India has successfully placed a satellite named Mangalyaan into orbit around Mars:

Only the US, Europe and Russia have previously sent missions to Mars.

Mangalyaan is remarkable for its relatively low cost. The total cost of the Indian mission is estimated at $74m, compared with the current Maven mission at $671m. 

A key aim of the mission is to try to detect methane in the Martian atmosphere.

Comment: There may be some duplication of scientific results compared to other missions, but hopefully Mangalyaan will add to our knowledge of Mars.
