After the astronauts enter the portal, the time is measured. Referring to the round-trip time of the aircraft test, the portal itself still has a certain time loss. For a thirty-second mission, it takes about eighty seconds for the astronauts to come back.
However, in actual operation, although there were no accidents, it still took nearly two hundred seconds for the astronauts to return here. With a little more time, everyone would be ready to push astronaut No. 2 up.
A bunch of people rushed up to help the astronauts get out of their spacesuits and pulled them aside to rest and check their bodies.
The Kingdom has almost no official investment in medicine, and the formal development of community clinics only began during the construction of Little Bear City. Relying on the inheritance of the second generation of the disaster, everyone still knows simple physical examinations such as measuring blood pressure and heart rate. In addition, with local knowledge of herbalism and potions, astronauts' long-term cooperation during the training period can be regarded as "familiar objects". Physical examinations are not Very troublesome.
After a break for the physical examination, it took twenty minutes for the command staff to go up and ask questions.
The amount of information recognized by the naked eye is much greater than those without intelligent support at all.
This part of the information, with the assistance of a large number of researchers, is combined with the part collected by no one to effectively summarize the situation at the mission site.
The diameter of the target celestial body is about 600 kilometers. It is not directly illuminated by the star's light and is almost pitch black without turning on the lights.
The reason why it is just almost is because the stars in the starry sky are brighter in an environment without an atmosphere, and the position of the target point should be the relay point between the two stars, so it can be seen visually that two stars are particularly bright. . The sky is full of stars, and the target star has a very faint light outline.
The teleportation gate is on the opposite side, actually on orbit, five hundred meters away from the ground.
Five hundred meters in the atmosphere is a very far distance for lighting equipment, but at the scene, it can illuminate a large area, enough for astronauts to receive some terrain information.
Chemical and material experts transferred from various companies judged from the information given by the astronauts that the main thing on the ground that would affect operations was nitrogen ice.
In fact, under current industrial conditions, no one has actually seen nitrogen ice. However, the ice area observed on site is large, and nitrogen ice can be distinguished from it.
In a basic environment of about two hundred degrees below zero, most non-solid substances at room temperature that can be left behind by gravity will freeze into a solid state. Among them, substances that are gaseous at room temperature have lower boiling points and smaller specific heat capacities, and are affected by events such as small meteorite impacts. , will volatilize more and faster into gases. After cooling down again, these gases will freeze more slowly than water. Without air pressure, rain will not form, but snow will fall directly. Therefore, the ice and snow formed by the gases will be located above the terrain. The distribution is more dense in areas with higher altitudes.
These areas dominated by nitrogen ice need to be avoided in subsequent missions to avoid trouble and danger caused by small-scale gasification.
Data analysis is still being done here, and the astronauts have been preparing for the second operation after taking a half-day rest.
Both astronauts have to go there.
The first goal is to test the endurance of the space suit a little bit. The test is not an extreme test. The safety of the astronauts is the highest priority in everything.
Under this premise, astronauts also need to do some orbital tests, such as which direction to push things horizontally to fall to the ground, and calculate local gravity acceleration, orbital speed and other parameters.
In order to cooperate with the mission, the two astronauts each had to carry an extra piece of equipment of about 20 kilograms before departure. They were both magic lighting devices, one with focus and one without. These two devices themselves are also specially made and can collect the value of the natural magic level, that is, whether the magic device can be charged naturally.
People outside are not idle either. In addition to the analysis department, the space suit team has also gathered some people to study whether there is a better space suit power solution.
The new power plan has no impact on the opening of the door, but if it does not move, there is still a problem. Now that the existing power has been slightly adjusted, whether it can resist the gravity of the site, and whether the endurance is enough to return to the portal, this is related to the astronauts. The question of whether you can come back after reaching the ground.
As the analysis department analyzes more and more situations, the dynamics are actually not optimistic enough.
The problem here is not the fault of the spacesuit team, because the "vector generation" power source is in charge of the Power Research Institute of the Academy of Sciences. When the new fighter project is launched, the engine set of Blue Sky Heavy Industry will also be integrated into the research institute.
Whether it is the Power Research Institute or the Space Suit Team, they are all blind when it comes to outer space exploration. They rely heavily on the command organization led by Wang Qi. It is normal for some things to be insufficient.
Spacesuits and astronaut endurance tests, this project took up most of the time before the first opening.
After that, the astronauts rested for five days, and the spacesuits entered the refit stage two days in advance.
Because of the tight schedule and heavy tasks, many things could not be taken into consideration, and the weight of the space suit also soared from 145 kg to 161 kg.
After adjusting the continuous propulsion capability of the space suit, it is necessary to conduct ground testing.
As mentioned before, heat loss in a vacuum environment mainly comes from infrared heat radiation, but for ground tasks, there is an extra contact surface of the sole of the foot, causing heat conduction problems.
On a completely solid surface, the contact area between the hard sole and the ground will not be too large, and it will not even account for 15% of the foot surface. However, if we extend the time scale, will the surface change due to heating, and what is the insulation effect of the sole? , whether it will have an impact on the environment inside the spacesuit needs to be concluded in order to facilitate the subsequent formulation of actual tasks.
The shoe problem is a minor problem. After all, there is a propulsion backpack, which does not require astronauts to perform complicated walking work. Therefore, the shoes can sacrifice mobility to obtain more insulation capabilities. The real difficulty lies in the fixation of foreign objects and gloves.
The objects that the mission plans to put on site must be normal-temperature items here in the exile. Even if they are frozen in advance, if they are taken out and allowed to be held by the astronauts hanging on the rack for a while to blow the air, the temperature will not be too low. In other words, the mission When the props are used on site, there is at least a temperature difference of more than 100 degrees from the local environment. What will happen if these things come into contact with the ground or even are implanted into the ground, work must be done in advance.
It is impossible for gloves to be completely insulated. Let alone the current materials, it will not be possible in another hundred years. What can be done is to add a thermal management layer on the palm surface to keep the hands warm, but this will also increase the environmental impact. Thermal risk.
The significance of ground testing is to master the minimum power data of the thermal management layer to reduce environmental impact without affecting the astronauts' movements as much as possible.
It was more cautious to go to the ground for the first time. The two pilots went on the mission together and brought a set of thousands of meters of steel wire. One person went to the ground and the other stayed near the portal to avoid accidents.
The reason why the wire rope must be made thousands of meters long is to give the astronauts some reaction time, because the situation on site is complicated and there are many risks when two people fly together.
Fortunately, enough preparation work was done. Except for some time management problems, the mission went smoothly overall. The two astronauts successfully collected samples from the ground and returned.
There is no problem with the previous analysis. The surface is mainly composed of water ice and nitrogen ice. No rock formations were found at the first landing point. The possibility that the entire target is an ice ball should be considered.
After confirming that the temporary improved power can support the movement from the ground to the portal, after discussion, it was found that the preparation time for the follow-up work is relatively long, and there is no way to work overtime to complete it. We simply ended this stage of testing and began to customize a formal action plan.
Wang Qi called Solaris to close the door and asked about opening the door.
