Kairos is the history of the first design of architecture - in its most elevated sense - for a space project. Between 2008 and 2011, the Brazilian architect and urban planner Emanuel Dimas de Melo Pimenta designed a building to be permanently in orbit of planet Earth. Beyond an architectural design it also is a reflection on the human condition, on the possibility of the end of wars, of the leap of Humanity to the Universe and on a civilizational metamorphosis. But it also is a technical and technological questioning, and an artwork. With additional texts by the architects Carlos Zibel and Bruno Padovano, of the astrophysicist Amancio Friaca, and a poem of the hypermedia artist Artur Matuck - all from USP University of Sao Paulo, Emanuel Pimenta's book also tells the history of the design of space stations, from the 19th century to now, in a fabulous trip with the reader."
