The International Lunar Research Station (ILRS) (Chinese: 国际月球科研站) is a planned lunar base currently being led by Roscosmos and the China National Space Administration (CNSA). The ILRS will serve as a comprehensive scientific experiment base built on the lunar surface or in lunar orbit that can carry out multi-disciplinary and multi-objective scientific research activities including exploration and utilization, lunar-based observation, basic scientific experiment and technical verification, and long-term autonomous operation. Statements from Roscosmos and CNSA underline that the project will be "open to all interested countries and international partners."[7][8][9][10]


On 9 March 2021, China and Russia signed a “Memorandum of Understanding between the Government of the People’s Republic of China and the Government of the Russian Federation Regarding Cooperation for the Construction of the International Lunar Research Station.”[11] On 16 June 2021, Roscosmos and the China National Space Administration (CNSA) held a joint session in St. Petersburg on the auspices of the Global Space Exploration Conference (GLEX 2021), dedicated to the presentation of the Roadmap for the creation of the International Lunar Research Station (ILRS). The session was attended by Sergei Saveliev, the Deputy Director General of Roscosmos for International Cooperation and Wu Yanhua, the Vice Administrator of CNSA (remotely).

Roscosmos and CNSA representatives held consultations on a draft declaration in September 2021, together with experts from Germany, France, Italy, the Netherlands, Malaysia, Thailand and the UN Office for Outer Space Affairs. The talks took place behind closed doors.[12]

In June 2023, two more countries joined the International Lunar Research Station project, the United Arab Emirates and Pakistan, as well as the Asia-Pacific Space Cooperation Organization (APSCO). Malaysia may join in the future.

In July 2023, China's Deep Space Exploration Laboratory announced the signing of a memorandum of understanding with Swiss company Nano-SPACE for Cooperation on the International Lunar Research Station project.[13] On the same day, a letter of intent was also signed with the Hawaii-based, non-profit International Lunar Observatory Association (ILOA Hawai'i) (which already participated in the Chang'e-3 lander mission) for cooperation on the ILRS initiative, despite earlier restrictions by U.S. Congress limiting American collaboration with the China National Space Administration.[citation needed] ILRS's lab director Wu Weiren also led in-depth talks with officials from France's Thales Group, which considers the possibility for future cooperation with the Chinese space agency.[14]

On July 17, 2023, Venezuela formally joined the ILRS initiative, with its Bolivarian Agency for Space Activities signing an agreement with China's CNSA which, among other things, provided China access to Venezuelan ground stations in support of ILRS missions.[15]

On September 1, 2023, a Memorandum of Understanding was signed between Humbulani Mudau, CEO of SANSA (the South African National Space Agency), and Chen Xiaodong, Chinese Ambassador to South Africa, acting on behalf of CNSA. The agreement will reportedly see CNSA and SANSA carry out extensive cooperation in the demonstration, implementation, operation and application of the ILRS, as well as training and other areas.[16]

On October 3, 2023, an agreement was signed between China's CNSA and Azerbaijan's Azercosmos regarding the latter's entry into the International Lunar Research Station Program. Azercosmos director Samaddin Asadov signed the agreement at the 74th International Astronautical Conference, held in Baku.[3]

Definition and composition

ILRS is a complex experimental research facility to be constructed with a possible attraction of partners on the surface and/or in the orbit of the Moon designed for multi-discipline and multi-purpose scientific research activities, including exploration and use of the Moon, Moon-based observation, fundamental research experiments, and technology verification with the capability of long-term uncrewed operation with the prospect of subsequent human presence.[17]

Scientific objectives



Phase 1: Reconnaissance (2021–2025)


Planned Missions

Most missions that are planned in the reconnaissance era weren't specifically planned for the ILRS, with some being planned far back into the 90's.[18] However, their reconnaissance can still prove useful to the overall mission.

Chang'e 4

Chang'e 4 was a soft landing on the far side of the Moon, Launched on 7 December 2018, entering lunar orbit on 12 December as a part of China's own Chinese Lunar Exploration Program. While not specifically made for the Research Station, as it was a backup module for its predecessor, Chang'e 3.[19] However, it has still helped with Reconnaissance for the mission as a whole, a theme for most reconnaissance missions for the Research Station.

Luna 25

Luna 25 was sent to the Moon by Roscosmos to deliver 30 kg of scientific payloads and instruments to the surface of the Moon. It was not planned specifically for the Research Station, with planning going back all the way to 90's. However, this craft has crashed on the moon due to an incorrect orbit calculation.[20][21]

On 25 August 2023, Roscosmos Director Yury Borisov, during a meeting with representatives of NPO Lavochkin involved in the development of the mission, stated that consideration was being given to recreating the Luna 25 mission with a possible launch for the second attempt slated to occur in 2025 or 2026.[22]

Luna 26

Luna 26 is a planned lunar polar orbiter. Along with the scientific payload that it carries, it would allow for a telecom array for landed Russian assets, and Earth. The mission was announced in November 2022, and it has a launch plan for 2027. It will study the lunar surface and do some reconnaissance for the future Luna 27.
