ISRO's PSLV Successfully Launches IRNSS-1I Navigation Satellite from Sriharikota Days after Big Jolt

The Indian Space Research Organization (ISRO) launched the PSL V0C41/IRNSS-1I on Thursday from Satish Shawan Space Centre SHAR in Sriharikota. IRNSS-1I is an eighth navigation satellite to be a part of a constellation launched by ISRO. The PSL V0C41/IRNSS-1I mission satellite lifted off early in the morning at 04:04 am on Thursday. Congratulating ISRO over the successful launch, Prime Minister Narendra Modi said, “Congratulations to our scientists over the successful launch of navigation satellite. The launch will definitely bring benefits of our space program to the common man. Proud of team”. This was the second attempt by ISRO to send a replacement satellite. Notably, the preceding mission of a PSLV by ISRO carrying IRNSS-1H failed last year in August when the heat shield covering the satellite failed to separate. This also comes right two weeks after the launch of GSAT-6A on board GSLV MK-II, but, when the rocket placed GSAT-6A in orbit, ISRO lost connect with the satellite. IRNSS-1I is the 8th navigation satellite to join Indian Regional Navigation Satellite System (IRNSS) space segment. Previous satellites in the segment includes IRNSS-1A, 1B, 1C, 1D, 1E, 1F, and 1G launched by PSLV-C22 in July 2013, PSLV-C24 in April 2014, PSLV-C26 in October 2014, PSLV-C27 in March 2015, PSLV-C31 in January 2016, PSLV-C32 in March 2016, and PSLV-C33 in April 2016, respectively. IRNSS-1I has a lift-off mass of 1425 kg and the configuration is similar to IRNSS-1A, 1B, 1C, 1D, 1E, 1F, and 1G.
