1. The problem statement, all variables and given/known data In the not-too-distant future astronauts will travel to mars to carry out scientific explorations. As part of their mission, it is likely that a "geosynchronous" satelite will be placed above a given point on the Martian equator to facilitate communcations. At what altitude above the surface of mars should such a satellite orbit? (the Martian day is 24.6229 hours. other relevant information can be found in appendix c.) At what altitude above the suface of mars should such a satellite orbit? 2. Relevant equations I know that we should use Universal Gravitation (F = GmM1/R^2). 3. The attempt at a solution r = (GMT/2pi)^.5 i did this to solve for the radius, converting the Maritan day into seconds first.
