Scientific satellites are specialized spacecraft designed to collect data about Earth and its atmosphere, as well as other celestial bodies. They are equipped with various instruments that can measure temperature, humidity, and radiation, among other factors. This information helps scientists understand climate change, weather patterns, and natural disasters, contributing to advancements in fields like meteorology and environmental science. These satellites orbit the Earth or other planets and can be used for a variety of purposes, including remote sensing, astronomy, and space exploration. Notable examples include the Hubble Space Telescope, which studies distant galaxies, and the Landsat satellites, which monitor land use and environmental changes on Earth.
