A lissajous orbit about L2 provides an ideal observation geometry for the SIRTF mission. To avoid contamination, the baseline SIRTF spacecraft uses a low thrust helium cold gas propulsion system. Three types of maneuvers are required for the L2 mission: trajectory correction maneuvers (TCM), lissajous orbit insertion maneuver (LOI), and orbit maintenance maneuvers (OMM). Analysis shows a total thrust level of 0.1 N is sufficient to achieve LOI and the smaller OMMs. Rough estimates indicate thrst level greater than 1N is needed to perform the TCMs. A hybrid hydrazine/cold gas propulsion system provides a possible solution.
