Coordinates of Named Features on Io Updated to Voyager/Galileo SSI

Monday, August 20, 2012

In 2012, the coordinates of the named features in the Io portion of the International Astronomical Union Gazetteer of Planetary Nomenclature were updated from values from historical sources to values in the Voyager/Galileo SSI control network. The purpose of this work was to facilitate the identification of named features on Io. Dots representing the center coordinates of named features should fall in the centers of the features when displayed on any map product based on the Voyager/Galileo SSI reference frame. The extents and sizes of the named features were also updated; these data are approximate and are intended solely to give the user sufficient information to identify named features and their rough extents.

This new set of coordinates was derived using ArcMap version 10.0 and the 2011 Geologic Map of Io by David Williams et al. Vectors describing feature extents are based on the geologic contacts shown on this map. We are also grateful for help and advice provided by Dr. Rosaly Lopes and Dr. Jani Radebaugh.

The Io portion of the Gazetteer of Planetary Nomenclature web site now defaults to showing feature coordinates in the frame of the Voyager/Galileo SSI control network. The original coordinates (from unknown sources) are still retained in the gazetteer and can be viewed by selecting the desired coordinate set from a dropdown menu on the feature pages. The "Unknown" coordinates are now considered archival and will not be updated with new names or changes to approved names.

Nine New Crater Names Approved on Mercury

Monday, July 30, 2012

For details, see the list of Mercury feature names and the map of Mercury quadrangle H-1 in the Gazetteer of Planetary Nomenclature.

New Name for a Dorsa on Mars

Friday, July 27, 2012

The IAU Working Group for Planetary System Nomenclature has approved the name Aeolis Dorsa for the Martian feature located at 5.0S, 152.6E. For more information, see the map of MC-23 in the Gazetteer of Planetary Nomenclature.

New Name for a Chasma on Venus

Friday, July 20, 2012

The southern segment of Devana Chasma on Venus has been renamed Rona Chasma. For more information, see the maps of V-29 and V-41 in the Gazetteer of Planetary Nomenclature.

New Names for a Crater and a Colles on Mars

Friday, July 20, 2012

The IAU Working Group for Planetary System Nomenclature has approved the names Lederberg for the Martian crater located at 13N, 314E and Ulysses Colles for the colles at 6.1N, 236.9E. For more information, see the maps of MC-9 (for Ulysses Colles) and MC-10 (for Lederberg) in the Gazetteer of Planetary Nomenclature.

Martian Crater Named Moanda

Thursday, July 5, 2012

The IAU Working Group for Planetary System Nomenclature has approved the name Moanda for the Martian crater located at 35.93S, 320.0E. For more information, see the map of MC-26 in the Gazetteer of Planetary Nomenclature.

Friday, June 15, 2012

The Working Group for Planetary System Nomenclature has approved 12 new names for small craters on the Moon: Albert, Borya, Gena, Igor, Kolya, Kostya, Leonid, Nikolya, Slava, Valera, Vasya, and Vitya. For details, see the map of LAC 24 and the Lunokhod-1 traverse map in the Gazetteer of Planetary Nomenclature.

Coordinates of Named Lunar Features Now Available in LOLA Reference Frame

Monday, June 4, 2012

On June 4, 2012, coordinates of the named features in the lunar portion of the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN) Gazetteer of Planetary Nomenclature were updated. Previous coordinates were based on maps using the Unified Lunar Control Network (ULCN) 2005 coordinate reference frame. The new coordinates are derived from maps made in a Lunar Reconnaissance Orbiter (LRO) Lunar Orbiter Laser Altimeter (LOLA) coordinate reference frame. These reference frames are referred to the mean Earth/polar axis reference coordinate system for the Moon. The updated coordinates will facilitate the identification of named lunar features on images derived from LOLA topography. Dots representing the center coordinates of named features should fall in the centers of the features when displayed on any map product based on a LOLA reference frame.

The extents and sizes of named features were also updated; these data are approximate and are intended solely to give the user sufficient information to identify named features and their rough extents. A link to a more precise lunar crater database (now in preparation) by D.T.W. Buckingham, B. Salimkumar, and N.G. Barlow will be provided when available.

This new set of coordinates was derived using ArcMap version 10.0 as a display tool, a lunar hillshade image based on LOLA topography (LDEM_128.jp2, 128 pixels/degree or 237 m/pixel, released December 2011, http://pds-geosciences.wustl.edu/missions/lro/lola.htm), the underlying LOLA coordinate reference frame used in the creation of that topographic model, and a Lunar Reconnaissance Orbiter Camera (LROC) Wide Angle Camera (WAC) image mosaic (released November 2011, http://wms.lroc.asu.edu/lroc/global_product/100_mpp_global_bw). Feature boundaries were determined using both images, but the features were aligned to the LOLA hillshade image where there were slight discrepancies.

We greatly appreciate being able to use these high quality, high resolution products of the LRO LOLA and Camera (LROC) instrument teams, and recognize and acknowledge the substantial, lengthy, and difficult work that was done by the LRO Project Team and Mission, the LRO development team, and the LRO Science Operations Center that made the creation of these products possible.

The lunar portion of the Gazetteer of Planetary Nomenclature web site now displays feature coordinates in the LOLA reference frame. The original coordinates (from unknown sources) and the ULCN 2005 coordinates are retained in the gazetteer and can be viewed by gazetteer users by selecting the desired coordinate set from a dropdown menu on the feature pages. The “Unknown” and ULCN 2005 based coordinates are now considered archival and will not be updated with new names or changes to approved names.
