What is planetary remote sensing?

Planetary remote sensing is the science of acquiring information about planets and other celestial bodies without making physical contact with them. This is typically done using satellites, spacecraft, and telescopes equipped with sensors that collect data in various wavelengths, such as visible, infrared, and radar. Scientists use this data to study surface compositions, atmospheres, climates, and geological processes on planets, moons, and asteroids. Planetary remote sensing plays a crucial role in space exploration, helping us understand the history and potential habitability of other worlds.
