Chandrayaan-3 mission: What is the role of ISTRAC and MOX?

The ISTRAC centre provides telemetry, tracking and command services from the time a rocket launches with a satellite or spacecraft to injection of the satellite into orbit and through the lifespan of the satellite.

ISTRAC has a network of ground stations at Bengaluru, Lucknow, Mauritius, Sriharikota, Port Blair, Thiruvananthapuram, Brunei and Biak (Indonesia) and Deep Space Network stations.

ISTRAC is the location of the mission operations centre for ISRO deep space missions like Mangalyaan to Mars and Chandrayaan 1, 2 and 3 to the moon. ISTRAC will receive data from the spacecraft and communicate commands to it.

ISTRAC is networked with a Deep Space Network established outside Bengaluru for Isro’s deep space mission and will also be linked to ground stations of the Jet Propulsion Laboratory of the US and the European Space Agency for Chandrayaan-3.

The Mission Operations Centre or MOX

MOX consists of a Mission Control Room and a Mission Analysis Room which monitor a spacecraft 24×7. There are two MOX complexes at ISTRAC.

Since the launch of the Chandrayaan-3, the health and other flight parameters of the spacecraft have been controlled from MOX. The MOX facilities were first set up at ISTRAC for the Chandrayaan-1 fly-by-the-moon mission in 2008.

MOX can accommodate over 100 scientists to monitor a spacecraft. MOX resembles an operation theatre, with scientists seated on either side of a gallery poring over streams of data from a spacecraft.

Spacecraft are monitored for over 1,000 parameters to assess their overall health.
