(Contd.)

If PSLV-C60/SpaDeX launches as scheduled from FLP, it will be the shortest period between two consecutive orbital launches for ISRO from same pad at 25.25 days after PSLV-C59/PROBA-3 launch on 5 December.

Previous shortest gap was 31.02 days between GSLV-F09/GSAT-9 and GSLV MkIII-D1/GSAT-19 from SLP.
