Subsequent flybys of Venus will begin to increase the inclination of the spacecraft’s orbit to gain access to higher latitudes - more polar - regions of the Sun.Orbit Baby Gear is like nothing you’ve ever seen before in the world of strollers and car seats. Earlier this month, on September 4, Solar Orbiter undertook a gravity-assist flyby of Venus to adjust its orbit around the Sun.

Solar Orbiter’s next close flyby of the Sun - again inside Mercury’s orbit at a distance of 0.29 times the Earth-Sun distance - is on October 13. This was Solar Orbiter’s first-ever close flyby of the Sun, so we expect many more exciting results.” Based on results like these, we will refine the observations planned for Solar Orbiter’s next solar encounter to understand how the Sun connects to the broader magnetic environment of the Solar System. “With each orbit, we get more data from our suite of ten instruments. “This is exactly what we hoped for for Solar Orbiter,” says Daniel Müller, ESA project scientist for Solar Orbiter. As long as the in situ data and the remote sensing data match, Daniele can perform the correlation. It could be another spacecraft like Parker Solar Probe. This is exactly the kind of linkage science Solar Orbiter was designed for, but that doesn’t necessarily mean Solar Orbiter has to fly through the Serpentine. In other words, fly a spacecraft through magnetic reversal and see what happened on the sun’s surface. “The next step is to try to statistically link serpentines observed on site to their regions of origin on the Sun,” says Daniele. Because when spacecraft fly through serpentines, they often register a local acceleration of the solar wind. The results turned out to be absolutely spectacular!”īy understanding serpentines, solar physicists could also take a step towards understanding the details of how the solar wind is accelerated and heated away from the sun. Of course, the first image was just a snapshot, and we had to dampen our enthusiasm until we took advantage of the excellent Metis coverage to extract temporal information and perform a more detailed spectral analysis of the images themselves. Much like the cracking of a whip, this releases energy and triggers an S-shaped disturbance that propagates into space, which a passing spacecraft would record as a U-turn.Īccording to Gary Zank, who proposed one of the theories for the origin of serpentines, “Almost immediately, the first picture of Metis that Daniele showed me suggested the cartoons we had drawn while developing the mathematical model for a serpentine. When the field lines crowd together, they can reconnect into more stable configurations.

They are magnetic highways along which plasma is free to flow and generate the fast solar wind.ĭaniele and Gary proved that switchbacks occur when there is an interaction between a region of open field lines and a region of closed field lines. Open field lines are reversed, emanating from the Sun and connecting to the Solar System’s interplanetary magnetic field. Above these field lines, very little plasma can escape into space, so solar wind speeds tend to be slow here. The closed lines are magnetic loops that bulge into the Sun’s atmosphere before looping and disappearing back into the Sun. The theory examined how different magnetic regions near the Sun’s surface interact with each other.Ĭlose to the Sun and especially over active regions, there are open and closed magnetic field lines. Gary Zank, University of Alabama at Huntsville, USA. Further analysis of the Metis data showed that the velocity of the plasma over this region was very slow, as would be expected from an active region that has yet to release its stored energy.ĭaniele immediately thought that this was similar to a serpentine generation mechanism proposed by Prof. Active regions are associated with sunspots and magnetic activity.

It looked suspiciously like a solstice to Daniele Telloni of the National Institute for Astrophysics – Astrophysical Observatory of Turin, Italy.Ĭomparing the Metis image captured in visible light with a simultaneous image captured by Solar Orbiter’s Extreme Ultraviolet Imager (EUI) instrument, he saw that the candidate occurred over an active region cataloged as AR 12972. At about 20:39 UT, Metis acquired an image of the solar corona that revealed a distorted S-shaped kink in the coronal plasma.
