Mars takes centre stage in the public STEM lecture series at the BTU

Entitled “Green-blue sunsets and other Mars rover stories”, the latest lecture in the public series “MINT on Wednesdays” will take place on 24 June 2026 at 5.30 pm on the main campus of BTU Cottbus-Senftenberg. The speaker is Prof. Dr Franz Renz from the Institute of Coordination Chemistry at Leibniz University Hannover.

Anyone interested is invited to attend in Teaching Block 1A (Lecture Theatre 1) at Konrad-Zuse-Straße 1. Admission is free. No registration is required.

About the lecture

Mars appears red and lifeless. Was Mars once a blue planet like Earth? If so, why is it no longer so? What happened? What does this mean for the future of Earth?
NASA’s Mars Exploration Rover missions, Spirit and Opportunity, operated on Mars for 15 years. One component of these missions is the miniaturised Mössbauer spectrometer (MIMOS). MIMOS detects only the element iron, but does so with great precision. This enables insights into the history of Mars.

Research and development of MIMOS is currently taking place at the Institute of Coordination Chemistry at Leibniz University Hannover, where Prof. Franz Renz – the officer responsible for this organised lecture – is based. MIMOS and various terrestrial and
extraterrestrial samples will be on display at the event, including a fragment of a Martian meteorite.

The public lecture series ‘MINT on Wednesday’ is organised by the MINT faculty – Mathematics, Computer Science, Physics, Electrical Engineering and Information Technology – at the Brandenburg University of Technology Cottbus-Senftenberg (BTU). It is aimed at members of the public interested in scientific topics, in particular pupils in the upper years of secondary school.
