re: Great News
The power loss from the faulty heater has been known and talked about since the day Opportunity landed. Basically the heater and thermostat work fine, they just can't turn it completely off. It is always regulating the temperature of the arm. This wastes power in the middle of the night when it's cold and they aren't using the arm. They have a work around they are going to start using to get the heater to turn off at night.
