The '''Second Launch Pad''' ('''SLP''') of the [[Astronomy:Satish Dhawan Space Centre|Satish Dhawan Space Centre]] is a rocket launch site in [[Place:Sriharikota|Sriharikota]], {{wipe|India}}. It is the second of two launch pads at the centre. The Second Launch Pad (SLP) was designed, supplied, erected & commissioned by MECON Limited, a Government of Indian Enterprise, located at Ranchi (Jharkhand, India) during the period March 1999 to December 2003.<ref>{{cite web |url=http://www.meconlimited.co.in/FlashNews/Chandrayaan.pdf|title=Archived copy|accessdate=2013-09-03|url-status=dead |archiveurl=https://web.archive.org/web/20131220171630/http://www.meconlimited.co.in/FlashNews/Chandrayaan.pdf|archivedate=20 December 2013|df=dmy-all}}</ref> It cost about {{INRconvert|400|c|year=2005|lk=on}} at that time.<ref>http://www.telegraphindia.com/1081023/jsp/jharkhand/story_10006297.jsp</ref> The second launch pad with associated facilities was built in 2005. However it became operational on 5 May 2005 with the launching of PSLV-C6. MECON's sub-contractors for this project including Inox India, HEC, Tata Growth, Goderej Boyce, Simplex, Nagarjuna Construction, Steelage, etc. The other Launch Pad being the [[Astronomy:Satish Dhawan Space Centre First Launch Pad|First Launch Pad]]. It is used by [[Engineering:Polar Satellite Launch Vehicle|Polar Satellite Launch Vehicle]]s, [[Engineering:Geosynchronous Satellite Launch Vehicle|Geosynchronous Satellite Launch Vehicle]]s, Geosynchronous Satellite Launch Vehicle Mk.III and is intended for [[Engineering:Gaganyaan|India's first manned space mission]].<ref name="ISRO-LF">{{Cite web |url=http://www.isro.org/GroundFacilities/launchfacility.aspx|title=Launch Facility|publisher=Indian Space Research Organisation|accessdate=12 April 2010|url-status=dead |archiveurl=https://web.archive.org/web/20100417071046/http://www.isro.org/GroundFacilities/launchfacility.aspx|archivedate=17 April 2010|df=dmy-all}}</ref><ref>{{Cite web|title=SDSC SHAR/Sr.HPS/PT/RO/11/2019-20|url=https://www.isro.gov.in/sdsc-shar-srhps-gt-ro-11-2019-2020|date=November 7, 2019|accessdate=November 22, 2019|publisher=Indian Space Research Organization|website=www.isro.gov.in}}</ref>

== Launches ==
The first launch from the pad occurred on 5 May 2005, and was of a Polar Satellite Launch Vehicle carrying the CARTOSAT-1 and [[Engineering:HAMSAT|HAMSAT]] satellites.<ref name=ea20100412>{{Cite web |url=http://www.astronautix.com/sites/sritaslp.htm|title=Sriharikota SLP|last=Wade|first=Mark|publisher=Encyclopedia Astronautica|accessdate=12 April 2010}}</ref> India's 1st Moon Mission, Chandrayan-I was launched from this launch pad on 22 October 2008. Its follow-up mission [[Astronomy:Chandrayaan-2|Chandrayaan-2]] was also launched from this launch pad on 22 July 2019. The most recent launch was of a PSLV-XL on 27 November 2019.

The full list of launches from the complex is in the article [[Astronomy:List of Satish Dhawan Space Centre launches|List of Satish Dhawan Space Centre launches]].

== Facilities ==
"As per the "Integrate, Transfer and Launch (ITL)" concept, based on which the launch pad and the associated facilities are designed, the entire vehicle is assembled and checked-out on a mobile pedestal in the Vehicle Assembly Building (VAB) and then moved in vertical position to the launch pad on a roll track."<ref name="PDT">Public domain text sourced from the link - [http://www.isro.org/GroundFacilities/launchfacility.aspx ISRO Launch Facilities] {{webarchive|url=https://web.archive.org/web/20100417071046/http://www.isro.org/GroundFacilities/launchfacility.aspx|date=17 April 2010}}</ref>

"Other facilities include, Solid Stage Assembly Building (SSAB) connected to the Vehicle Assembly Building (VAB) by a rail track, Technical Complex-2 (TC2), Spacecraft Preparation Facility, Range Instrumentation facilities comprising tracking, telemetry and tele-command systems".<ref name="PDT"/>

A new assembly building (SVAB - Second Vehicle Assembly Building) being constructed with a budgetary grant of {{INRconvert|630|c}} is nearing completion and is expected to be ready by mid 2018.{{update inline|date=August 2018}} This upgrade is expected to increase the launch capacity of second launch pad complex to 11 launches per year.<ref>{{cite web|url=http://www.prajasakti.com/Article/Nellor/2004423 |title=PIF Project|publisher=Prajasakti}}</ref>
