Reconnaissance satellites are specialized spacecraft designed to gather information about the Earth's surface and atmosphere. They are equipped with advanced sensors and cameras that capture high-resolution images and data, which can be used for various purposes, including military intelligence, environmental monitoring, and disaster response. These satellites orbit the Earth at different altitudes, allowing them to cover large areas and provide real-time information. The data collected can help governments and organizations make informed decisions regarding national security, resource management, and urban planning, making reconnaissance satellites essential tools in modern technology.
