10. Satellites at Risk: How Space Technology Could Be Hit
Satellites orbiting Earth are among the most vulnerable targets during a solar storm.
High-energy particles can interfere with onboard electronics, sensors, and communication systems.
Specific Threats to Satellites:
- Surface Charging: Build-up of static electricity on a satellite’s surface can lead to damaging discharges.
- Internal Charging: Energetic particles penetrate into satellite electronics, potentially causing short-circuits.
- Solar Panel Degradation: Increased radiation can permanently reduce solar panel efficiency.
- Increased Drag: Atmospheric expansion during a storm can cause low-orbiting satellites to lose altitude faster, shortening their lifespans.
Many satellites have limited shielding to minimize weight and launch costs, making them ill-equipped to handle extreme geomagnetic activity.
Government agencies like NASA and private companies like SpaceX are monitoring the situation closely, preparing to put vulnerable satellites into safe modes when necessary.
11. Effects on Air Travel and Astronauts

Air travel and human spaceflight operations are also at risk during intense solar storms.
Air Travel Impacts:
- Disruptions to high-frequency radio communications, particularly near the polar regions.
- Navigation systems depending on GPS could become unreliable.
- Flight routes over the poles may need to be re-routed to maintain communication, leading to delays and increased fuel costs.
Effects on Astronauts:
- Astronauts aboard the International Space Station (ISS) face increased radiation exposure during solar events.
- They may be directed to shielded sections of the ISS during peak particle events.
- Future missions to the Moon and Mars must incorporate even greater radiation protection measures.
Both commercial airlines and space agencies have emergency protocols ready, but major events could still pose significant operational challenges.
12. Financial Systems and the Internet: A New Kind of Vulnerability
Today’s financial systems are highly dependent on satellites and instantaneous digital communication.
A strong enough solar storm could trigger serious financial consequences.
Potential Risks:
- Banking Network Failures: Communication disruptions could prevent banks from processing transactions.
- Stock Market Chaos: Automated trading systems rely on precise, continuous data feeds that could be interrupted.
- Internet Outages: Submarine cables carry power amplifiers vulnerable to geomagnetic disruptions.
While fiber-optic cables are immune to electromagnetic pulses, their electronics are not. - Blockchain and Cryptocurrency Networks: Digital assets could face major vulnerabilities due to synchronization failures.
A few hours of disruption would cost the world economy billions. A few days could cause a recession-level event.
This scenario underlines the urgency for financial institutions to develop space weather contingency plans.
