The countdown sound continues: "Countdown to 1 minute and 11 seconds..."
The sound of the engine was already a little too low to be heard, and there was already a light feeling under my feet, as the engine was about to shut down. Now, the speed of the spacecraft has reached a speed of 1010 kilometers per second.
Space is so vast. As long as you have the courage 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. These changes cannot be 100% analyzed by modern physics. All we know is that by this time, the mass of the material will begin to increase dramatically, enough to overwhelm the engine.
However, at low speeds, that is, less than one-tenth of the speed of light, there is no need to consider it for the time being.
"Countdown: 10 seconds, 9 seconds..."
At this time, the thrust is almost imperceptible. To be more precise, the engine is in the process of cooling itself. If such a huge engine is cooled rapidly, the engine will be subject to great stress at a temperature of only 3K in space. The occurrence of cracks is not even ruled out.
Space is so dangerous that everyone has to be careful.
"3, 2, 1, 0, stop!"
In an instant, everyone was completely floating, and all acceleration completely disappeared.
"Everyone, we have now reached a speed of 1010 kilometers per second. From now on, we will maintain this speed and go straight forward (there will be a slight bend due to the gravity of the sun). 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. It will travel about 100 million kilometers from now and arrive in 12 days.
Now, everyone has 12 days of free time, and you can carry out your own research projects. Good luck to everyone! ”
Liu Haibo's words announced the real beginning of various research in space this time!
Physical scientist Zhang Jianye was the first to take action. After reporting his actions to Liu Haibo, he started taking action. Although the captain of Zhang Jianye's team is Lin Yun, during the research, the scientist is the real captain.
"Start the scanning equipment and search for surrounding asteroids." Zhang Jianye of the third team looked serious. Although no asteroids were encountered during the flight, that 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 space is so large, the distance between asteroids is actually very large. Sometimes, you are on this asteroid and cannot see the nearest asteroid with your naked eyes.
"Beep beep..." The electronic instrument started working. It uses advanced scanning equipment superimposed on infrared scanning, x-ray scanning, gamma ray scanning, visible light scanning and other technologies. It can detect fragments one centimeter in size 100 million kilometers away. All theoretical objects with a temperature above 3k.
Such a scanning instrument, which is also an electronic telescope, costs more than 300 million yuan.
"Dudu..." different voices came. This is a sign of an asteroid discovery.
The electronic voice automatically reported: "An asteroid has been discovered and a three-dimensional image is being generated. The diameter of the asteroid is 15 meters at its largest and 12 meters at its smallest. The surface temperature is minus 110.42 degrees Celsius and it is solid. The speed is 33.65 kilometers per second. It is 120,000 kilometers away from the spacecraft. It has an estimated mass. tons. Spectral color phase element analysis shows that the surface material composition is: silicon element 24.3%, oxygen element 32.8%, hydrogen element 16.5%, iron element 20.4%, carbon element 4.2%, chlorine element... sodium element... nitrogen element... …”
Each element has its own unique light color after being illuminated by light. This is the origin of spectral analysis. Now, current electronic instruments 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 him, team leader Lin Yun was a little surprised. Everyone has received the most extensive basic training before entering space. The temperature of space dust is generally around minus 260 degrees Celsius; absolute zero is minus 273.15 degrees, and the cosmic microwave radiation background temperature is around minus 270 degrees, which is said to be the temperature left over from the Big Bang - the current scientific theory.
"It's normal." Zhang Jianye didn't look back and was immersed in his work. "It's close to the sun here and can get direct sunlight. It's not unusual for the temperature to rise above zero. Minus 110 degrees is actually a relatively low temperature."
"Oh, haha, I haven't looked at the sun for a long time. I accidentally forgot about it!" Lin Yun smiled sheepishly.
"Then be careful one day the sun forgets you. Ha... Captain, I have to trouble you to catch this little thing."
"Okay. There should be no problem. But more than 3,100 tons is no small thing, it is a behemoth!" Lin Yun smiled, turned around and left.
If you want 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 eliminating those aircraft with a thrust of less than 200 tons and all old-fashioned engines. , will only be used as a space steering device; in addition, it will be sold to foreign countries in exchange for a large amount of mineral resources; in fact, even the old 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 devaluation of paper currency, mineral resources are the actual currency. However, Lin Yun seems to have heard that his boss is considering producing smaller engines to produce civilian space shuttles and sell small space shuttles to ordinary people.
Ten minutes later, Lin Yun, who was dressed and had undergone strict inspection, and his deputy Wang Sheng stepped out of the spaceship. The two used electromagnet technology at their feet to stick to the surface of the spacecraft, and slowly walked along the gap of the space shuttle to the space shuttle group described by their group. There are 40 space shuttles, and each team of explorers is assigned 4 aircraft, two Dreams with a thrust of 480 tons, and two Adventures with a thrust of more than 480 tons. In fact, the Explorer is a variant of the Dream, except that it has more seats and can carry more team members; it is convenient for space exploration.
Opening the door of the space shuttle, Lin Yun and Wang Sheng entered the space shuttle together and began to apply for takeoff. Catching asteroids in space is still relatively dangerous, so it would be safer if two people work together.
"Report to the General Controller: Space Shuttle 301 of the Third Team applied for takeoff."
"Received, wait a moment...Okay, now the countdown starts: 10, 9..."
Click... In the sky, the steel manipulator clamping the landing gear of the Dream aircraft slowly opened, and the Dream slowly retracted the landing gear. A slight electromagnetic force was emitted, slowly pushing the Dream away from the spacecraft.
The plane slowly fell off, but could not ignite immediately; it was not until it was 200 meters away from the spacecraft that it looked at the direction and gently ignited it. 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 car crash.
Light blue flames spurted out, and the plane suddenly took off with acceleration exceeding 30 times gravity. Amidst the crash, Lin Yun and his deputy pressed hard against the backrest, making it difficult to move their whole bodies.
"It's great! I haven't experienced this feeling for a long time!" Lin Yun let out a ghostly cry. Lying in a small spaceship for just a few days was already unbearable for the proud pilots of these expert companies. Passion and speed are what these people yearn for!
