As Indian Space Research Organisation (ISRO) tried to launch its eighth and most ambitious satellite - IRNSS-1H, on Thursday, the was declared unsuccessful as the rocket heat shield didn't separate.

Indian Space Research Organisation (ISRO) Chairman A.S. Kiran Kumar said: "The mission was unsuccessful."

Addressing a press conference after the launch failure, the chairman said,  "The rocket heat shield didn't separate. The satellite is inside the heat shield."

"The satellite was seen rotating inside the heat shield enclosure," he said.

Queried about the impact of the mission failure on getting commercial launch prospects, the ISRO Chairman said the issue has to be studied. 

The rocket's heat shield should have separated some three minutes into the launch, but it failed to. The scientists waited for some 19 minutes to see if it would separate, and then declared the mission unsuccessful. 

The IRNSS-1H satellite was expected to have been slung into orbit at around 507 km above the earth.

Rocket scientists are perplexed at the failure.

"It is really perplexing that such a thing has happened. Normally the PSLV rocket has several redundancies built into it," R.V. Perumal, a former ISRO scientist, he said.

ISRO also had earlier dismantled a fully assembled PSLV rocket to check a component in the rocket's second stage.
