'''IRS-P2''' was an [[Earth observation satellite]] launched under the [[National Natural Resources Management System]] (NNRMS) programme undertaken by [[Indian Space Research Organisation]] (ISRO). The objectives of the mission were to provide spaceborne capability to [[India]] in observing and managing [[natural resource]]s and utilizing them in a productive manner. {{Clarify|date=May 2021|reason=What exactly does utilizing natural resources in a productive manner mean?}} The satellite carried imaging multi-spectral [[radiometer]]s on board for radio sensing of the resources.

== History ==
The satellite was designed, developed and tested in just one and a half years.<ref name="Hindustan">{{cite web|url=http://www.highbeam.com/doc/1G1-18846105.html |archive-url=https://web.archive.org/web/20150924150036/http://www.highbeam.com/doc/1G1-18846105.html |url-status=dead |title=India's IRS family comes of age (Indian Remote Sensing satellites)|newspaper=Hindustan Times|archive-date=September 24, 2015|date=1 August 1996|access-date=13 May 2021}}</ref> IRS-P2 is one of the satellites in the [[Indian Remote Sensing Programme]] of [[Earth observation satellite|Earth Observation satellites]], assembled, launched and maintained by the Indian Space Research Organisation.<ref name="ESA Online"/> The satellite was controlled by [[ISRO Telemetry Tracking and Command Network]] (ISTRAC) in [[Bangalore]], [[Lucknow]] and [[Mauritius]]. The [[National Remote Sensing Centre|National Remote Sensing Agency]] (NRSC), [[Hyderabad]] received the first signal from IRS-P2, 98 minutes after the launch. The IRS-P2 was declared operational from 7 November 1994 after certain orbital manoeuvres and started its 3-year-long observation mission.<ref name="yuga">{{cite web|url=http://spaceyuga.com/pslv-polar-satellite-launch-vehicle/|archive-url=https://web.archive.org/web/20120207035425/http://spaceyuga.com/pslv-polar-satellite-launch-vehicle/|url-status=dead|title=PSLV launch vehicle|archive-date=7 February 2012|access-date=13 May 2021}}</ref><ref name="Spacecraft">{{cite web|title=India (Launchers)|url=http://claudelafleur.qc.ca/Indians-launchers.html|publisher=Spacecraft Encyclopedia|access-date=13 May 2021}}</ref> The letter "P" indicates that the satellite was to be launched aboard a [[Polar Satellite Launch Vehicle]] (PSLV).<ref name="ESA Online">{{cite web|url=https://earth.esa.int/web/guest/missions/3rd-party-missions/historical-missions/irs-p3|publisher=ESA Earth Online|title=IRS-P3|access-date=13 May 2021}}</ref>
