At the very end of 2012, MESSENGER obtained the final image needed to view 100% of Mercury’s surface under daylight conditions. The mosaics shown here cover all of Mercury’s surface and were produced by using the monochrome mosaic released by NASA’s Planetary Data System (PDS), as the base. The full resolution mosaics have been made available for download on MESSENGER’s Global Mosaics webpage today. The previous, low resolution mosaic covered only 99.9%.
Planetary maps and a globe created by members of ICA Commission on Planetary Cartography are featured in the “Solar System” room of the newly opened volcano museum in Celldömölk, Hungary. The museum, part of the Kemenes Volcano Theme Park, is located at the foots of the 280 m tall Ság-hegy, an extinct phreatomagmatic volcanic complex. The volcano museum was funded from a €1.4 million grant by the European Union. Content specialist curator of the exhibition was Dávid Karátson of the Eötvös Loránd University (ELTE), Budapest. The room presenting volcanism in the Solar System has two large map displays: a radar-mosaic of Venus and a topographic map of Mars, both in equirectangular projection, specifically created for the museum. Both maps has dozens of “hot spot” info boxes that summarize the particular feature’s geological characterics in English, German and Hungarian. The most exclusive map product is the 50-cm diameter hand-made globe of Io, the volcanic moon of Jupiter, that was produced by Zsófia Merk and Mátyás Gede of ELTE.
An international team of 10 institutions, lead by Ralph D. Lorenz of Johns Hopkins University, USA, created the first global topographic map of Titan, a moon of Saturn. They used Cassini RADAR SARtopo and altimetry data for use in Global Circulation Models, hydrological models and correlative studies. The map itself consists of 90% of interpolated data. The dataset revealed four prominent topographic peaks in a row in the southern hemisphere.
These results are published in the July issue of Icarus.
