| 55% of all spacecrafts launched from 1957 to
2009 are military and 45% are civilian. (See Table
4 - Civilian vs. Military Spacecrafts and the lists of all Civilian
Spacecafts and of all Military Spacecrafts.)
Military spacecrafts could be classified in three
broad categories:
| • |
applications (surveillance ("spy") activities) |
| • |
services (communications, navigation, etc.) |
| • |
technology development. |
Applications represents 50% of all military spacecrafts
launched, services count for a third and technology for the remaining one-sixth.
(See Table 9 - Military Families Statistics.)
Civilian spacecrafts could be classified in three
broad categories:
| • |
space exploration (piloted, science, planetary,
astronomy, etc.) |
| • |
applications (communications, meteo and Earth-remote
sensing) |
| • |
technology developments |
Two-fifth of all civilian spacecraft pursue space
exploration, nearly half are for applications and the remaning one-tenth
are for technology development. (See Table 8 - Civilian
Families Statistics.)
