Chapter 495 (1/2)
Time goes by slowly, and the time of the day passes quickly
Navy support fleet.
The commanders of the first and second fleet were discussing the tactical arrangements and contingency measures after arriving at the wormhole battlefield. At the same time, they received a message from the communication officer.
”Sir, commander ISAR is calling for us to pay close attention to the rear!”
”Behind you?” Both were stunned.
Soon afterwards, they actually caught an abnormal target from the gravitational radar.
”Sir, an unknown celestial body has been found in the rear of the fleet. It is 68 million kilometers away and of great mass. It is coming towards us at an amazing speed. It is expected that it will contact our fleet in 10 hours!”
Unknown objects? Everyone looked suspiciously at the sudden signal on the radar.
”Is it a wandering celestial body?”
”It should not be. We have established a complete monitoring system for the movement of celestial bodies in the adjacent galaxies. There should be no celestial bodies in this position! What's more, the celestial bodies with this speed and mass belong to the third level dangerous sources, which can't be ignored by us! ”
Since it is not a wandering celestial body, then There seems to be only one truth left!
There was an incredible flash in the eyes of both divisional commanders
An hour later, the fleet's optical radar finally captured the target image, which was displayed in front of the public Big green umbrella?!
Tens of thousands of square kilometers of green umbrella cover the target behind all optical information, so that they can not see the full picture of the target.
”Is that it?”
”Although the image has changed, but It can only be it
The faces of both commanders were dignified.
The biological fortress I really catch up with you?!
After the ultimate gravitational acceleration of the stars, the immortals have gained considerable speed. In addition to the original high-power thrusters, Nie Yun also provides an additional thrust for the immortals.
If the mariner fleet can observe the back of the canopy, it will be found that the leaves of the immortal have been coated with a layer of bright silver, which reflects the light of stars behind, adding a bit of fantastic color to the elders.
This kind of coating is only one layer of mechanical insect total reflection film, so the cost of mechanical insect material is negligible, but it has produced a ”super solar sail”!
Light is a kind of photon with momentum but no static mass. When the photon hits the smooth plane, it can change the direction of motion like a ping-pong ball rebounding from the wall, and give the impact object corresponding force. This is the design principle of solar sail.
The famous astronomer Kepler put forward the hypothesis of solar sail 400 years ago.
The closer you are to the star, the more powerful the solar sail will be!
In fact, the ”Torch” series of energy acquisition devices in the orbit of the sun and stars in the Prometheus plan use the powerful thrust of photons to counter the huge gravity of the stars, thus maintaining their stable low orbit operation.
The thrust produced by a single photon is extremely small, but when the area of the solar sail is large enough and the reflection effect of the coating is super strong, the solar sail can make the flying objects get continuous powerful power in the space without resistance!
For captain Nie, who preferred to sail design, it was a kind of non working medium propulsion mode without any cost. It provided an additional 10% acceleration for the elderly, so that he could catch up with the latter in a short period of time and catch up with the latter before the two marine fleets joined.
And this, of course, is far beyond ISAR's expectations.
According to her original plan, the navy fleet was to mark the wormhole of the solar system, and set up her own hands to solve the biological fortress and eliminate the unstable factors.
But now, looking at the situation in neighboring galaxies, the first and second fleet of the Marines are on their way to the wormhole battlefield for support. Behind them, they are the eternal survivors who are constantly chasing after.
After the immortal, they are the first and second fleet of the Yuzu.
The three are chasing each other on the same channel, and they all want to strive for strategic initiative. All the mobile forces have formed a straight pursuit chain
