- ISRO will launch its first polarimetry mission, the X-ray Polarimeter Satellite (XPoSat), possibly on January 1.
- It will become the country's third space-based observatory after the recently launched solar mission Aditya-L1 and Astrosat, launched in 2015.
- The goal of the mission is to study the "polarization" of astronomical X-rays, which can provide information about the processes that result in their emission.
- It is a method of studying astronomical phenomena in which, in addition to imaging them, fluctuations in light from a source and the energy emitted by celestial bodies are studied.
- The observatory can help understand emission mechanisms from sources such as black holes and neutron stars (collapsed core of a giant star).
