'''EOS-02''' (formerly known as '''Microsat-2A''') was an Indian Earth observation [[Microsatellite (spaceflight)|microsatellite]] developed by [[ISRO]] as a test payload on the maiden launch of the [[Small Satellite Launch Vehicle]] (SSLV).<ref>{{Cite web|title=India's GISAT-1, Microsat 2-A, GSAT-12R, RISAT-2BR2 satellites ready for launch, says senior ISRO official|url=https://www.dnaindia.com/science/report-india-s-gisat-1-microsat-2-a-gsat-12r-risat-2br2-satellites-ready-for-launch-says-senior-isro-official-2843780|access-date=2022-02-14|website=DNA India|language=en}}</ref> EOS-02 was based on [[Microsat (ISRO)|Microsat-TD]]. The objective behind EOS-02 was to realize and fly an experimental imaging satellite with short turnaround time to showcase launch on demand capability.<ref>{{Cite web |date=2022-08-07 |title=India Completes Maiden SSLV Mission, ISRO Says Orbit Achieved Was 'Less Than Expected' |url=https://www.news18.com/news/india/india-completes-maiden-sslv-mission-isro-says-orbit-achieved-was-less-than-expected-5704285.html |access-date=2022-08-07 |website=News18 |language=en}}</ref><br />

It was intended to be used for [[cartographic]] applications at a [[cadastral]] level, urban and [[rural management]], coastal land use and regulation, utilities mapping, development and various other [[GIS applications]]. The satellite carried two payloads: a [[MWIR|mid-wavelength and a long-wavelength infared]] camera with a 6m resolution.<ref>{{Cite web|title=Annual Report 2019-20 (English)|url=https://www.isro.gov.in/sites/default/files/flipping_book/annual_report_2019-20_english/index.html|access-date=2022-02-15|website=www.isro.gov.in|archive-date=2020-04-06|archive-url=https://web.archive.org/web/20200406131804/https://www.isro.gov.in/sites/default/files/flipping_book/annual_report_2019-20_english/index.html|url-status=dead}}</ref><br />

EOS-02 was launched on [[Small Satellite Launch Vehicle]]'s maiden flight [[SSLV-D1]] at 03:48 [[Coordinated Universal Time|UTC]] / 09:18 [[Indian Standard Time|IST]] on 7 August 2022,<ref name="wion-20220630">{{cite web |url=https://www.wionews.com/india-news/isros-next-gen-rocket-sslv-to-have-maiden-launch-by-july-end-493369 |title=ISRO's next-gen rocket SSLV to have maiden launch by July-end |date=30 June 2022 |access-date=2 July 2022 |work=[[WION]]}}</ref><ref>{{Cite tweet|number=1554003107545092096|user=ISRO|title=The launch of the SSLV-D1/EOS-02 Mission is scheduled for Sunday, August 7, 2022, at 9:18 am (IST) from Satish Dhawan Space Centre (SDSC), Sriharikota.

As a result, both satellites onboard (EOS-02 and [[AzaadiSAT]]) were destroyed during reentry.<ref name=":9">{{Cite tweet|number=1556208112138215424|user=isro|title=SSLV-D1/EOS-02 Mission update: SSLV-D1 placed the satellites into 356 km x 76 km elliptical orbit instead of 356 km circular orbit. Satellites are no longer usable. Issue is reasonably identified. Failure of a logic to identify a sensor failure and go for a salvage action caused the deviation. A committee would analyse and recommend. With the implementation of the recommendations, ISRO will come back soon with SSLV-D2. A detailed statement by Chairman, ISRO will be uploaded soon.|author=[[Indian Space Research Organization]]|date=2022-08-07}}</ref><br />
