Mars24: Acknowledgements & References


We thank members of the Mars Climate Orbiter and Mars Exploration Rover projects at NASA's Jet Propulsion Laboratory for their encouragement over many years on behalf of the development of our solar timing algorithms and Mars24 sunclock.

We thank members of the Mars Phoenix project at NASA/JPL and the University of Arizona and members of the Mars Science Laboratory project at NASA/JPL and the Johns Hopkins University with more recent updates to Mars24.

Sunclock Map Images

The "MOC_MOLA_NGS_Map" sample map imagery is derived from an image created by Malin Space Science Systems by combining Mars Global Surveyor (MGS), Mars Orbiter Camera (MOC) and Mars Orbiter Laser Altimeter (MOLA) data for a map to be used by the National Geographic Society. The base image was obtained from the MOLA Science website.

The color topography shade map image was created by the MGS MOLA team and was also obtained from the MOLA Science website.

The "VIS_MDIM_Map" sample map image used in the sunclock was obtained from the USGS Astrogeology Research Program PDS Imaging Node and is a combination of Viking project Visual Image Subsystem (VIS) color imagery with Viking Mars Digital Image Model Version 1 (MDIM1) data.

Landing Site Panorama Images

The local panorama images at the recent lander sites are derived from panorama images released by the lander projects.

The MER-A panorama uses image PIA05199 in the NASA Planetary Photojournal, and the MER-B panorama uses image PIA05049. These images are courtesy NASA/JPL/Cornell.

The Phoenix panorama combines two images, the black and white image PIA10733 released May 29 and color image PIA11007 released July 31, 2008. The Phoenix images are courtesy NASA/JPL-Caltech/University of Arizona/Texas A&M University.
