From Science News:
'Space hurricanes' churn at both of Earth's magnetic poles
Carolyn Gramling
July 12, 2024
On Earth, hurricane season isn't just surface level. The
ionosphere, an upper layer of the atmosphere charged by solar
radiation, also contains swirling storms of plasma dubbed "space
hurricanes." Scientists first described a space hurricane in
2021: It was a cyclone-shaped aurora, swirling for hours near
Earth's north magnetic pole and raining down electrons, rather
than water, into the upper atmosphere.
Now, new research reveals that parallel space hurricanes swirl
near the south magnetic pole as well.
An analysis of satellite data collected from 2005 to 2016
identified 259 space hurricane events in the Southern
Hemisphere's ionosphere, space physicist Sheng Lu of Shandong
University in Weihai, China, and colleagues report June 25 in the
Journal of Geophysical Research: Space Physics. That's about 23
events per year on average, which is close to the rate that was
previously estimated for the Northern Hemisphere. The team
identified other symmetries too. For instance, space hurricanes
in both hemispheres tend to occur in summer months.
The researchers suspect that the storms are driven by shifts in
Earth's magnetic field caused by the solar wind. This barrage of
charged particles from the sun splits magnetic field lines. When
the lines reconnect, they roil ionized gas in the ionosphere,
driving flows of electric current upward, the team suggests.
Flows then bend and begin to spin, leaving an "eye" at the
center. That proposed process would be akin to the rise of warm,
humid air at the center of a tropical cyclone.

From Phys.org:
NASA's ICON mission ends with several ionospheric breakthroughs
by Desiree Apodaca NASA's Goddard Space Flight Center July 24,
2024
After contributing to many important findings on the boundary
between Earth's atmosphere and space, the Ionospheric Connection
Explorer (ICON) mission has come to an end. ICON launched in
October 2019 and after completing its two-year mission objectives
in December 2021, it operated as an extended mission for another
year.
"The ICON mission has truly lived up to its name," said Joseph
Westlake, heliophysics division director at NASA Headquarters in
Washington. "ICON not only successfully completed and exceeded
its primary mission objectives, it also provided critical
insights into the ionosphere and the interplay between space and
terrestrial weather."
The ICON spacecraft studied a part of our planet's outermost
layer of the atmosphere, called the ionosphere. From there, ICON
investigated what events impact the ionosphere, including Earth's
weather from below and space weather from above.
The ionosphere is the lowest boundary of space, located between
55 miles to 360 miles above Earth's surface. It is made up of a
sea of particles that have been ionized, a mix of positively
charged ions and negatively charged electrons called plasma. This
frontier of space is a dynamic and busy region, home to many
satellites—including the International Space Station—and is a
conduit for radio communications and GPS signals.
Both satellites and signals can be disrupted by the complex
interactions of terrestrial and space weather. Studying and
understanding the ionosphere is crucial to understanding space
weather and its effects on our technology.
The ICON mission captured unprecedented data about the ionosphere
with direct measurements of the charged gas in its immediate
surroundings alongside images of one of the ionosphere's most
stunning features—airglow.
ICON tracked the colorful bands as they moved through the
ionosphere. Airglow is created by a process similar to what
creates the aurora. However, airglow occurs around the world, not
just the northern and southern latitudes where auroras are
typically found. Although airglow is normally dim, ICON's
instruments were specially designed to capture even the faintest
glow to build a picture of the ionosphere's density, composition,
and structure.
Through the principle of Doppler shift, ICON's sensitive imagers
also detected the motion of the atmosphere as it glowed. "It's
like measuring a train's speed by detecting the change in the
pitch of its horn—but with light," said Thomas J. Immel, ICON
mission lead at the University of California, Berkeley. The
mission was specifically designed to perform this technically
difficult measurement.
A new ionospheric perspective
The ICON mission's comprehensive view of the upper atmosphere
provided valuable data for scientists to unravel for years to
come. For instance, its measurements showed how the 2022 Hunga
Tonga-Hunga Ha'apai volcanic eruption disrupted electrical
currents in the ionosphere.
"ICON was able to capture the speed of the volcanic eruption,
allowing us to directly see how it affected the motion of charged
particles in the ionosphere," Immel said. "This was a clear
example of the connection between tropical weather and
ionospheric structure. ICON showed us how things that happen in
terrestrial weather have a direct correlation with events in
space."
Another scientific breakthrough was ICON's measurements of the
motion of ions in the atmosphere and their relationship with
Earth's magnetic field lines. "It was truly unique," Immel
remarked. "ICON's measurements of the motion of ions in the
atmosphere was scientifically transformational in our
understanding of behavior in the ionosphere."
With ICON's help, scientists better understand how these
interactions drive a process called the ionospheric dynamo. The
dynamo, which lies at the bottom of the ionosphere, remained a
mystery for decades because it is difficult to observe.
ICON provided the first concrete observation of winds fueling the
dynamo and how this influences space weather. Unpredictable
terrestrial winds move plasma around the ionosphere, sending the
charged particles shooting out into space or plummeting toward
Earth. This electrically charged tug-of-war between the
ionosphere and Earth's electromagnetic fields acts as a
generator, creating complex electric and magnetic fields that can
affect both technology and the ionosphere itself.
"No one had ever seen this before," Immel said. "ICON finally and
conclusively provided experimental confirmation of the wind
dynamo theory."
An iconic legacy
On Nov. 25, 2022, the ICON team lost contact with the spacecraft.
Communication with the spacecraft could not be established, even
after performing a power cycle reset using a built-in command
loss timer. Though the spacecraft remains intact, other
troubleshooting techniques were unable to re-establish contact
between the ICON spacecraft and mission operators.
"ICON's legacy will live on through the breakthrough knowledge it
provided while it was active and the vast dataset from its
observations that will continue to yield new science," Westlake
said. "ICON serves as a foundation for new missions to come."
