Dale;
Being somewhat of a space and a science fiction buff I once looked up the two previous missions to the outer solar system prior to the Voyager probes, Pioneer 10 and 11. Both Pioneer's 10 and 11 were actually built by TRW, which surprised me at the time since I associated TRW with the manufacture of auto parts. In any event TRW was still in business up until 2006 when the auto parts division was sold off to Blackstone, and I think the aerospace division went to Lockheed-Martin (may have the wrong company), Blackstone has since sold the auto parts division to ZF.
Is that Freed the same Freed pf Freed-Eisemann fame?
Regards
Arran
