As we discover more about the brilliant scale and nature of the Universe, planet Earth’s blue oceans, green forests and glistening city lights appear even more unique, and even more fragile.
Many hazards have been identified originating in space, which although unlikely, continue to pose real dangers to our way of life, and in the worst cases to human health and safety.
Only in the past decades have we had the opportunity to understand the potential perils of our position in our Solar System, and as technologies continue to advance we are entering a period in which we can actually act.
However, as technologies advance, so too does our dependence on them, making us more vulnerable to both human-made and natural threats in space.
