The modules that the major space agencies plan to erect on the Moon could incorporate an element contributed by the human colonizers themselves: the urea in their pee. European researchers have found that it could be used as a plasticizer in the concrete of the structures.
The 1,554 inhabitants of Fresnedillas de la Oliva (Spain) are making preparations to celebrate the 50th anniversary of the arrival on the Moon. It was in this small village where the expected Apollo XI landing signal was received through the antenna that NASA installed on their land. That changed the lives of its inhabitants, who now remember how they cooperated in that great step for mankind.
Scientists from the Polytechnic University of Catalonia and other international collaborators have proposed a system of mirrors, processed lunar soil and a heat engine to provide energy to vehicles and crew during the lunar night. This would preclude the need for batteries and nuclear power sources such as those used by the Chinese rover that recently landed on the moon.
