$257 billion spent each year on Space Industry by Governments and Businesses

Most of the money ($257 billion) is spent on
– satellite TV ($70 billion)
– maintaining ground stations ($74 billion)
– $17 billion fixed satellite services
– $26 billion Department of Defence (military satellites and the spending around it)
– $17 billion NASA
– $10 billion national reconnaissance office (spy satellites and spending around it)
– $8.9 billion missile defense agency

The foreign government spending looks undercounted. It does not look like the foreign military or spy spending has been taken into account.

$5.6 billion on commercial satellite building
$2 billion on commercial launch systems
