Field Inversion

Recent observations, such as the magnetic field strength decrease, a magnetic poles shifts and the South Atlantic anomaly increase, may indicate the beginning of the Earth’s magnetic field inversion. According to the geomagnetic dynamo model, the dipole component of the magnetic field is zeroed at the inversion time, and the quadrupole one becomes dominant. To assess the occurrence of radiation hazards on the Earth’s surface and in near-Earth space at the time of magnetic field inversion, a numerical model was developed that made it possible to compare the GCR and SCR fluxes (at minima and maxima of solar activity) penetrating the Earth (taking into account the atmosphere) and the ISS in periods of the dipole and quadrupole fields dominance. It was found that during the period of inversion the flow of GCR (high-energy particles) can increase no more than three times over the entire surface of the Earth and the radiation dose will not exceed permissible one for man. Also, a change of the magnetic field configuration will redistribute areas of increased radiation on the Earth’s surface (today these are the poles of the Earth), which can adversely affect people’s health in these areas.

Near-earth space is being increasingly commercialised by private space companies. This has many consequences for science, particularly, astronomy. Some estimates show that more than 100,000 satellites may orbit the Earth by 2030. Satellite mega-constellations for satellite Internet connectivity are one of the main drivers behind the explosion in the number of satellites. Here, we note whether such satellite mega-constellations can justify their impact on astronomy.

The Earth

Intensive development of Near-Earth Space is accompanied by its microbiological contamination. Viable bacteria have been already detected on external structures of the International Space Station. A thin gaseous envelope and a layer of organic deposits are formed around a manned spacecraft. They can serve as a substrate for the evolution of some forms of microorganisms. As a result, the simplest natural-technical system is emerged in the near-Earth space. Biological objects can penetrate this system from the Earth’s atmosphere, or as gas leakage from the manned spacecrafts. In the nearest future the number of orbital space stations will increase many times. Some of them will be created by private firms for the purpose of space tourism development. Between the orbital stations and the Earth will be a constant transport of large numbers of people and cargos. Together with them microscopic biological objects will move in both directions. As a result of this, the natural-technical systems of space vehicles will integrate in the global natural-technical system — biotechnosphere. New strains of microorganisms which are hazardous to human may occur in the near-Earth space. The exploitation of a large number of manned stations in the Space hypothetically creates conditions for the penetration of alien life forms to the Earth. For timely identification of such threats it has been proposed to create an interdisciplinary scientific research complex. Its purpose is monitoring the appearance of new organisms at all stages of their movement from the near-Earth space to the Earth. Special attention should be paid to the study of biological objects detected on the Earth in areas hardly suitable for terrestrial microorganisms, for example, in different technological environments or clusters of toxic waste.
