[Canon, begin to adjust the direction of flight, target Mars, the fourth planet of the solar system.] ］

[Roger, adjusting.] ］

[After adjustment, you can go.] ］

[Start the photon engine and start accelerating.] ］

Fang Tianbo immediately pressed the start switch of the photon engine, and suddenly one of the Jinwu 3 nuclear fusion reactors of the spacecraft began to supply surging energy to the photon engine.

Due to the scarcity of material in outer space, the beta rays from the photonic engine vent are not observable to the naked eye, although they gush out.

Propelled by a photonic engine, the Sun-By-Day began to accelerate evenly towards Mars.

The front half of the ship is half-wrapped in a condensed matter shield, and as time goes on, the speed of the ship gets faster and faster.

[Report, impact phenomenon.] ］

[Note the bearing and distance.] ］

[Roger.] ］

The so-called impact phenomenon is actually a common problem of sub-light spacecraft, because the spacecraft is very fast, it will produce a violent impact phenomenon when it touches any matter, even thin interstellar dust will produce a huge impact force.

This is also a very troublesome problem when sub-light spacecraft fly inside the star system.

If the Sunrise is not protected by a condensed matter shield, the hydrogen or helium atoms in these interstellar dust will constantly wash away the spacecraft; If you encounter a small meteorite the size of a screw, it can cause a tragic destruction of a spaceship ship in an instant.

The Anluo people use high-power magnetic field deflection pairs to avoid impacts, and it is not known how other civilizations solve this problem.

……

"How is that possible?" Dr. Archimedes' eyes widened as he looked at the satellite surveillance information in front of him.

The others also couldn't believe it, they were monitoring the situation of the new Chang'an space station just now, especially the huge spacecraft of the Chase Day, which was their focus on the target.

Ten minutes ago, the Chronicle began to leave the berthing area of the new Chang'an space station, and NASA satellites immediately monitored the relevant information.

At first, the ship was flying slowly and decently into the outer orbit, until they encountered something like hell just now.

"Go ahead and test again." Archimedes calmed down and commanded.

“OK。”

A group of staff operated the satellite's instruments and equipment, and continued to track the spacecraft, but the more they tracked, the more frightened they became.

It's too fast, and it's getting faster and faster.

"Oh buy karma! It has reached a speed of 300 kilometers per second, equivalent to a thousandth of the speed of light, and it continues to accelerate. ”

"......" Dr. Archimedes looked at the real-time data in front of him, and couldn't calm down for a long time, when suddenly a hand patted him on the shoulder.

"Archimedes, what's wrong?" NASA's new administrator John ?? Burns asked as he appeared behind him.

"Administrator John, we were monitoring the Human Innovation Alliance's spacecraft just now......" Dr. Archimedes quickly explained the situation.

"Are you sure?" John?? Burns' first instinct was not to believe it.

Archimedes pointed to the surveillance database and the people present and said, "Sir, there is no need for me to make such an international joke. ”

Despite being an administrator, as the administrator of NASA, he still has some academic qualities, especially in aerospace. Burns hurriedly and carefully reviewed the monitoring database, and then looked at the current real-time monitoring results.

"The speed has now reached 32,000 kilometers per second, which is already more than one-tenth of the speed of light." A staff member exclaimed.

Dr. Archimedes felt his worldview take a hit, and John?? Burns was no better, sitting in his chair with cold hands and feet, staring blankly at the tumbling data on the old-fashioned screen.

［33723KM/S…… 33815KM/S…… ］

"Judging by the trajectory of their spacecraft, they are heading to Mars." Dr. Archimedes said with some dismay.

"At the speed of their spacecraft, how long will it take to reach Mars?" John?? Burns asked weakly.

Archimedes thought for a while and replied: "The last Mars opposition has just passed, and the distance between Mars and Blue Star is relatively close at present, with the speed of their spacecraft, it will take about two hours!" ”

At present, the distance between Blue Star and Mars is relatively close, and the distance between the two sides is about 141 million kilometers, why is the distance between Blue Star and Mars relatively close? In fact, this has something to do with the fact that the orbit of Mars has been at opposition to the Sun.

What is Mars opposition?

Mars opposition means that Mars, the blue star and the Sun are almost in a line, and the blue star is located between the Sun and Mars, when the side of Mars illuminated by the Sun is completely facing the blue star, so it is bright and easy to observe.

Mars is spaced about 779 days apart by two adjacent oppositions, with an average of one opposition in 780 days, with the most recent occurring on July 27, 2018 and October 6, 2020.

During the Mars opposition, it is the closest time between the blue star and Mars, which is also the time period when space agencies of various countries have launched Mars probes in the past.

However, there is also a distinction between Mars oppositions and Martian oppositions, which are divided into Martian oppositions and Martian oppositions. The great opposition is that Mars, the blue star, and the sun are not only on the same line, but the blue star is near the aphelion, and Mars is near the perihelion, which is the so-called Martian opposition.

Mars at opposition is within about 60 million kilometers of the closest to the blue star and can reach a maximum of more than 100 million kilometers. Due to the eccentricity of Mars' orbit of nearly 1/10, it is 206.7 million kilometers from the Sun at perihelion and 249.2 million kilometers from the Sun at aphelion, a difference of 42.5 million kilometers.

For example, on the opposition of Mars on August 27, 2003, the distance between Mars and Blue Star reached the shortest distance in 60,000 years, only about 55.758 million kilometers.

The opposition of Mars on July 27, 2018 is a great opposition, while the opposition of Mars on October 6, 2020 is a minor opposition, which means that the closest distance is about 100 million kilometers.

As the speed of the spacecraft became faster and faster, it was already very difficult to monitor and search on the ground, and it was only possible to carefully monitor and search along the trajectory.

Kaohsiung Space Center.

"The Sun-Ticker has reached a really large cruising speed, 41,427 kilometers per second."

"It is expected to reach the Mars synchronous orbit in 4,197 seconds, and the whole journey is expected to take 6,273 seconds."

"The ship has been restored, everything is normal."

“……”

Listening to the methodical report of the staff, Wang Tu temporarily put his mind at ease, the danger of sub-light speed flight is very great, not only is it difficult to control on the ground, but the relative speed between the high-speed flying spacecraft and other things in space is very large, if there is no condensed matter shield, just the magnetic field deflection, the danger is still very great.

……

[Captain, the ship has reached the deceleration zone.] ］

[Immediate braking and deceleration.] ］

[Yes.] ］

With 15 million kilometers to go from the geosynchronous orbit of Mars, the Sunrise began to brake and decelerate, and if it did not brake now, the Sunrise would directly cross the solar orbit of Mars and then rush towards the asteroid belt and the orbit of Jupiter.

After all, at such a fast speed, the gravitational pull of Mars, which is only 2/5 of the blue star, is not enough to capture the Sun, so braking and slowing down is a must.

[Yuri, report on the ship's fuel reserves.] ］

[It is reported that the current day-by-day number of ionic working fluid is 108.76 tons, and the nuclear fuel is 4316 kilograms]

Fang Tianbo didn't have much worry about fuel, after all, the ionic working fluid was submetallic hydrogen, which could be used as nuclear fuel

Even if all this fuel is consumed, the spacecraft can use 2,000 tons of cargo as nuclear fuel, and the daily ship can also capture asteroids and the like to replenish nuclear fuel.
