I can explain how mechanisms support aerospace systems and identify where force, motion, energy, and power appear in a design challenge.
POE Unit 1 • Lesson 1.1
Unit Launch: Mechanisms for Space Missions
Focus question: How do mechanisms support aerospace missions by changing force, motion, energy, or power?

Lesson Targets
What You Will Be Able to Do
Aerospace mechanism systems map
The system map names the input, mechanism, output motion, mission task, and evidence that would prove performance.
Activity Flow
How the Lesson Moves
This page highlights the lesson elements you need for practice, evidence, and submission.
1. Analyze a mission mechanism
Identify what moves, what supplies energy, and what useful task is completed.
2. Trace the system
Follow energy and motion from the source through the mechanism to the final output.
3. Define proof
Choose a measurement or observation that could verify the mechanism worked.
Lesson Interactive
Trace the Rover Lift System
Classify each component by its role in the system, then use the completed chain to identify where energy is stored, converted, transmitted, and used.

Today’s Work
Main Deliverable
Aerospace Mechanism Systems Map
Create one systems map for an aerospace mechanism or rover subsystem.
- Label the energy source, input motion, mechanism, and useful output.
- Identify one testable performance measure such as lift force, travel distance, speed, or deployment time.

Mission Debrief
One way today’s lesson connects to an aerospace mechanism or VEX rover system.
One type of evidence you could use to support a design decision.
One question you still have about mechanisms, energy, power, or the Unit 1 challenge.
