War in space is no longer science fiction

THE FIRST shot of the next war between the world’s big powers, it is often said, will be fired in space. As conflict spreads on Earth, ill omens are emerging in the firmament. As countries race to develop new capabilities in space, some are also building the forces and weapons to fight beyond the atmosphere. On January 28th Iran said it had launched three satellites; Western countries fear they could be used in its ballistic-missile programme. Russia’s has opened a new chapter in space war. But America’s biggest dread is China, which seeks to America’s primacy in the heavens. Admiral Christopher Grady, vice-chairman of America’s joint chiefs of staff, explains it bluntly: “Space has emerged as our most essential warfighting domain.”
