Abstract : Using a simplified approach, the possibility of Phobus or Deimos being used as an orbital space station is investigated. Numerical results indicate that the velocity changes for rendezvous are approximately 10,000 feet per second. The use of multiple phasing ellipses for transplanetary injection is then considered. It is shown that the delta V using this method is the same as the delta V from a circular parking orbit at the periapsis altitude of the ellipse. An example of a transfer from Earth to Mars is given using the 'patched-conic technique' and assuming coplanar circular orbits. The orbital capture and rendezvous procedure are also investigated and include the delta V for capture, plane change, periapsis drag perturbation, and phasing; examples are given for Mars. (Author)
