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 entry velocity regime?Hypersonic, typically Mach 25 to Mach 40 for Earth re-entry
2. What is the primary heat dissipation mechanism?Ablation of specialized heat-resistant materials
3. Why does an aeroshell need to be shaped like a blunt body?The blunt shape creates a shock wave that stays away from the vehicle, pushing the hottest part of the superheated air farther from the surface, so the spacecraft stays cooler.
4. How does an aeroshell keep a spacecraft from burning up during re-entry?The aeroshell uses a process called ablation, where the outer material chars, melts, and turns into gas, taking heat with it and keeping the inside safe.

Hypersonic Velocity: Speeds exceeding Mach 5, where air effects become highly complex and energetic.
Standoff Shock Wave: A shock wave that forms at a distance from the vehicle's surface, deflecting the hottest plasma.
Thermal Protection System (TPS): Any system designed to protect a spacecraft from extreme temperatures during atmospheric entry or re-entry.
