We had two Soylentils write in about President Trump's posting on twitter an image of a failed Iranian attempt to launch a satellite. Analysts were stunned at the resolution and clarity of the picture since it appears to have been taken from a US Spy satellite. A commercial-quality image of the same site is shown in the article from Ars Technica and the difference is striking.

President Trump Tweets Picture of Sensitive Satellite Photo of Iranian Launch Site

President Trump tweets picture of sensitive satellite photo of Iranian launch site

President Donald Trump posted a photo today via Twitter of Iran's Imam Khomeini Space Center in northern Iran, showing the damage done to the facility by the explosion of what appears to have been a Safir rocket during launch. The rocket was apparently being used in the attempted launch of Iran's Nahid-1 satellite.

Commercial satellite imagery from Planet Labs made available this morning showed a plume of smoke rising from the space center's launch pad. But the photo posted by President Trump was a much higher-resolution, black and white photo—a resolution that suggested it came from a National Reconnaissance Office satellite.

Amateurs Identify U.S. Spy Satellite Behind President Trump's Tweet

The image almost certainly came from a satellite known as USA 224, according to Marco Langbroek, a satellite-tracker based in the Netherlands. The satellite was launched by the National Reconnaissance Office in 2011. Almost everything about it remains highly classified, but Langbroek says that based on its size and orbit, most observers believe USA 224 is one of America's multibillion-dollar KH-11 reconnaissance satellites.

[...] The image tweeted by Trump on Friday, showing the aftermath of an accident at Iran's Imam Khomeini Space Center, was so detailed that some experts doubted whether it really could have come from a satellite high above the planet.

[...] a small community of amateur satellite trackers was far more interested in the picture than the words. These individuals use backyard telescopes to watch satellites whizzing across the sky, and they know where most of them are — even classified ones like USA 224. "They're super bright in the sky and are easy to find," says Michael Thompson, a graduate student in astrodynamics at Purdue University who spots satellites in his spare time. Once a satellite is seen, it's relatively easy to work out exactly where it will be at any point in the future. "Using math to calculate an orbit is really easy," he says.

Thompson was one of the first to use an amateur-curated database of known satellites to point the finger at USA 224. He showed that it flew over the Iranian space center shortly after the accident.

Langbroek went further still. He was able to reconstruct the picture taken by USA 224 by matching the obliqueness of the circular launch pad in the image tweeted by Trump. His calculation showed that the photo was taken from the vantage of USA 224. Langbroek and another online researcher, Christiaan Triebert, also used shadows cast by towers around the launch pad as sun dials—allowing them to verify the time at which the photo was taken.

Both techniques suggest the pictures were snapped by USA 224, which flew near the site at 2:14 p.m. local time. "The match was perfect, basically," Langbroek says.

    Why does everybody assume it's way out in space? A high altitude drone or balloon can be used and it wouldn't be around long enough for you to know what they had inside of it. It can apply all the same tricks a sat can as well but it is just closer and money is basically unlimited; they could launch non-stop if they wanted... It's not like we didn't used to constantly fly U2 spy planes before spy sats.

    This photo is likely a sat; but to count the hairs on your head they probably have a drone... if there is actually a NEED for that kind of resolution... which they probably have dreamed up.

    True, it could have been something else (and would have been even more silly for the President to then show that they had drones or spy aircraft over 100 miles inland). But it's no longer assumed, others have already done the legwork to prove it matches up perfectly with USA-224 having taken it. [wired.com] That's why.
