Astrodynamics,luence the higher altitude orbital motions. Solutions for such motions are achieved by solving restricted three body problem, considering the Earth’s gravity force as the central gravity field whereas the perturbing gravitational force is from the third body such as Moon. Depending on the type of tr

Space Transportation Requirements and Launching of Satellites, influence of Earth’s gravity field and aerodynamic drag during atmospheric flight phase causes the energy loss and to compensate these losses extra energy has to be provided. All these effects need to be considered for configuring STS to provide the necessary energy to the satellite. The satellites

Mission Design,ds and radio visibility for continuous tracking coverage during ascent phase are other essential parts of mission design. There are number of constraints like thermal loads on the spacecraft, the vehicle subsystems during ascent phase and jet plumes of reaction control system thrusters interacting w
