Trajectory analysis and mission planning for the Google Lunar X-Prize mission was completed using an Astrogator mission control sequence in AGI’s Satellite Tool Kit (STK) program. Astrogator allows space mission planning by piecing together various segments such as launch, propagate, maneuver, etc. Astrogator also includes a targeter tool which, using a differential corrector scheme, allows one to iteratively converge on a desired mission design based on a set of constraints. Below is an image of the STK Astrogator mission control sequence.
