Space Agency

A space agency is a governmental or intergovernmental organization responsible for the development and implementation of space programs and activities. These agencies are involved in designing, building, launching, and operating spacecraft for various purposes such as scientific research, communication, navigation, and national security. Space agencies also conduct space exploration missions to study celestial bodies and phenomena, and to search for signs of life beyond Earth. They collaborate with other space agencies and private companies to share resources, knowledge, and expertise in order to achieve common goals and advance space technology. Some of the most well-known space agencies include NASA (USA), ESA (Europe), Roscosmos (Russia), JAXA (Japan), and CNSA (China).
