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 propellant ignition mechanism?Spontaneous ignition upon contact between fuel and oxidizer components
2. Why do rockets use hypergolic fuels instead of other fuels?Hypergolic fuels ignite instantly when the fuel and oxidizer touch, so they don't need a separate spark, making them reliable for quick launches.
3. How do workers keep the hypergolic fuels safe in the facility?They use special tanks, gas blankets, and careful transfer lines to keep the fuels from leaking or reacting early, following strict safety rules.

Specific Impulse (Isp): A measure of how efficiently a rocket engine uses propellant to generate thrust.
Turbopumps: High-speed pumps used to deliver propellants to the rocket engine combustion chamber at high pressure.
Thrust Vector Control (TVC): A system that allows the direction of a rocket's thrust to be altered, enabling steering.
