Summary
TES launched on an Indian Space Research Organization PSLV from Satish Dhawan Space Centre First Launch Pad, Satish Dhawan Space Centre, India on October 22, 2001. It was Indian Space Research Organization's 15th launch, 2nd this year and humanity's 4,502nd orbital launch attempt. It was the 6th PSLV flight and the 1st this year. The payload was bound for Sun-Synchronous Orbit (SSO). TES, one of 375 catalogued objects, reached a 559 × 586 km orbit inclined 97.8°. 375 objects from this launch are catalogued, 3 of them payloads.

About this launch
Technology Experiment Satellite (TES) is Indian remote sensing and photo-reconnaissance satellite. The 1108 kg satellite carries a one-meter resolution panchromatic camera is an experimental satellite to demonstrate and validate, in orbit, technologies that could be used in the future satellites of Indian Space Research Organisation (ISRO). It was successfully placed in 572 km Sun-synchronous orbit on 22 October 2001 using the PSLV-C3. The PSLV-C3 also injected two more satellites: PROBA, a Belgian satellite and BIRD, a German satellite.
