Is Low Earth Orbit Getting Too Crowded?
Hundreds of satellites may soon be flying in orbital regions that are
already too packed to allow safe and long-term operations, a new study
suggests.
The study found that, while in 2019 only 0.2% of satellites in Earth orbit
were forced to perform more than 10 collision-avoidance maneuvers per
month, that percentage had risen sevenfold by early 2025, to 1.4%. That
number might still seem low, but it means that some 340 satellites spend a
lot of time dodging debris and other spacecraft.
Moreover, the satellite population is set to keep growing. While in 2019
about 13,700 objects (including space junk) zoomed around the planet in low
Earth orbit (LEO), at altitudes below 1,200 miles (2,000 kilometers), that
number has since risen to 24,185 objects in 2025, an increase of 76%,
according to the study. By the end of this decade, some 70,000 satellites
may reside in LEO, according to industry growth predictions, representing a
more than fivefold increase compared to the 2019 situation.
[image: Debris_field_pillars.jpg]
*Artistâ€Ös rendering of space junk in orbit[Image: European Space Agency]*
The study, conducted by William E. Parker, Maya Harris, Giovanni Lavezzi,
and Richard Linares of the Department of Aeronautics and Astronautics,
Massachusetts Institute of Technology, was published September 26 in the
journal, *Acta Astronautica*. The research was sponsored by the Department
of the Air Force Artificial Intelligence Accelerator.
The authors selected 10 collision-avoidance maneuvers per month as a
threshold at which satellite operation may become too complicated to be
beneficial. Different operators choose a different threshold to perform
collision-avoidance maneuvers. NASA spacecraft mostly maneuver when the
collision risk is greater than 1 in 10,000. SpaceX â€ö the worldâ€Ös biggest
satellite operator, with its Starlink broadband megaconstellation â€ö is
more cautious, using its autonomous space dodging system to avoid an
object posing a risk greater than 1 in 3.3 million. Frequent maneuvers
present a disruption to operations that some satellite handlers are
better able to absorb than others.

Swarm Reveals Growing Weak Spot in Earthâ€Ös Magnetic Field
Using 11 years of magnetic field measurements from the European Space
Agencyâ€Ös Swarm satellite constellation, scientists have discovered that the
weak region in Earthâ€Ös magnetic field over the South Atlantic – known as
the South Atlantic Anomaly – has expanded by an area nearly half the size
of continental Europe since 2014.
Earthâ€Ös magnetic field is vital to life on our planet. It is a complex and
dynamic force that protects us from cosmic radiation and charged particles
from the Sun.
It is largely generated by a global ocean of molten, swirling liquid iron
that makes up the outer core around 3000 km beneath our feet. Acting like a
spinning conductor in a bicycle dynamo, it creates electrical currents,
which in turn, generate our continuously changing electromagnetic field â
€“
but in reality the processes that generate the field are far more complex.
Swarm, an Earth Explorer mission developed under ESAâ€Ös Earth Observ
ation
FutureEO programme, comprises a constellation of three identical satellites
that precisely measure the magnetic signals that stem from Earthâ€Ös core,
mantle, crust and oceans, as well as from the ionosphere and magnetosphere.
Thanks to this exceptional mission, scientists are gaining more insight
into the different sources of magnetism to help understand how and why the
magnetic field is weakening in some places and strengthening in others.
[image: South_Atlantic_Anomaly_2025_compared_to_2014_article.webp]
The weak field South Atlantic Anomaly was first identified southeast of
South America back in the 19th century.
Today, the South Atlantic Anomaly is of particular interest for space
safety, as satellites passing over the region are faced with higher doses
of incoming radiation. This can lead to malfunctions or damage to critical
hardware, and even blackouts.
Published this month in Physics of the Earth and Planetary Interiors, the
latest results from the Swarm mission reveal that while the South Atlantic
Anomaly expanded steadily between 2014 and 2025, a region of the Atlantic
Ocean southwest of Africa has experienced an even faster weakening of
Earthâ€Ös magnetic field since 2020.
“The South Atlantic Anomaly is not just a single block,†says lead author
Chris Finlay, Professor of Geomagnetism at the Technical University of
Denmark. “Itâ€Ös changing differently towards Africa than it is near South
America. Thereâ€Ös something special happening in this region that is
causing
the field to weaken in a more intense way.â€
This behaviour is linked to strange patterns in the magnetic field at the
boundary between Earthâ€Ös liquid outer core and its rocky mantle, known as
reverse flux patches.
Prof. Finlay explains, “Normally weâ€Öd expect to see magnetic field lines
coming out of the core in the southern hemisphere. But beneath the South
Atlantic Anomaly we see unexpected areas where the magnetic field, instead
of coming out of the core, goes back into the core. Thanks to the Swarm
data we can see one of these areas moving westward over Africa, which
contributes to the weakening of the South Atlantic Anomaly in this region.
â€
*Swarmâ€Ös record-breaking 11 years*
The latest model of Earthâ€Ös core-generated magnetic field marks a new
milestone for ESAâ€Ös Swarm satellites, which have now provided the longest
continuous record of magnetic field measurements from space.
The satellites were launched on 22 November 2013 as the fourth Earth
Explorer mission, pioneering satellites that form a key component of ESAâ€Ös
forward-looking FutureEO programme.
Conceived as demonstrators of innovative Earth observation technologies,
these missions have long outlived their original design lifetime, become
integral to long-term records, provided data for critical operational
services, and have paved the way for future generations of satellites.
Swarm data underpin the global magnetic models used for navigation, monitor
space weather hazards, and allow unprecedented insights into our Earth
system from its core through to the outer reaches of Earthâ€Ös atmosphere.
*Earthâ€Ös magnetic field strengthens over Siberia*
The latest Swarm results highlight the dynamic nature of Earthâ€Ös magnetism.
For example, in the southern hemisphere there is one point where the
magnetic field is particularly strong, and in the northern hemisphere there
are two – one around Canada and the other around Siberia.
“When youâ€Öre trying to understand Earthâ€Ös magnetic field, itâ€Ös important to
remember that itâ€Ös not just a simple dipole, like a bar magnet. Itâ€Ös only
by having satellites like Swarm that we can fully map this structure and
see it changing,†said Prof. Finlay.
However, since Swarm has been in orbit the magnetic field over Siberia has
strengthened while it has weakened over Canada. The Canadian strong field
region has shrunk by 0.65% of Earthâ€Ös surface area, which is almost the
size of India, while the Siberian region has grown by 0.42% of Earthâ€Ös
surface area, which is comparable to the size of Greenland.
This shift, which is caused by complex processes going on in Earthâ€Ö
s
turbulent core, is associated with the northern magnetic pole moving
towards Siberia in recent years. This shift is important for navigation,
which is affected by the dance between these two areas of strong magnetic
field.
ESAâ€Ös Swarm Mission Manager, Anja Stromme, said, “Itâ€Ös really wonderful to
see the big picture of our dynamic Earth thanks to Swarmâ€Ös extended
timeseries. The satellites are all healthy and providing excellent data, so
we can hopefully extend that record beyond 2030, when the solar minimum
will allow more unprecedented insights into our planet.â€

Changes to AMSAT TLE Distribution for October 17, 2025
Two Line Elements or TLEs, often referred to as Keplerian elements or keps
in the amateur community, are the inputs to the SGP4 standard mathematical
model of spacecraft orbits used by most amateur tracking programs. Weekly
updates are completely adequate for most amateur satellites. TLE bulletin
files are updated daily in the first hour of the UTC day. New bulletin
files will be posted immediately after reliable elements become available
for new amateur satellites. More information may be found at
https://www.amsat.org/keplerian-elements-resources/
<https://www.amsat.org/keplerian-elements-resources/>.
This week there are no additions or deletions to the AMSAT TLE distribution
.

+ SpaceX closed a chapter in its Starship saga on October 13. It launched
what appeared to be a nearly flawless suborbital mission with its Version 2
Starship-Super Heavy rocket, the final flight for this iteration of the
launch vehicle. This was the final Starship launch of the year and the last
mission that will fly from Pad A in its current configuration. SpaceX now
turns its attention to completing and testing Version 3 of Starship-Super
Heavy, which will begin launch from Pad B. Itâ€Ös this iteration of t

will be laid off, according to an announcement made on the agencyâ€Ös website
on October 13. The news comes in the midst of an ongoing U.S. government
shutdown and the looming threat of the single largest funding reduction in
NASAâ€Ös 66-year history. Due to those potential cuts, NASA has been forced
to reshape many of its science and space exploration efforts. Scientists at
NASAâ€ÖS JPL oversee a fleet of flagship science missions designed to unravel
the mysteries of our solar system. They include the Psyche asteroid probe,

+ The Federal Communications Commission, which issues Amateur Radio
Service licenses, issued a Public Notice on Tuesday, September 30,
indicating that it would suspend most operations following a shutdown. ARRL
Volunteer Examiner Coordinator (ARRL VEC) Manager Maria Somma, AB1FM, said
the FCC systems appeared to go off-line around 1 PM Eastern time on
Wednesday, and are redirecting to the Public Notice. This means the FCC
will not be processing any amateur radio license applications during the
shutdown, which includes individual, club, and exam session (new and
upgrade) applications. However, Somma urged that Volunteer Examiners
continue to promptly forward session results from their exams to the ARRL
VEC. ARRL VEC will promptly resume submitting applications to the FCC for
processing. *(ANS thanks ARRL for the above information.)*
+ A constellation of classified defense satellites built by SpaceX is
emitting a mysterious signal that may violate international standards.
Satellites associated with the Starshield satellite network appear to be
transmitting to the Earth on frequencies normally used for sending commands
from Earth to satellites in space. The use of those frequencies to
“downlink†data runs counter to standards set by the International
Telecommunication Union. Starshieldâ€Ös unusual transmissions have the
potential to interfere with other scientific and commercial satellites,
warns Scott Tilley, VA7LF, an amateur satellite tracker in Canada who first
spotted the signals. *(ANS thanks National Public Radio for the above
