'''AstroSat-2''' is India's second dedicated multi-wavelength [[space telescope]], proposed by the [[Indian Space Research Organisation]] (ISRO) as the successor of the current [[Astrosat-1]] observatory, which has a five-year operation time ending in 2020.<ref name=TOI1>{{cite news|title=ISRO plans to launch India's 2nd space observatory|url=https://timesofindia.indiatimes.com//home/science/isro-plans-to-launch-indias-2nd-space-observatory/articleshow/62975636.cms?|archive-url=https://web.archive.org/web/20190201224032/https://timesofindia.indiatimes.com//home/science/isro-plans-to-launch-indias-2nd-space-observatory/articleshow/62975636.cms|url-status=dead|archive-date=1 February 2019|author=Surendra Singh|date=19 February 2018|newspaper=Times of India|access-date=5 April 2019}}</ref><br />

ISRO launched an 'Announcement of Opportunity' in February 2018 requesting proposals from Indian scientists for ideas and the development of instruments for [[astronomy]] and [[astrophysics]].<ref name=TOI1/><br />
