 For the first time probe has touched the Sun. 

NASA Parker probe has been dive in the Sun. That probe used interesting technology that helped to keep it cool. There could be possible to make the probe dive even deeper by using a magnetic field that pushes the plasma away from the probe. That would decrease the interaction between the probe and the plasma that comes from the Sun. 

The reason why Parker was sent to its mission. Is that it should collect data from the solar wind. The solar wind is high-energetic plasma that can destroy spacecraft. But there is another reason why close contact with the Sun is needed. The mission of probes like Parker is to collect data for the fusion tests. The power source of the Sun is fusion reaction. And the close contact with the Sun is the thing that can help to model the conditions that are making fusion possible. 

In some visions, the probes like Parker can collect antimatter from the solar atmosphere. The probe would travel to the sun.  Then that antimatter collector dives deep into the corona. Then it could open the solar sail and solar wind can push the probe back to Earth. 

Antimatter production is extremely expensive. And the probe could create it by putting the beta particles of the solar wind impact with gold leaf. Antimatter can use in fusion reactors to start the fusion reaction. 

The antimatter is creating an extremely high energy load. And that energy can use for starting and maintaining fusion reactions. The antimatter can make annihilate with material around the plasma-ring at Tokamak-type reactors. And that energy dose can start a fusion reaction. And it can raise the temperature after certain periods. The use of antimatter is to boost the fusion reaction in the fusion reactors. 

When the fusion reactor will start to turn too cold small dose of antimatter can turn the temperature to the needed level. The problem with the fusion rector is that the needed temperature is higher than in the Sun's nucleus. In the fusion reactors, the pressure of the nucleus of the sun must compensate by rising temperature to so high level. That the heat replaces missing pressure.  

The use of antimatter is one of the answers to how to create enough energy for starting self-maintaining fusion. But the high price would limit the use of antimatter for that purpose. So antimatter can collect from space.

Thorium 232, the next-generation nuclear fuel. For civil and military purposes.

Could Thorium-232 be the next generation nuclear fuel that replaces uranium? The difference between uranium and thorium reactors is that the thorium reactor requires the energy booster that it can maintain the nuclear reaction. In the case of the accident, the requirement for stopping the reaction is that crew will cut off that accelerator. And the reaction would stop immediately. 

Thorium-232 allows creating the next-generation nuclear reactors that are not creating radioactive waste. The price of thorium is lower than uranium. And the only difference between thorium- and uranium reactors is that thorium reactor requires a heating system. 

Or accelerator for making the energy for thorium fusion. The thing is that the thorium would make it possible to create more effective nuclear reactors. And its use in ships and especially in submarines and aircraft is an interesting opportunity. 

Also, thorium reactors can be used in fission rockets. Starting the reactor requires an accelerator that can take its energy from the regular electric power plant. So the accelerator would not be a problem. When the use of thorium as the nuclear fuel is mentioned. 

The use of thorium removes the thing that is giving breaks for full-scale benefiting the nuclear systems. That thing is the highly radioactive pollution. The question is why thorium is not used before? 

The thing is that thorium can be used in nuclear weapons that are not leaving a radioactive mark. In that case, high-energetic electromagnetic radiation like laser rays and quantum annealing systems are used to release an extremely high number of neutrons and energy to thorium. 

The depleted uranium of special ammunition can replace by using thorium. The radioactivity of that ammunition is problematic. In that type of ammunition, the thorium round travels inside the laser ray. And that thing can create nuclear fission when that ammunition hits to target. 

And that kind of system can use in the triggers of thermonuclear weapons. The nuclear weapon that is using thorium as the primary stage requires an extremely high-power energy load to the thorium fuel. The thing is that this type of clean and powerful system is interesting to both, civil and military authorities.
