 ### Faster than real-time execution
 
-In some cases, you may be interested to simulate your spacecraft operating for an extended period. By default, PASEOS operates in real-time, thus this would take a lot of time. However, you can increase the rate of time passing (i.e. the spacecraft moving, power being charged / consumed etc.) using the `time_multiplier` parameter. Set it is as follows when initializing PASEOS.
