Side-by-side maps of Ukraine’s eastern Donbas region—the frontline of the war—dated July 8 and July 12, show the number of active bombings by Russians before and after Ukraine ramped up attacks using the HIMARS precision rocket weapon system provided by Washington.

NASA’s Fire Information for Resource Management System or FIRMS was created to monitor large-scale fires.

The maps illustrate a sharp decrease in the number of fires detected by NASA satellites—an indicator that long-range strikes on Russian ammunition warehouses appear to be playing in Ukraine’s favor.

On July 9, Ukrainian presidential adviser and peace talks negotiator Mykhailo Podolyak named HIMARS as one of three weapons Ukraine needs to turn the tide of Putin’s war in Ukraine, as clashes intensified in the battle for the country’s eastern Donbas region

“Do we want a turning point in the war? 3 components… HIMARS for high-precision targeting rear bases, logistics,” he tweeted. “Heavy artillery on the frontline allows matching number parity. APC [armored personnel carriers] for “breakthrough fists”… More tools faster we’ll clean our land of the Russians.”
