It will takemonths for Lowell to send a rescue ship from Earth, but the stranded landing crew have supplies for less than a year and need to find ways to extend the life support system. The main problem is the thermoelectric power generator, since air and water recycling require electrical power. Since the lander is damaged beyond repair, it no longer requires fuel, and Sagan the mission geologist proposes to use what is left to power an improvised silicate reactor to produce methane and water vapor from the martian soil. They try to build it, but the landing engines and propellant tanks prove to be too damaged to salvage.The landing crew tries to find ways to save electrical power, but even draconian measures will only extend the life of the generator to fourteen months. The required lifetime can be attained only if the crew is reduced to two astronauts. Sanchez, the new commander, decides that she, Sagan and Rodrigo should abandon the craft, since their specialist skills are less important to the survival of the mission. They don their spacesuits and walk to the edge of the Valles Marineris valley, not far from the crash site. Recent radar scans from the orbiter reveal a mazelike structure hidden below a thick cloud of water vapor in the Valles Marineris. The structure appears artificial and is virtually identical to another one near the martian south pole. The three astronauts try to reach the bottom of the valley before they run out of oxygen. ........
