Isro Plans To Launch India’s 2nd Space Observatory


Indian Space Research Organisation (Isro) is planning to launch the country’s second AstroSat-2 or space observatory. The mission is meant to further the study of astronomy (the study of celestial bodies) and astrophysics.

Isro made the announcement of opportunity on February 3 to seek proposals from all institutions currently involved in astronomy/astrophysics for the development of scientific instruments for astronomy payload and mission. The advantage of having such a space observatory in outer space is that it helps observe distant planets, galaxies and other astronomical objects more clearly than from the Earth. Space telescopes avoid problems of ground-based observatories, such as light pollution and distortion of electromagnetic radiation.

The first AstroSat-1 weighing 1,515kg was launched on September 28, 2015. It was successfully placed at an orbit of 650 km altitude and has a life span of five years. It circles around the Earth in 97 minutes and makes 15 rounds a day. The Rs 178-crore AstroSat-1 has five hi-tech cameras (payloads), which cover the energy bands of ultraviolet (near and far), limited optical and X-ray regime (0.3 keV to 100keV). The 2015 launch helped India gain entry into the select club of nations having its own observatory after the US, Japan, Russia and Europe. Read More…
