Elon Musk has warned that humanity is completely unprepared for the giant solar flares heading our way.
With our increased reliance on technology and satellites,
increased solar activity is a massive threat to our daily lives if we do not learn to manage it now.
But what exactly can solar flares do? What can we do to manage the situation?
Elon Musk has the answers.
An expensive storm.
SpaceX has over 3,000 satellites in orbit with plans to build a sprawling Starlink satellite network with 40,000 satellites.
In line with that objective, 49 satellites were sent to low orbit aboard the Falcon 9 on February 3rd,
only to come crashing down a week later.
Around the same time, a wave of solar radiation and energy particles washed over our planet due to an explosion on the surface of the Sun.
These eruptions, called coronal mass ejections or solar flares, reached Earth,
heating up the atmosphere in the process and raising the density of the small amounts of air
at an altitude of 130 miles where the Starlink satellites were sent.
Elon Musk released a statement explaining that the satellites were affected by a geomagnetic storm.
40 out of the 49 Starlink satellites were destroyed, effectively sending $50 million down the drain.
Starlink satellites and other low-orbit satellites are especially vulnerable to geomagnetic storms
since they are released into very low-altitude orbits and rely on onboard engines to overcome the force of atmospheric drag.
The geomagnetic storm caused the atmospheric drag to increase by 50%,
and this increase prevented the satellites from reaching higher orbits.
Since they could not bear the drag, they fell back to Earth.
The Starlink team tried to put the satellites in safe mode, but this effort was a little too late
as the storm prevented 80% of the satellites from reaching their destination.
The good news is the satellites' re-entry into Earth's atmosphere posed no collision risk to other satellites,
and no part hit the ground.
Additionally, a fresh set of satellites were launched on the Falcon 9 earlier this month
and were placed at a higher orbit to avoid atmospheric influences contributing to another fall.
But Starlink satellites were not the only systems affected by the increase in solar activity this year.
An active sunspot about to leave the visible disk of the Sun shot a parting solar flare at Earth,
disrupting shortwave radio communications in the Middle East and Africa.
This occurred on September 16, affecting frequencies below 25 MHz.
Space weather forecasters at the UK Met Office predict more flares from the lively sunspot AR3089
and believe that a coronal mass ejection might be heading to Earth as well following the flare.
While this geomagnetic storm was small, Musk noted that we are far from ready to deal with
more serious solar flares and geomagnetic storms that can have an impact on our everyday lives.
Solar flares are huge explosions on the surface of the Sun, emitting electromagnetic radiations
like radio waves, X-rays, ultraviolet radiation, and visible light.
Imagine a million volcanoes exploding at the same time.
These flares occur when built-up magnetic energy in the solar atmosphere is released suddenly.
They tend to occur from cooler regions of the Sun, called sunspots,
and are intricately tied to the 11-year cycle of solar activity driven by the Sun's magnetic field.
These solar flares are grouped into classes depending on the intensity of the explosion.
Ranging from weakest to strongest, the categories are A, B, C, M, and X.
The geomagnetic storm responsible for the Starlink satellites is a small G1 class
caused by an M1-class solar flare. Another X1 flare, the most intense of them all,
was spotted by NASA's Solar Dynamics Observatory on October 2nd,
and this X-class flare might have disrupted Hurricane Ian disaster response,
affecting rescue workers using 25 MHz radios to communicate.
Effects of Solar Flares on Earth
The first geomagnetic storm in recorded history was identified by British astronomer Richard
Carrington in 1859. Carrington was investigating a group of sunspots and spotted a beam of light
that lasted five minutes. The subsequent geomagnetic storm resulted in auroras visible
from the northern hemisphere to as far south as the Caribbean. The glow from the auroras was
enough to make miners believe that morning had come. People in the northern hemisphere
in the United States could read newspapers with the aurora's light. As the colorful lights dazzled
many, the geomagnetic storm caused telegraph systems all over Europe and North America to fall.
Spark flew from the telegraph machines, and operators received severe shocks whenever
they tried to use it. Despite the batteries being down and the machines disconnected,
some telegraph lines from New York to Pittsburgh could send messages due to the electricity in the
air. Called the Carrington event, this was the most intense solar flare to occur in the previous
500 years, and if it happened today with the technology we have in place, it would affect
whole continents, and its effects would be felt for years. This was emphasized by researchers
from the Atmospheric and Environmental Research Agency, saying that such an event today would
result in close to $2 trillion in damages. But before that happens, make sure you hit

aurora, powerful storms can do much more, like taking down satellites in their entirety.
It can also throw out our ability to accurately predict the positions of objects in low-Earth
orbit. Using radar measurement, the Space Surveillance Network tracks down the location
of defunct spacecrafts and debris, ensuring that satellite operators like SpaceX receive
timely warnings when their satellites are in proximity of space debris. But this cannot
happen during a powerful solar storm. According to solar physicist and director of the Space
Weather Technology Center at the University of Colorado, Tom Berger, in the largest storms,
the errors in the orbital trajectories become so large that essentially the catalog of orbital
objects is invalidated. Objects can end up kilometers away from their initial location,
and may remain lost until they are found again using radar. Most people are gradually becoming
aware of this phenomenon, but the Earth is no stranger to the sun's wrath. In 1972,
a major solar flare knocked out long-distance phone communication across several states,
causing AT&T to redesign its power system for transatlantic cables. In Canada, 6 million people
were left without electricity for nine hours due to a geomagnetic storm. The solar storms of 2003,
now dubbed the Halloween storms of 2003, caused aircraft to be rerouted, affected satellite
systems, and caused power outages in Sweden. The current solar cycle, Cycle 25, is intensifying as
it approaches its peak in the next one to two years, and scientists are warning that this could
be the most active one since record-keeping started in the 1700s. This is what it means for
us. The sun's activity in solar events will increase between 2023 to 2025 and will affect
the technology here on Earth, our communication systems, as well as the satellites and astronauts
in space. Electric power grids and national systems will be disrupted. The impending solar
storms and space weather will drive intense electric currents, causing damage to important
infrastructure, expensive power outages, and high costs of repair and maintenance.
During this time, near-polar regions might experience high fluxes of radiation in the
These particles can travel to low altitudes and may become a source of concern for airplane
flight crew and passenger health. The only upside to the current Cycle 25 is the impressive
auroral displays we'll get to see. But is there a way we can manage it? Elon Musk believes there is.
To manage the situation ahead of time and avoid costly events, Elon advises that we start by
While it is possible for scientists to monitor solar activity from afar with a telescope
and determine which solar flares and coronal mass ejections would pose a threat,
that wouldn't be sufficient for the task at hand. Inside of this,
NASA is developing a mission that will provide critical advances in our understanding of solar
flares and the ionosphere-thermosphere system. This mission will provide the first coordinated
where the effects of solar activity are often seen. When this mission is complete,
it will drastically increase our understanding of solar activity and aid improvements in our
current space weather models. So when solar activity reaches its peak, as the current
solar cycle comes to an end, its negative effects on our ground-based, air-based,
and space-based assets will be mitigated. The Earth's insulating atmosphere and magnetic field
protects us from feeling the full impact of even the most powerful solar outbursts.
Even though it can bring down satellites and mess with our power systems,
most of the harmful effects are stopped in the sky long before it touches human skin.
Even the strongest solar events have not been strong enough to destroy the Earth's atmosphere.
The present goal is to build on existing systems in order to monitor the magnetic fields of charged
particles moving from the Sun to the Earth, so we would not be caught unaware by massive solar
storms. Can scientists find a way to overcome the effects of solar flares and geomagnetic storms?
