Tomcat left the crutches with Tang Yue and got him to make slight adjustments for Mai Dongâs height. As for Tomcat, it headed out to check on the landing zone. The Isidis Planitia was flat, so Kunlun Stationâs surroundings was a naturally good landing zone. The Mars Landing Project had demarcated five landing zones with Kunlun Station in the center. They were designated L1 to L5. In the past, the lander and cargo spacecraft could directly descend onto the desert.
With the Mars Landing Project having gone on for a few decades, there were a dozen disposable spacecraft in Kunlun Stationâs vicinity, causing three of the five landing zones to be abandoned. Tianzhou 37 was to land at L4, neighboring the Eagle, fifty meters in front of Kunlun Station.
âMr. Cat went out?â
âYeah. Itâs inspecting the cargo spacecraftâs landing zone.â Tang Yue turned to sit on a chair. He placed the two crutches level across his knees and said, âLass, can you estimate your present altitude?â
âBut I just did it the previous orbit.â
âThat was the previous orbit,â Tang Yue emphasized. âThe altitude of the previous orbit and the present orbit will be different. Every orbit might lead to changes. We need to monitor the United Space Stationâs altitude in real-time.â
âOkay⊠Wait a moment.â The comms fell silent for a few minutes. âApproximately 110 kilometers. Itâs still the same. There havenât been any changes.â
âRemember, 100 kilometers is the safety threshold. 80 kilometers is the danger threshold,â Tang Yue reminded her.
âBut Mr. Cat said 60 kilometers is the danger threshold.â
â60 kilometers isnât the danger threshold. Itâs the point of no return!â Tang Yue corrected her. âNo matter what, you canât let it fall to 60 kilometers.â
âBut what can we do?â
Tang Yue was stumped.
How are we to ensure that the United Space Station maintains a sufficiently safe altitude?
This was an unsolvable problem. Regardless of 80 kilometers being the danger threshold or not, or whether 60 kilometers was the point of no return, even if they could sense that the space station was about to crash ahead of time, there was nothing they could do to save it.
Tomcat had already told Tang Yue that from the moment the electric rocket expended all its propellant, the space stationâs outcome was destined. This was akin to having handed in oneâs test script after the end of a test. Before the results were announced, no action could influence the final results. Under such circumstances, the best choice of action was to sleep all day until the results were released. It saved one from suffering prolonged anxiety.
The two fell silent before the girl broke the silence. âToday is the sixth sol.â
âYes, itâs the sixth sol today,â Tang Yue said.
âItâs already the sixth solâŠâ The girl sighed softly over the comms. âMy watch here is broken. I donât even know what time it is. In less than an hour, the sun will rise and set⊠Also, Iâm starvingâŠâ
âHow much food do you have left?â
âThe last biscuit.â
âHow do you have such an appetite?â
âI⊠I⊠There werenât a lot of biscuits in the space station to begin with. Iâve been rationing it properly, alright?â The girl didnât give in. âYesterday was the worst. I was so hungry I couldnât sleep. When I woke up this morning, I no longer felt anything other than feeling dizzy. Perhaps itâs a result of low blood glucose⊠Tang Yue, you need to realize you are speaking to a patient with hypoglycemia.â
âSo?â
âThatâs why you need to be sweeter with your words!â
âŠ
âI say, Tang Yue.â
âYes?â
âDidnât Mr. Cat say that the remaining lifespan of the United Space Station is seven to eleven sols?â
âYes.â
âTomorrow is the seventh sol.â
âDonât worry. It will be fine,â Tang Yue consoled her. âBased on your present estimated altitude, the United Space Stationâs descent is slower than we expected. Not only will it be okay tomorrow, but it will also be fine the sol after tomorrow. It might drop to 80 kilometers on the tenth sol. But by then, Tianzhou 37 will have arrived. We canât save the space station, but we can save you.â
âCan it still be saved beneath 80 kilometers?â
âYes! Donât even say 80 kilometers! Even 60 kilometers will do!â Tang Yue took out a few pieces of paper from the stack in front of him. He unfolded them onto the table. On them were equations and numbers. âIâve done the math⊠Tianzhou 37 has the ability to safely enter the atmosphere. As long as we are gutsy enough and we control it precisely enough, we can dock during a high-speed plummet!â
âIs⊠it possible?â The girl was somewhat alarmed.
âOf course! Of course! Lass, listen to me, listen to meâŠâ
âYeah, yeah, go ahead.â
âTianzhouâs body is strong enough. And the Crystal module is the strongest module in the United Space Station. At an altitude between sixty and eighty kilometersâif the atmospheric conditions are idealistic enough⊠If the atmospheric conditions are idealistic enough because, at this altitude, it hasnât really reached an entry altitudeâŠâ
Tang Yue took out a pen and quickly wrote on the paper. Over the past two nights, apart from playing cards, he had been considering this problem. He had racked his brains, losing copious amounts of hair in the process.
Even though Mai Dong couldnât see the content on Tang Yueâs paper, he reproduced his calculations to boost his confidence. He had made a rigorous calculation and was not simply relying on empty mantras.
âWithout a doubt, the United Space Stationâs attitude is completely out of control, but Tianzhou can be controlled. Our only hope is in Tianzhou! We can control the spacecraft to approach the Crystal, and choose a docking orientation with the head facing front⊠It might sound incredible and fantastic, but my calculations support this outcome. This operation will be extremely difficult, but itâs doable. I definitely canât, but Tomcat probably can.
âWe have all of Tianzhouâs data. During this process, as long as the temperature doesnât exceed 1000 K, and the heat density doesnât exceed 300 KW/mÂČ, it will have zero effect on the spacecraft. Based on past data, this stageâs highest temperature is actually only 800 K. We can complete the rescue before the space station reaches 60 kilometers. As long as you work with us, the entire process wonât exceed three minutes.â
Tang Yueâs pen moved swiftly as he spoke so quickly that he was almost rambling incoherently. Thankfully, the messed up order didnât affect the message he was trying to convey.
âThe real heat zone is at an altitude below 40 kilometers, but by then, Tianzhou will have already rescued you. Following that, Tianzhou will immediately begin normal landing procedures. At forty kilometers, it will enter the Martian atmosphere. The empty United Space Station will then burn up in the atmosphere while the cargo spacecraft will land you safely! The only problem is that the propellant has been greatly expended, so Tianzhouâs final descent will be rather fast. It might damage the landing gear.
âThereâs a problem that doing so might not guarantee that you land near Kunlun Station. However, Tianzhou has sufficient resources. You can stay in there eating and drinking while awaiting rescue.â
Tang Yue regurgitated his entire plan in one go, leaving him somewhat breathless as he waited for Mai Dongâs reply.
The girl held her breath.
âYou calculated this by yourself?â
âYes.â
âDoes Mr. Cat know?â
âI havenât had the time to tell it.â
âTang Yue⊠You are only a mechanical and electrical engineer.â
âSo what?â Tang Yue said. âIâm telling you, a proper aeronautical engineer wouldnât dare to, but I dare!â
âBecause doing so might destroy Tianzhou.â Mai Dong instantly noticed the crux of the issue. âItâs too risky.â
Tang Yueâs idea was indeed out of this world. He wanted Tianzhou 37 to dock with the Crystal under extremely unstable conditions. It was extremely risky. Any mishap would cause them to suffer a double loss.
âBut this is the only way of saving you, lass,â Tang Yue said. âWhat we should care about is not the risk, but hope. As long as thereâs a sliver of hope, itâs worth it to put in 100% of the work or more.â
