The FCC approved 7,500 more Starlink satellites, bringing the constellation to about 15,000 by 2031, but scientists warn this could heighten collision risk in crowded orbits, trigger space-debris concerns (including sub-10 cm fragments), and alter the stratosphere with more aluminum oxide from deorbiting, while solar storms pose additional lower-orbit risks—even as officials emphasize faster broadband and economic benefits.
A new study warns that the increasing density of satellite mega-constellations in Low Earth Orbit creates a fragile system at risk of catastrophic collision, especially during solar storms, with potential for a rapid cascade of debris and loss of space access within days if control is lost. The paper emphasizes the urgent need for better management and risk assessment to prevent a future space debris catastrophe.
Space weather forecasters warn of severe solar storms caused by recent coronal mass ejections from the sun, which could produce vibrant northern lights visible across much of the northern U.S. and disrupt communications, GPS, and power grids. The sun is currently at the peak of its 11-year activity cycle, increasing aurora activity and space weather events, with experts advising caution and preparation for potential disruptions.
The northern lights may be visible in Utah on Tuesday and Wednesday nights due to solar storms, with the best viewing chances on Tuesday from 8 p.m. to 11 p.m., though cloud cover could hinder visibility. The aurora borealis has been increasingly visible in Utah since 2023, and residents are encouraged to watch social media for updates and share their photos.
Space weather forecasters warn of severe solar storms caused by recent coronal mass ejections from the sun, which could produce spectacular auroras visible across much of the northern U.S. and even further south, while also potentially disrupting communications and power grids. The sun's heightened activity, part of its 11-year cycle, increases the likelihood of these displays and disruptions, with experts advising on how to view the auroras safely and effectively.
A study finds a correlation between increased geomagnetic activity during solar storms and higher rates of heart attacks, especially among women aged 31-60, suggesting space weather may influence cardiovascular events. The research highlights the need for further investigation to understand causality and potential preventive measures.
A trio of space weather satellites launched from Kennedy Space Center to study solar storms and improve forecasting, aiming to better protect astronauts and Earth from solar radiation, with full operation expected by early next year.
NOAA's first dedicated space weather observatory, SWFO-L1, was successfully launched into space aboard a SpaceX Falcon 9 and will travel to Lagrange point 1 to provide early warnings of solar events like CMEs, enhancing protection for critical infrastructure and national security, with operational status expected by mid-2026.
NASA is launching three satellites to study space weather and its effects on Earth, focusing on protecting critical infrastructure like GPS and power grids from solar storms, with the mission emphasizing astronaut safety and understanding solar activity's influence on our planet and the solar system.
Earth is experiencing significant solar storms, including a G3 geomagnetic storm, which are causing disruptions to power grids, satellite communications like Starlink, and creating opportunities to view the Northern Lights, especially in northern US states. The storms are expected to weaken by midweek, but ongoing effects and future impacts, particularly near the South Atlantic Anomaly, remain a concern.
A study suggests that gravitational tidal forces from Venus, Earth, and Jupiter may help keep the sun calmer than other stars, potentially reducing the risk of extreme solar storms that could disrupt Earth's technology. These forces influence the sun's magnetic activity in a cyclical manner, possibly explaining why our sun's eruptions are milder compared to similar stars, which may have contributed to Earth's habitability.
A new study warns that climate pollution is reducing Earth's upper atmospheric density, which, combined with solar-triggered geomagnetic storms, could significantly increase risks to GPS and communication satellites in the coming decades, potentially damaging satellite operations and increasing space junk.
NASA is launching two satellites as part of the TRACERS mission to study magnetic reconnection in Earth's magnetosphere, aiming to better understand and predict solar storms that can impact Earth's technological systems, including power grids and communication networks.
Solar storms caused by increased solar activity are shortening the lifespan of SpaceX's Starlink satellites by 10-12 days due to atmospheric drag, raising risks of satellite collisions, debris, and challenges in managing Earth's crowded orbit, necessitating improved space traffic strategies.
NASA is launching two satellites called TRACERS to study magnetic storms and space weather effects on Earth, aiming to improve prediction and protection against solar storms by understanding magnetic reconnection processes in Earth's magnetosphere.
