NASA sends probes to map poles of the sun

NASA (National Aeronautics and Space Administration) of the United States and the ESA (European Space Agency) will send space probes to the sun to map its poles. The solar orbiter was launched on February 9, 2020.


The probe will use gravitational influence of the Earth and Venus to position itself at 26 million miles from the sun. It is 95% of distance between the sun and the earth. The probe will map the poles for the first time. This will help scientists to observe the solar winds. The solar winds permeate the solar system.

Solar Winds

The solar winds are released from the upper atmosphere of the sun. These winds carry charged particles and magnetic clouds from the sun. These winds are capable of damaging life on the earth. Therefore, it is important to learn about these winds. They are now being filtered by the thick atmosphere around the earth.

The winds are a reason for the planets including the earth to revolve around the sun.
