The European Space Agency is an international organization that promotes cooperation in space research and product development. Founded in 1975, the agency has 22 member states and three associate members. Its headquarters are in Paris, France. The ESA's main objectives are to promote space exploration and utilization for the benefit of all humanity, to provide a space infrastructure for European industry, and to foster scientific and technological excellence. One of the ways the agency achieves these goals is through product development. The ESA encourages innovation by supporting the development of new products and technologies. In addition, the agency develops its own products and technologies for use in space exploration and other applications. The ESA's product development efforts have led to numerous innovations, including the first reusable spacecraft, the first artificial satellite of Mars, and the first droid used in space.
