Write the rule before you need it.

Showing stage 1 of 7: Mission
Mission
When a fault happens, nobody on the ground can react in time. Whatever the spacecraft does next was decided months earlier, by whoever wrote its rules. Your team will read a mission that went wrong and write the rule that should have been there.
The spacecraft met a fault it had no rule for. What should the rule have said?
- Your role
- Autonomy and fault-response engineer
- Objective
- Use modeled fault evidence to write one testable condition-and-action policy rule.
- Success looks like
- Run the fault case, find the decisive transition, select evidence, write a concrete rule, and acknowledge its cost and validation limit.
Learning outcomes · University
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 design a safe mission policy that holds under the fault this run experienced, and demonstrate this by stating the condition, the action and the evidence each rests on.
- 02By the end of this mission, the learner will be able to assess what this deterministic operations run establishes about policy safety and what it withholds, and demonstrate this by classifying the channels correctly.
- 03By the end of this mission, the learner will be able to validate the limits of treating a policy tested in this runtime as safe to fly, and demonstrate this by stating the qualification evidence that would still be required.
Preparation
Before we start
A quick check of what you already know. There is no score.
The idea behind the mission
A mission policy is a set of rules written in advance: when this condition holds, take this action. The spacecraft follows them alone.
Rules are written in advance
A spacecraft cannot ask for help in time. Every response to a fault has to be written before launch, as a condition the spacecraft can test and an action it can take. A general instruction to be careful is not a rule. A condition the spacecraft can test, paired with an action it can take, is.
Predict before you run
Before you look: what do you think a spacecraft should do first when something goes wrong, and why?
What should a spacecraft do first when something goes wrong, and why?
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.
- Mission objective and success criterion reviewed: not done yet
- Preparation diagnostic answered: not done yet
- Mission theory reviewed: not done yet
- Prediction recorded: not done yet
The set-up you will run
This is the set-up you will run. It is fixed on purpose, so everyone in the class is reading the same evidence.
Baseline case
This mission
- Write your prediction first.
- Find when the fault took hold, not just that it did.
- These readings come from a model, not from a real mission.
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.
Run the mission and collect its readings.

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
Find the moment things changed, then ask what a rule could have checked before that point.
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
What does your safety rule cost the mission, and how would you test that the rule does not create a new hazard?
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: the rule you already follow
Write down one rule you follow without thinking, as a condition and an action - for example, if the battery reaches ten per cent, stop watching video. Then write what it costs you, because every safety rule costs something.
