This solution is much simpler than uploading an orbit calculation program from the ground, and then finding a way to accurately control the flight speed of Tiangong.
Experts on the ground even directly pointed out several equatorial landmark points on the surface of Mars and asked Xiao Song on the Taishan to be responsible for choosing the specific point to fix the Tiangong in the Mars synchronous orbit.
With the spacecraft core there, the conditions were too convenient. Of course, Xiao Song directly chose the point closest to the base on the surface of Mars. Then Wang Qinyun jumped out to fight for the right to control the Tiangong into orbit.
Wang Qinyun had been unable to return the Tiangong to its scheduled low-Earth orbit before, which probably made Wang Qinyun a little bit upset.
Su Qin and Xu Siqi finally decided that Wang Qinyun would do the job. Taishan would be watching anyway, and in fact, the job was not difficult to do.
What Wang Qinyun had to do this time was actually to fly with the Taishan and maintain a determined position next to the Taishan. The altitude and speed could only be determined by the equipment on the Taishan. If Wang Qinyun didn't come out to grab this operating position, Xu Siqi was originally going to directly use the formation function of the core of the spacecraft to complete the work.
Before the official operation can begin, Taishan still has to return the three astronauts to Tiangong. Because the three astronauts only brought one set of extravehicular spacesuits, if this was not done first, they would not be able to go back after the Tiangong was in place and the core of the spacecraft was dismantled.
However, this means that after the core of the spacecraft is dismantled, the hole cannot be filled in a vacuum state.
After the three astronauts entered the capsule, Wang Qinyun stayed there and was responsible for controlling the core of the spacecraft on the space station. Xu Siqi returned temporarily. Later, he would be responsible for taking Xiao Song over to block the core of the spacecraft that was exposed after it was dismantled. That hole.
According to the previously agreed method, Wang Qinyun immediately turned off the protective cover at the core of the spacecraft, allowing Tiangong to return to the vacuum.
Then she adjusted the posture of Tiangong so that its solar panels faced the sun. Then Wang Qinyun found that she had nothing to do.
According to what was agreed, Wang Qinyun's final mission should be to fly with Taishan until Taishan moves to the position planned for Tiangong in the synchronous orbit.
However, the Taishan did not move for a long time, and Wang Qinyun was so angry that she finally took an extraordinary move.
Su Qin, Xu Siqi and Xiao Song were shocked when they heard Wang Qinyun's voice on the radio.
Wang Qinyun, who is wearing armor and staying in space, cannot be equipped with a radio. After starting up the infrequently used translator in the command cabin, a few people figured out what was going on.
It turned out that Wang Qinyun was sulking alone and decided to ask what happened. But she was smart enough not to use up her fighting spirit and fly back to the Taishan. Instead, she ran directly to knock on the door of the Tiangong node module. The astronauts in the cabin had never experienced such a thing, and they actually sent her away without calling the Taishan first. Put it in.
Wang Qinyun thus achieved the achievement of being "the only person in history to knock on the door and enter the space station"!
However, Su Qin and Xiao Song later believed that Wang Qinyun had planned this for a long time. She wanted to enter the Tiangong, which did not require the core of the spacecraft and could fly inside to take a look. She had not bothered to go in before when she was in Earth orbit.
As for why Wang Qinyun asked why the Taishan remained motionless, Su Qin said that there was actually no need to move it.
Before Tiangong entered the Mars orbit and came to the vicinity of Taishan to form a real formation at close range, Taishan, as the core body of the formation, had quietly maneuvered into the Mars synchronous orbit.
Now less than 1,000 kilometers away is the booming light pillar in the core of the city on the surface of Mars. The light beam now looks like a laser sword piercing the sky straight from the air.
Taishan is now monitoring whether the hull and landmarks on the surface of Mars have remained relatively stationary. This requires continuous observation for a period of time. If it can be determined that relative stillness has been achieved, then it can be considered that Tiangong is also relatively stationary and floating near Taishan. It has entered Mars synchronous orbit.
I have to admit that these things are boring enough, and it is not a problem for Wang Qinyun to stay there and wait.
However, Su Qin felt that the orbital error was not big now. Since Wang Qinyun was bored, he might as well just start the next step, turn off the core of the spacecraft over there, and start to observe how much the Tiangong would compare to the Taishan when it was floating freely. Position offset.
You must know that on Earth before, the fixed-point levitation function of the core of the Taishan spacecraft was very reliable. It could remain motionless relative to the ground at 40 degrees north latitude. Therefore, although it must be verified, as long as the altitude is correct, the current Taishan Being in a Mars synchronous orbit should be certain.
At this time, the astronauts on the Tiangong had new suggestions.
It turns out that Tiangong is not completely devoid of maneuverability. At least it has complete attitude control capabilities. If it must maneuver, a Shenzhou spacecraft docked on the node module can also provide considerable thrust.
This Shenzhou spacecraft has always been used as a lifeboat for the three astronauts. It was reluctant to use it when trying to restore the orbit control of Tiangong in Earth orbit, but now it can be used.
It is impossible for this Shenzhou spacecraft to return the three astronauts to Earth anyway, or even land on Mars.
With these, coupled with the radar and photoelectric measurement equipment on the space station, as long as Taishan is sure that it is almost in synchronous orbit, and there is no need to carry out any large-scale maneuvers, the space station can completely correct its orbit on its own.
With that said, the mission quickly advanced to the final step - closing and dismantling the core of the spacecraft, and then plugging the hole in the space station bulkhead.
Xiao Song had already found some pieces of aluminum on the Taishan and planned to take them to the space station to try the metal spell. However, she was not mentally prepared to set off so soon. She followed Xu Siqi and boarded the small landing craft again. He looked frightened when he saw the planet.
By the time Xiao Song arrived at his destination in a daze again, the diligent Wang Qinyun had already turned off the core of the spacecraft.
Fortunately, she was not diligent enough to directly remove the core of the spacecraft, otherwise the lives of several astronauts in the cabin would be in danger now.
Xu Siqi had already turned off the gravity field on the core of the spacecraft on Little Star's side halfway. Xiao Song was already dizzy and wanted to vomit. Xu Siqi quickly installed the core module of the space station without stopping. The bulkhead at the core of the spacecraft He incorporated the protective shield on his side and then made a gesture to Wang Qinyun.
