## The human problem

Earth-observation satellites collect more imagery than they can always send down quickly, while many decisions benefit from identifying useful scenes earlier.

## The prior constraint

Raw imagery must often wait for bandwidth and ground processing before screening.

## AI’s actual role

The model performed inference onboard to identify flood and cloud features before full data return.

## The documented result

NASA reports demonstrations on two orbital platforms. Prithvi was trained on 13 years of Harmonized Landsat and Sentinel-2 data; the flight result is currently described in a preprint.

## Why it may matter

Onboard screening could help prioritize limited bandwidth, but a demonstration is not a deployed warning system.

## Limitations

The result is a preprint.

Two demonstrations do not establish broad satellite reliability.

Flood detection onboard does not equal an official flood alert.

## Unresolved questions

What accuracy and compute tradeoffs followed compression?

How did radiation and hardware constraints affect inference?

Which outputs were verified against ground truth?
