Name of person filing report: Kasey Hilton

Non-nominal systems: Spirit rover battery; Power system

Notes on non-nominal systems: Spirit and Curiosity were used today in EVA and Spirit returned with far less battery than Curiosity even though they traveled the same distance in the same conditions; The power system was malfunctioning when the generator was being turned on.

The system inside the ScienceDome was making noises indicating that there was an issue and the system could not switch from the batteries to the generator. As of 19:18 the generator shut off and we are left on battery power until morning. We are limiting the use of electricity until the morning when the sun comes out to recharge the batteries.

Generator (hours run): 16hr 56min; Turned on last night (01Jan2019) at 16:19; Turned off this morning (02Jan2019) around 9:15; Attempted to turn on tonight (02Jan2019) at 17:45, but the generator shut off around 19:00. The generator will not be running overnight.
