Talking to reporters here, former ISRO scientist N Sivasubramaniam said, "Now our PSLV is carrying 1.25 tonne to 1.5 tonne capacity. Technically, we can say the capacity of rockets being launched can increase if we establish PSLN somehere in Kulasekarapattinam or in Kanyakumari as these places were close to the Equator. It could carry up to two tonne.
