The scientists meeting to find out the causes of the failure of the GSLV-D3 mission have said that contrary to initial reports the indigenously built cryogenic engine did infinite during the third stage of the rocket when it entered the vacuum of space.

The scientists from Indian Space Research Organisation (ISRO) met at the Vikram Sarabhai Space Centre in Thiruvananthapuram to carry out post mission analysis. After the study of the third stage they found that the mission failed because fuel turbo pump which was supplying fuel to the engine stopped working a second after the engine ignited.

A senior scientist explained that they saw indications that rocket's acceleration had increased for a second before it started drifting from its patch just when it started the third stage.

ISRO will form a committee to find the exact reason for the failure of the mission. The report is expected by the end of May after which the national experts' panel will examine the report.

Dr. Radhakrishnan of ISRO is expected to meet the Prime Minister Manmohan Singh on Tuesday to explain the causes of the failure.
