NASA:s new laser propulsion can open the route to all Solar system

Laser propulsion spacecraft

NASA is testing new laser propulsion system, what is actually only the solar sail, what will give more push with the laser system. The laser will target the spacecraft, what is equipped with very large and thin mylar sheet, what takes the power of the movements also from the solar radiation. The small space-probe would be in the middle of sail, and its weight might be the only couple of grams because it is made with the state of art miniaturized technology, and equipped with highly developed artificial intelligence. That allows the spacecraft to operate independently in the all solar system.


But the high power laser systems can give more push to those spacecraft, and the unmanned lightweight version can reach the planet Mars in three days (72 hours), and manned version can travel that trip in the month, and this kind of vehicles can also travel all around our solar system. The mylar sheet is necessary because the very large area of that sheet will deliver the heat energy in the large area, and that denies the overheating of that structure. The mylar sheet might also use as the communication antenna if it will be covered by the very thin iron surface.


That antenna would also transmit the electric power to that very small space probe,  what can be made by the integrated micro-circuit technology. The electric supply will give the space probe with the radio-masers, what will also work as the communication systems. The manned system would be much bigger, and it can use the way that Nuclear rocket will be launched to the Martian orbiter to wait for the crew. And then the crew will send to Mars with this solar- or laser sail.


When the mission is completed, the crew will return to the Earth with the nuclear rocket. Using the laser to send the satellites in the Earth orbiter would give the NASA very cheap and clean way to shoot satellites outside Earth atmosphere. The laser is non-poisonous propulsion system, what is also noiseless and because there is no need for the chemicals, the launch will be extremely cheap. And because this powerful laser system can also use for ASAT (Anti Satellite) and ABM (Anti Ballistic Missile) purposes, and that's why also military forces might be interested in that laser-based equipment.

How to make RC-hobby more interesting? (Use of miniaturized technology in military and scientific operations)

Picture source: Internet

We all know about RC-cars. Those small remote controlled vehicles are a good hobby for some teenager or elder person. But if you want to get more about that thing, you just need one cell phone and take a video call, and now you can control your RC-vehicle even if you are not in visual contact with it. As the reader might already know that thing is simple, put cellphone where is a program for video call to RC-car and you can use other cellphones to see where you can drive.


Only thing what you must remember is remote controllers operative radius, and that will make your hobby simpler. Using "find my phone"-action you might see where you RC-car is going. But if you want to make your RC-car faster, just put there RC-airplanes combustion motor and servomotor what will use a carburetor. That small machine can replace gas pedal in this system.


Those kind of stuff are free to buy from net or hobbyists shops, and any person who is over 18 is allowed to buy a cellphone. If you want to make more fast RC-car, you just might want to make a hybrid vehicle, where combustion engine uses a small generator, what is connected to a small electric motor. Why electric motors make cars faster than combustion motors if they have enough electricity is that electric motor is rotating, and that's why it can have higher radial speed than combustion engine what uses to and from moving pistons. Most modern military intelligence equipment is also a size of RC-cars. Their mission is like more well-known flying drones, but that kind of tiny robot cars can go to tunnels and investigate them.


Those robots use inertial navigation system for record them the route, and if they lose communication to headquarters they can drive back, and retry communication. Those little cars can deliver their operation area by flying drones, and they can also carry small but effective explosives, like small HEAT-warheads or Fuel-air explosives. That new type of remote-controlled combat vehicles has a basis in German "Goliath" miniature tank. They drive under a tank or other target and shoot this shell to bottom of it. Or they can drive to ammunition warehouse and explode themselves in there.


NASA would also be interested in that kind of miniature recon vehicles, what could send to other planets to investigate their icy moons and surfaces. Those RC-car style systems will use state of art artificial intelligence and networked computing when they investigate other planets and moons surfaces. Technology is same as working with autonomous nano size helicopters. For electricity, those systems might use cesium-batteries for long-term operations. Those systems basis in technology where they can deliver their computer resources to another part of that group.


Those systems might be a hybrid, and if the target is Titan, there might operate both kinds of vehicles. Helicopters what can carry those probes what operates that moons surface. And even if those systems are not so sophisticated than Mars roves they can cover more of that moon surface than one single big rover. And if NASA loses one vehicle it will not put the mission at risk.
