After President Vladimir Putin sent troops to Ukraine last year, the European Space Agency (ESA) said it would not cooperate with Moscow on the upcoming Luna-25 launch as well as future 26 and 27 missions.
Despite the pullout, Moscow said at the time it would go ahead with its lunar plans and replace ESA equipment with Russian-made scientific instruments.
Speaking at the Vostochny cosmodrome last year, Putin said the Soviet Union put the first man into space in 1961 despite "total" sanctions. He insisted Moscow would develop its lunar programme despite current Western sanctions.
"We are guided by the ambition of our ancestors to move forward, despite any difficulties and any attempts to prevent us in this movement from the outside," Putin said at the time.
