Agnirva Space Premier League - Expedition #32200: How Miniature Satellites Help Us Understand the Drag of Space

When we think of satellites orbiting Earth, we imagine them floating effortlessly in space. But in low Earth orbit, they’re actually plowing through a very thin atmosphere. The drag caused by this atmosphere affects satellite performance and longevity. The Satellite for Orbital Aerodynamics Research (SOAR) experiment, led by Dr. Peter Roberts from The University of Manchester, explores exactly how this drag works in microgravity.

Launched during Expedition 65, SOAR involves a CubeSat—a tiny satellite equipped with sensors to measure the effects of atmospheric drag. It helps scientists understand how different materials, shapes, and orientations affect how much a satellite slows down over time.

This knowledge is essential for optimizing satellite design, especially for missions involving long-term orbits. It can also help reduce space debris by improving deorbiting strategies. The experiment's international collaboration includes institutions in the UK, Denmark, and Spain, highlighting how global cooperation pushes the boundaries of space science.

By studying these aerodynamic effects in the unique environment of space, scientists can create more efficient, longer-lasting satellites—paving the way for more sustainable and effective use of space.
