- 3 July 2007
Every three years the IAU/IAG Working Group on Cartographic Coordinates and Rotational Elements revises tables giving the directions of the poles of rotation and the prime meridians of the planets,…
Rain, winds and haze during the Huygens probe's descent to Titan's surface
- M. Tomasko, B. Archinal, R. West
- Physics, GeologyNature
- 8 December 2005
Spectra and high-resolution images obtained by the Huygens Probe Descent Imager/Spectral Radiometer instrument in Titan's atmosphere reveal the traces of once flowing liquid, and like Earth, the brighter highland regions show complex systems draining into flat, dark lowlands.

A Radio Reference Frame
- K. Johnston, A. Fey, D. Shaffer
- Physics
- 1 August 1995
A catalogue is presented based on the radio positions of 436 extragalactic sources distributed over the entire sky. The positional accuracy of the sources is better than 3 milliarcsec (mas) in both…
High-resolution topomapping of candidate MER landing sites with Mars Orbiter Camera narrow-angle images
- R. Kirk, E. Howington-Kraus, J. Barrett
- Environmental Science, Physics
- 1 December 2003
[1] We analyzed narrow-angle Mars Orbiter Camera (MOC-NA) images to produce high-resolution digital elevation models (DEMs) in order to provide topographic and slope information needed to assess the…
Report of the IAU Working Group on Cartographic Coordinates and Rotational Elements: 2015
- B. Archinal, C. Acton, I. Williams
- Geology, Physics
- 23 February 2018
This report continues the practice where the IAU Working Group on Cartographic Coordinates and Rotational Elements revises recommendations regarding those topics for the planets, satellites, minor planets, and comets approximately every 3 years, and recommends that planning and efforts be made to make controlled cartographic products.
