It's summer time where the Phoenix lander sits at what would be the Martian arctic circle. Its mission is limited to only around 92 (Earth) days because, even as it sits there in Mars's summer season, the high temperature never exceeds something like 20 degrees (F) below zero and, at night, well, your ice cream would never melt. EVER! They tell us that, as winter sets in on Mars, the Phoenix lander will become entombed, yes completely covered in snow and ice --mostly frozen carbon dioxide-- effectively "killing" the immobile robot about three (Earth) months from now. When summer returns to the northern regions of Mars, the lander will be exposed again. The solar panels will generate electricity again. And NASA will listen. There is a small chance Phoenix will stir back to life and, if it does, her handlers don't want to miss it! In the mean time we sit and watch the show from the warmer climes of Earth and marvel.
