Summary
GSAT-12 launched on an Indian Space Research Organization PSLV XL from Satish Dhawan Space Centre First Launch Pad, Satish Dhawan Space Centre, India on July 15, 2011. It was Indian Space Research Organization's 34th launch, 2nd this year and humanity's 5,141st orbital launch attempt. It was the 2nd PSLV XL flight and the 1st this year. The payload was bound for Geostationary Transfer Orbit (GTO). GSAT-12, one of 2 catalogued objects, reached a 285 × 21,355 km orbit inclined 17.8°. 2 objects from this launch are catalogued, one of them a payload.
