Half-immortal civilization

The countdown sound continued: "Countdown 1 minute 11 seconds..."

The sound of the engine was a little low and inaudible, and there was already a feeling of lightness under the feet, and the engine was about to shut down.Now, the speed of the spacecraft has reached 1010 kilometers per second.

Space is so vast, as long as you have the guts and enough energy, you can theoretically accelerate infinitely, up to 70% of the speed of light.As for exceeding 70% of the speed of light, some changes will occur, and these changes cannot be 100% analyzed by modern physics.All I know is that at this point, the mass of matter will start to increase so dramatically that it can overwhelm the engine.

But at low speeds, that is, less than one tenth of the speed of light, don't consider it for the time being.

"Countdown: 10 seconds, 9 seconds..."

At this time, the thrust is almost imperceptible, more precisely, the engine is in the process of cooling itself.If such a huge engine is cooled rapidly, at a temperature of only 3K in space, the engine will be subjected to great stress.Cracks are not even ruled out.

Space is too dangerous, everyone has to be careful.

"3, 2, 1, 0, stop!"

In an instant, everyone floated up completely, and all acceleration disappeared completely.

"Everyone, we have now reached a speed of 1010 kilometers per second. From now on, we will maintain this speed and move straight forward (slightly bent by the sun's gravity). According to the current direction, it is expected to be close to the summer solstice of the earth. The position corresponding to the sun point is inserted into the orbit of Mars. The journey from now on is about 12 million kilometers, and the estimated time is [-] days to arrive.

Now, everyone has 12 days of free time, and you can carry out your own research projects.Good luck everyone! "

Liu Haibo's words announced the real start of various researches in space this time!
Physical scientist Zhang Jianye first started to move.After reporting his actions to Liu Haibo, he started to act.Although the captain of Zhang Jianye's team is Lin Yun, the scientist is the real captain during the research.

"Start the scanning equipment and search for the surrounding asteroids." Zhang Jianye of the third team had a serious face. Although he did not encounter an asteroid during the flight, it was because the path had been calculated in advance.Although there are many asteroids or meteorite fragments in space, they are not large, and because the space is so large, the distance between asteroids is actually very large.There are times when you're on this asteroid and you can't even see the nearest asteroid with the naked eye.

"Didi..." The electronic equipment started to work, using advanced scanning equipment superimposed by infrared scanning, x-ray scanning, gamma-ray scanning, visible light scanning and other technologies, it can detect fragments the size of one centimeter from 3 million kilometers away, and can detect All theoretical objects with a temperature above [-]K.

Such a scanning instrument, which is also an electronic telescope, costs more than 3 million yuan.

"Beep..." came a different voice.This is a sign of the discovery of an asteroid.

Electronic voice automatic report: "Asteroid found, 15D image is being generated. Asteroid has a maximum diameter of 12 meters and a minimum of 110.42 meters; surface temperature minus 33.65 degrees Celsius, solid; speed 12 kilometers per second, distance from spacecraft 24.3 kilometers, estimated mass tons .Spectral color ii phase element analysis, the surface material composition is: 32.8% silicon, 16.5% oxygen, 20.4% hydrogen, 4.2% iron, [-]% carbon, chlorine...sodium...nitrogen... "

Each element has its own unique light color after being irradiated by light, which is the origin of spectral analysis.Now, the current electronic equipment can analyze the composition of material elements on the surface by scanning and analyzing the spectrum.

"Oh, minus 110.42 degrees Celsius? This is a high-temperature asteroid!" Next to it, the captain Lin Yun was a little surprised.Everyone gets the widest possible range of basic training before going into space.The temperature of space dust is generally around minus 260 degrees Celsius; while absolute zero is minus 273.15 degrees, and the background temperature of cosmic microwave radiation is around minus 270 degrees, which is said to be the temperature left over from the Big Bang—the current scientific theory.

"Normal," Zhang Jianye didn't look back, and buried himself in his work. "This place is close to the sun, and the sunlight can shine directly. It's not uncommon for the temperature to rise above zero. On the contrary, minus 110 degrees is a relatively low temperature."

"Oh, hehe, I haven't looked at the sun for a long time, and I accidentally forgot about the sun!" Lin Yun smiled a little embarrassedly.

"Then be careful that the sun will forget you one day. Ha...Captain, I will trouble you to catch this little thing back."

"Okay. There should be no problem. But more than 100 tons is not a small guy, it is a giant!" Lin Yun smiled, turned and left.

To drag such an asteroid, you must use the latest Dream aircraft. The improved Dream aircraft has a thrust of more than 480 tons. Now the master company is gradually phasing out those aircraft with a thrust below 200 tons. All old-fashioned engines , will only be used as a space steering gear; in addition, it will be sold to foreign countries in exchange for a large amount of mineral resources; in fact, even the old-fashioned engines sold to foreign countries are being discontinued.The modified new engine is more efficient, and has improved many minor problems-of course, such a good engine must be expensive.In addition, in today's society, with the depreciation of banknotes, mineral resources are the actual currency.However, Lin Yun seems to have heard that the boss is considering producing smaller engines for the production of civilian space shuttles; selling small space shuttles to ordinary people.

After 10 minutes, Lin Yun, who was dressed and passed a strict inspection, and his deputy Wang Sheng stepped out of the spaceship.Using electromagnet technology, the two people's feet stick to the surface of the spaceship, and slowly walk along the gap of the space shuttle to the group of space shuttles mentioned by their group. For 40 space shuttles, each team of explorers is assigned 4 planes, two Dreams with a thrust of 480 tons, and two Explorers with a thrust of more than 480 tons.In fact, the Explorer is a variant of the Dream, but with additional seats, it can carry more team members; it is convenient for space exploration.

Opening the door of the space shuttle, Lin Yun and another Wang Sheng entered the space shuttle together and began to apply for takeoff.It is still relatively dangerous to capture asteroids in space, and it is safer for two people to work together.

"Report to master control: Space Shuttle 301 of the third team applied for takeoff."

"Received, wait a moment...Okay, now start the countdown: 10, 9..."

Kaka... In the sky, the steel manipulator clamping the landing gear of the Dream aircraft slowly opened, and the Dream slowly retracted the landing gear, and a slight electromagnetic force was emitted, slowly pushing the Dream away from the spaceship.

The plane fell off slowly, but could not be ignited immediately; it was not until it was 200 meters away from the spacecraft that it saw the direction and lightly ignited.In space, because there is no interference of gravity, the influence of slight gravity is very obvious; if you are not careful, it is easy to cause a crash.

Light blue flames spewed out, and the plane took off suddenly with an acceleration of more than 30 times the gravity.Amidst the bang, Lin Yun and his deputy pressed hard against the backrest, making it difficult to move their whole bodies.

"Excellent! I haven't experienced this feeling for a long time!" Lin Yun let out a ghostly cry.Just a few days in a small spaceship is already unbearable for the proud pilots of these expert companies.

Passion and speed are what these people yearn for!
