Fictional travel to Alpha Centauri by using laser boosted solar sail

NASA's solar sail

In this text, I would think about fictional space trip to Alpha Centauri by using solar sails, what are boosted with laser or microwave beams. The use of lasers with solar sails would give very much improvements to that system. The problems with laser-systems are that the material of the targeted spacecraft would be heated in extreme temperature, but when we are thinking about the use of lasers as the improve the thrust of that very large sail, we must think this problem practically.


Big size of solar sails would allow that the heat of the laser rays would circulate in the larger area, and that would help to decrease the heat, what powerful lasers would send to the target.  Those lasers, what would be used in that kind of program, might be kilometers long, and they might be stationed near the Earth. Making those kilometers long free-electron lasers or powerful masers is a quite simple thing.


There must send many small satellites to space, and then those satellites must be connected together. In this case, those satellites would be equipped with the particle accelerator, what goes thru each satellite and then those satellites would be made very powerful ray, that can be targeted to the solar sail. In this case, the solar sail would be covered with ice, and that ice is no need to be made by water. Then the laser-ray would steam that ice, and that would improve the speed and thrust of the solar sail. This is the good thing to pump the energy for the spacecraft, that would send to Alpha Centauri in some day in future.  The use of lasers or masers would allow using the power source of the spacecraft with smaller power, and that would increase the system lifetime.


When we are thinking about the structure of that solar sail, we might think, that there would be very many small units in this probe, and it would look like some jewels are connected with the same spiders net and the miniaturization and multiplication of that system would improve the solar sails ability to survive that mission. And when this solar sai comes near Alpha Centauri, it would turn sideways to the star, and then increase the layer, what would face the solar wind of that star.  This would help it to transfer it to the orbital trajectory of that star.


And then it could send thousands of pea-sized miniature probes to the planets of that star. That would seem like science fiction, but using miniaturized probes that kind of mission would be done, and the destruction of one particle, would not destroy all probes, and this hypothetical mission would be accomplished surer than with one single probe.  There is only one problem with that system, those massive lasers can be mentioned as the military technology. And that would cause the resistance against this kind of projects.

Writing about the artificial cells and the changing the climate of the distant planets

When we are thinking about artificial cells or organisms, we must limit the texts and speeches in some part of the artificial organisms. There is three main part of the artificial cells. One is about the genetically engineered biological organism, second is the robot, what looks like example the snake or human and the third part of those artificial organisms is the factory, what makes copies about itself.


The third group of the artificial organisms can functionally imitate the natural organisms, but they will look like steel factories or something like that. Those factories can be equipped with 3D-printing systems, and laser cutters, what allows them to make many products. The 3D-printing systems will make that production more complying than using the fixed production equipment.


In the world of the artificial intelligence, is possible to make the factory, what has the capacity to make copies of itself. In this scenario, the factory might have robot equipment like robot caterpillars and other tools, what it can use for making another factory. In this text is mentioned theoretical system, what acts as the cell, but its size is much bigger than the normal cell. This kind of robot factories can be used in some theoretical operations, where some other planet like Venus would be modified similarly than Earth.


In that operation is needed very much bacteria and seaweeds, what will destroy the sulfur acid from that planet atmosphere, and then it must reduce the carbon from the carbon monoxide, what will reduce the oxygen in the atmosphere of that planet. In that operation is needed very much bacteria, and in this scenario, humans will send the automatic factory on that planet. In this fictional scenario, that factory has artificial intelligence, what allows it to make copies of itself. The artificial intelligence will allow the support vehicle to find the necessary chemical elements from the planet hemisphere, by using the laser spectrometer.

And then the automatic control system will make laboratories in those factories, what can produce the artificial bacteria and other necessary organisms in the atmosphere of Venus. In those operations where an entire atmosphere of the planet will change, is needed very many organisms, or the process will be very slow. And that is the reason, why that target planet must send the large-scale production units, what can deliver the very much bacteria on that planet atmosphere. I didn't create the idea of making other planets like earth.


But if we sometimes will travel to the stars, we might face the situation, where human will want to make another Earth in some other solar system. In that scenario, the cold planet will transfer to Earth, and in that operation, the atmosphere of some cold planet must fill with greenhouse gas. Then the atmosphere will start to warm, and if the reason for that operation would be making the colony in some distant solar system, the travel to that target would take thousands of years.


And in that operation, there might be sending the robot spaceship first to the target system, what could be some cold planet in Gliese 581 system. And then the robot spacecraft would start to change the climate on that planet for the suitable for human organisms. The robot spacecraft could send example 500 years before the colonialists would send to that distant system. And then the robots and the artificial intelligence will start to change the climate of the planet.
