(U) The Millstone Haystack radars support the imaging and cataloging of satellites and space debris. The radars are located at the Haystack Observatory in Tyngsboro MA.
(U) The Millstone Haystack complex consists of two radars that cannot be operated simultaneously sharing common hardware and power sources. The two radars are the Haystack Long Range Imaging Radar (LRIR) and the Haystack Auxiliary Radar (HAX). These radars support missions for USSPACECOM, the National Science Foundation, and for NASA. Their primary function is for deep space imaging of foreign and domestic satellites and orbital debris. They image every new foreign space launch in near earth, and image domestic satellites in trouble.
(U) The Haystack Auxiliary Radar is a K-band which has similar capabilities to the Haystack Long Range Imaging Radar but is not quite as sensitive. HAX, which was built by NASA, receives tasking exclusively from USSPACECOM/J2FS. It provides NASA with 800 hours per year of sample debris data.
(U) Loss of this capability would have a significant impact on the Space Surveillance Network (SNN).
