Mission lesson
From launcher to first contact.
Stage 1 of 7
Mission
Who you are, what you are finding out, and what success looks like.
Showing stage 1 of 7: Mission
Mission
The moment a CubeSat leaves the launcher it is tumbling, cold and silent. Before it can do anything useful it has to stop spinning, find the Sun to charge, turn its antenna towards Earth and get a message through. Your team will run that sequence and work out which step is holding the whole mission back.
Every step scored something. So which one is actually stopping the mission?
- Your role
- Early-orbit operations engineer
- Objective
- Inspect a bounded deployment sequence and decide which step prevents a safe first-contact attempt.
- Success looks like
- Run the sequence, select the decisive state evidence, make an operations decision, and identify a limit of the software run.
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 how far the weakest step falls below the rest of the sequence, and demonstrate this by reporting that gap against named steps.
- 02By the end of this mission, the learner will be able to model why the overall score is a poor guide to whether the mission completes, and demonstrate this by explaining the role of the limiting step.
- 03By the end of this mission, the learner will be able to test whether this deployment meets a stated completion requirement, and demonstrate this by comparing the outcome against that requirement.
Preparation
Before we start
A quick check of what you already know. There is no score.
The idea behind the mission
The mission is a chain of steps. Every one has to work, so the mission is only as good as its weakest step.
A chain of steps, not a score
Stop tumbling. Find the Sun. Charge up. Point the antenna. Get a message through. Miss any one of those and the rest does not matter, however well it went. Engineers look for the step that limits the mission, not the average across all of them.
Predict before you run
Before you run anything: which step do you think will go worst - stopping the spin, finding the Sun, charging, pointing the antenna, or making contact? Say why.
Which step do you think will go worst, 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 deployment
- Write your prediction first.
- Read every step, not just the total.
- These are modelled mission results. No spacecraft was deployed and no contact was really made.
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 deployment. Every step is scored as the spacecraft works through the sequence.

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
Look for the lowest bar, not the average. That is the step deciding whether the mission works.
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 event was the strongest evidence for your decision, and what would still need confirmation before a real contact attempt?
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 weakest link
Think of a morning routine with five steps that all have to happen before you leave the house. Write them down, then mark the one that most often makes you late. Write one sentence on why fixing a different step would not help.
