❓ Frequently Asked Questions
What is space weather?
Space weather describes changes in the space environment caused by the Sun—such as solar flares, solar energetic particles, and geomagnetic storms—that can affect satellites, GPS, and high-altitude aviation.
How can solar flares and coronal mass ejections affect spacecraft?
They can damage or upset satellite electronics, degrade solar panels, and create radiation hazards or single-event upsets in onboard systems.
Why does space weather matter for aviation?
High-energy particles during solar storms increase radiation exposure for crews and passengers on high-altitude, high-latitude flights and can disrupt radio and GPS signals.
What is a geomagnetic storm?
A geomagnetic storm is a disturbance in Earth's magnetosphere caused by solar wind and eruptions, producing magnetic field fluctuations that can affect satellites, navigation, and power systems.
How is space weather managed in practice?
Forecasts from space weather agencies guide operations; operators may adjust spacecraft orientation or mission plans, reroute flights, and use radiation-hardened equipment and communication redundancies.
