Scientists and engineers at the Indian Space Research Organisation, or ISRO, are analysing whether its smallest rocket, SSLV-D1 - which experienced data loss in the final phase - was able to inject the two satellites onboard into a stable orbit. The preliminary finding on the status of the mission should be available in "few hours", Dr Madhavan Nair, ex-ISRO chief, told NDTV, calling the mission a complex.
