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 year of proposal?1978
2. What is the primary location of concern?Low Earth Orbit (LEO)
3. Why does space get crowded with junk?Space gets crowded because many satellites and rocket parts are left in orbit, and when they collide, they break into many smaller pieces that also stay in orbit.
4. How do collisions make more space junk?When two objects hit each other at very high speeds, the impact shatters them into many tiny fragments that spread out into new orbits, adding more junk and increasing the chance of more collisions.

Low Earth Orbit (LEO): The orbital region extending from approximately 160 to 2,000 kilometers above Earth's surface, characterized by high object density and operational activity.
Collisional Cascading: A process where collisions between objects in orbit generate numerous fragments, increasing the probability of further collisions and leading to an exponential rise in debris.
Atmospheric Drag: The resistive force exerted by Earth's atmosphere on objects moving through it, which can cause orbital decay and eventual re-entry.
Space Traffic Management: The coordination and regulation of objects in orbit to ensure safe and sustainable space operations.
