The Magellan Project 6.5-meter telescope is a collaboration of the Carnegie Institution of Washington and the University of Arizona. The telescope will be located on Cerro Manqui, at the Las Campanas Observatory, Chile. A design goal for the Magellan Project is to develop a telescope and enclosure system with a 1 degree(s) centigrade per hour time constant. The primary mirror is a University of Arizona borosilicate spincast honeycomb design. The enclosure is an octagonal shaped spaceframe structure with an insulated panel covering. The telescope fabrication is by L & F Industries. This paper will concentrate on thermal control of the telescope environment and the telescope thermal control interface to the enclosure.
