Watch ESA astronaut Matthias Maurer exchange a sample in the Materials Science Laboratory (MSL) on the International Space Station.

The sample is for an experiment called MICAST that aims to deepen our understanding of the physical principles that govern solidification processes in metal alloys. This knowledge could help improve casting processes on Earth, leading to the development of new lightweight, high-performance materials for future spacecraft and innovation.

Matthias is spending approximately six months aboard the Space Station for his ESA mission Cosmic Kiss. During this time, he will support around 36 European and many more international experiments in orbit.

Every process that occurs on Earth is subject to Earth’s gravitational pull. Studying these same processes in the weightless environment of the International Space Station allows researchers to better understand the impact gravity has. We can then use this knowledge to develop and enhance manufacturing processes, medical treatments, materials and more.
