The United States and Russia will have set up habitats on Mars to reasearch ruins of an alien civilization



William H. Keith, Jr. : Author
"The United States and Russia have set up habitats on Mars, and are researching ruins of an alien civilization near the Face on Mars. The facilities and research are being shared with UN observers. When the UN sends troops up to Mars, the US sends the Marine Mars Expeditionary Force, a 30-man weapons platoon, to protect American civilians and interests on Mars."
