Indian Deep Space Network 
The Indian Space Research Organisation (ISRO) set up a Deep Space Network (DSN) centre in Byalalu. One of the main advantages of having the DSN at Byalalu was its saucer-like shape that would help in blocking radio frequency disturbances. The DSN was initially set up to track Chandrayaan I, India's first lunar mission; as of September 2014, it is being used to track the ongoing Mars Orbiter Mission (MOM), known as Mangalyaan.
