“Almost unknown to the public, a constellation of satellite guardians is flying overhead, and all it takes is a phone call for them to intervene when a country is hit by a storm, earthquake, tsunami or flood. Their cooperation comes under an agreement called the International Charter Space and Major Disasters. When catastrophe strikes, an ‘authorised user’ of the Charter simply phones a number at the European Space Agency (ESA), where space technicians are on round-the-clock duty. One of the 41 authorised users of the Charter is the United Nations, which can activate it on behalf of member states.”
