The term ‘space weather’ describes conditions in space, near Earth. It is a little like the weather here on Earth, but on a much bigger scale. Find out more about space weather through the links below.
Space weather can have a range of effects on spacecraft, satellites and aircraft. It can also affect communication systems on Earth, as well as transportation networks, pipelines and power grids.
These impacts are often very small, but could be larger if a severe space weather event happens. Find out more about the possible impacts of space weather through the links below.
A severe space weather event is what we call a “high impact, low probability” event. That means it’s not very likely to occur but, if it does, the impact could be large. Find out more about what risk is and how it’s defined, and the possible risk of a severe space weather event through the links below.
The ability to prepare for, respond to and recover from emergencies is described by the word “resilience”. Resilience includes understanding the level of risk, preparing and planning for emergencies, responding to and recovering from emergencies, and making society (including organisations, communities and businesses) better able to deal with shocks and emergencies.
