Mars Sun-Synchronous Orbit
Does Mars offer the possibility of a sun-synchronous orbit? I'm
playing with an idea for orbiting reflectors to warm Mars and assist in terraforming. It would increase efficiency if the reflectors were never eclipsed. |

Yep: http://mars3.jpl.nasa.gov/mgs/overvu...f/mapping.html MGS has an afternoon orbit to give the sensors consistent lighting conditions. Karl Gallagher Northrop Grumman Space Technology |

I imagine J2 must be known at least fairly well for Venus, Mars, and Jupiter since we've placed orbiters around all of them. Appendix D of Vallado, "Fundamentals of Astrodynamics and Applications", 2nd ed, has them. Another very useful reference, which has the J2s among much other useful data, is Lodders & Fegley, eds, "The Planetary Scientist's Companion". -- MOST launched 1015 EDT 30 June, separated 1046, | Henry Spencer first ground-station pass 1651, all nominal! | |
