In September 1996, the TSS traveled from California to Green Bank, West Virginia. After a six month stay at the largest radio telescope in the southern hemisphere, the TSS came back to the SETI Institute for more upgrades. The improved TSS was up and running at the Parkes Observatory in 1995. Based on the experience of the initial observations at Arecibo, Phoenix engineers doubled the number of channels and added a follow-up detection system. Congress cancelled the HRMS, Project Phoenix was born, and Arecibo was closed for several years for major upgrades.ĭuring those six years, Project Phoenix raised funds to continue and improve upon the Targeted Search portion of NASA's HRMS. In 1992, when the SETI Institute was last observing in Puerto Rico as part of the HRMS, the TSS had less than half its current capability.

In 1998, the ground-breaking detection setup that had been used for both the targeted components of the HRMS and Project Phoenix, a combination of hardware and software known as the Targeted Search System (TSS), returned to Arecibo after an eventful six years. The Arecibo Radio Telescope played a significant role in the both the NASA SETI program (eventually re-christianed HRMS) and later in Project Phoenix.
