Nothing new under the sun

TK is currently buried in the EUMETSAT programme. We might like to think that it all our Quasi-Optical work is new.... but a trip to the Smithsonian Air and Space Museum near Dullas airport  (Time to kill before a flight) .... presented the following Engineering Model of a 1960 Tiros weather satellite. Looks well made, with lightened mirror supports and a pair of corrugated feeds.
