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.

Will humans survive the sun's red giant stage?

"As the Sun matures into a Red Giant, the oceans will boil and Earth will become uninhabitable." (The Conversation, The sun won’t die for 5 billion years, so why do humans have only 1 billion years left on Earth?) Sooner or later, all stars use their hydrogen. And then they turn into red giants. Sun is a yellow G spectral class star that turns into a white dwarf. But before that, the sun will turn larger. The sun turns red and that means. It starts to send more infrared radiation. This thing will turn Earth into a hellish temperature that vaporizes water from Earth. It's possible. That Earth will also vaporize with Venus and Mercury. Some scientists say that we have only 1 billion years to move farther in the solar system. The habitable zone will go to the distance of Jupiter and Saturn, and maybe humans find a safe place in those distant moons. It's possible that before Sun will grow too large humans make large groups of mirror satellites or large shields that sho...

Research with hypersonic systems is not an easy thing.

"This is an artist’s depiction of a Hyper-X research vehicle under scramjet power in free-flight following separation from its booster rocket. New research into hypersonic jets may transform space travel by making scramjet engines more reliable and efficient, leading to aircraft-like spacecraft. Credit: NASA" (ScitechDaily, Revolution at Mach 10: NASA-Backed Hypersonic Jets Poised to Transform Space Travel) The main problem with hypersonic systems is how to control them on air. If the hypersonic aircraft's body is designed the wrong way, that causes thermal problems. But another problem is this: if the aircraft's shape is wrong, the pressure wave or sonic boom will go past the control surfaces. And those layers will not work in that case. In other cases, if the shockwave nuzzles against the aircraft body, that causes overheating. The next problem is the engine. The Scramjet engine is the only engine type that can use atmospheric air and create hypersonic exhaust gas....

Metamaterials can change their properties in an electric- or electro-optical field.

"Researchers have created a novel metamaterial that can dynamically tune its shape and properties in real-time, offering unprecedented adaptability for applications in robotics and smart materials. This development bridges the gap between current materials and the adaptability seen in nature, paving the way for the future of adaptive technologies. Credit: UNIST" (ScitechDaily, Metamaterial Magic: Scientists Develop New Material That Can Dynamically Tune Its Shape and Mechanical Properties in Real-Time) Metamaterials can change their properties in an electric- or electro-optical field. An electro-optical activator can also be an IR state, which means. The metamorphosis in the material can thermally activate. AI is the ultimate tool for metamaterial research. Metamaterials are nanotechnical- or quantum technical tools that can change their properties, like reflection or state from solid to liquid when the electric or optical effect hits that material. The metamaterial can cru...
