Showing stage 1 of 7: Mission
Mission
A spacecraft design is a set of promises that all have to be kept at once: enough power, enough storage, mass within limit, balance within tolerance. Your team will put two designs through the same mission and check every budget, not just the ones that pass.
Two designs, one mission. Which one actually closes every budget it has to?
- Your role
- Spacecraft configuration engineer
- Objective
- Evaluate two declared configurations against every modeled mission budget and choose which can proceed.
- Success looks like
- Compile both configurations, inspect every check, select evidence, and avoid presenting declared-input budgets as CAD or measured truth.
Learning outcomes · Grades 11–12
What you should be able to do, and the evidence that shows it.
- 01By the end of this mission, the learner will be able to analyse how power, mass and storage budgets constrain one another in a spacecraft design, and demonstrate this by tracing one constraint through to another.
- 02By the end of this mission, the learner will be able to evaluate which design better meets a stated mission need, and demonstrate this by justifying that judgement against the validation checks.
- 03By the end of this mission, the learner will be able to formulate a bounded configuration recommendation and state its verification limit, and demonstrate this by naming the physical test that would be required to confirm it.
Preparation
Before we start
A quick check of what you already know. There is no score.
The idea behind the mission
Two designs, the same mission. Each is checked against its own stated limits, and every check has to hold.
Every budget has to close
Spacecraft design is constrained on several axes at once. A design with generous power can still be stopped by mass, or balance, or storage. Engineers check each budget against a stated limit and treat any one that does not close as a blocker, however comfortable the others look.
Predict before you run
Before you run anything: which design do you expect to close every budget, and which check worries you most?
Which design will close every budget, and which check worries you most?
At least 20 characters — say what you expect and why.
Readiness
This is a local preparation check. It is not Challenge qualification and creates no official attempt.

- Preparation diagnostic answered: not done yet

The set-up you will run
These are the two set-ups you will compare. They are fixed on purpose: if only one thing differs between your runs, anything that changes was caused by it.
Baseline case
1U trainer design
Candidate case
3U engineering design
- Write your prediction first.
- Both designs face the same mission, so any difference is the design.
- These budgets are computed from declared inputs. Nothing here is CAD truth or a measured subsystem.
Units stay attached to every result: angles in degrees (°), time in seconds (s), power in watts (W), energy in watt-hours (Wh), battery state in percent (%), and elevation in degrees (°) where available.
Finish every preparation item above first; then this can be confirmed.
Official qualification: false. This acknowledgement stays in this browser.
Operate
Readiness required
Complete every preparation requirement, then confirm readiness before operating the Twin.
Compile the trainer design first, then the engineering design. The mission is identical.
Baseline
1U trainer design
Candidate
3U engineering design
Run the baseline first so you have something to compare against.
- 1U trainer design: not run in this session yet
- 3U engineering design: not run in this session yet
Evidence
Run a Digital Twin case first
The results fill in once the Twin has produced evidence. The decision, limits and knowledge check can be read now.
Read the evidence
Read every check, not the headline. One budget that does not close is enough to stop a design.
Run the Twin to produce evidence.
Complete
Readiness required
Finish the required run or comparison, select evidence, make a decision and answer the knowledge check. Then reflect here and finalize.
Completion records the work you did; it does not mean mastery, qualification, or an official grade.
Reflect
Which constraint bound first, and what would you change without breaking a different budget?
At least 20 characters. Editing this or any source work after completion invalidates the local record.
Your formative result
Revisit the mission evidence
Formative · not an official grade
No formative evidence has been recorded yet.
Formative band: revisit. Any formative band may complete the mission. Official grade: none.
Finish the required run or comparison, select evidence, make a decision, answer the formative assessment, and complete your reflection.
Recognition
Lane C provides a private local-practice record. Verified recognition remains a separate Platform workflow.

Home mission
Home mission: four constraints at once
Plan a day trip with a fixed budget, a fixed amount of time, a bag with limited space and a train you must not miss. Write down which constraint binds first, and what you would change to relieve it without breaking the others.
