The Orient Express began to fly around the moon. The only thing Bei Haiyang had to do was to control the aircraft to keep it in a position where the sun was slanting.
There is no atmosphere on the moon, and the moon's surface is directly exposed to space. Therefore, the temperature of the moon's surface changes very drastically. When it is the hottest during the day, the lunar surface temperature can reach 127°C; when it is the coldest at night, the temperature can drop to minus 183°C.
Sudden cold and sudden heat can be balanced by protective covers for new human superpowers, but it is very dangerous for huge aircrafts; in theory, modified aircraft are equipped with internal constant temperature systems that can withstand such large temperature differences.
, but there is a question mark as to whether the millions of components inside the aircraft can withstand a temperature difference of more than 3 hundred degrees?
He is also considered a senior pilot. He is very aware of the possible dangers of the aircraft returning to the atmosphere. The more he knows, the more afraid he becomes. The reason why he always stays in the position where the sun is slanting is to obtain a relatively stable temperature environment. He has set it for himself.
A target is between plus and minus 50 degrees.
It’s not that you absolutely can’t, but you should try to avoid frequent trips in and out of areas with large temperature differences.
Orient Express 01 became a plane that avoided the sun. As the moon rotated and orbited the earth, it always kept itself on the dusk line where the sun was about to set.
At any place on the moon, the length of day is approximately equivalent to 14 days on Earth, and the length of night is approximately equivalent to 14 days on Earth.
Due to the dense atmosphere on the earth, sunlight will be scattered and refracted when passing through the atmosphere, so the sky will still be bright after the sun sets in the evening and will not get dark quickly; in the early morning, the sky will be bright before the sun rises.
, then the sun rises and the sky is bright.
The moon's day and night changes are different. Since the moon has no atmosphere, the moon's day and night change rapidly. Once the sun "sets", the moon will instantly become dark; once the sun rises, the moon will instantly show a patch of sunlight.
The junction of darkness and light is the dusk line. Well, it may be more appropriate to describe it as a black and white line. But the dusk line is constantly moving and not fixed; so when a person stands still in one position, the surrounding environment
The temperature either increased or decreased, experiencing peak changes from minus 183 degrees to as high as 127 degrees over the course of 14 days.
Why must the space roaming time be set within 20 days? This is the reason. When the plane puts the passengers out of the cabin on the moon, the timing starts! A cycle of 14 days, and when it returns to the dusk line again, it is the time to board the plane again.
During these 14 days, the space passenger plane will not come to pick them up, because they may be in high temperatures of up to 100 degrees, or in low temperatures of minus 100 degrees. Such a complex environment is far from being called a modification of a space shuttle.
It's very dangerous for passenger planes.
The essence is that humans use ordinary civil aviation airliners to modify them to complete the mission of the space shuttle. This itself is a temporary solution.
Such a modified aircraft has its own constant temperature system, which can keep the body parts stable. The aircraft is not afraid of overcooling. The ambient temperature of space is already below minus 2 degrees, but it is very afraid of changes in overcooling and overheating, which will affect the constant temperature of the aircraft.
The system puts heavy pressure on the system, and accidents often occur as a result.
Many similar accidents have occurred in previous space flights, so for the pilots, they would rather fly the plane to pursue a constant temperature than go to the moon and let the body test the plane back and forth in a temperature difference of nearly 300 degrees.
thermostatic adjustment.
It is best to fly around the dusk line, because the temperature here is closest to the body temperature, which can minimize the output of the aircraft's thermostat system and save the most fuel.
The ground was getting closer and closer, and there was no designated place as to where it would land. Anyway, it was the circle around the dusk line, but Bei Haiyang still hoped to find a high ground where it would be easy to put people in and out, and conducive to the spread of signals.
Space flight is not as simple as imagined. Once entering space, countless problems arise. If they were not new human superpowers who can handle many problems on their own, just leaving the spacecraft would consume countless energy.
Bei Haiyang is looking for a relatively suitable hovering position. He is looking for a brighter place, not a shadow.
When you observe the moon through a telescope, you will clearly see the distinctive features of the moon's surface: some areas are bright, some are dark, and large and small bright and dark areas are staggered all over the moon's surface.
As early as hundreds of years ago, people had observed this feature of the moon's surface through telescopes. At that time, people thought that the large dark areas were the seas and oceans on the moon; the small dark areas were regarded as the seas and oceans on the moon.
The lake and bay were named after them.
These names are still used today. Later, people learned that the oceans and lakes on the moon are completely different from those on the earth, and there is not even a drop of water there.
The dark areas on the moon (the so-called seas, oceans, lakes, and bays) are actually plains and lowlands of different sizes; because those places are widely distributed with relatively young rocks formed by lava flows, and are relatively low-lying, they are
The reflectivity of sunlight is low and appears dark black compared to the surrounding area.
The bright areas on the lunar surface are plateaus and mountains on the moon; their composition is mainly relatively old rocks, which have strong reflection capabilities for sunlight and appear very bright in comparison.
Craters are widely distributed, which are the most prominent features on the moon's surface. They are also called craters, which were created by meteorites.
The altitude of Orient Express 01 is getting lower and lower, and the speed is getting slower and slower. He tries to find a relatively high place with flatter terrain.
Lunar craters are approximately circular, very similar to the terrain of volcanic craters on Earth. In the middle of the crater, the terrain is low and flat, and some are dotted with small peaks; the inner side of the crater is steeper, and the outer side is gentler. Some craters are surrounded by mountains.
Many bright streaks radiate outward.
Most of the craters on the moon are named after famous astronomers, such as Copernicus, Kepler, Newton, Plato, Tycho, Zu Chongzhi, Zhang Heng and other craters, but his knowledge is limited and he has no time to identify them.
These things all look the same to him.
He finally found a flat highland, which was rare on the pockmarked moon surface. It had been two days since he left the earth, and it was time to land.
"East Pacific Aviation Control, this is Orient Express 01. The landing point has been found. The system check is normal. Please open the cabin."
After a period of delay, the answer from the ground was, "Good guy, Orient Express 01, if you go a little further, you should go to the back of the moon! I agree to the application for opening the cabin, everything is based on your own judgment."
