ISRO’s IRNSS 1H satellite launch fails, agency to analyse

ISRO’s IRNSS 1H satellite launch fails, agency to analyse-It was not ISRO’s Day, On Thursday, The launch of India’s latest navigational satellite IRNSS 1H has failed. India’s Polar Satellite Launch Vehicle (PSLV) C-39, carrying IRNSS-1H navigation satellite system NavIC (Navigation with Indian Constellation) failed due to a technical glitches.

This was the first failure of Polar Satellite Launch Vehicle after 39 successful launches in a row. NavIC will reduce India’s dependency on foreign satellites for GPS data. IRNSS-1H also known for backup satellite for all the 7 Satellites of IRNSS series.

India’s Polar Satellite Launch Vehicle (PSLV) C-39 with IRNSS-1H navigation satellite lifted off from the Satish Dhawan Space Centre, in Sriharikota, on August 31, 2017.

The launch fails when the satellite’s fourth stage did not go as planned. PSLV C-39 had lifted off successfully from the space centre in Sriharikota but after nearly 20 minutes due to a technical glitch, it fails in the fourth stage of launch.

The first three stages of the satellite launch were completed as successfully, and And the mission was on its way to succeed till technical problem occurred.

ISRO Chief AS Kumar explained the process and said that “A heat shield is used to protect the satellite. It has to separate and fall out in the fourth stage. And once it happens, the satellite is ready to release to get into the orbit.” But this didn’t happened as planned, he added.

Initially it was reported that mission was not successful as heat shield was not separated as planned.

Another ISRO official told that The heat shield is used to protect the satellite during its atmospheric phase change.

Addressing media after the failed launch, Kumar said it was fortunate that the PSLV-C39 had only one satellite on board.

A successful launch would have ushered a new era in the country’s history of space exploration as, For the first time, the private sector has been actively involved in assembling and testing of a satellite unlike earlier where its role was limited to supplying components.

Indian Space Research Organisation (ISRO) chief AS Kiran Kumar said that the eighth navigational satellite to be launched, was unsuccessful and said further analysis would be carried out.

The Indian Regional Navigation Satellite System (IRNSS) is an independent regional navigation satellite system developed by India. It works in same way as US-based GPS works. Each successful launch of IRNSS mission will reduce India’s dependency on other countries.

In this mission ISRO had earlier launched seven satellites: IRNSS-1A on July 1, 2013, IRNSS-1B on April 4, 2014, IRNSS-1C on October 16, 2014, IRNSS-1D on March 28, 2015, IRNSS-1E on January 20, 2016, IRNSS-1F on March 10, 2016 and the last and latest one was IRNSS-1G which was launched on April 28, 2016.

With this navigational system, India will become a part of the elite group of countries that have their own navigational systems including the USA, Russia, China and Europe.
