Sometime in late October or mid November when India sends its spacecraft off to Mars, its scientists will log the farewell event from the decks of two ships that will be positioned a hemisphere away in the South Pacific. The ships are slated to leave for their mission from Visakhapatnam on September 15. The Indian Space Research Organisation (ISRO) has leased the ships from the Shipping Corporation of India to study the crucial period when the PSLV rocket ejects the satellite into space. The fourth and last stage, which puts the satellite in space, was all‐important in a PSLV launch and had to be recorded. A team of a dozen ISRO’s satellite communication‐navigation experts will go on the ship‐borne study over the next three months, as also a few naval personnel.
