India successfully launched the Mangalyaan satellite into orbit around Mars in 2014, joining NASA's MAVEN satellite. Mangalyaan was one of the most economical interplanetary missions ever undertaken, costing just 450 crore rupees compared to NASA's 3,950 crore rupee MAVEN mission. To keep costs low, India reused existing technologies and used a smaller rocket to first place the spacecraft into Earth's orbit before slingshotting it towards Mars. Mangalyaan aims to monitor Mars' weather, take color pictures of the surface, map the planet's mineral composition, and measure methane levels in the atmosphere.
