Earth Invasion

Chapter 5 Bustling Journey
Going on a spaceship in this year is similar to going on an airplane in earlier years, the difference is that you have to go through the airtight door twice, and you have to eliminate static electricity once.Although the standard cabins for space transportation now have enough safety measures, there is nothing wrong with being careful.For the sake of safety, the spacecraft does not breathe pure oxygen as it did hundreds of years ago, but has an air composition similar to the surface of the earth.Of course, when accelerating or braking, the spacecraft has pure oxygen to provide it, after all, it has to fight against high overload.Although fewer and fewer people have not undergone genetic enhancement over the years, the continuous acceleration of the spaceship still does not exceed 8 G.This is mainly for passenger comfort.

Zhang Mai and his classmates walked through the airtight door, wearing the fragrance of antistatic spray on their bodies.Several people looked at the boarding pass in their hands.Boys are basically on the right side of the standard passenger compartment, while girls are on the left.

This passenger spaceship is a standard towing spaceship plus a standard passenger cabin arrangement.In accordance with the "Baike** Global Freight and Passenger Transport System Standards", the global ** aerospace transportation industry has basically unified the specifications of tugboats and standard cabins.Tugboats and standard cabins for non-atmospheric space round-trips uniformly use hexagonal prisms.This kind of transportation arrangement derived from the structure of the honeycomb can easily allow an ordinary tugboat to gather six cargo holds on its six sides, and then form a huge cargo hold transportation array by analogy.On this array, more tugboats can be easily added to form a transport array with greater thrust.Its economic and capacity advantages are self-evident.

For the sake of safety, passenger ships generally have no more than 6 marshallings. In many cases, most tugboats only carry three passenger compartments during passenger transport tasks.The passenger spaceship chartered by Zhang Mai and his school only carried two standard cabins.

"74 kilometers, almost a whole day." Zhang Mai swiped his boarding pass on the compartment with the same number, and the airtight door of a standard four-person compartment opened.He pushed his suitcase against the metal railing of the doorway and let himself fly in the opposite direction, stuffing his suitcase into a separate locker.Space travel Remember to secure all heavy objects, this is a basic boat requirement.

There are four independent cabinets and four shelters in the standard quadruple room.The shelter provides individual services such as lighting, air conditioning, drinking water and multimedia.After all, on a space voyage, you don't know who you're going to share a compartment with, whether it's a male or a female passenger.Independent cabins provide a private space.This kind of humanized service is not pleasant at all in the eyes of these students. Do you just stay in your cabin and count sheep during such a long journey?The best way to spend a boring journey is of course to speak loudly.

Zhang Mai put away his luggage, opened his shelter and took a look.Old Ke also floated in after him.His suitcase was opened for some reason, and he was frantically grabbing the clothes and other things flying around and stuffing them into the cabinet.

"I said, Old Ke, where are you going to practice next semester?" Zhang Mai intercepted a flying boxing glove, and then pushed it towards Old Ke.

"I haven't thought about it, I guess I should find a company with a Chinese prefix." Old Ke stuffed the last sundry into the cabinet and locked it.At this time, there was a slight vibration from the spaceship—after boarding, the control system of the central airport disconnected the restraint arm that had been jamming the spaceship.

Three harbor workboats approached.In the boarding area, the starship is not allowed to activate the main reactor and light up the propulsion array.It needs to be pushed to the sailing area by those working boats in the port that use compressed air as power.Then the spacecraft will enter the host startup phase

The spaceship entered the starting position, and the spherical unmanned aerial vehicle used as a path guide in the starting area flashed red light to form an indicating channel at a distance of 5000 meters from the starting area to the satellite. After the final inspection procedures with the spacecraft at the port were completed.The tower issued a release command to the spacecraft.

"L4E95735, this is the control tower, the flight command is issued, start the main engine, I wish you a pleasant journey."

"L4E95735 understands! The superconducting battery stack is connected to the main starting path. The proton beam is introduced, and the core temperature of the subcritical reactor rises to reach the critical temperature. Liquid lithium is injected into the first circuit, and the plasma is extracted!"

"Activate the main propulsion! L4E957355.00% thrust! Departure!"

The spaceship started smoothly, Zhang Mai and the others felt nothing in the cabin, and the real-time picture of the spaceship starting was playing in the cabin.No one was walking around, and everyone knew that the spacecraft was flying away from the satellite and not entering the real acceleration phase.Only after the acceleration phase is over and the real cruising state is entered, can you go out and walk around.It is estimated that soon, the flight attendants will come to ask the passengers to fix themselves in their cabins.

"Dear passengers, welcome to China Eastern Airlines flight L4E95735. I am the chief purser of this flight. On behalf of all the flight crew, I wish all passengers a pleasant journey. Now the spacecraft is about to enter the acceleration phase. Please follow the instructions of the flight attendants Fix yourself in the cabin, and let your chest, abdomen or back face the direction of the acceleration of the spaceship. Doing this can better resist the G value generated by the acceleration, thank you for your cooperation. Please, passengers..."

In the purser's voice containing three plus signs, the flight attendants in navy-colored uniforms began to inspect each cabin and helped the passengers fix themselves.After going through a pull-net inspection.A sonorous male voice appeared on the radio again.

"Passengers, the spacecraft is about to enter the acceleration state. The estimated acceleration time is 37 minutes. The cruise speed of the spacecraft is 10 kilometers per second. Before the acceleration is completed, please do not release yourself from the fixed cabin. Release to avoid danger. Thank you for your cooperation."

After two broadcasts, Zhang Mai, who fixed himself on the bulkhead, obviously felt a sense of acceleration.Now his back is facing the accelerating direction of the spaceship, and he feels his back pressing against the bulkhead.On the other hand, Lao Ke, who was opposite him, had a constipated expression on his face. It is estimated that this guy felt an obvious push back.

Passenger ships are not cargo ships.Those cargo spacecraft traveling to and from the La Langue point and the synchronous orbit spaceport and the near-low orbit space station basically never consider the discomfort caused by linear acceleration and angular acceleration.As long as the spacecraft controllers wrapped in liquid anti-G suits feel okay, the faster the speed and the shorter the orbit, the better.But passenger spaceships cannot use the shortest straight line between two points.After leaving the Larangu point, most of the spaceships will accelerate along the direction of the earth's rotation, that is, the direction of the moon's flight, from 4 kilometers per second to the slower speed of the second universe.Then the orbit is transferred to the ground, which is basically a huge arc.In this way, although the flight distance is greatly increased, it is more comfortable.
