భార‌త్‌- అమెరికా సంయుక్తంగా నిసార్ అనే శ‌క్తివంత‌మైన శాటిలైట్‌ను నింగిలోకి పంపింది. భూగోళాన్ని పరిశీలించేందుకు తొలిసారిగా ఈ ఉపగ్రహాన్ని ప్రయోగించారు. ఆంధ్రప్రదేశ్ లోని శ్రీహరికోట సతీష్ ధావన్ అంతరిక్ష పరిశోధన కేంద్రం (SDSC SHAR) నుంచి ఈ ప్ర‌యోగం చేపట్టారు. ఇస్రోకి చెందిన GSLV రాకెట్ ద్వారా రాకెట్‌ను ప్ర‌యోగించారు.

00:18All L-40 engines generating nominal thrust. S-139 motor excited.
00:22That's the memory of the GSLV F-16 nice car mission. The deafening roar of GSLV and beautiful silhouette brightening the Sriharikota sky.
00:35The first stage of GSLV with S-139 solid co-motor and four L-40 electric motors.
00:57The first stage of GSLV with S-139 solid co-motor and four L-40 liquid strap-ons thrusting together. 7,800 kilonewton cumulative thrust.
01:12The day of launch wind biasing program that is fed into the onboard computers.
01:20Head the rocket to near to the atmosphere with minimal aerodynamic loads.
01:24Pratam Charan ka core booster lag-bag 100 secs tok prajolet rahe ga.
01:31Tathha L-40 Charan, 150 second tuk prajolet rahe ga.

01:53shower ground station is tracking
01:57yes 139 burnout
02:10core booster ka prajolansamato ho chuka hai
02:15here we have an announcement from the range operations director
02:19that the core booster has stopped its operation the four L-40s are thrusting
02:25still
02:28first stage performance normal
02:34pratham charan ka karin ashfadhan puri tarah saamanya yaan udhishth disha ki
02:38o ragrasar hota hua vartaman mein pratham charan prajolit hai L-40s
02:43prajolit hai in ka kul karyakal 150 second ka ho ga

02:58IS 1x2 main separated
03:00the payload fairing has also been separated and closed-loop guidance
03:05has been initiated
03:15the GS1 has undergone a hot separation and GS2 commenced its operation and thrusting nominally
03:22the payload fairing has also been separated and closed-loop guidance has been initiated
03:29the payload fairing has also been separated and closed-loop guidance has been initiated
03:34in the second stage performance normal
03:37the power and se bahar ja chuka hai is liye
03:39payload fairing
03:41ushma kawaj ke awashaktah nahi rahti is liye se yaan se prithak kar diya jata hai
03:45aur abh yaan closed-loop guidance ke antar gat hai
03:48aur sata hi apna disha neradharan karra hai
03:50powered by the vikas engine that uses the earth storable propellant combination of UH-25 and N-204
04:02the second stage of GSLV develops 846 kilonewton thrust in vacuum
04:08burn time for this mission of GS2 is 140 seconds
04:16plus 4 minutes
