Mariner's Vally, the "Death Vally" of Mars.
The robots put in the last glass plate to seal us off from the cold vacuum of the Martian surface.
A great calm fell over the small section of Valles Merineris that was now air tight.
As luck would have it, it was a clear Martian day with the feeble sun directly overhead.
We went to work sealing all the cracks.
Holes were drilled in the valley walls and filled with the hot wires that would melt the ice in the frozen ground.
It began to flow back into the valley.
The bio tanker was only twelve months from landing.
The sealed in area needed to be relatively warm and wet when it arrived.
The faint sun made it easy to sleep, and the low gravity made it easy to work. We knew we would get it done on time.
