CubeSTEM Mission Twin — V3.4 Architecture
Mission Challenge Architecture
CubeSTEM Mission Twin combines the existing CubeSat digital twin with space robotics mission challenges — rover operations, telemetry divergence, fault injection, and evidence-based diagnosis. Students operate CubeSat and space-robot assets through realistic mission scenarios that connect to all eight learning tracks.
Architecture Layer
What This Phase Delivers
V3.4 Mission Challenge Architecture establishes the data model, route structure, and product direction for mission-based challenges. It does not implement the full rover simulator — that is the target for the next phase (v3.4-space-rover-twin-v0).

Product Positioning
CubeSTEM Mission Twin positions space robotics as a natural extension of CubeSat STEM education — not a generic robotics kit. This avoids the crowded general robotics market and creates a distinctive offering for schools, colleges, makerspaces, NAVTTC programs, CSR initiatives, grant/tender applications, and space outreach.
- Software-first — full mission experience runs in the browser with no hardware required
- Hardware-ready later — architecture supports future integration with third-party robot kits
- Space mission framing — rover operations are contextualized as lunar/planetary missions, not tabletop robots
- Teaching-grade — designed for learning and evidence capture, not certified engineering analysis
Mission Challenges
Five mission concepts spanning school to university level. Each mission connects CubeSat and space robotics assets with learning tracks, fault injection, and evidence-based diagnosis.
NewTelemetry Divergence Engine v0 — expected vs observed telemetry comparison now available in Lunar Rover Rescue and CubeSat–Rover Relay.
Lunar Rover Rescue Mission
Interactive PrototypeA CubeSat relay satellite provides a limited communication window over a lunar surface site. Students must command a virtual rover to navigate to a damaged solar panel, inspect the damage, manage battery constraints under communication delay, diagnose faults from telemetry, and generate an evidence report before the pass window closes.

Connected Tracks
Learning Objectives
- Operate a rover under communication delay constraints
- Manage a limited energy budget during a timed mission
- Diagnose faults from telemetry divergence (expected vs observed)
- Generate structured evidence from mission data
- Understand CubeSat relay communication windows
Student Challenge
Can you rescue the rover and complete the inspection before the communication window closes? You must manage battery, handle delay, and diagnose faults using only the telemetry you receive.
Teacher Use
Use as a capstone challenge after Tracks 0–6. Students apply knowledge from all tracks in a realistic mission scenario. The teacher runbook provides timing presets, discussion prompts, and rubric templates for classroom or workshop delivery.
Evidence Outputs
- Fault Diagnosis Report — Document observed vs expected telemetry and identify the root cause.
- Mission Timeline — Record command sequence, timing decisions, and communication windows used.
- Energy Budget Analysis — Track power consumption against battery capacity over the mission.
Future Simulator Need
Requires a 2D rover simulator with simple grid movement, battery model, communication delay, and telemetry stream. Target for v3.4-space-rover-twin-v0.
CubeSat–Rover Relay Mission
Interactive PrototypeA CubeSat in low orbit provides intermittent communication passes over a surface site. Students plan command uploads and data downloads around the satellite pass schedule, managing the handoff between ground station, CubeSat relay, and rover.

Connected Tracks
Learning Objectives
- Plan communication schedules around orbital pass windows
- Manage data uplink/downlink budgets
- Handle relay handoff between ground station and rover
Student Challenge
Can you deliver all commands and retrieve all science data within the available pass windows?
Teacher Use
Use after Tracks 1 and 4 to reinforce communication and orbit concepts in a multi-asset mission context.
Evidence Outputs
- Communication Plan — Document uplink/downlink schedule aligned to satellite passes.
- Data Budget Report — Track data volume vs available bandwidth per pass.
Future Simulator Need
Requires pass schedule simulation and data budget tracker. Planned for a phase after v3.4-space-rover-twin-v0.
Damaged Solar Panel Inspection
PlannedA rover with a camera approaches a damaged solar panel on a surface asset. Students guide the rover to capture inspection images, assess damage severity, and generate an evidence report with recommendations.

Connected Tracks
Learning Objectives
- Conduct a systematic visual inspection of space hardware
- Assess damage severity from limited observational data
- Generate structured evidence reports
Student Challenge
Can you inspect the damaged panel, assess the damage, and write a clear report before your rover runs out of battery?
Teacher Use
Use as an introductory mission challenge for younger students. Connects to Track 3 power concepts and Track 6 evidence skills.
Evidence Outputs
- Inspection Report — Document observations and damage assessment with supporting evidence.
- Recommendation Brief — Propose repair or replacement actions based on inspection data.
Future Simulator Need
Requires a simple grid-based rover with image capture simulation. Can share the rover framework from Lunar Rover Rescue.
Disaster Mapping Relay Challenge
ConceptA satellite and a ground-based robot collaborate on a disaster mapping mission. Students use satellite imagery to identify areas of interest, then command a surface robot to scout specific locations for flood risk, glacier movement, or structural damage.
