Since 1960, humanity launched dozens of missions to Mars to learn more about our planetary neighbor. Mars appears to be a world once rich in water and perhaps, in life, presenting an interesting counterpart to Earth.

Since the first successful flyby in 1965, four space agencies have successfully made it to Mars: NASA, the former Soviet Union space program, the European Space Agency and the Indian Space Research Organization, while others, including the space agencies in Russia, Japan and China, have attempted Mars or Martian moon missions without success.
