Launch Pad Challenge: Define & Imagine

Focus Question: How do engineers define a problem and generate multiple possible solutions?

Mission Briefing

Today’s Plan

Every task advances the same Rocket Launch Pad Design Challenge.

Learning Targets

  • Explain how the Engineering Design Process will guide the Launch Pad Challenge.
  • Identify the challenge criteria and non-negotiable constraints.
  • Create three annotated concepts that solve the same problem in meaningfully different ways.

Success Looks Like…

Your team has a concise design brief and three understandable concepts that another student could interpret without a verbal explanation.

Project connection: Your work today becomes evidence used in the next stage of the Engineering Design Process.
Challenge Reveal

Design a stable launch pad for the provided rocket

The project is intentionally constrained so your engineering effort can focus on structure, stability, and decision making.

Mission

Your engineering team will design and build a tabletop launch pad.

The launch pad must securely support the instructor-provided rocket in an upright position, remain stable during qualification testing, and be built only from the standardized team material kit.

The rocket is provided. Do not modify it.

Artemis launch vehicle and mobile launcher
Real launch systems use structure, bracing, access, and carefully planned interfaces. Look for ideas you can adapt at classroom scale.
Engineering Design Process

The project is the process

You are not memorizing a sequence before the project. You will experience the process by completing the challenge.

Today: understand the problem, identify what cannot change, then create options.

Challenge Requirements

Know the rules before sketching

Size

Maximum launch-pad footprint: 12 in × 12 in.

Maximum pad height: 12 in, not including the rocket.

Rocket Interface

Use the provided rocket. It may not be cut, drilled, glued, taped, or otherwise modified.

The rocket must be removable without damaging either item.

Function

The launch pad must be freestanding and hold the rocket upright without being held.

It must remain functional after qualification testing.

Materials

Use only the standardized team material kit and approved joining methods.

You are not required to use every material.

Standardized Material Kit

Every team starts with the same resources

1 × 12 in × 18 in foam board20 craft sticks10 straws48 in stringHot glue as needed

Engineering habit: Material is useful only when it contributes to function. Do not add parts simply because they are available.

Design Brief

Define the engineering problem

Criteria — goals to improve

  • Stability
  • Secure rocket support
  • Compact footprint
  • Easy rocket installation/removal
  • Efficient use of limited materials
  • Clear, buildable construction

Constraints — rules that cannot change

  • 12 in × 12 in maximum footprint
  • 12 in maximum pad height
  • Provided rocket; no rocket modification
  • Standardized material kit only
  • Freestanding structure
  • Must pass required qualification tests
Concept Generation

Create three different structural approaches

Do not draw the same idea three times with cosmetic changes.

Every sketch should show:

  • Base shape and approximate footprint
  • Rocket location and support method
  • Major structural members and bracing
  • Approximate overall dimensions
  • Which provided materials are used where
  • Labels explaining why important features exist

Quality check: Another team should be able to understand the concept without you standing beside it.
