MARS QUESTION AND EVIDENCE NOTES A reading aid from Yenra: https://yenra.com/picture-of-mars-exploration/ Prepared October 13, 2026. Use one sheet for one actual mission result. Source title and URL: _____________________________________________ Mission / instrument: _____________________________________________ Observation identifier: ___________________________________________ Observation date: _____________ Report publication date: ___________ 1. QUESTION What question is the investigation trying to answer? __________________________________________________________________ 2. MEASUREMENT Describe what the instrument recorded, before interpreting it. Include scale, wavelength, location or measurement units as relevant. __________________________________________________________________ 3. INTERPRETATION What physical process or history does the research team propose? __________________________________________________________________ 4. UNCERTAINTY What alternative explanation or missing information matters most? __________________________________________________________________ 5. NEXT TEST What observation could help distinguish the explanations? __________________________________________________________________ 6. FOLLOW-UP Study or data-product link: ________________________________________ What later evidence changes your notes? ____________________________ Worked hypothetical example (not an actual mission result): Question: Did a crater once contain a lake? Measurement: A channel ends in a fan-shaped deposit inside the crater. Interpretation: Water may have carried sediment into standing water. Uncertainty: Shape alone leaves the formation process and timing open. Next test: Compare layer structure, minerals and regional elevations. Keep a habitability interpretation separate from a claim of life. Keep acquisition dates separate from publication dates.
