| May 2024 | XpoSAT, in collaboration with Aditya-L1 and Chandrayaan-2 Orbiter, collected critical scientific data during a massive Solar Flare event. The XSPECT instrument was used alongside ground-based observatories to provide fast-timed and high-quality spectroscopic results in the X-Ray spectra. |
| January 15 2024 | POLIX began scientific observations, starting with the first-ever x-ray polarisation data of the Crab Pulsar. The observation continued through January 18, monitoring the fast-spinning neutron star that releases approximately thirty X-ray pulses per second. |
| January 10 2024 | POLIX instrument on XPoSat was gradually turned on, preparing for scientific observations. |
| January 5 2024 | XSPECT payload on XPoSat captured its first light from Cassiopeia A (Cas A), a supernova remnant over 11,000 light years away. The observation captured emission lines of multiple elements including magnesium, silicon, sulphur, argon, calcium, and iron. |
| January 1 2024 | XPoSAT was successfully launched aboard PSLV-C58 at 9:10 am IST, with a precise launch achieving only a (±) 3 km deviation. The PSLV's 4th stage was subsequently dropped to a 350 x 350 km orbit to serve as PSLV Orbital Experimental Module POEM-3. |
| January 1 2024 | XPoSat was launched on a PSLV rocket by the Indian Space Research Organisation (ISRO), marking the beginning of India's X-ray polarisation space observatory mission. |
| September 2018 | Completed the Preliminary Design Review (PDR) for XPoSat, which included a comprehensive review of the POLIX payload design. |
| September 2017 | The XPoSat project was initiated by the Indian Space Research Organisation (ISRO), marking the beginning of the satellite development process. |
