Description

Cosmic dust

Cosmic dust consists of tiny particles of solid material floating around in the space between the stars. Countless plenty of dust grains, including samples of asteroids and comets fall from space onto the Earth's atmosphere every day. These small particles are the most important source of extra-terrestrial material accreting on the present-day Earth. The formation of cosmic dust on Earth is generally assumed to be constant as it is not a function of any terrestrial process of enrichment or depletion as is known to be the case for cosmic rays. These cloud particles are also often called micrometeoroids.

Effects on Earth

Earth’s magnetic flux normally protects us from space weather. But during a strong solar storm, Earth’s magnetic flux can buckle. This is most often seen when the storm is accompanied by a coronal mass ejection. These particles can cause damage to the electronic circuits of spacecraft and indeed to the DNA of astronauts or other living things in space. One significant influence of solar activity is seen in disturbances in satellite navigation services like Galileo. Geomagnetic storms also produce the aurora. Space weather will impact people that depend on this technology. These electrical currents degrade solar panels or various instruments, mainly by ionising the coatings. Additionally, they will corrupt the programming of onboard computers, which could lead to the loss of the satellite. Outside the magnetosphere, satellites are exposed to solar radiation, which is usually not very aggressive but becomes so when the sun expels protons of very high energy. When this happens the fast-moving particles are guided by the Earth's magnetic flux lines toward the poles where they can penetrate the atmosphere. These electrical currents degrade solar panels or various instruments mainly by ionizing the coatings. The consequences of space weather can be seen in the degradation of communications, performance, reliability, and overall lifetime. The world and its magnetic field constitute an obstacle that the solar wind must circumvent. In the absence of a solar wind the influence of the global magnetic field is limited. The intensities of upper-energy particles in the magnetosphere can change by many orders of magnitude over the course of minutes, hours, and days. These intensity increases occur through a spread of processes including physics energization processes in the magnetosphere and ready access of solar particles.
