Most people are familiar with the U.S. version of the space shuttle, the reusable spacecraft with the iconic white-and-black paint job. But did you know that the Soviet Union had a space shuttle, too?
When the Soviets caught wind of the American's shuttle program in the 1970s, they worried that the new vehicle was intended to bring the arms race to space. In true Cold War fashion, they began stealing American research for the craft, which, surprisingly, wasn't classified. By the 1980s, however, the Reagan administration made it harder to obtain, so the Soviets then turned to hacking early government, university and commercial computer databases. It was one of the first examples of online espionage [source: Windrem].
The Soviets' secret spy program led to the development of their own shuttle, Buran. Despite a nearly identical appearance to the U.S. space shuttle, Buranhad some key differences that some experts believe made it better. Although none of its engines were reusable (unlike the American craft, which had three engines built into its tail), Buran had a superior rocket system capable of carrying an astonishing 95 tons (86 metric tons) of cargo compared to the space shuttle's 29-ton (26-metric-ton) capacity. It was even capable of flying completely by remote control [source: Zak, "Better Space Shuttle"].
So if Buran was so great, what happened to it? Well, the shuttle didn't make its first flight until 1988, a time of great political turmoil in the Soviet Union, which ultimately collapsed in 1991. Russian President Boris Yeltsin canceled the program in 1993 before it ever took a second flight [source: Handwerk].
