ON September 24, 2014 when the Mangalyaan spacecraft was inserted into Martian orbit as planned, with Prime Minister Modi present at ISRO’s Mission Control Centre in Bangalore, ISRO declared its maiden interplanetary mission, the Mars Orbiter Mission (MOM), a complete success. The Liquid Fuel Engine was fired at the right time as programmed, and the spacecraft was slowed down sufficiently to enable Mars to “capture” it within its orbit.
