- ISRO reported that cosmic dust hits Earth’s atmosphere every 16 minutes.
- This was detected using the Dust Experiment DEX, which is India’s first indigenous cosmic dust detector.
- DEX was launched on January 1, 2024, on the X-ray Polarimeter Satellite XPoSat mission.
- The particles detected are Interplanetary Dust Particles that mainly come from comets and asteroids.
- These particles form a thin meteor layer in Earth’s atmosphere.
