- Missile early warning: Provides warning of an attack by detecting ballistic missile launches. Earliest known are Missile Defense Alarm System.
- Nuclear explosion detection: Detects nuclear detonation from space. Vela is the earliest known.
- Optical imaging surveillance: Earth imaging satellites. Satellite images can be a survey or close-look telephoto. Corona is the earliest known.
- Reconnaissance satellites have been used to enforce human rights, through the Satellite Sentinel Project, which monitors atrocities in Sudan and South Sudan.
- To operate a reconnaissance satellite, North Korea must launch a long-range rocket to put it into orbit.
- But the UN bans such a launch by North Korea because it considers that as a cover for testing its long-range missile technology.
