When the U.S. military dropped a 1.4 megaton atomic bomb into orbit on July 9, 1962, high-energy electrons released by radioactive debris from an exploding bomb did not have a positive effect on and destroyed the world's first communication satellites some of their electronics and made them unusable. Solar panels of the most modern devices of the time. Such an event could be attributed to the cost of the Cold War between the United States and the Soviet Union, if not for a "but" in the face of modern North Korea, which has nuclear weapons in the absence of space satellites. To protect against the possible effects of radiation, American scientists are trying to invent an effective "medicine" for orbit.
How do you get rid of radiation?
Radiation is harmful ionizing radiation that has a devastating effect on every biological life. According to an article published on sciencemag.org, American scientists are planning to send three spacecraft into orbit around our planet to collect data on how humanity can get rid of the high-energy electrons captured by the planet's magnetic field. This process, called Radiation Belt Recovery (RBR), normally occurs naturally when radio waves from space or from Earth trap electrons trapped in Van Allen's radiation belt into the upper atmosphere, where they quickly lose energy and often cause energy to Aurors.

The researchers are currently ready to attempt artificial restoration by emitting radio waves in the Van Allen belt. To accomplish such an ambitious task, US physicists tested with the US Navy's low-frequency antenna towers (VLF) – powerful military communication tools for communication with submarines. Each of these antennas has an important task – to send VLF waves to Van Allen bands and to measure the deposited particles with the help of on-board detectors.
A team of scientists from Los Alamos and NASA's Goddard Space Flight Center is leading a second experiment on low-frequency particle separation. Therefore, the team plans to launch a rocket in April 2021, which contains an experiment on the interaction of a plasma jet with a miniature accelerator. An electron beam is generated that generates VLF waves with which particles can be picked up. Researchers believe that such a compact electron accelerator is a better way to protect against radiation than a giant VLF antenna, the dimensions of which are the size of a soccer field.

The third experiment, which has been proposed by scientists, can only be carried out in 2021 at the earliest when the US Naval Research Laboratory plans to launch a mission called "Space Measurements of Turbulence from a Missile". A sounding rocket will fly into the ionosphere – a special atmospheric layer hundreds of kilometers high that is filled with ions and electrons and throws about 1.5 kilograms of barium atoms. Barium is ionized by sunlight and creates a ring of moving plasma that emits radio waves. Such a cleaning of space would help protect humanity from the consequences of a nuclear explosion, and could, among other things, protect future astronauts from the impact of high-energy electrons if the spacecraft enters the danger zone of radiation belts.
