The Powerhouse of ISRO, M Sankaran expertise in making novel power systems and solar arrays that go on to power satellites. With over three decades of experience in making satellites, his signature was present on Chandrayaan-1, Mangalyaan and Chandrayaan-2 satellites. It was his job to make sure the Chandrayaan-3 satellite was adequately hot and cold-tested and he helped create a lunar surface replica to test the strength of the lander.

The team also has a specialist on liquid propulsion engines, V Narayanan who is the director of the Liquid Propulsion Systems Center. Under his leadership, only the  Vikram lander will attempt the soft landing on the thrusters. His personal stamp is on most rockets made by ISRO, including the Launch Vehicle Mark 3, which launched Chandrayaan-3.

India has sent Chandrayaan-3 at the moon and its dancing there, thanks to masterminds like BN Ramakrishna who is the Director, ISRO Telemetry Tracking and Command Network and the commands sent by his institution.  India's largest dish antenna, a humongous 32-meter diameter dish situated outside Bengaluru, is being used to send commands to the Vikram lander. The final `twenty minutes of terror' will be witnessed from a flying saucer shaped building at ISTRAC.
