**ISRO’s XPoSat Satellite Now Open to Indian Scientists: What You Need to Know**
The Indian Space Research Organisation (ISRO) has officially opened its X-ray Polarimeter Satellite (XPoSat) mission for proposals from Indian scientists and researchers. This marks a significant opportunity for India’s astronomy community to utilize cutting-edge space-based observation tools.
**About XPoSat**
XPoSat operates in a near-equatorial orbit at an altitude of 650 km and is equipped with two advanced scientific payloads. Among these, the XSPECT (X-ray Spectroscopy and Timing) instrument plays a key role by providing spectroscopic and timing data in the 0.8 to 15 keV energy range.
**Observation Time and Proposal Submission**
In the first cycle of observations, ISRO has reserved 60% of the observatory’s time exclusively for Indian researchers. Observation sessions will be conducted from January to December 2026, offering a full year of research opportunities.
Indian scientists interested in submitting proposals can do so through the XPoSat Proposal Processing System (XPPS) available on the Indian Space Science Data Centre (ISSDC) website. The deadline for submission is November 30, 2025.
**Who Can Apply?**
This opportunity is open to Indian astronomers and researchers affiliated with institutions, universities, and colleges across India. Principal Investigators (PIs) must demonstrate their technical capability to analyze the data generated from the satellite if their proposals are accepted.
**Evaluation and Support**
All proposals will be reviewed by the XPoSat Time Allocation Committee (XTAC) based on scientific merit and technical feasibility.
To assist applicants, ISRO has provided comprehensive technical resources, including the XSPECT User Handbook and proposal preparation tools like XPoViewer. These resources help researchers determine satellite visibility periods and prepare strong submissions tailored to their targets of interest.
This initiative by ISRO is set to provide a significant boost to India’s space science and astronomy research, allowing scientists to explore the cosmos using India’s very own satellite observatory.
