Space officials say early investigation into a fire that tore through India's main space centre rules out sabotage.
Indian Space Research Organisation head Madhavan Nair ordered the probe after six people died on the island space centre in the state of Andhra Pradesh.
Sriharikota centre assembles and tests rockets and has a satellite launch pad used by several countries.
Isro officials say a building in the centre was severely damaged and repairs would take up to five months.
We will have a short-term delay, but not a major impact

"Initial estimates indicate the damage is nearly seven million rupees ($155,000)," Isro official Rajiv Lochan was quoted as saying by the AFP news agency.
But Mr Nair, who rushed to the centre late on Monday night, said no space programmes would be affected.
"Programmatically it may not have an impact, but we have to find out the reason for this occurrence and fix it," he told Indian television.
Another official said rocket tests would be carried out at an identical facility within the centre.
Explosion
Mr Nair has appointed a seven member team of serving and retired scientists to examine the cause of the blaze and submit its findings within six weeks.
Reports say an explosion triggered the fire at a solid propellant plant, where advanced rocket fuel is prepared.
"It looks to be a fire accident in which one of the motor segments which is being prepared for test... caught fire inadvertently," Mr Nair told All India Radio.
But correspondents say few details of the accident at the highly guarded space facility were being made public.
The Satish Dhawan Space Centre at Sriharikota is Isro's main launch base.
It is situated 100 kilometres (60 miles) from the city of Madras. The centre was built in 1971.
Several craft carrying telecommunications and imaging satellites for a number of countries have been put into orbit from the site.
Last year the government announced plans for an unmanned flight to the Moon, probably in 2008. The project is estimated to cost 3.5bn rupees ($74m).
