Homo sapiens.

Suez area.

Harij Oasis District, Harij Space City.

On 10 tracks with a width of 6 meters, a giant is moving slowly.

Dr. Mikoyan looked at the behemoth in front of him, and felt a sense of joy in his heart. This is the super space shuttle he worked so hard to develop—La.

The full load reaches 3.2 tons, the payload is 1.5 tons, the body weight is 9600 tons, and the special fuel is 7400 tons.

This is one of the wildest spacecraft ever.

Dr. Mikoyan picked up the walkie-talkie: "Sit, the space shuttle is about to arrive at the refueling station."

"Got it, doctor."

La - The space shuttle has a very strange shape, somewhat similar to Lucia's Blizzard space shuttle, its body itself is an aircraft, and the payload is on its back.

From the outside, it looks like two space shuttles stacked on top of each other, and the upper spacecraft is slightly smaller than the space shuttle La.

7 minute later.

The space shuttle entered the feeding station, which is also the processing plant responsible for the production and processing of submetallic hydrogen particles, but the processing plant is hidden deep underground.

Liquid oxygen has been injected into the space shuttle's liquid oxygen storage tanks.

The injection of submetallic hydrogen particles is not as simple as liquid oxygen.

In order to ensure safety, the temperature must be maintained at minus 180 degrees Celsius throughout the process to ensure the stability of submetallic hydrogen particles.

The super cooling system inside the space shuttle has obtained the surging power of the nuclear battery and is running at full capacity.

In order to prevent submetallic hydrogen particles from sticking together at low temperature, the surface of these submetallic hydrogen particles is coated with a film to ensure a smooth and non-sticking surface.

The container for storing submetallic hydrogen is also specially designed. The interior of the entire container is composed of many pipelines. Electromagnetic acceleration guide rails and magnetic attraction devices are embedded in these pipelines. Submetallic hydrogen is filled in these pipelines.

The reason for this design is very simple.

Because submetallic hydrogen is a superconductor, it is easy to accelerate electromagnetically and let it be ejected. If other ejection methods are used, the efficiency, reliability, and adjustability are not as good as electromagnetic ejection.

After one and a half hours of filling, all the submetallic hydrogen particles were finally stuffed into the storage tube.

Dr. Mikoyan immediately picked up the walkie-talkie: "All departments will conduct a final inspection immediately."

"receive."

In fact, this kind of inspection is very fast, because the interior of the space shuttle La is densely covered with a large number of biological sensors. Once an abnormality occurs, it will basically not be missed.

In less than 10 minutes, the inspection was complete.

"Report, everything in the cryogenic containment system is normal."

Dr. Mikoyan took a deep breath. He knew that it must be launched as soon as possible. Even because of the existence of the ultra-low temperature containment system, submetallic hydrogen cannot be preserved for more than 300 hours, so it must be resolved quickly.

He immediately ordered: "Launch immediately."

"Received, start the launch procedure."

"Warning! Personnel within 1 kilometer of the space shuttle, please enter the exclusive bunker immediately."

"The runway is confirmed to be ready for takeoff."

"Clear weather with no major cloud cover."

"A launch permit has been obtained from the Space Division..."

Soon.

The space shuttle enters the runway.

This is a slanted runway with a slightly upward angle, and the direction of the runway is east by south, which is to take advantage of the angular velocity of the earth.

In addition, there are 6 guide rails on the runway. These guide rails are maglev super-heavy guide rails and also electromagnetic catapults. The purpose is to keep the space shuttle from contacting the ground and reduce the friction caused by contact with the ground.

"Space Shuttle reaches electromagnetic acceleration region."

"Maglev system activated..."

"Electromagnetic acceleration push plate connected to space shuttle..."

The space shuttle La, which was less than one centimeter up, floated up slightly, and the six specially designed electromagnetic acceleration thrusters at the back had been stuck on the landing gear of the space shuttle.

"The electromagnetic acceleration system is activated..."

The huge nuclear power of the base is quickly injected into the electromagnetic accelerator.

Driven by 6 ultra-large electromagnetic accelerators and in a state of magnetic levitation, the space shuttle Ra soon sped up on the runway.

This 12-kilometer-long electromagnetic acceleration guideway will increase the take-off speed of the space shuttle to about 1.5 kilometers per second, which is about 4 times the speed of sound.

And on the wings of the space shuttle, a large number of micro-wings have also begun to be fine-tuned in order to make full use of the air lift.

Although it is not as abnormal as the Phoenix Airliner and the Jinpeng transport aircraft, it can increase the lift by at least 11% to 13%.

The 12-kilometer rail is neither long nor short.

For the faster and faster space shuttle, it soon reached the end.

The space shuttle soars into the sky from a 33-degree slope.

At the moment of exiting the ramp, the shuttle's autopilot system ejected the first burst of metallohydrogen particles.

The explosion chamber has been heated to hundreds of degrees Celsius.

When submetallic hydrogen and liquid oxygen are injected, a chain reaction is triggered instantly.

boom!
In an instant, energy equivalent to 260 tons of TNT was released.

This explosion is not the end, however, but the beginning.

Boom boom boom...

A steady stream of submetallic hydrogen particles and liquid oxygen were injected into the four detonation engines.

The terrifying explosion shock wave made the space shuttle faster and faster, coupled with the adjustment of the lift direction of the wings, the space shuttle began to rush towards the Karman line at an angle of 48 degrees.

It took about 57 seconds for the space shuttle Ra to break through the Karman line.

This giant weighing more than 2 tons rushed out of the Karman line under the gaze of the whole world.

The space shuttle Ra did not separate from the space shuttle Solar on its back at this time, but continued to carry the space shuttle Solar.

It was not until the Homo sapiens space station reached the 1500-kilometer orbit that it was separated from the space shuttle Lieyang, and then the space shuttle La turned around and returned to Earth.

That's the scary thing about the super shuttle.

To be precise, submetallic hydrogen.

Without submetallic hydrogen as fuel, such a huge load cannot be pushed into outer space, let alone return to Earth by itself.

At this time, there are about 27.3% of the fuel left on the La, which is enough for it to slow down and brake by itself when it re-enters the atmosphere.

However, for this launch mission, the Space Business Department also arranged an additional space mission for the space shuttle Ra.

That is to go to the No. 3 space junk station in low-Earth orbit, and bring a batch of scrapped satellites and previously collected space junk back to Earth.

These obsolete satellites belong to Homo sapiens itself, as well as to forces such as Lucia, America, and the Europa Consortium.

For example, some of the hundreds of obsolete communication satellites of the Space Exploration Corporation were collected in one area by space recovery satellites, and then compressed into cubes.

Now the Ra space shuttle will bring these things back to Earth.

Although it is a scrapped satellite, there are many rare metals and radioactive substances inside, which must be properly disposed of.

Soon the space shuttle Ra arrived at Space Junk Station 3.

With the help of that large space junk recovery satellite, dozens of tons of space junk were stuffed into the built-in transport cabin, and fixed and counterweighted.

Then the space shuttle Ra started the engine again from a position of 420 kilometers in low-Earth orbit.

But this time when starting the engine, it is only a slight acceleration, and it does not need to be too fast. After all, this is re-entry into the atmosphere, and the earth's gravity and gravitational force will help accelerate.
