A reference for launch sites.

Launch sites are badly served online. Wikipedia has an article for each famous pad and nothing for the other two hundred. The launch APIs carry the coordinates but publish no pages. So you couldn't ask how many rockets have flown from Vandenberg SLC-4E and get an answer anywhere in one piece.

Now every pad has a page: where it is, who runs it, what has flown from it, and how each of those flights ended. Sites collect their pads. Countries collect their sites.

What it counts

• A launch is a flight attributed to a specific pad in the source record. 7,651 of them have a decided outcome.
• A success rate divides successes by decided outcomes. Scheduled attempts never enter the denominator, and both numbers are shown beside the percentage so you can check the arithmetic.
• A partial failure counts as a failure in the rate and is labelled distinctly in the flight table, because the distinction is real.
• Cadence charts count decided flights per calendar year. Gap years are drawn empty rather than skipped, so a dormant decade looks dormant.

What it leaves out

• No countdowns and no live tracking. The data is rebuilt periodically and read as a record.
• No estimates. A missing input means the row is left out, rather than filled with a guess or an "N/A".
• No API and no JSON file to scrape. The upstreams do that better, and both are credited on the sources page.
