Welcome to the website of the Astrophysical and Geochemical Laboratory, a research group of the Research Center for Astronomy and Earth Science (CSFK). CSFK was established on 1st of January 2012, in order to exploit the resources from the fusion of the largest astronomical and the three largest Earth science institutes in Hungary. Ideal possibilities opened up for joint research and collaboration in Earth science and astronomy related topics, including the start of new research fields. Using this opportunity the Astrophysical and Geochemical Laboratory was established to apply Earth science related laboratory activities in astronomical and astrophysical topics. This field became more important in recent years as the connections used here give possibility to confirm and validate astronomical observations with laboratory data. Our main research topics are the analysis of Maritan surface, young lunar craters, asteroid surfaces, meteorites and the related early evolution of the Solar System. Beyond these, the group is working on planetary analogue locations on Earth, planning and preparation of planetary missions, testing and preparing instruments in laboratories to support them.


Advisory activity for the Hungarian Space Strategy Document
The Ministry of Foreign Affairs and Trade requested advisory activity from our research group in order to support suggestions for the compilation of the Hungarian Space Strategy document, which will orient the national space science and space technology activities as a framework of suggestions.

Contribution in the Comet Interceptor (Comet-I) ESA mission
Our research group has been contributing in the development of the idea, and in later the implementation of the Comet Interceptor misson, especially in the Comet Camera (CoCa) at Co-Investigator level. Comet Interceptor will be launched without the selection of a specific target beforehand, for the first time as a space mission. It will wait at an Earth Lagrange point till a comet is discovered, which will visit the inner Solar System for the first time, and might be even an interstellar comet.

During the work three Martian meteorites (Nakhla, Governador Valadares, Lafayette) were analyzed by Raman spectroscopy and back-scattered electron microscopy, mainly to search for and analyze secondary minerals formed by Martian water related acitivty. After the visiting research, the samples were acquired and further investigated in Hungary.

Melting inside an ancient planetesimal
Melting produced chondrule disruption was observed inside the NWA 1465 CV3 meteorite, which was produced in the relatively deeper interior of the parent body. In the sample strong mechanical deformation, two generation of opaque mineral formation, and results of resorption plus melting were identified. The results fit into the joint CV-CK parent body hypothesis with heterogeneous internal structure at this ancient planetesimal. The results were published in Planetary and Space Science.

Student research work to predict liquid water on Mars
Pál Bernadett undergraduate master student at ELTE astronomy is working on to predict the ideal locations and periods for the emergence of microscopic liquid water on Mars today, to support the research work of ExoMars rover. According to the current phase of the work, nighttime periods might be favourable for the liquid even at low latitude terrains. She presented her results at the International Conference of Physics Students (12-19th August 2015, Zagreb) where she received the second best poster award of the meeting.

Signatures of plastic deformation in a meteorite
Unusual, elongated dark stripes were identified and analyzed by our research group in the NWA 3118 CV3 meteorite. These ripple-like features in the matrix are longer than 0.3 mm and resemble certain chondrule rims - although several of them occur without chondrules. If similar features will be identified in other meteorites, revision will be necessary on the origin of certain chondrule rims. The ripple-like features might formed just before the solidification of the meteorite's material and oriented crystal growth could also contributed in their origin. The related paper was published in Planetary and Space Science.

Microscopic chemical processes on Mars
On the surface of the red planet the only possible phase for the occurrence of liquid water is at microscopic scale today. Our group in collaboration with the ESA PECS Co 4000105405 (No. 98076) project's researchers analyzed these locations. Although the chemical conditions in this so called interfacial water differ substantally from that of the bulk volume, using reaction kinetic computations, we predicted the decomposition rate of H2O2 at these locations. Based on the result the decomposition is not ideal today, but could be much better if conditions change little on Mars. The occurence of H2O2 as the strongest oxidant on the surface is of high importance because it influences several chemical processes, and habitability too. The related paper can be read in Planetary and Space Science.

Infrared microscopic analyis of meteorites
Using the FTIR Vertex 70 and Hyperion 2000 infrared spectroscope and microscope (provided by the Infrastructure Fund of the Hungarian Academy of Sciences) new results and related methodological developments were presented by Ildikó Gyollai (Thermal and Shock Metamorphosis in NWA-5011 L6 Chondrite) and Ákos Kereszturi (Infrared spectral analysis of chondrule alteration in NWA 2086 CV3 meteorite), furthermore the infrared study of aqueously altered meteorites by Sándor Góbi ("Investigating the hydration of CM2 meteorites by IR spectroscopy") in Sopron 1st of November, 2014 at "The Modern Analytical Methods Applied to Earth and Planetary Sciences" international conference.

Microgravity geology - where shall we land on an asteroid?
Exotic processes dominate on the surface of minor bodies with weak gravity. Although this so-called microgravity geology is a poorly explored field yet, it already helps in the planning of landing sites for next asteroid missions. Our group compared the different surface unit types on asteroids in order to identify ideal regions for the planned ESA mission of MarcoPolo-R. The related paper was published in the Planetary and Space Science.

Astromineralogy Workshop III.

Altogether 37 participants took part in the meeting, including 4 foreign invited guests. During the workshop the emphasis was given to the expected full ESA membership of Hungary, and in connection with this topic Luigi Colangeli, head of ESA Solar System Division gave an overview presentation. The website of the MTA also published a report on the event.

Alteration processes in the CV chondrite parent body based on the analysis of NWA 2086 meteorite
During the analyzis of the NWA 2086 CV3 type meteorite, members of our research group identified rims with double layered structures were around several chondrules, which, in at least one case, were attributed to an accretionary origin. The rim’s outer parts with a diffuse appearance were formed by in situ chemical alteration. This specimen demonstrated both type of processes that took part in the rim formation of these primitive meteorites. The related paper appeared in Meteoritics and Planetary Science, providing more insight into the buried source region of these meteorites.
