With the fall of the Soviet Union in 1991, the space race didn’t really end, but it definitely changed. The 1990s ushered in an era of cooperation not just between the United States and Russia, but included the many other space agencies that had been created around the world in the preceding decades.
Space exploration is mostly a multinational effort today. Space agencies regularly discuss and share information with the intent of accelerating space exploration. While bilateral space exploration was more typical during the second half of the 20th century, multinational partnerships are the wave of the future.
