[FPSPACE] Aviation Week...........COSMOS 2441

[John Locker]

Hi Jim

As pointed out on another list , the satellite image used by AW  turns out 
to be that of  the DK - 1

Mark says " The Resurs DK1, which is almost identical in appearance to the 
Persona configuration, was first displayed by the Russians at the 2003 Paris 
Air Show. "

If my images are correct , Persone is nothing like DK-1....


I will however concede that having re done the math , the satellite is 
probably nearer 7 -8 metres in length rather than 5.....I had overlooked the 
fact that my previous calculations took into account a 1:1.6 lens , which on 
this occassion I hadnt used.

It remains to be seen if we ever get the chance to compare the attached 
concept drawing to the the "real thing "  :O)

John
