How does dust on Earth compare to dust on Mars?

What you can answer

• Compare the mineral fingerprint of dust-source regions on both planets.
• Use Mars’ dust-storm behaviour to sharpen questions about Earth’s, and vice versa.

What you can NOT answer with these datasets alone

• Combine the pixels directly — different worlds, instruments and scales.
• Measure airborne dust composition — EMIT reads the surface source.

The cross-division bridge

Earth-anchored, reaching into Planetary Science. Both sides use the same physics — imaging spectroscopy. The Earth side is EMIT on the ISS, mapping the mineralogy of arid dust-source regions. The Planetary side is MRO CRISM, the visible-infrared spectrometer that mapped minerals across Mars. The shared technique lets each world’s dust science inform the other.
