Well, with perhaps a few more weeks of tilt-enhancing drives to go and then settling in for the winter, I thought it might be a good time to have a thread dedicated to ideas and observations that will come. It's likely that we won't hear much from Spirit during the coldest part of winter (April-June) possibly longer. There'll hopefully be beeps to tell us that she's still alive.
Already there are plans for radio science and determining the fluidity or otherwise of the Martian core, plus weather observations, surface changes etc. What else could you think of that Spirit could do? Remember that she's not going anywhere (vonBraun is out) In the meantime, have you sent your postcard to Spirit yet?! It's a great idea from the Mars outreach team. http://beamartian.jpl.nasa.gov/spiritpostcards What would you say to Spirit? |

Spirit had an all time low of 86 whr during the regional dust storm of November 2008. That's an unsustainable level of course, but it only lasted for a few days and Spirit was able to live off her batteries until the situation improved.
I think Opportunity's lowest power level was around 128 whr during the global storm in July 2007. I don't know how low they expect the power levels to get for Spirit this winter, but I would imagine it doesn't matter that much. Whether the batteries take three days or three weeks to drain, she will still need to endure some lengthy period of being subjected to the unmitigated chill of winter. |
