The Mars orbiter spacecraft, once it leaves the Sriharikota launch site on Tuesday afternoon, will be closely tracked by a network of about 10 ground stations round the globe besides two ship-based terminals that the Indian Space Research Organisation (ISRO) has deployed in the South Pacific.
The stations will monitor every detail of the different stages of the flight. They include the PSLV-C25's four-stage flight, its ejection of the satellite over the South Pacific, both of which will together last 43 minutes; the Earth-bound manoeuvres until November 30; and later the heliocentric phase of going half-way around Sun; and from then on until it reaches Mars after 300 days.
The launch takes place from the Satish Dhawan Space Centre in Sriharikota in coastal Andhra Pradesh.
Once the spacecraft is separated from the launcher, the control operations shift into the hands of Bangalore-based ISRO Telemetry, Tracking and Command Network (ISTRAC).
The ISTRAC's infrastructure includes the two-antenna Indian Deep Space Network to monitor the orbiter once it leaves the Earth's sphere of influence after November 30 and throughout its life.
