Mission question

How can the CubeSat reduce its tumble, recover power, point toward Earth and deliver its first packet without creating excessive overshoot, energy use or actuator stress?

Prediction before running

I predict that...State what you think will happen and why. Name the control style or policy you expect to work best.

Controlled experiment plan

Variables I will keep the sameKeep the mission seed fixed and avoid changing more than one intended variable.

Explain the spacecraft behavior

What changed in the motion?Use angle, angular rate, overshoot, settling or wheel evidence.What changed in power or communications?Use solar input, battery, link quality or packet evidence.What trade-off did you observe?Examples: faster response versus overshoot, stability versus energy, retries versus time.

Telemetry provenance

Classify at least five channels from your run. M1 software-only mode contains no measured hardware channels.

Channel	Provenance	Why?

Simulated: Physics or subsystem state produced by a model

Estimated: A sensor-style estimate derived from simulated truth

Commanded: A validated controller or mission command

Reference: A target or desired mission value

Derived: A calculated value such as pointing error or link quality

Conclusion and next test

My evidence supports / does not support my prediction because...The next experiment I would run is...Name one variable and one metric you would measure.
