Meetings
20 February 2025, Thursday
- Topál Dániel: Rippling sky, changing ice: the accelerated changes of Antarctic sea ice
Antarctic sea ice influences the response of the global climate system to anthropogenic climate change, for example by modifying the surface albedo and ocean circulation.

24 April 2025, Thursday
- Tasnádi Péter: Lightning, thunderclouds and climate (change)
24 September 2025, Wednesday
- Kereszturi Ákos: Supporting space probes with planetological research
A short overview of the probe-related research recently or currently under way at the CSFK Astronomical Institute: landing-site selection on the Moon for an ice-drilling probe; supporting the detector of asteroid-analysing space probes with artificially weathered meteorites; preparing the drilling of the ExoMars rover by studying terrestrial analogue sites; and getting to know targets for the GPR instrument of a future Martian drone.
22 October 2025, Wednesday
- Kordos László: Landmarks in the uncertain terrain of human evolution
- Farewell to our dear home, the Mathematics Museum.
19 November 2025, Wednesday
- Greeting Professor Kubovics Imre on his 100th birthday.
Main events
- Magyarok a Marson [Hungarians on Mars] robot competition, organised by Óbuda University and the University of Miskolc. Organisers: Vizi Pál and Sipos Tamás.
Relations with other organisations
Related organisations and programmes: NASA, ESA, the HUNOR programme, MANT.
- NASA lunar rocks, on loan from the Johnson Space Center Astromaterials Group. Occasional demonstration talks on the NASA lunar rocks; the loan began with a loan agreement signed in the autumn of 1993.
- Design and construction of the Hungarian experiments in the HUNOR programme. Vincze Miklós and Vizi Pál: flow experiments within the DIROS programme.
- Polgári Márta and co-workers: international manganese-ore research.
- Kereszturi Ákos: Mars research in international cooperation.
- Selmeci Áron: evaluation of part of the scientific, technology- and product-development experiment proposals of the HUNOR programme (after the last submission round), from the point of view of the safety of carrying out the experiments on the ISS and of the commercial exploitation of the results.
