Space Forces refer to military organizations specifically tasked with operations in outer space. Their primary responsibilities include protecting national interests in space, monitoring satellite activities, and ensuring the security of space assets. These forces may also engage in research and development of technologies related to space defense. Countries like the United States have established dedicated branches, such as the United States Space Force, to address the growing importance of space in national security. Other nations are also developing their own space military capabilities, recognizing the strategic significance of space in modern warfare and global communications.
