On the 30th August 2019, the President of the United States tweeted an image of an Iranian spaceport, making note of the recent failed Safir launch at the site. The release of such an image prompted raised eyebrows, given the high resolution of the image, and that it appeared to be a smartphone photo taken of a classified intelligence document.
Inquisitive minds quickly leapt on the photo, seeking to determine the source of the image. While some speculated that it may have been taken from a surveillance aircraft or drone, analysis by the satellite tracking community disagreed.
A comparison of the actual image, top, and a simulation of what a shot from USA 224 would look like. Ignore the shadows, which are from an image taken at a different time of day. Note the very similar orientation of the features of the launchpad.
The angle of shadows in the image was used to determine the approximate time that the image was taken. Additionally, through careful comparison with existing satellite images from Google Maps, it was possible to infer the azimuth and elevation of the camera. Positions of military satellites aren’t made public, but amateur tracking networks had data placing satellite USA 224 at a similar azimuth and elevation around the time the image was taken.
With both the timing and positioning pointing to USA 224, evidence seems conclusive that this KH-11 satellite was responsible for taking the image. The last confirmed public le ..
