Breaking news! The Solar Orbiter will make the first flyby of the Earth before I begin the mission. ESA recently announced that its Solar Orbiter and JAXA mission to explore the Sun, will start after this overflight. It will be the most risky overflight ever made by ESA and JAXA, as the satellite must pass through clouds of space debris orbiting the Earth. The flight will start on November 27, at 05:30 CET. According to the latest details, the satellite will approach approx. 460 km from North Africa, which means somewhere near the orbit of the International Space Station (ISS). Why does this fly over? This overflight is not mandatory when a satellite goes on a mission to explore the Sun. But, ESA and JAXA have calculated that this overflight helps the staelit not to consume so much of the energy it has. 

This decrease in the energy that the satellite consumes will help it for the very large overflight that it will make around the Sun. This overflight is therefore very effective, but as I said above it is also very risky. The satellite must pass through space debris and not just to one side, it must pass through two regions of space debris. It must pass through a fairly large area and another very close to the Earth. 

The regions are as follows: 

- at 36,000 km is the geostationary ring of satellites, so impacts can occur here if the satellites in orbit are not properly coordinated, so as to let the Solar Orbiter pass; 

- and if he got rid of the first, the second is not so easy, the next group of space debris is 400 km from Earth, full of satellites and other space debris that can not be controlled.

So there is a high risk of impact between satellite and space debris. But, we hope that does not happen. "The team operating the Solar Orbiter is monitoring the situation closely and will change the satellite's trajectory in case of danger." transmitted ESA. In addition to the benefits of this flyover for Solar Orbiter's mission, there are other benefits for us. We will discover in detail the most important things about the Earth's magnetic field. The Solar Orbiter will study the earth a little and even penetrate its magnetic field, thus studying it. It will probably be a unique opportunity to truly see the mysteries of the Earth's magical field, as well as the particles from the solar winds and atoms in our atmosphere.

To get an idea of ​​where the Solar Orbiter will end up, you can figure out where our satellites are now and why they can't study the magnetic field in detail, and the Solar Orbiter can. For example, the Cluster stars (4 in number) are located at an altitude of 60,000 km. Swarn satellites (3 in number) are located at an altitude of 400 km. And, the Solar orbiter will try to get even closer to the Cluster satellites and very close to the Swarn, but Solar Orbietr technology surpasses that of the Swarn satellites. 

The mission of JAXA and ESA is taking the first steps at this time to get closer to the Sun, making it fly over it. JAXA and ESA will do a lot of checks, experiments and will collect a lot of data about the Sun. Also, ESA has another mission with BepiColombo who has already made the first flyby of Venus and he has to study the planet Mercury.  Through these missions of ESA and JAXA, one of the parts of the huge space will be explored at a very high capacity. Through these programs, the closest planets to the Sun will be studied, including the Sun itself. Exploration of the two planets is unique in terms of acre technology being studied this year and in the years to come. 

We wish success to the satellites, space agencies and all those who work for these missions.
