Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the related topics?Geospatial intelligence, atmospheric science, photogrammetry, satellite remote sensing
2. Why do we need high-definition cameras in space?They help scientists see changes on Earth, like forests disappearing or ice melting, so we can protect the planet.
3. How do these cameras capture colors we can't see?They use multispectral and hyperspectral sensors that can detect light beyond the visible range, such as near‑infrared, to study plants and water.

Multispectral Imaging: Capturing image data at several discrete spectral bands, offering more information than visible light alone.
Hyperspectral Imaging: Capturing image data across hundreds of narrow, contiguous spectral bands for detailed material identification.
Spatial Resolution: The level of detail in a satellite image, indicating the smallest object that can be distinguished on the ground.
