The International Lunar Research Station (ILRS) is a planned moon base to be built by Roscosmos (of Russia) and the China National Space Administration. The goal of the ILRS is for scientific experiments and other research. It would also focus on exploration of the moon. Russia and China have invited other countries and organizations to help with the project. They intend to start a long-term presence on the moon between 2036 and 2045. Prior to this many missions will be needed to explore and prepare for a base.
