Chapter 125: Sol Two Hundred and Seventy-One, The Germans Have Eighty Years of Replacement Parts
Mai Dong got some sleep after lunch. Extravehicular activity was exhausting work. Furthermore, Mai Dong was only a weak, malnourished girl. She needed to maintain enough physical and mental strength to handle the upcoming tasks.
Tomcat and Tang Yue began their plans.
âIâve just contacted the United Space Stationâs system. The self-check report has been sent to me.â Tomcat opened the report on the computer. Tang Yue moved a chair over. âThe S1 solar panelâs revolving mechanism has malfunctioned. The actual reason might be due to a light sensor.â
The United Space Stationâs main solar panel and heat dissipation board were both installed on a framework. They werenât fixed in place but would rotate based on the angle of the sunlight to obtain the greatest amount of solar exposure. Responsible for this was a light sensor. It was a tiny gizmo that was installed on the solar panels.
âThe source of the malfunction is a disconnection in the control wire labeled C1002. It might be that the conducting wire has been cut or fallen off, but itâs not a major problem.
Tomcat entered the Mars United Space Stationâs power system and obtained the malfunction spot from the computerâs self-check. As an engineer, Tang Yue instantly understood the cause of the problem. It was indeed a disconnection and solving it was easy. They just needed to swap the conducting wire.
âThis part was designed by the Germans?â Tang Yue asked.
âNo, the light sensor supplier is a precision instrument company under General Electric.â Tomcat was taken aback. âWhy do you ask?â
âBecause if itâs a German product, they would definitely have dug a hole beside it, burying eighty years worth of replacement parts.â Tang Yue shrugged.
To fix such a malfunction on land would take only about ten minutes. But once such a simple procedure was placed in orbit, it became a rather difficult problem. Extravehicular activity was, to date, a rather dangerous matter. It was usually done by the experienced Commander with many others to provide assistance.
Now, with Old Wang and Thomp gone, Mai Dong needed to shoulder this mission alone.
As a result, Tomcat and Tang Yue had to do all the preparatory work for her.
âThe S1 battery bank is here.â Tomcat pointed at the block diagram on the computer with its claw. âItâs the innermost solar panel of this row of solar panels. It has a straight line distance of only thirty-five meters from the Crystal core module. Using the arm should be enough to send Miss Mai Dong all the way to the malfunctioning area. This is a common repair job.
âSwapping the conducting wire requires the dismantling of the sensorâs outer shell. The work involved is a little complicated. Mai Dong needs to bring along the repair kit.â Tang Yue leaned onto Tomcatâs shoulder, rubbed his chin and said, âIâve done it before, but it wasnât the S1 battery bank, but S4. Back then, Old Wang and I headed out to swap the aged light sensor. He was in charge of the repair work while I was responsible for handing him the tools⊠One will need to use a pair of scissors to cut open the lidâs outer skin. There will be four 8.0 mm Penta screws. Removing three of them allows the outer shell to be opened. When doing it alone, it will definitely be quite a frenzy.
âFurthermore, the darn screwdriver on the space station sucks, especially when youâre wearing gloves. It easily slips.â Tang Yue recalled. âBack then, Old Wang wrapped a band connected to the screwdriver to his wrist; otherwise, the screwdriver would have flown away.â
âHow long did it take you both to swap the sensor?â
âTwo and a half hours.â
âMake a detailed checklist of the steps involved.â Tomcat nodded. âWe shall prioritize fixing the solar panels. Extravehicular activity mustnât exceed four hours; otherwise, Miss Mai Dongâs body wonât be able to take it. We can do the inspection of the Eagleâs heat-resistant tiles later.â
Tang Yue got out a piece of paper and began listing down the detailed steps needed for the repair work based on memory.
Mai Dong was only a botanist without any space station repairing experience, so she needed Tang Yueâs and Tomcatâs guidance.
Humans truly had unlimited potential. A tiny lady like Mai Dong was truly capable to handle all kinds of matters, including heavy manual work.
âWe shall split the repair job into three stages. We will head out not more than four times.â As Tang Yue wrote, he muttered. The first extravehicular activity is to evaluate the situation and cut through the skin. This process will take about half an hour⊠How long will the entire return trip take including the exit and re-entry of the airlock?â
Tomcat did a count. âHalf an hour.â
âThen this stage will take an hour.â Tang Yue tapped the paper with the pen tip. âAfter this stage is completed, the space station would have circled behind Mars. Mai Dong can return to the space station to rest before preparing to head out a second time.â
âDid you take any breaks back when you were swapping the sensor?â
âNo.â Tang Yue shook his head. âOld Wang is a workaholic. We finished the job with torchlights, but Mai Dong isnât able to do it alone. Without enough help, itâll be easy to have problems crop up.â
Tomcat nodded and touched its ear.
âAfter the sun rises, you will head out a second time. The mission is to dismantle the sensorâs outer shell, remove the C1002 conducting wire, which is a dark red wire. It will be rather deep, and above it are two linesâB3074 and B3075. To swap C1002, you need to remove the two wires first. This will be a troublesome process and will take a lot of time. We arenât in a rush to swap out the wire during this stage. The three wires can be removed and brought back to the space station.
âMai Dong will need to take the repair tools for this job⊠She will need to use many things. I need to list down a tool sheet.â Tang Yue drew a checklist on the piece of paper. âThe tools used during the job mustnât be forgotten. Whatever is taken out needs to brought back in.â
âYou will have to remind her when the time comes.â
âI will.â Tang Yue pointed at the back of his hand. âDo you know what we did in the past? We stuck a slip of paper with all the things to take note of on the back of our hands. After finishing the job, we would look through the list.â
âBefore the sun sets, Mai Dong needs to return to the space station and prepare to head out a third time. In this third trip, Mai Dong will take the spare parts, taking the spare conducting wire and B3074 and B3075 to the sensor. Only after installing the conducting wire, closing the lid, and screwing down all the screws, will the job be considered complete,â Tang Yue continued. âIf she fails to complete the job on the third trip, there will still be a fourth⊠Of course, it will be best if everything goes smoothly and she completes the mission on her third trip.â
âAre there any contingency plans?â
âIf the inspection from our first extravehicular excursion is worse than we expected, making it impossible to fix it, we can only abandon the S1 battery bank. We will give up all the plans, and Mai Dong is to immediately return to the space station,â Tang Yue replied. âThe United Space Station can still operate normally without the S1 solar panel.â
Apart from a strategic abandonment of plans, they had no other contingency plans.
Tang Yue pushed the piece of paper that was filled with words to Tomcat.
Tomcat carefully looked through the form without missing a single word.
âOK?â
âOK!â
