Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary detection mechanism?Infrared sensors detecting thermal emissions from missile launches, spacecraft, and nuclear events
2. What is the orbital configuration?Geosynchronous orbit, providing persistent surveillance over specific regions
3. How do DSP satellites find rockets and bombs?The satellites have infrared cameras that look for the hot glow of rocket flames and nuclear blasts. They spin and scan the Earth about six times a minute, so they can spot a launch quickly.
4. Why do DSP satellites stay in the same spot over Earth?They are placed in a special orbit called geosynchronous orbit, which keeps them over the same area. This lets them watch that region all the time without moving away.

Infrared Reconnaissance: Using sensors to detect heat signatures for intelligence gathering and threat detection.
Geosynchronous Orbit: An orbit where a satellite's orbital period matches Earth's rotation, appearing stationary from the ground.
Satellite Early Warning System: A network of satellites designed to provide rapid detection of ballistic missile launches and other strategic threats.
Strategic Deterrence: The military strategy of preventing an attack by threatening retaliation, often involving nuclear weapons.
