Our activities and results

The space research activity of our group belongs to space physics among the main directions of the Space Research Scientific Council, and to astrophysics in the NASA database. We have four working groups, active in the following fields of research and education.

Lunar rocks, meteorites and the evolution of celestial bodies

In 2002 our space research group had important sets of cosmic material on loan: NASA’s petrographic thin-section and mounted-disc set of lunar rocks (7th international loan agreement with the NASA Johnson Space Center) and the collection of Antarctic meteorite thin sections of the Japanese National Institute of Polar Research (NIPR). This year we also supplemented them with a third sample group, thin sections of Hungarian meteorites, and a fourth, consisting of samples from the Earth’s crust and mantle. We wrote several summary papers on the study of cosmic materials. One group of them deals with the evolution of chondritic bodies (first stage: heating, with metamorphism in the texture of the chondritic rock; second stage: partial melting and migration of the melts); the other deals with the comparative study of NASA lunar rocks, NIPR Antarctic meteorite breccias and industrial materials (ceramics), which we present in the education section.

Geomorphology and planetology

In 2002 we studied the atmospheres of Solar System bodies and how the atmosphere interacts with the surfaces of those bodies. We continued our lecture series within the planetology course announced by the Department of Physical Geography of the ELTE Faculty of Science. Members of the group also took part individually, with several papers, in the LPI/NASA LPSC conference.

This year’s summary work on the atmospheres of planetary bodies was prepared for our atlas series presenting the Solar System. Its fourth volume is the Atlas of Planetary Atmospheres, which presents the atmospheres of the planets. We know most details about the atmosphere of the Earth and about the atmospheric circulation of Jupiter. Our volume outlines the main atmospheric and surface interactions and gives comparative tables of the layering and main state parameters of the atmospheres known so far. This volume of our atlas series on Solar System materials is also well suited for use in secondary and higher education.

We continued our work on the topic initiated by Horváth András, the research of the Martian dark spots (DDS). Using the new MGS images, we were able to subject the sequence of transformations of the DDS to a longer time-series analysis, and we also examined the seasonal and yearly recurring DDS patterns. (The DDS are spots forming in the frozen layer deposited on dark dunes; they appear at the end of winter and the beginning of spring and remain observable until summer in the polar regions of Mars.) The neutron measurements of Mars Odyssey confirmed our assumption that, besides carbon-dioxide ice, water ice must also be present in the frozen layer. The DDS-MSO hypothesis of the working group led by Gánti Tibor interprets the formation of the spots as the vital activity of Martian surface organisms (MSO). Our DDS results were presented at the 33rd LPSC in Houston, at the EGS conference in Nice, and at the Planetology Microsymposium of the Vernadsky Institute and Brown University in Moscow.

Space research and geometry

Our working group prepared a summary work in our mini-atlas series under the title Space Research and Geometry. In it we present important details of two branches of geometry related to space research: celestial coordinate systems, which we also give numerically for the case of the spacecraft that landed on Mars, and the “crystallographic geometry” of space-station construction. This second part introduces readers to the basics of building a spatial mosaic system that is suitable for creating spherical celestial bodies and for building a three-dimensional crystallographic structure. The second part also uses the methods of interactive computer graphics. The drawings and programs produced with Mathematica can be used for orientation in cosmic space and for designing three-dimensional shapes and structures that connect to each other in space. We have also produced international and domestic publications on this topic.

International cooperation

We reported on our work at several international and domestic conferences. The two most important were the 33rd Lunar and Planetary Science Conference in Houston and the 27th Symposium on Antarctic Meteorites in Tokyo. Our research group presented 15 papers (NASA) and 3 papers (NIPR) there, respectively. International contacts of our research group:

Other activities

We presented our cosmic-material collections in several lectures at the University of Szeged, the University of Pécs, the Berzsenyi Dániel College, the Székesfehérvár faculty of the Budapest Polytechnic named after Kandó Kálmán, and in several other towns of the country, also for interested members of the public. The doors are open to colleagues at the Tuesday-evening meetings of the Evolution of Matter Working Committee, and new university students are likewise welcome to join the Youth Space Research Group that builds the Hunveyor space probe.
