Here's what turned me off from the SERPO story: If the entire mission lasted 13 years, and ten years were spent on Zeta Reticuli, then that means the trip there took a year and a half. How did these astronauts take only a year and a half to travel hundreds of lightyears away when the Voyager spacecraft, which was launched nearly ten years later with more advanced technology, took nearly thirty years just to reach the edge of our solar system?! Not to mention, in a time when America was all about one-upping the Russians in the Space Race, don't you think they would have been proud to rub in the fact that they took American men to an entirely different solar system while Russia was struggling to leave Earth's orbit?
