Satellite Imagery

Satellite imagery in open source intelligence (OSINT) is the use of commercial satellite photographs, and of fire detections from thermal satellites, to confirm, date or contradict accounts of what happened on the ground. Telegram channels such as Exilenova+ and Dnipro OSINT, projects such as Absolutely Reliable Source, and newsroom teams at Bellingcat and India Today do the work, using passes from providers such as Vantor, Planet Labs and Copernicus Sentinel-2. Its findings have corroborated strikes before any official comment and shown viral pictures to be months old.

NASA's fire detections give an early independent check that a strike on a Russian site landed, sometimes within hours. Successive passes then follow damage across repeated strikes on an oil hub, a drone base and a bridge, and later passes can confirm losses that earlier images could not. Roof damage seen from orbit still does not show whether a factory stopped working. Comparing passes over weeks or years records construction and movement, from a new Russian drone-launch base to depleted launcher stocks, and dry-dock imagery has exposed design features of a Chinese submarine. Imagery also dates pictures shared online and separates sites that were hit from sites that were not.

As of October 2026, imagery reviewed by open-source analysts showed every large floating-roof tank at a Transneft crude-blending hub near Samara damaged or destroyed after four strikes in nine days, and a Russian drone-launch site near Millerovo, an empty field on 1 September, with its first section close to completion.

Thermal fire detections

NASA's Fire Information for Resource Management System (FIRMS) publishes fire detections from thermal satellites, and open-source monitors use it as an independent check on strike reports. At the Tsymbulovo jet-drone base in Russia's Oryol region, FIRMS detected fire hotspots from around 1:33 a.m. on 3 October 2026, clustered over storage hangars, preparation workshops and launch pads, as first flagged by the Telegram channel Exilenova+. The following night FIRMS recorded a high-temperature fire signature across the perimeter of the Khanskaya airbase in Adygea during the attack.

The detections can run ahead of the official account. When drones hit the Sasta machine tool plant in Sasovo, in Russia's Ryazan region, overnight into 8 October 2026, FIRMS placed a blaze at the plant and the Yandex data centre on its site shortly after 2am, before any Russian official comment.

Damage across repeated strikes

Successive passes over one site let analysts follow damage from strike to strike. Absolutely Reliable Source tracked Transneft's crude-blending hub near Samara through strikes on 2, 7, 10 and 11 October 2026, and found every RVSPK-50000 floating-roof tank damaged or destroyed after the fourth. At Tsymbulovo, an image released by 10 October after a further strike showed fresh damage to fortified bunkers, a jet-drone launch pad and a storage area, in at least the third documented wave of strikes on the base since September.

Later passes can close gaps that earlier ones left open. The first imagery published after the Khanskaya strike showed damage but could not by itself confirm the loss of the Su-35 fighter and Su-34 fighter-bomber that Ukraine's Security Service (SBU) said its drones hit. By 6 October, imagery from the AviaVector monitoring community, analysed by Militarnyi, showed destruction on the taxiways where open-source analysts place the two aircraft. The Telegram channel Dnipro OSINT followed the Chonhar road bridge, one of only two land routes between Crimea and the occupied part of Kherson region, from a 26 September pass showing at least three large holes in the deck to a 30 September pass showing a span collapsed.

Imagery shows what a strike hit more readily than what it disabled. At the Azov Optical-Mechanical Plant, struck overnight into 26 September 2026, a workshop-by-workshop review by the OSINT community Absolutely Reliable named the foundry, mechanical processing, optics, assembly and electroplating shops as damaged. Yet roof and building damage visible from orbit did not establish whether production had stopped. Leaked supply documents reviewed by Defense News described the plant's role in far more detail than imagery could, including a navigation lidar and flight-automation block for the Kh-101 cruise missile.

Construction and military stocks

Comparing passes over weeks shows what is being built. Planet Labs imagery analysed by Absolutely Reliable Source showed a field near Millerovo in Rostov region still empty on 1 September 2026. By October 2026 the site's first section held eight launcher positions and 32 drone preparation positions, and a 12 October image showed drones being unloaded. The analysts believe it is meant for jet-powered Geran-5 drones and compare its layout to Tsymbulovo, while cautioning that those conclusions rest on imagery and their own assessment rather than direct confirmation. At Tsymbulovo itself, Ukrainska Pravda's imagery analysis counted 23 drone launchers in October 2026, with four more for jet-powered drones planned.

Counting vehicles over years can expose reassignments. An open-source researcher known as AS-22 found that the rare 51P6A S-400 launchers stored at the Kapustin Yar test range fell from about 30 in 2022 to 14 by 2025. SBU footage of its September 2026 operations appears to show the missing launchers reassigned to fire ballistic missiles at Ukraine, matching Ukrainian intelligence reports that Russia refits S-400 air-defence missiles as a ground-attack weapon, the RM-48U. Analysts tell a 51P6A apart by its Belarusian-made MZKT-7930 chassis and by its movement without the radar vehicles of an air-defence battery.

Satellite imagery also reaches naval programmes outside the war. Vantor imagery of a dry dock at the Bohai Shipyard in Huludao, analysed by Janes and The War Zone, confirmed a shrouded pumpjet propulsor and X-tail stern planes on China's next nuclear-powered attack submarine, widely called the Type 095, both firsts for a Chinese boat of that kind. Analysts had previously inferred the stern design from partial images of the submarine in the water.

Dating and correcting viral claims

Imagery is also the test for pictures and claims that spread online. Google Maps images of flattened Gaza neighbourhoods were shared widely as a fresh update, but a Google spokesperson told Bellingcat the imagery had been available since June 2026, and The Guardian reached the same June dating independently by comparing imagery of Al-Mawasi. Bellingcat then used newer Planet Labs and SkySat imagery to show destruction had advanced well beyond the viral pictures, with new damage in Rafah, a new Israeli military outpost in Bani Suheila and more structures destroyed in northern Gaza.

After US Defense Secretary Pete Hegseth shared an image of a tower collapsing at Iran's Chabahar port in July 2026, posts claimed India's investment there had been "reduced to rubble." India Today's OSINT team compared Vantor imagery from before and after the July strikes, plus Sentinel-2 passes into October 2026, and found no visible damage to the India-funded Shahid Beheshti terminal. The strike damage was concentrated at Chabahar's other terminal, Shahid Kalantari, about 2.5 kilometres north. The team cautioned that Sentinel-2, at about 10 metres per pixel, cannot rule out smaller damage until higher-resolution imagery of the terminal is available.
