According to reports, the plane suddenly and sharply descended for no apparent reason while over Florida. Although the pilots quickly regained control of the aircraft, at least 15 passengers were injured, forcing the pilots to make an emergency landing at Tampa International Airport. Earlier this week, Airbus issued a statement attributing the incident to &#8220;intense solar radiation,&#8221; which could have corrupted &#8220;data critical to the operation of flight control systems.&#8221; The manufacturer subsequently grounded 6,000 A320 aircraft to release software updates to address the vulnerability.<\/span><\/p>\n\n<p style=\"text-align: justify;\"><span dir=\"auto\">But there&#8217;s a catch: solar radiation levels on October 30 were unremarkable and far from levels that would affect the aircraft&#8217;s electronics, said Clive Dyer, a space weather and radiation expert at the University of Surrey in the UK. Instead, Dyer, who has studied the effects of solar radiation on aircraft electronics for decades, believes the stricken plane&#8217;s onboard computer may have been hit by a cosmic ray\u2014a stream of high-energy particles from the explosion of a distant star that could travel millions of years before reaching Earth.<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">Cosmic rays can interact with modern microelectronics and alter the state of a circuit. They can cause a simple bit flip, for example, from 0 to 1 or from 1 to 0. They can distort information and lead to malfunctions. But they can also cause hardware failures by inducing current in an electronic device and rendering it inoperable.<\/span><\/p>\n<p style=\"text-align: justify;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4406\" src=\"https:\/\/planeta21vek.ru\/wp-content\/uploads\/2026\/09\/samolet010126.jpg\" sizes=\"auto, (max-width: 650px) 100vw, 650px\" srcset=\"https:\/\/planeta21vek.ru\/wp-content\/uploads\/2026\/09\/samolet010126.jpg 650w, https:\/\/planeta21vek.ru\/wp-content\/uploads\/2026\/09\/samolet010126-300x169.jpg 300w\" alt=\"\" width=\"650\" height=\"366\" \/><br \/>\n<em><span dir=\"auto\">In late October, a JetBlue Airbus A320 plunged into freefall, presumably due to exposure to cosmic rays. SOPA Images\/Getty Images<\/span><\/em><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">Cosmic rays often occur when massive stars explode in supernovas at the end of their lives. The explosions accelerate streams of protons, scattering them across the universe at the speed of light. Cosmic rays constantly impact the Earth&#8217;s atmosphere, interacting with air molecules and generating streams of exotic particles such as muons, high-energy neutrons, and positrons. When these particles fall to Earth, they can hit electronic circuits inside an aircraft sensor or onboard computer, causing what researchers call a single-point fault.<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">Solar flares, such as solar discharges, also generate such particles and can be tens of times, and in extreme cases thousands of times, more destructive than particles from cosmic ray showers. As the Sun becomes more active, incidents caused by isolated malfunctions in aircraft electronics may become more frequent.<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">In fact, less than two weeks after the JetBlue incident, potentially dangerous levels of solar radiation caused by a powerful solar flare persisted in the atmosphere at flight altitudes for several days. Therefore, Airbus&#8217;s software update makes sense, although, according to Dyer, solar activity could not have been the cause of the BlueJet accident.<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">For Dyer, the effects of cosmic radiation on spacecraft and aircraft electronics has been his life&#8217;s work. In the 1980s, he was part of a team that investigated isolated malfunctions in spacecraft and later used radiation monitors on board Concorde. He believes that isolated malfunctions in aircraft electronics caused by cosmic rays, while rare, are not unprecedented.<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">In fact, Dyer believes the 2008 Quantas Flight 72 incident was likely caused by a similar particle intrusion. The stricken aircraft, an Airbus A330, twice nosedived over the Pacific Ocean, creating brief periods of near-weightlessness. Unfortunately, the passengers were unprepared for the sudden release, and many suffered serious injuries.<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">Dyer, who was acting as a consultant to the investigation at the time, stated that although the incident was attributed to faulty electronic sensors on the aircraft, the investigation concluded without establishing a definitive cause. He believes that sunlight can significantly increase the level of particulate matter by a factor of a thousand.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #000080;\"><strong><span dir=\"auto\">The Met Office and the Department for Transport have published new guidance on how space weather can impact communications, navigation and other technologies used in the transport industry, to help operators understand the potential impacts and prepare for them.<\/span><\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">The guide combines the expertise of the Met Office&#8217;s Space Weather Prediction Centre with knowledge of the transport industry to help decision-makers understand how space weather impacts transport operations and use Met Office advisories to take appropriate action during space weather events. The guide covers the aviation, maritime, rail, and road transport sectors and includes case studies from recent space weather events.<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">Although severe disturbances are rare, space weather can impact transportation. The role of the 24\/7 space weather forecasting centers is to use their expertise to help people understand the risks and, crucially, take action to prevent the most severe impacts. This guide aims to dispel myths about the warnings and advisories issued by the Met Office and help key transportation operators obtain the information they need to make critical mitigation decisions.<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">The guide covers space weather terminology and notifications, as well as information on the potential impacts of events such as solar flares, geomagnetic storms, and solar radiation storms, broken down by transportation mode. Risks highlighted include disruption of high-frequency radio communications, GNSS\/GPS positioning errors, and, in the most severe cases, the possibility of localized power outages. Most space weather events have little impact on day-to-day transportation operations, but this guide is intended to help operators understand when they may experience impacts during periods of heightened activity.<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">Along with case studies of events in May 2024 and September 2017, the guide examines the Carrington Event of 1859, considered the most intense space weather event on record. Because society at the time relied much less on technology, the impacts were limited to compass errors, disruptions to telegraph services, fires caused by sparking telegraph lines, and auroras visible worldwide, including in tropical latitudes. Such extreme events are extremely rare, but the Carrington Event is used in planning as the most likely scenario for severe space weather impacts.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #000080;\"><strong><span dir=\"auto\">During solar storms, ISS astronauts shelter from radiation, while at the same time, solar storms trigger auroras across the planet.

Every time the Sun ejects a coronal mass ejection (CME)\u2014a burst of magnetized plasma\u2014at Earth, the planet&#8217;s tenuous upper atmosphere thickens. Satellites in low Earth orbit experience greater drag and slow down, meaning their trajectories become unpredictable.<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">For example, in 2003, after the Halloween Storm\u2014one of the most intense space weather events in the past three decades\u2014satellite operators lost track of their spacecraft for several days. At the time, several hundred active satellites were orbiting the planet, and no collision occurred. And the Halloween Storm was only a small fraction of what the Sun is capable of. A more powerful solar storm, perhaps as powerful as the Carrington Event of 1859\u2014the most intense solar storm recorded in recorded history\u2014would have taken a week or more to fully subside.<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">At the onset of a solar storm, the atmosphere&#8217;s density increases sharply, and objects begin to be pulled downward. Before everything begins to return to normal, uncertainties of several kilometers arise in satellite positions, making it impossible to estimate the objects&#8217; future locations, making it impossible to predict collisions and conduct evasive maneuvers.<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">Crash Clock data show that in 2018, near-Earth space would likely have recovered from the most extreme solar storm before the first collision. However, in 2025, an orbital collision would have been virtually inevitable. Such a collision would have created thousands of fragments that would have threatened everything in their path, potentially triggering an unstoppable chain of events. With each subsequent collision, the affected orbital region would have become increasingly dangerous\u2014a nightmare scenario known as Kessler syndrome.<\/span><\/p>\n<p style=\"text-align: justify;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4409\" src=\"https:\/\/planeta21vek.ru\/wp-content\/uploads\/2026\/09\/solnze0301262.jpg\" sizes=\"auto, (max-width: 650px) 100vw, 650px\" srcset=\"https:\/\/planeta21vek.ru\/wp-content\/uploads\/2026\/09\/solnze0301262.jpg 650w, https:\/\/planeta21vek.ru\/wp-content\/uploads\/2026\/09\/solnze0301262-300x169.jpg 300w\" alt=\"\" width=\"650\" height=\"366\" \/><br \/>\n<em><span dir=\"auto\">An artist&#8217;s illustration of space debris orbiting Earth.

Sunspot-affected areas are often associated with higher solar activity, such as solar flares, which are intense bursts of radiation, and coronal mass ejections, which are huge bubbles of plasma erupting from the Sun&#8217;s surface and spreading throughout the solar system.<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">NASA scientists monitor these space weather events because they can impact spacecraft, astronaut safety, radio communications, GPS, and even power grids on Earth. Space weather forecasts are crucial to the operation of spacecraft and astronauts during NASA&#8217;s Artemis mission, as understanding the space environment is vital to reducing astronauts&#8217; exposure to space radiation.<\/span><\/p>\n<p style=\"text-align: justify;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4413\" src=\"https:\/\/planeta21vek.ru\/wp-content\/uploads\/2026\/09\/solnze01012627.jpg\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" srcset=\"https:\/\/planeta21vek.ru\/wp-content\/uploads\/2026\/09\/solnze01012627.jpg 1000w, https:\/\/planeta21vek.ru\/wp-content\/uploads\/2026\/09\/solnze01012627-300x300.jpg 300w, https:\/\/planeta21vek.ru\/wp-content\/uploads\/2026\/09\/solnze01012627-150x150.jpg 150w, https:\/\/planeta21vek.ru\/wp-content\/uploads\/2026\/09\/solnze01012627-768x768.jpg 768w, https:\/\/planeta21vek.ru\/wp-content\/uploads\/2026\/09\/solnze01012627-80x80.jpg 80w, https:\/\/planeta21vek.ru\/wp-content\/uploads\/2026\/09\/solnze01012627-60x60.jpg 60w, https:\/\/planeta21vek.ru\/wp-content\/uploads\/2026\/09\/solnze01012627-120x120.jpg 120w\" alt=\"\" width=\"1000\" height=\"1000\" \/><br \/>\n<em><span dir=\"auto\">On September 9, 2025, NASA&#8217;s Solar Dynamics Observatory captured this image of the Sun.

As the solar wind\u2014a stream of charged particles emanating from the Sun\u2014and other solar activity intensify, the Sun&#8217;s influence expands and contracts magnetospheres, which serve as protective bubbles for planets with magnetic cores and magnetic fields, including Earth. These protective bubbles are important for protecting planets from plasma streams emanating from the Sun in the solar wind.<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">Over centuries of solar activity study, the quietest periods occurred during the seventy-year period from 1645 to 1715 and the four-decade period from 1790 to 1830. &#8220;We don&#8217;t really know why the Sun experienced the 40-year minimum that began in 1790,&#8221; Jasinski said. &#8220;Longer-term trends are much less predictable, and we don&#8217;t yet fully understand them.&#8221;<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">In the two and a half decades leading up to 2008, sunspot numbers and solar wind had declined so much that researchers expected the 2008 &#8220;deep solar minimum&#8221; to mark the beginning of a new period of historically low activity in the Sun&#8217;s recent history.<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">&#8220;But then the solar wind&#8217;s downward trend stopped, and since then the plasma and magnetic field parameters have been steadily increasing,&#8221; said Jasinski, who led the analysis of heliospheric data publicly available on the OMNIWeb Plus platform, run by NASA&#8217;s Goddard Space Flight Center in Greenbelt, Maryland.<\/span><\/p>\n<p style=\"text-align: justify;\"><span dir=\"auto\">The data Jasinski and his colleagues used for their study came from a wide range of NASA missions. Two primary sources\u2014Advanced Composition Explorer (ACE) and the Wind mission\u2014were launched in the 1990s and provide data on solar activity, such as plasma and energetic particles moving from the Sun to Earth. These spacecraft are part of a group of NASA&#8217;s Heliophysics Division missions designed to study the Sun&#8217;s influence on space, Earth, and other planets.<\/span><\/p>\n<a target=\"_blank\" rel=\"nofollow\" href=\"https:\/\/planeta21vek.ru\/eng\/go\/41\"  class=\"su-button su-button-style-flat su-button-wide\" style=\"color:#FFFFFF;background-color:#af170f;border-color:#8c130c;border-radius:5px;-moz-border-radius:5px;-webkit-border-radius:5px\" target=\"_blank\" rel=\"noopener noreferrer\"><span style=\"color:#FFFFFF;padding:7px 22px;font-size:17px;line-height:26px;border-color:#c75d57;border-radius:5px;-moz-border-radius:5px;-webkit-border-radius:5px;text-shadow:none;-moz-text-shadow:none;-webkit-text-shadow:none\"><i class=\"sui sui-heart\" style=\"font-size:17px;color:#FFFFFF\"><\/i> Comment on Facebook* The owner of the Meta company is recognized as extremist in Russia and is banned.<\/span><\/a>\n\n","protected":false},"excerpt":{"rendered":"<p>The effects of solar storms may be limitless.
