章 1236: Mars Rescue

"How long until the rescue?"

"If you say a few words less, maybe we can last a few more hours." Wang Qiang said wearily as he looked at the remaining power and oxygen on the holographic screen.

The oxygen in the rover came primarily from two systems.

One was an oxygen tank placed in the trunk, and the reserve inside could provide oxygen for a crew up to a week. The other was the carbon fixation device that automatically started when the oxygen tank was empty. The device consumed electrical energy to convert carbon dioxide into oxygen until the battery is depleted.

In an optimal scenario, the device could maintain oxygen for two weeks.

However, now, five days had already passed.

Looking at the fiery red desert outside the window, and the "worm" that crawled out onto the surface from time to time, Wang Qian had a bitter smile on his face.
