Exploring the Mysteries of the Sun: Solar Orbiter's Major Missions
The Sun is the star that is the source of our life, and unraveling its secrets is one of the most fundamental goals of space exploration. Operated by the European Space Agency (ESA) Solar orbiter, is a revolutionary spacecraft designed to achieve this goal. Solar Orbiter is the first instrument to image the Sun's poles. This gives scientists the opportunity to gain new and unique insights into the Sun's magnetic field, cycle and overall functioning.
Solar Orbiter's Innovative Orbit
Most images of the Sun taken to date have been taken from the star's equator. This is primarily due to the Earth and other spacecraft orbiting the Sun. ecliptic plane is the rotation of the Sun in a plane called the Sun's orbit. However, the Solar Orbiter offers the opportunity to observe the Sun from a completely new angle by tilting its orbit outside this plane. In this way, it has been possible to obtain the first information about the Sun's poles.
First Images of the Sun's Poles
According to ESA, Solar Orbiter has observed the Sun from 17 degrees below the equator, allowing it to directly see the south pole of the star. This has enabled the first images of the Sun's poles to be recorded. In the coming years, Solar Orbiter will tilt its orbit even further to obtain clearer images of the poles. This is considered a new milestone in solar science.
Dispersion of Magnetic Fields
One of the first scientific findings from Solar Orbiter's polar observations is that the magnetic fields at the Sun's south pole are now chaotic While a normal magnet has a distinct north and south pole, Solar Orbiter's measurements show that the Sun's south pole has both a north and a south polar magnetic field. This divergence only lasts for a short time, "solar maximumIt is known that it occurs in a cycle.
The Importance of Solar Cycles
Every 11 years, the Sun completes its calm or stormy cycle and begins a new one. The Sun, which entered its 2019th cycle in 25, regularly changes its magnetic poles during these 11-year cycles. The calmer periods are “solar minimum" while the periods when explosions and spots increase are "solar maximum“ is called. Solar Orbiter makes a great contribution to the study of these cycles.
Effects of Geomagnetic Storms
It has been observed that the Sun frequently hosts spots and explosions, especially during the "solar maximum" periods. During these events, radioactive particles thrown into space reach the Earth Solar Storms or geomagnetic storms. Solar storms can disrupt GPS systems and radio waves, causing serious disruptions to communications on Earth and even power outages. These storms can also affect satellites in orbit, creating dangerous situations for astronauts.
Future Exploration with Solar Orbiter
Scientists have long sought to predict these storms. Solar Orbiter’s measurements could reveal how these particles are ejected in the form of the solar wind. Understanding how the Sun produces these storms is one of the mission’s key scientific goals. Data from Solar Orbiter could revolutionize solar physics.
