Who you are, what you are finding out, and what success looks like.
Showing stage 1 of 7: Mission
Mission
This mission came home with almost nothing. The spacecraft was healthy at launch, the payload worked, and the ground station was listening - and still, hardly any data arrived. Your team has the mission readings. Work out what happened.
The payload worked and the data never arrived. What stopped it?
- Your role
- Mission operations investigator
- Objective
- Trace the modeled failure sequence and recommend one policy change that addresses the decisive cause.
- Success looks like
- Run the mission, connect battery state to safe mode and delivery loss, select evidence, and propose one justified change.
Learning outcomes · Grades 9–10
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 quantify the shortfall between the data collected and the data delivered, and demonstrate this by reporting the difference with units.
- 02By the end of this mission, the learner will be able to model why an always-on policy exhausts a resource that a selective policy would preserve, and demonstrate this by relating the policy text to the readings.
- 03By the end of this mission, the learner will be able to test whether this mission met a stated delivery requirement, and demonstrate this by comparing the delivered figure against that requirement.
Preparation
Before we start
A quick check of what you already know. There is no score.
The idea behind the mission
One mission, one set of readings. Everything you need to explain the failure is in them.
Collecting is not delivering
A spacecraft that fills its storage has achieved nothing until the data reaches the ground, and sending it takes power. A policy that collects at every opportunity can drain the battery so far that the spacecraft protects itself by shutting things down - and then it cannot send anything at all.
Predict before you run
Before you look: what do you think a spacecraft is most likely to run short of, and what would happen next?
What do you think this spacecraft ran short of, and what would happen next?
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.
- Read every reading before deciding; the obvious one is not always the cause.
- 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
Follow the battery down and see what changes when it gets low. Then look at what was collected against what was delivered.
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 clue separated the root cause from the most obvious symptom, and what evidence would confirm it in a real mission?
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 flat phone
Think of a time a phone went flat before you could send something. Write down what was being used up, what warned you, and what one habit would have prevented it. Then say which of those three a spacecraft engineer would build into the rules.
