Having already had a suspected failure earlier in the year, there is increasing evidence that Iran had a second launch failure of one of its Safir launch vehicles during an orbital attempt on or shortly after 22 September. The initial evidence was disclosed by Jane’s Defence Weekly as it cited various satellite imagery and intelligence data that Safir launch had blown up soon after lift-off. Since then other intelligence sources have confirmed the launch failure though Iran has not, as yet, admitted to the failure, nor has it admitted to the previous one in May. A discussion of the various pieces evidence is available on the nasaspaceflight forum here.
