Variations in the orbital parameters of Mars
Does there exist any software or algorithms for determining the
eccentricity, obliquity, and longitude of perihelion for Mars as a function of year? A similar item was developed by NASA's Goddard Institute of Space Studies for Earth, http://aom.giss.nasa.gov/srorbpar.html. I would be using these parameters as part of an solar insolation model. For my undergraduate senior project, I am building upon the work done is this paper, http://www.pnas.org/cgi/content/full/98/5/2132. They combined Viking pressure and temperature data with Mars Orbital Laser Altimeter topography data, and computed the fraction of the martian year during which pressure and temperature allow for liquid water to be stable on the martian surface. As for my research, I want to test for stability of water-salt solutions, http://www.spacedaily.com/news/mars-water-science-00a.html at different stages of Mars's orbital variation http://www.aas.org/publications/baas/v33n3/dps2001/310.htm. Some secondary, unrelated questions: Does anyone know where I can find the equations for the vaporization and melting curves of water in the range of 0-100 millibar and 173K to 313K? Also, given a variable distance, r, between Mars and the Sun what is the equation for the solar insolation on the cross section of Mars perpendicular to the incoming solar radiation? |
