The Thirteenth International Symposium on Space Terahertz Technology was held on the campus of Harvard University, Cambridge, Massachusetts, on March 26 – 28, 2002. The Symposium was attended by about 130 scientists and engineers, from all over the world. The Symposium was organized into 10 oral sessions and an interactive forum for poster presentation. In all, 70 papers, distributed into the following broad categories, were presented:

Hot Electron Bolometers	16
SIS Mixers	14
Local Oscillator Technology	14
Optics	9
Equipment and Components	6
Sub-millimeter Systems	6
Direct Detectors	5

A proceedings of the Symposium has been published. Included in these proceedings are 64 of the papers presented at the symposium and the 6 missing papers are represented by the accepted abstracts. Finally, we have also included one paper from the Twelfth Symposium, on request from last year's editor.

               Content of the Proceedings

The Symposium was made possible largely through the effort of the staff members of the Submillimeter Receiver Laboratory of the Harvard-Smithsonian Center for Astrophysics (CfA). We thank Joanne Reynolds who was key in all organizational aspects of the symposium, and in preparing and editing the proceedings. We also thank Professor Irwin Shapiro, Director of the CfA, for supporting the symposium, and Dr. Venkatesh Narayanamurti, Dean of Engineering and Applied Sciences, for his support through the use of the Robert and Naida Lessin Forum. Finally, we would like to thank the session chairs, presenters, and participants for making this Thirteenth International Symposium on Space Terahertz Technology, a success.
