NGST Mission Simulator | The NGST Mission Simulator (NMS) can be used to calculate exposure times or sensitivities for observations of astronomical targets for a specific design of the NGST observatory and science instruments. The NMS can also be used to calculate the Mission Elapsed Time (MET) for a suite of observing programs, by optimally scheduling those observations and taking into account the associated overheads. |
