Five years of the launch of AstroSat has been marked by the Indian Space Research Organization (ISRO). This space mission was the India’s first multi-wavelength mission, that was launched from Sriharikota space-port on 28th September, 2018. The satellite is operating as a proposal based observatory system, covering a wide band ranging from Ultra violet to high energy X-rays.
while most of the satellites of ISRO is meant to serve purposes like imagery, remote sensing, surveillance, communication etc. A small number of missions/satellites are present to help in exploration of unexplored sciences and such missions are AstroSat, Mangalyaan and Chandrayaan.
Happy Birthday! #India’s first astronomy mission, the multi-wavelength space telescope called #AstroSat, has completed its 5-year mission life, but is likely to remain in space & generate valuable data for a few more years – @isro. https://t.co/w55HzI02Jx

According to the ISRO, unique observation capability of AstroSat makes it one of the best space science observatories in this world.
Indian Space Agency says that AstroSat is the only mission that led ISRO to the discovery of one of the earliest Galaxies of this universe in the presence of Extreme UltraViolet light, known as AUDFs01. This galaxy is said to be 9.3 million light years away from the earth.

Milestones Achieved by the ISRO
This discovery was led by Dr. Kanak Saha with a renowned international team at the Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune. This team included several scientists from India, Switzerland, France, Japan, USA and Netherlands.
R. Umamaheswaran, Scientific Secretary of ISRO on the account of a virtual event to mark five years of AstroSat mission said, the complete data that generated from AstroSat have been shared with 1500 people from 43 countries, turning this mission into an international success. He also said AstroSat was launched into a unique circular orbit with a lower incline of 6 degrees and five of its payloads were able to function simultaneously.
India’s #Astrosat space mission has opened up opportunities for new discoveries of the Universe and made space science data accessible to many scientists and students around the country, and world. Our most prolific space science mission till date! @isro @IUCAAScipop @asipoec https://t.co/l45eTz5IfO

Chairman of ISRO, DR. K.Sivan said that the study of this particular universe have opened the door for the defining research of ISRO. And most importantly AstroSat have brought them into a different level of space sciences and astronomical researches that provided stunning results to the institute. He also said, the satellite has been serving the mission since five consecutive years with five on board equipment on it in a very condition to serve a lot more in the years to come. Dr. Sivan referred this mission as a multi-agency mission where renowned foundations like academia and R&D institutions had worked together in the engineering and testing phase of this mission.
While talking about the ISRO’s big future plans Dr. Sivan proclaimed that Exposat and Aditya L-1 are the upcomimg mission of ISRO that would open the possibilities for something exciting. It is said that the Exposat is planned to explore the polarization of X-rays from the cosmic resources and this mission is going to be the first polarimetric mission after almost half century. Aditya L-1 has been scheduled to launch by mid 2020 and the main task of this satellite will be about studying the sun bit closely.
