American students decipher the mysterious 60 years of the belt of

A space mystery that hurts scientists for nearly 60 years has been successfully decoded by students at Colorado Boulder University in the US.

It is a mystery about the origin of energy molecules located in the inner area of ​​Van Allen radiation belt, the energy molecule that surrounds the Earth is anchored by the green planet's magnetic field. The effect of radiation belts is to protect us from the most harmful radiation effects in space.

For a long time, scientists have assumed that high-charge protons in these belts come from CRAND (cosmic ray albedo neutron decay, destruction of cosmic-ray reflective neutrons) , is what happens when the rays are cylinders break into neutrons in the Earth's atmosphere, such as explosions supernova. This process creates energy molecules trapped in the Van Allen belt. However, this theory is not extended to include electrons on the inner edge of the inner belts.

CRAND is also the cause of the high charge electrons.(Illustration).

Recently, a group of students from Colorado Boulder University confirmed that CRAND is also the cause of the high charge electrons mentioned above. This achievement is significant because it will help us predict the path of charged molecules. These charged molecules are a barrier for satellites and astronauts to penetrate the Earth's magnetosphere to fly into space (the magnetosphere is the area around the objects subject to control. of that celestial field word).

The mystery of the success of high charge electrons is successfully decoded thanks to a homemade tool: CubeSats satellite . CubeSats is a small satellite-sized bread or shoe box, subsidized to students through the NSF National Science Foundation (National Science Fund, a research and education grant program in the field of science). study and industry in America). More than 65 students of Colorado Boulder University have participated in designing and manufacturing small CubeSats under the guidance of a professor of space and atmospheric physics laboratory (LASP) of the school and another professor of scientific science technology space.

The work of Colorado Boulder University students has been published in the Wednesday issue of Nature magazine (December 13). American scientists hope that, when university and high school students in this country have more opportunities to access space, there will be more discoveries of this kind in the near future.

Van Allen Radiation Belt (Van Allen Radiation Belt) is a large radiation belt surrounding the outer Earth. Van Allen is made up of bodies and solar radiation molecules that carry charge from the upper atmosphere of the sun and stars. The position of Van Allen belt is at an altitude of 12-60 thousand km, surrounding the entire surface of the earth.

According to the Venus Project, no living creature from the earth can survive when crossing the Van Allen belt from the earth. This is because the high radiation emission of ionization or ionization of molecules will vaporize all living things that want to travel through Van Allen. This means that Apollo astronauts believed to have flown to the moon will evaporate immediately upon crossing the Van Allen belt, using rudimentary technology in the 1960s or today's most advanced technology. !
