New Delhi, Sep 22 (India Today): On September 28, India will be launching its first indigenous astronomy satellite called ASTROSAT to study heavenly objects. It was earlier scheduled to be launched in 2005, then delayed to 2010 and will be finally launched this year.

Four other institutions have joined ISRO in payload development. They are as follows:

Tata Institute of Fundamental Research

Indian Institute of Astrophysics

Inter-University Centre for Astronomy and Astrophysics

Raman Research Institute

Two of the payloads are made in collaboration with Canadian Space Agency (CSA) and University of Leicester, UK.

ASTROSAT is one of two scientific missions that have long been overdue - the other being the Aditya-1 mission to study the Sun. As part of the same mission, four other smaller American, one Indonesian and one Canadian satellites will also be launched.
The PSLVC-30 will carry the ASTROSAT along with six other foreign co-satellites.
