodrome in 1955.
What is a polar launch?
A launch flying north or south so the satellite orbits over the poles, letting Earth rotate beneath it. Polar sites like Vandenberg, Kodiak, and Mahia sit on coasts with clear southern or northern corridors and empty ocean or tundra downrange.
