Agnirva Space Premier League - Expedition #32368: How Space Helps Test the Shelf Life of Biodegradable Drug Systems

Biodegradable polymer drug delivery systems are revolutionizing the way we administer medicine. They break down naturally in the body, releasing medication gradually and reducing the need for repeated doses. But what happens when these systems are exposed to the extreme conditions of space? That’s what the Shelf Life of Biodegradable Polymer Drug Delivery Systems in Low Earth Orbit Conditions experiment set out to explore aboard the International Space Station (ISS).

The idea behind this experiment is simple but profound: understand how long these drug systems remain stable and effective when stored in space. Space is filled with challenges—radiation, microgravity, and fluctuating temperatures—that can degrade materials in ways Earth cannot. This research, led by Principal Investigator Jakub Wlodarczyk from the Centre of Polymer and Carbon Materials of the Polish Academy of Sciences, is critical for long-term space travel. Astronauts on extended missions, such as a journey to Mars, need medications that remain safe and effective for months, if not years.

In the experiment, various polymer-based drug delivery systems were stored on the ISS for a set duration during Expeditions 73 and 74. These systems were analyzed for changes in chemical structure, release rates, and effectiveness. The results will inform the development of next-generation drug systems that are not only biodegradable but also space-hardy. This can benefit not just astronauts but also improve similar medical technologies on Earth, particularly in remote or disaster-stricken areas.

With the backing of the European Space Agency (ESA), this experiment underscores Europe’s commitment to leading-edge medical and materials science research in space. As we prepare for deeper space exploration, this kind of research ensures the health and safety of space travelers—and potentially millions on Earth.
