Evidence engine v0 preview
This preview demonstrates local evidence artifact capture. It is not a submission system.
Capture
Evidence capture (local-only)
Capture what you did, what changed, what you observed, and how you explain it. This stays in your browser unless you copy/share it manually.
Selected inputs
- Mission objective: Measure urban heat islands after sunset.
- Payload idea: Thermal camera (low-resolution) with scheduled captures.
- Downlink plan: Store-and-forward; downlink during 2 contact windows per day.
Generated outputs
- Subsystem list: Power, communications, ADCS (pointing), onboard computer, structure.
- First trade-off noticed: More images → more data → longer downlink time and higher power use.

Evidence artifact (v1) Activity: What is a CubeSat Mission? Track: orientation Learner level: high_school Captured: 2026-05-16T07:38:33.839Z Mission brief: Design a beginner CubeSat mission concept by choosing a mission objective, a payload idea, and the key subsystems needed to make it work. Selected inputs: - Mission objective: Measure urban heat islands after sunset. - Payload idea: Thermal camera (low-resolution) with scheduled captures. - Downlink plan: Store-and-forward; downlink during 2 contact windows per day. Generated outputs: - Subsystem list: Power, communications, ADCS (pointing), onboard computer, structure. - First trade-off noticed: More images → more data → longer downlink time and higher power use. Checklist: - [x] I can state a one-sentence mission objective. - [ ] I can explain how the payload supports the objective. - [ ] I can name at least three supporting subsystems and why they matter. - [x] I included an honest boundary note about what this twin does not prove. Observations: I noticed that mission goals are not the same as payloads. The payload is a tool, but the objective is the outcome we want on Earth. Reflection: If we needed higher image resolution, we’d need more data capacity and probably more power. That could push us toward a larger satellite or fewer images per day. Assessment summary (local-only): - Completed: 2/4 - MCQ correct: 1/1 - Checklist: 2/4 - Note: Sample local-only practice summary (not a grade; not submitted). Model boundary note: Local-only teaching model. This evidence is not submitted anywhere and does not prove flight readiness or hardware performance. Policy reminder: - Local-only capture. Not submitted anywhere. Not a grade.
