Senario Based
Your objective is to send a probe to Mars. Which combination of engines would you use to escape Earth's atmosphere and then navigate in space?
A chemical rocket for launch and an electric or ion engine for deep space travel
This force pulls everything, including airplanes, toward the ground.
Gravity
Name 2 main components of a Chemical Rocket Engine?
Any 2:
Combustion chamber: where fuel and oxidizer burn
Nozzle: directs exhaust gases to create thrust
Injectors: mix fuel and oxidizer
Turbopumps: pump propellants
under pressure
Propellant tanks/feed system
Ignition system and valves
This is the tool astronomers use to observe distant stars and planets by collecting light.
Telescope
Who is our Club Supervisor?
Mr. Steven Zhang
Your mission is to launch a satellite into low Earth orbit. What type of engine would you primarily rely on during the launch phase?
A chemical rocket engine
This force opposes gravity and allows an aircraft to stay in the air
Lift
How does the cooling system work in Rocket Engines?
What is the farthest planet from the Sun
Neptune
What breed was the first dog that launched into space?
A stray mixed-breed named Laika
When should you use a chemical rocket engine?
When you need to generate a large amount of thrust quickly
(any scenario that fits that)
This force pulls an airplane backward as it moves through the air
Drag
What is a spacecraft engine?
A spacecraft engine is a propulsion system that moves a spacecraft by expelling mass to generate thrust.
The purpose of a spacecraft engine is to provide propulsion for launching, navigating, and maneuvering in space. Different engine types are used based on mission requirements.
This is the closest star system to Earth, located about 4.37 light-years away.
Alpha Centauri
What does NASA stand for?
Explain two principles of ion propulsion and when it would be advantageous to use this type of engine over traditional chemical rocket engines.
State any 2:
Principles:
- Ionizes a propellant (e.g., xenon)
- Accelerates ions with electric fields for thrust.
Use Cases:
- Ideal for long-duration missions and deep-space exploration.
- Requires less fuel, enabling longer travel with reduced launch mass.
What is it called when an object has reached its top speed (when falling), where the forces of thrust and drag are balanced?
Terminal Velocity
Name one Advantage and one Disadvantage of Chemical Rocket Engines
What is the term for the boundary surrounding a black hole beyond which no information or matter can escape, and what is its significance?
The event horizon
What is the name of the mission and rocket that was the first to send mankind to the moon?
Apollo 11 Rocket: Saturn V SA-506
Your objective is to launch a probe into deep space. What combinations of engines would you require?
high-thrust chemical rocket engines for initial launch and escape from Earth, followed by highly efficient, low-thrust electric propulsion systems for deep-space acceleration
Identify 3 variables used in the equation for thrust.
Name the element group of gases commonly used in electric rocket engines and provide 2 examples of specific gases from that group.
Name ALL of the main Greek-adjacent gods that the planets were named after. (5 total)
Bonus points if you can name the role of said gods/goddesses
Mercury (Hermes)
Venus (Aphrodite)
Mars (Ares)
Jupiter (Zeus)
Neptune (Poseidon)
