ISRO: PSLV-C37, PSLV-C38, PSLV-C36, GSAT-18, Know all about space agency's recent launches

The Indian Space Research Organisation's (ISRO) launch of India’s eighth private navigation satellite ‘IRNSS-1H’ on Thursday was unsuccessful. ISRO chief Kiran Kumar said that the heat shield failed to separate during the launch.

The 1425-kg satellite was expected to expand the existing seven satellites of the NavIC constellation. The launch vehicle PSLV-C39 lifted the satellite on Thursday using the 'XL' variant, of PSLV equipped with six strap-ons, each carrying 12 tons of propellant.

The three phases of the launch went smoothly, but unfortunately, the payload supposed to be separated at the start of the fourth phase could not be detached.
