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

1. What is the theoretical foundation?Konstantin Tsiolkovsky's rocket equation, derived in 1903, mathematically describes rocket performance
2. What is the first liquid-fueled rocket launch?Robert Goddard successfully launched the first liquid-fueled rocket on March 16, 1926
3. How do rockets move up into space?They use Newton's Third Law: the engine shoots out hot gases fast, and the rocket pushes up the opposite way, giving it thrust.
4. What are the differences between solid and liquid rockets?Solid rockets are simpler but can't be turned off once started; liquid rockets can be controlled, turned off, and restarted, giving more flexibility.

Specific Impulse (Isp): A measure of rocket engine efficiency, indicating how much thrust is produced per unit of propellant consumed over time.
Liquid-Propellant Rocket: A rocket engine that uses liquid fuel and oxidizer, allowing for controlled thrust and restart capabilities.
Reusable Launch Vehicle: A spacecraft or rocket designed to be used multiple times, significantly reducing the cost of space access.
