[5] Astrosat was successfully launched on 28 September 2015 from the Satish Dhawan Space Centre on board a PSLV-XL vehicle at 10:00AM.

While radio, optical, and IR observations would be coordinated through ground-based telescopes, the high energy regions, i.e., UV, X-ray and visible wavelength, would be covered by the dedicated satellite-borne instrumentation of AstroSat.

The observatory will also carry out: In particular, the mission will train its instruments at active galactic nuclei, which are believed to contain super-massive black holes.

A third 11-meter antenna at the Indian Deep Space Network (IDSN) became operational in July 2009 to track Astrosat.

The support cell has been set up to give opportunity to the scientific community in making proposals on processing and usage of AstroSat data.

[22] On 31 May 2017, Astrosat, Chandra X-ray Observatory and Hubble Space Telescope simultaneously detected a coronal explosion on the nearest planet-hosting star Proxima Centauri[23][24] On 6 November 2017 Nature Astronomy published a paper from Indian astronomers measuring the variations of X-ray polarisation of the Crab Pulsar in the Taurus constellation.

[26] In July 2018, Astrosat has captured an image of a special galaxy cluster that is more than 800 million light years away from Earth.

The galaxy called AUDFs01 was discovered by a team of Astronomers led by Kanak Saha from the Inter-University Centre for Astronomy and Astrophysics, Pune.

[33][34] In 2019 a documentary titled Indian Space Dreams on the developmental journey of Astrosat, and directed by Sue Sudbury, was released.
