ISRO and various satellites and other space-related developments made by India are a very important segment of science and technology for the UPSC exam. India is fast becoming a successful country in the domain of space science and technology. ISRO has achieved several feathers to its cap and the Astrosat is one of them. In this article, you can learn about the Astrosat and what it means for Indian space research, with an IAS-perspective.
Astrosat is India’s first dedicated multi-wavelength space observatory. It was launched on a PSLV-XL on 28 September 2015. In 1996, the satellite-borne Indian X-ray Astronomy Experiment (IXAE) was launched and it proved successful. Buoyed by this development, ISRO started work for a full-fledged astronomy satellite named Astrosat in the year 2004. Astrosat performs multi-wavelength observations covering spectral bands from radio, optical, IR, UV, and X-ray wavelengths. Both individual studies of specific sources of interest and surveys are undertaken. 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.
