India's Mars orbiter, Mangalyaan, has successfully inserted itself into Mars orbit. India becomes only the fourth space agency to successfully make it into Mars orbit, behind the Soviets, NASA, and the ESA. Remarkably, the entirety of India's Mangalyaan mission cost just 4.5 billion rupees -- or about $74 million. Compare this to NASA's own MAVEN Mars orbiter, which has a total mission cost of around $672 million. This was also India's first attempt to reach Mars orbit -- historically, only Europe's ESA made it to Mars on its first attempt.
