Appendix G. Acknowledgments

IRAC would not have been the successful instrument it was without the enthusiastic and capable contribution of many colleagues (see the lists of collaborators and laboratories below). Support for the IRAC instrument was provided by NASA through contract 960541 issued by JPL.


Principal Investigator

Dr. Giovanni Fazio (SAO, Harvard)

Dr. Gary J. Melnick, Deputy Principal Investigator (SAO, Harvard)

Dr. Joseph L. Hora, Project Scientist (SAO, Harvard)

Richard S. Taylor, Project Manager (SAO, Harvard)



The co-investigators played a central role in defining the technical characteristics of IRAC in order to carry out the science programs agreed upon by all of them. Lynne Deutsch, a co-investigator of IRAC, died on 2004 April 2, after a long illness. Lynne was a dear friend and a close colleague. The IRAC team deeply misses her presence.

Construction and ground calibration phase


People listed here include those that participated in the mechanical, optical, and cryo-mechanical studies that led to the definition of IRAC, as well as those who designed and built the on-board electronic subsystems, developed the on-board software and worked on the Ground Support Equipment. Others participated in the development of the extensive software systems and procedures later used for the in-flight calibration, system tests and uplink subsystems or in the Off-Line pipeline.
