Earth Probes
Earth probes are unmanned spacecraft designed to study the Earth and its environment from space. They are equipped with various scientific instruments to collect data on the Earth's atmosphere, oceans, land, and climate. Earth probes are used to monitor weather patterns, track changes in the Earth's magnetic field, measure the thickness of polar ice caps, and study the effects of human activity on the environment. They are launched into orbit around the Earth and can operate for several years before their mission is complete. Some examples of Earth probes include the NASA's Terra, Aqua, and Aura satellites, as well as the European Space Agency's Sentinel-1 and Sentinel-2 missions.
