Having completed the final operation, Wang Xiaodong packaged the resulting data and looked at Lu Zhou beside him. "The iterative calculation program for the main deceleration phase is finished. I've obtained the spatial coordinates of the perilune and apolune, as well as Chang'e 3's velocity direction. Should I email them to you?"
Without looking up from his handwritten calculations, Lu Zhou said, "Just send them to my QQ."
Wang Xiaodong said, "OK. What's next?"
"...A schematic of the satellite's lunar orbit and a geometric diagram of its landing trajectory. The data parameters are here, so I'll leave the plotting to you." Lu Zhou slapped an almost completely filled A4 sheet onto Wang Xiaodong's desk and immediately began the next stage of calculations.
After glancing over the data on the paper, Wang Xiaodong skillfully switched from MATLAB to SAS, which was more specialized for data visualization, and answered expressionlessly, "All right."
The two worked together with remarkable coordination, each fighting in the field they knew best.
At exactly noon, Lin Yuxiang quietly entered the computer room and set two servings of braised chicken rice and two cans of coffee on the table.
"Time to eat, geniuses."
Wang Xiaodong hurriedly stood up and accepted his portion, forcing a smile onto his poker face. "Thanks."
Lin Yuxiang naturally returned his smile, then walked over to Lu Zhou and held out the plastic bag in her hand. "Hey, yours."

At nine in the evening, Lin Yuxiang returned to her dormitory yawning. Around ten, Wang Xiaodong went back as well. As the main force tomorrow, he had to get enough sleep tonight.
By then, only a few people besides Lu Zhou remained in the computer room.
They
