Dead on Mars

Tang Yue moved the solar panels onto a cart and dragged it out of the garage. Tomcat had taken away ten solar panels, so now, Tang Yue was left with only thirty which wasn't enough to supply Kunlun Station with enough power to be fully operational. Therefore, Tang Yue had no choice but to shut down a considerable amount of power-draining equipment, leaving only the most basic life support and communications systems operational.

The Hab's temperature stayed at about –10°C and was undoubtedly a frozen cavern. With the Radiant Armor to resist the low temperatures, Tang Yue found it warmer moving the solar panels outside than staying indoors.

The sun had already risen and was like a huge light bulb that wasn't too hot. Tang Yue looked up at the sun and because Mars rotated in the same direction as Earth—rotating from west to east—with a similar tilt, the sun's trajectory across the sky resembled the trajectory on Earth. The sun rose in the east and set in the west.
