We're arguably closer than ever to war in space. Most satellites orbiting Earth belong to the U.S., China and Russia. And recent tests of anti-satellite weapons don't exactly ease the scare factor. (Video via NASA)

It sounds like science fiction, but the potential for real-life star wars is real enough. It's just not new. (Video via Walt Disney Studios Motion Pictures / "Star Wars: Episode VII - The Force Awakens)

Fears of battles in space go back to the Cold War and several initiatives, like President Reagan's "Star Wars" missile-defense system. (Video via ABC) 

Deputy Defense Secretary Robert Work spoke to Congress in June about the threat. He said during a speech the technology the U.S. developed during the Cold War allows it "to project more power, more precisely, more swiftly, at less cost."

President Obama requested $5 billion for space defense in the 2016 fiscal budget.

And a former Air Force officer told the Scientific American most of the U.S.' capabilities in space have been declassified to send a clear message: There are no rules for war in space.
