Turning Pictures into Physics – Solar ‘Camps’, Space and Dispersion Comets

Recent results from Solar Orbury show that the mission is making the first direct link between events on the surface of the sun and the space around the spacecraft. It is also giving us new insights into solar ‘camp fires’, weather conditions and dispersal comets.

“I was more than happy with the performance of the Solar Orbiter and the performance of the various teams that maintain it and the operation of your device,” said Daniel Mueller, an ESA Solar Orbit Project Scientist.

This year has been a real team effort under difficult circumstances, and now we are beginning to see that effort is truly rewarding.

The ten scientific devices of the solar system are divided into two groups. There are six remote navigation telescopes and four on-site equipment. The remote sensing devices look at the sun and the vast atmosphere, the corona. The instruments in the space measure the particles around the spacecraft, known as the solar wind, with magnetic and electric fields. One of the main purposes of the solar system is to monitor the origin of these particles and fields on the surface of the sun.

Linn During the first solar eclipse on June 15, the spacecraft was approaching 77 million kilometers when it was approaching the sun.

Solar winds

Solar orbiter data can be used to calculate the area of ​​the solar plexus on a spacecraft and to keep this ‘imprint’ in remote navigation images. Linn In the June 2020 example, the fingerprint is visible on the edge of the coronary hole, where the sun’s magnetic field, which allows sunlight to flow through the atmosphere.

Although the work is preliminary, it is still more than possible.

“We have not been able to make this exact map before,” said Tim Horbury, chairman of the London Imperial College and Solar Orbury In-City team.

Camp Fire Physics

The solar system has also caught the attention of the world earlier this year with new information about the ‘fire hazard’.

The first images of the mission show much of what looks like tiny solar flares exploding on the surface of the sun. Scientists have dubbed them campfires because the exact force behind these events is still unknown. It is not yet clear whether other mines have seen the same impact on other missions. It has long been thought that there are tiny ‘nano-flames’ in the sun that illuminate everything, but we have not been able to see these tiny phenomena before.

Campfire fires can be nano-flames that follow the solar orbiter, says Frederick Achre, chairman of the organization’s astrophysicist Spanish, French and solar orbiter remote sensing team.

This is important because nano-flares are ideal for heating the outside environment, the corona. The fact that the corona is about a million degrees Celsius The surface area is only up to 5,000 degrees and is still one of the most confusing issues in solar physics. Exploring this secret is one of the key scientific purposes of the solar system.

To explore this idea, the researchers are analyzing data from Solar Orbury Spy’s (Spanish Emogram of the Coronary Environmental) instrument. SPICE is designed to detect the speed of gas on the surface of the sun. It has been shown to be available at low speeds at high speeds but has not yet been identified in connection with the campfire fire.

We still only have commission information that was taken while the teams were still learning the features of their devices in place, and the results are very original. But obviously we are seeing something very interesting, ”says Frederick. “The solar orbital is about discovery, and that’s very exciting.”

Exploring Comet Tail

There is also a science that is unique to the spacecraft.

Shortly after the project began, it was announced that it would pass through two tails and fly down to Comet Atlases. Although the solar orbiter was not designed for such an event, it did not carry scientific data at this time, and mission experts worked to ensure that all equipment on the site recorded a unique experience.

But nature had one more way to play: The comet disintegrated before the spacecraft approached. So it was quite possible that the space shuttle would never see anything better than its tail.

That was not the case. The Solar Orbiter saw the signatures from Comet ATLAS, but it was not what scientists usually expect. Instead of a solid single tail crossing, the spacecraft found a number of waves in its magnetic field. Dust was also found in the patch. This was probably broken into small pieces and released from the comet.

Tim says: “This is our first time on a fundamentally scattered comet. There is a lot of interesting information out there, and another example of high-quality art science that we can do with a solar orbiter.

Hidden space weather

Solar Observatory has recorded a number of tiny particles from the sun, often measuring the amount of sunlight in space. Since then. On April 19, a particularly exciting artery flooded the solar system.

Coronal mass ejection, or MME, is a major atmospheric phenomenon in which billions of tons of particles can be released from the sun’s atmosphere. During this special CM, created by the sun on April 14, the solar orbital pathway was about 20 percent.

Comprehensive investigations of a coronary mass exudation

A few months after the launch of the solar orbate, in February, it measured the arterial pressure from the sun. The same measurements from the other ESA and NASA spacecraft allowed the evolution of CM to take place during a five-day solar orbit. Credit-ESA

Solar Observers are not the only spacecraft to have witnessed this phenomenon. EPA’s Bepi Colombo Mercury mission was flying on Earth at the time. And there was one NASA It is directly visible from the solar eclipse, which is about 90 degrees straight from the Sun-Earth line. The effects of CME have been observed in solar energy orbits and then in Bepicolombo and Earth. Combining the measurements of all the various spacecraft, it allowed researchers to truly study how coronary mass extinguishing was performed while traveling in space.

This is known as multi-point science, and it is becoming an increasingly powerful tool in our search for solar wind and space for the number of spacecraft in the solar system.

“We can look at it from a distance, measure it in place and see how a CME changes when it travels to Earth,” says Tim.

They were probably not as spectacular as the spacecraft. ESA-NASA Soho He never recorded a spacecraft orbiting the sun on the surface of the earth. This April 19 event will feature an unusual space weather event, called the “Hidden” CME. Studying these incomprehensible arrangements will help us to better understand the atmosphere.

In the coming years, multi-point science opportunities will increase. Linn On December 27, the solar orbital completes its first Venus The flyby will turn the planet’s gravitational space closer to the sun, making it even better to measure the solar orbiter together with NASA Parker Solar Proverb, which in 2021 will complete two Venus Flybies.

Just as Parker measures the interior of the solar atmosphere, the solar orbiter takes pictures of the same region. Together, the two spacecraft provide both the details and the larger image.

“2021 will be an exciting time for solar orbit,” said Teresa Niev-Chinchila, a scientist at NASA’s solar orbital project scientist. “By the end of the year, all the devices will be working together in science mode and we are getting ready to even approach the sun.”

Linn By 2022, the solar orbital will be 48 million km from the sun, more than 20 million km by 2021.
