As of November 9, 2023, XPoSat was listed in a parliamentary Q&A as a payload originally scheduled to be launched by ISRO in 2023 aboard SSLV D3.
A public pre-launch statement referenced an anticipated mission life for XPoSat of around 5 years and target observation from Low Earth Orbit at approximately 650 km altitude and a low inclination around 6°.
Early forum posts listed XPoSat as tentatively planned for launch in Q4 2022.
A Times of India item described launch planning to target November–December (year implied 2023) for a PSLV carrying XPoSat and POEM on the same flight.
Public pre-launch media referenced PSLV-CA configuration being sufficient for XPoSat given its mass and target orbit, and other sources referenced a PSLV-DL configuration with two strap-on solid rocket boosters for the mission.
Public material from an XPoSat user meeting included a slide that identified the launch vehicle as PSLV.
XPoSat is a space observatory satellite being developed by the Indian Space Research Organisation and the Raman Research Institute.
An ISRO social media post listed the PSLV-C58/XPoSat launch as scheduled for January 1, 2024 at 09:10 Hrs IST from the first launch-pad at SDSC-SHAR, Sriharikota.
NextSpaceflight listed the XPoSat launch NET June 2024 (noting possible NET mid-2024/NET Q2 2024 schedule windows).
Public registration on the VSCREGISTRATION site listed PSLV-C58/XPoSat launch scheduled at 09:10 IST (03:40 UTC) on 1 January 2024.
The XSPECT (X-ray Spectroscopy and Timing) payload on XPoSat was developed by the URSC, ISRO.
A public pre-launch summary noted the PSLV final stage for the XPoSat mission would host 10 additional payloads after injecting the main satellite.
The POLIX (Polarimeter Instrument in X-rays) payload on XPoSat was developed by the Raman Research Institute.
A Polar Satellite Launch Vehicle lifted off at 10:40 p.m. Eastern 2023-12-31 (9:10 a.m. local 2024-01-01) from the Satish Dhawan Space Centre to launch the XPoSat spacecraft.
