'''PSLV-C35''' was the successful mission of the [[Polar Satellite Launch Vehicle]] program which set eight satellites in space. It was launched on 26 September 2016 by [[Indian Space Research Organisation]] (ISRO) from the [[Satish Dhawan Space Centre]] at [[Sriharikota]].

==Launch==
PSLV-C35 was launched at 03:42 hours [[Coordinated Universal Time]] (09:12 hours [[Indian Standard Time]]) on 26 September 2016 from the [[Satish Dhawan Space Centre First Launch Pad|first launch pad of Satish Dhawan Space Centre]] at [[Sriharikota]] in the Indian [[States and territories of India|state]] of [[Andhra Pradesh]].<ref name="PSLV-C35">{{cite news|title=PSLV-C35|publisher=[[ISRO]] website|accessdate=26 September 2016|url=http://www.isro.gov.in/launcher/pslv-c35-scatsat-1}}</ref><ref name="ISRO’s PSLV-C35 places SCATSAT-1 in orbit">{{cite news|title=ISRO's PSLV-C35 places SCATSAT-1 in orbit|work=[[The Times of India]]|accessdate=28 September 2016|url=http://timesofindia.indiatimes.com/india/Isros-PSLV-C35-places-SCATSAT-1-weather-satellite-in-orbit-mission-is-on/articleshow/54517632.cms}}</ref>

==Mission highlights==
PSLV-C35 was the 37th launch of the [[PSLV]] program. It was also the 102nd overall launch by [[Indian Space Research Organisation]]. PSLV-C35 was the first spaceflight by ISRO to place satellites in two different orbits with a single rocket. It carried and injected eight satellites built by India, [[Algeria]], Canada and United States.<ref name="PSLV-C35"/><ref name="PSLV-C35 brochure">{{cite news|title=PSLV-C35 brochure|publisher=[[ISRO]] website|accessdate=26 September 2016|url=http://www.isro.gov.in/sites/default/files/flipping_book/PSLV_C35_4/files/assets/common/downloads/PSLV%20C35%20Final.pdf}}</ref><ref name="ISRO timeline">{{cite news|title=ISRO timeline|publisher=[[ISRO]] website|accessdate=26 September 2016|url=http://www.isro.gov.in/about-isro/isros-timeline-1960s-to-today#102}}</ref>

==Payload==
PSLV-C35 carried and deployed eight satellites in two different [[orbit]]s in a single mission ([[Polar orbit|Polar]] and [[Sun-synchronous orbit]]). This was the first time India had placed satellites in two orbits in a single mission.<ref name="PSLV puts 8 satellites in two different orbits">{{cite news|title=PSLV puts 8 satellites in two different orbits|work=[[The Hindu]]|accessdate=28 September 2016|url=http://www.thehindu.com/sci-tech/science/isros-pslvc35-places-scatsat1-into-orbit-on-its-way-to-place-seven-others/article9149124.ece}}</ref> The vehicle carried three satellites from India ([[ScatSat-1]], [[PISat]] & [[Pratham (satellite)|Pratham]]), three satellites from Algeria ([[Alsat-1B]], [[Alsat-2B|2B]] & [[Alsat-1N|1N]]), one each from Canada ([[NLS-19]]) and the United States ([[Pathfinder-1]]).<ref name="PSLV-C35"/><ref name="PSLV-C35 brochure"/><ref name="ISRO PSLV-C35 launch">{{cite news|title=ISRO PSLV-C35 launch|publisher=[[Firstpost]]|accessdate=28 September 2016|url=http://tech.firstpost.com/news-analysis/isro-pslv-c35-launch-these-are-the-8-satellites-on-board-337090.html}}</ref>
