Saarland University team to study metallic‑glass alloys on ISS with levitating droplets

Researchers from Saarland University, led by materials scientist Ralf Busch, are preparing for their first science‑in‑space mission. Beginning 31 August, the team will conduct a one‑week remote investigation of metallic‑glass alloys aboard the International Space Station (ISS). The experiments will focus on the behavior of hot, levitating droplets of the alloys, allowing scientists to observe their properties without the influence of Earth’s gravity.

The project is a collaboration with the European Space Agency (ESA) and the German Aerospace Center (DLR). By using the ISS’s microgravity environment, the researchers aim to gain new insights into the fundamental characteristics of metallic glasses, which could inform the development of advanced materials for aerospace, automotive, and industrial applications. The data collected will be transmitted to the team on the ground for real‑time analysis and subsequent publication.

If the mission proceeds as planned, the findings will represent a significant step forward in space‑based materials science. The results are expected to contribute to a deeper understanding of how metallic glasses behave under extreme thermal and microgravity conditions, potentially leading to the design of stronger, more resilient materials for future technologies.
