One of the objectives of the MRO mission is to use the High-Resolution Imaging Science Experiment (HiRISE) to provide 50 cm/pixel images of future Mars landing sites. To achieve such detail, MRO must meet some very challenging target-relative pointing and pointing stability requirements. A combination of analysis, operational constraints, and spacecraft design modifications were utilized to ensure that the necessary pointing requirements will be met.
