Agnirva Space Premier League - Expedition #31736: Scanning Earth from Space: Testing Miniature Radar on the ISS

Synthetic Aperture Radar (SAR) is a powerful imaging technology that can see through clouds, darkness, and even foliage. But what happens when you shrink it down and launch it to space?

That’s the goal of the Napor-miniRSA experiment, a series of missions led by ROSCOSMOS to test a miniature SAR system aboard the ISS. This tiny yet powerful radar tool can map Earth’s surface with incredible detail.

Deployed over several ISS expeditions (37 through 44), the miniSAR unit aimed to collect data from orbit while demonstrating how smaller radar systems could function effectively in space. These miniature systems offer the same capabilities as their larger counterparts but with much lower weight and energy requirements.

Applications range from natural disaster monitoring and environmental mapping to national defense. Having this technology tested on the ISS ensures it’s reliable, compact, and ready for broader use in future Earth observation missions.
