Agnirva Space Premier League - Expedition #30826: Smart Optical Fibers to Detect Radiation in Space

Radiation in space is invisible but potentially harmful to astronauts. To monitor exposure, scientists developed a cutting-edge technology called SOFPADS – Smart Optical Fibers for Passive Dosimetry in Space. Led by Dr. Noramaliza Noor and a consortium of Malaysian universities, this experiment flew on Expeditions 59/60 and 61/62.

These special optical fibers change their properties in response to radiation. The SOFPADS experiment tested their ability to measure space radiation levels passively – without power – and accurately. Optical fibers are light, flexible, and immune to electromagnetic interference, making them ideal for long-duration missions.

In orbit, the fibers were exposed to ambient space radiation. When analyzed post-flight, the team measured the changes to determine the total dose received. This technology could be used not only for space travel but also in medical imaging, nuclear facilities, and high-radiation environments on Earth.

This work demonstrates how innovative, collaborative research can produce practical tools for human space exploration.
